Abstract: A drawer retraction mechanism comprises a guide member 20, a holding member 50 for holding and releasing a drawer mounted pin, and elastic means 90 for pulling the holding member 50 along the guide member 20 into a retracted position. The guide member 20 has two side walls each formed with a step 28,30, and a locking formation 42 on an end portion 32 of the guide member. The holding member 50 is slidably mounted on the guide member 20 and comprises first and second supporting members [54,56, Fig. 2] for engaging opposing sides of the guide member. The first supporting member comprises: a first leg [54a, Fig 2] which engages the step 28 on a first side of the guide member and which is able to engage with the locking formation 42; a second leg [54b, Fig. 2] which also engages the step 28; and a recess 58 defined between the two legs which allows the holding member to pivot relative to the guide member when the second leg is moved away from the step 28 and into engagement with the locking formation 42 as the holding member moves to an extended position. The second supporting member comprises a supporting plate [56, Fig. 2] which engages the second side wall [22d, Fig. 2] of the guide member, and a third leg [56, Fig. 2] which holds against the step 30 on the second side wall. The holding member 50 further comprises a pin slot 64 which, in use, is able to engage and retain the drawer mounted pin [17, Fig. 15] . When the pin moved into the slot 64 the first leg is moved out of contact with the locking formation 42 allowing the elastic member 90 to retract the holding member. The slot 64 may be of a first depth and the recess 58 of a second depth, the first depth being less than the second depth. A buffer device [86, Fig. 17] may be used with the retraction mechanism.

Title: Event logging apparatus
IPC: G11B15/10
Filed: 1974-03-06
Abstract: 1469166 Event recording EDMAC ASSOCIATES Inc 6 March 1974 10019/74 Heading G5R Event logging apparatus has means for receiving a magnetic tape cassette 10 and for transporting the tape thereof, a magnetic head 13 for recording on the tape, a current reversal flip-flop 7 arranged to reverse the direction of current flow through head 13 each time that the flip-flop 7 is triggered, a timer 6 connected to trigger the flip-flop 7 when the timer 6 receives an input signal more than a predetermined period after the last received input signal, an event detector 1, 3, 5 providing an input signal to timer 6 each time an event to be logged is detected, and a switch 15 operable to cause the apparatus to log events. A handle 14 is operative to pivot an arm 11 carrying the head 13 and a pinch roller 20 into an operative position in which the tape is driven, e.g. at 0À001 inch/sec., by a capstan shaft 18, formed by the output shaft of a motor/gear-box 17, onto a take-up reel rotated by a slip clutch 98. The switch 15 is operated by arm 11 and controls power supply to motor 17 and to the electronic circuits. The cassette 10 may be ejected by a lever 104 which is locked in an inoperative position by a plate (101), Fig. 4 (not shown), engaged in a notch 103 of lever 104 by means of handle 14 when moved to shift arm 11 to the operative position. An interlock operated by the cassette 10 may be provided to prevent operation of the apparatus unless the cassette 10 is properly aligned. A first recording channel I has an amplifier 3 which receives an input from an event transducer 1 and an event detector 5 gives an output pulse for each signal from amplifier 3 above a threshold, such output pulses passing to the pulse rejection timer circuit 6 formed by a oneshot multivibrator which is reset on each input pulse so that only input pulses spaced by more than the period of the timer give rise to corresponding output pulses; this prevents a single event which gives rise to a rapidly fluctuating output from transducer 1 being recorded as multiple events. The current reversal flip-flop 7 responds only to the leading edge of the pulses from timer 6, each such pulse changing the state of the flip-flop 7 and thus reversing the current flow direction through a first track winding of head 13. A pair of lamps (74), Fig. 2 (not shown), are alternately energized via SCRs from the output of flip-flop 7 to indicate the state thereof. A second recording channel II records digital data on a second track of cassette 10 and has a shift register (81), Fig. 3 (not shown), with a serial data input and a parallel data input. A clock (84) controls register (81) and a phase encoder (90) which receives data from register (81) and converts it into a bi-phase mark selfclocking code. A head driver (94) receives the output of encoder (90) and provides a constantcurrent bipolar signal to head 13 whereby the data is recorded as a pattern of flux reversals. The signals to be recorded on the second track may originate from an external badge reader or a time clock.

Title: Improvements in or relating to prepayment mechanism for electricity and other meters
IPC: G07F15/08
Filed: 1943-06-26
Abstract: 568,100. Prepayment mechanism for meters. ARON ELECTRICITY METER, Ltd., and RIORDAN, E. J. June 26, 1943, No. 10361. [Class 27] Price-change mechanism for electricity and other meters, of the kind having a first gear member comprising a plurality of concentric gear rings, any one of which can be engaged by a slidable second gear member, is characterised in that the first gear member comprises a pair of concentric gear ring members, each engageable by a separate second gear member, means such as a differential being provided to summate the movements of the two second gear members. In the construction shown, the first gear member 1 has two sets of concentric gear rings 2, 2a on its opposite faces and is driven by a pinion 25 from the meter element, the prepayment mechanism, or a constant speed motor. A second gear member 4 is adapted to engage any one of the gear rings 2 and is carried by a lever 6 slidable along a bar 8, the gear 4 being locked in any of its gear positions by the engagement of the lever end 11 in one of a series of notches 12 in a plate 13. Another second gear member 4a adapted to engage any one of the gear rings 2a is carried by a second lever engaging notches 12a in the plate 13. The gear 4 meshes with a long pinion 19 driving the planet pinion 21 of a differential, and the gear 4a meshes with a long pinion 19a driving a sun-wheel 23 of the differential through gearing 22. The other sun-wheel 24 drives the meter cut-out (not shown). Thus, the differential sums up the drives from the two sets of gear rings 2, 2a, and as the gear trains from the gears 4, 4a are of different ratios, one may represent charges in pence per unit and the other in eighths of a penny per unit, so that variations in price may be made from oneeighth of a penny by eighths up to several pence per unit. The lever 6 is kept in place in any selected notch 12 by a spring 14. The gear 4 is formed with a crown wheel 15 which engages a pinion 16 on the shaft 3 of the gear member 1 when the lever end 11 is in one end notch 121a. When the gear 4 is at the other end of its adjustment it engages a fixed plate 17 and is locked thereby ; in both end positions it is out of gear with the gear rings 2. An indication of the settings of the two gears 4, 4a may be provided opposite the slots 12, 12a.

Title: Improvements in permanent magnetic chuck
IPC: B23Q3/154
Filed: 1941-08-15
Abstract: 551,329. Magnetic work-holders. BEECHLYN, J. T. Aug. 15, 1941, No. 10414. [Class 60] A work-holder comprises two insulated pole-elements in connection with a system of permanent magnets, a portion of the system being movable to reverse part of the flux for the purpose of releasing the work held by the poleelements. The workholder shown in Figs. 1 and 2 comprises top and bottom sections 10, 12, and a section 16 having plates 42 arranged between grid-bars 24 on the top section and insulated therefrom by soft metal 46, the plates and grid-bars constituting pole-elements for holding the work. Permanent magnets 20, 22 are arranged between the sections 12, 16, the magnets 20 being fixed, and the magnet 22 consisting of magnets 47, 48 bolted to caps 54 which are rotatably mounted in depressions 32, 40 in the sections 12, 16. The magnet 22 is provided with end-caps having handles attached thereto. The magnet 22 is preferably stronger than the magnets 20, the difference in strength being produced by employing magnets of different sizes, or by arranging their non- magnetic plates across some of the magnetic circuits. When the magnet 22 is so positioned that the upper pole is the same as that of the magnets 20, the fluxes of the magnets are additive, and a powerful work-holding flux passes through the pole-elements and the work. Since the return path of the flux is through the top and bottom sections, there is no tendency for chips to collect. When the magnet 22 is so positioned that the upper pole is different from that of the magnets 20, the flux is considerably reduced, the polarities of the elements 24, 42 are reversed, and the work is released. In a modification, the magnets 20 are arranged to transmit the flux laterally, and the magnet 22 consists of two separately rotatable magnets interconnected by linkage or gearing.
