摘要： A cam and follower arrangement in which the cam consists of a track carried by a rotatable member. The track has one or more abrupt directional transitions (17) and the follower (17) is biassed to engage one wall or the other (21) of the track (21) appropriate to the direction of rotation of the member by means including a direct-current electric motor operated in a stalled condition. The arrangement may be employed in a monochromator for spectrophotometric apparatus to drive a filter-holder to position one of a number of optical filters arranged in the incoming beam of light.

摘要： An Ebert monochromator for a spectrophotometer in which the diffraction grating is positioned off of the central optical axis of the collimator mirror by interpositioning a plane mirror between the collimator mirror and the diffraction grating. The plane mirror may be movable to select one of several diffraction gratings. By arranging the diffraction grating about an axis parallel with the central optical axis, a simple mechanical wavelength drive system with a common cam shaft driving the grating, a filter holder, and a rotatable slit plate can be provided. Further gratings may be driven from the cam shaft as may also the movable plane mirror which selects them.

摘要： A dual beam spectrophotometer includes a radiation chopper, a monochrometer, and a diffraction grating moved by a stepper motor. The chopper includes a gate pulse generator which produces gate pulses G.sub.S and G.sub.R corresponding to periods during which radiation from the source passes through a sample cell and a reference cell respectively. A stepper motor drive circuit produces pulses to step the stepper motor which are synchronized with the chopping cycle by means of the G.sub.R and G.sub.S pulses. The stepper motor is arranged to step an equal number of times in each half of a chopping cycle. A further condition which is preferably satisfied is that the first pulse of a sequence should start in the opposite half of the chopping cycle from that in which the first pulse started in a previous chopping cycle. At low stepping rates the motor will step twice in one chopping cycle and then pause for several cycles before again stepping twice.
摘要翻译：双光束分光光度计包括辐射斩光器，单色仪和由步进电机驱动的衍射光栅。斩波器包括门脉冲发生器，其产生对应于来自源的辐射通过样本池和参考单元的周期的栅极脉冲GS和GR。步进电机驱动电路通过GR和GS脉冲产生脉冲以步进与斩波周期同步的步进电机。步进电机被布置成在斩波周期的每一半中相等次数。优选满足的另一个条件是序列的第一个脉冲应该在斩波周期的相反一半开始，其中第一个脉冲在先前的斩波周期中开始。在低步进率下，电机将在一个斩波周期中步进两次，然后暂停几个周期，然后再次步进两次。

摘要： An improved guard for a medical cartridge, such as a unit dose pre-filled glass syringe, comprising a body for receiving the cartridge, and a shield slidably attached to the body which are pre-assembled and ready to receive a cartridge therein. The body has a locking mechanism on a proximal end thereof which holds the cartridge therein. The body and shield have cooperating detents and detent pockets which allow the shield to be directed distally, from an unguarded position in which the needle on the cartridge is uncovered for delivery of medication, to a guarded position in which the needle is permanently covered for disposal. The body may also include a substantially rectangular-shaped finger grip on its proximal end for receiving a similarly shaped proximal flange on the cartridge, whereby the cartridge is received in a predetermined orientation. The body may also include one or more ribs within the cavity for accommodating a cartridge with a large needle cap, such as a 0.5 mL capacity pre-filled syringe. In addition, the guard may include a finger grip plug lockably attachable to the proximal end of the body, and a plunger insertable through the finger grip plug to engage a piston in a cartridge not having its own plunger. The plunger may include a one-way locking member to prevent removal of the plunger from the finger grip plug after assembly.

摘要： There is disclosed herein a blood collection tube holder having a body and a protector case, and preferably with a dedicated needle attached to the body. The tube holder is molded of plastic or other suitable material which is sterilizable. The device comprises five parts including the body, protector case, needle, needle protective cap, and a needle boot. The protector case is mounted over the body, and the needle is attached to the body and extends through an opening in the protector case. The needle is covered by the needle protective cap which is removably attached to a needle hub on the end of the body. The needle protective cap is removed for use, and after use the protector case is moved with respect to the body until detents engage openings to thereby lock the protector case in a position shielding the needle. The construction of the holder is such that the practitioner can hold the protector case against the arm of a patient with the index finger and draw the body of the holder rearward with the thumb and forefinger, thereby enabling use with one hand.
