Title: Improvements in or related to attendande recorders
Inventor: CLARK JOHN I
IPC: G07C1/06
Filed: 1969-07-01
Abstract: 1,243,307. Attendance recorder. MITE CORP. 1 July, 1969 [5 Nov., 1968], No. 33243/69. Heading G4T. An attendance recorder for use with a time card having columns for each day of the week, and rows for different times of the day, comprises clock 22 (Fig. 2) operated print wheels 23 and a cardholder 28 that are relatively movable across the columns to change the day of the week; and time controlled means that shifts the card across the rows and comprises a timer 52 which operates a ratchet sector 44 through a feed pawl 50, a shift arm 40 carried by said ratchet sector to control the card position, knock-off means 72 to disengage the feed pawl and return the card to a starting position, and releasable look means 114 (Fig. 3) to secure the shift-arm 40 and knock-off means 72 at desired angles to the ratchet sector 44. As described, the print wheels 23 (Fig. 2) and the card holder 28 are manually movable horizontally to position the wheels over an appropriate column on an inserted card. Depression of a handle 36 forces the time card and a slowly moving ink ribbon 24 against the type; alternatively automatic printing may be actuated by a contact at the base of the time card. Card positioning vertically.-The arcuate tip 64 (Fig. 3) of the shift arm 40 is moved vertically at fixed times during a day to align one of six rows representing IN, IN LATE, OUT, IN, IN LATE, OUT on an inserted card, successively with the print wheel 23 (Fig. 2). The face of a 24-hour timer 52 carries at said fixed times brass inserts 58 which close a contact 60 and momentarily energize a solenoid 46, so producing .downward movement of the feed pawl 50, the ratchet sector 44 being restrained by a check pawl 68 (Fig. 3). On de-energization of the solenoid, the pawl 50 pivots the ratchet sector 44 upwards about an axis 42 under the action of a spring 66. After the final required row has been printed, a subsequent energization of solenoid 46 brings the pawl 50 against a projection 70 on the knock-off sector 72, to disengage the pawl 50, and also the check pawl 68 through co-operation between an attached pin 82 and a slot 144 in a latch 130. The latch 130 then holds both pawls in disengagement until the shift arm 40, ratchet sector 44 and knock-off sector 72 return to their starting positions against a stop 108. The check 68 and feed 50 pawls are released again on a subsequent energization of solenoid 46. The shift arm 40 and knock-off sector 72 are releasably locked to the ratchet sector 44 by a screw 114 and nut 120 respectively (see also Fig. 9, not reproduced). Their angles to the ratchet sector determine the positioning of the initial and final printing rows respectively on the card, and their relative angle determines the number of rows, up to sixteen, that can be printed.

IPC: D03D45/20
Filed: 1948-12-29
Abstract: 718,691. Hydraulic machines. MUNSTER SIMMS & CO., Ltd. July 20, 1950 [Dec. 29, 1948; Oct. 1, 1949], Nos. 33453/48 and 25297/49. Class 69 (2). [Also in Group IX] Control valve mechanism, Fig. 5.-A jack is fed by a pump 20 which delivers a pulse of fluid at regular intervals, the pulse being directed to opposite ends of the jack alternately by a reversing valve 14 operated by cam mechanism 44 which is rotated intermittently by a ratchet 46. Just before a pulse is due, the cam mechanism depresses a bye-pass valve 15, thereby blocking openings 56, so that the fluid passes through one or other of passages 27 leading to the jack. The bye-pass valve is held down against its spring 54, by overcentre action of a spring 67 on a bell crank lever 61 linked to the valve plunger; the valve is tripped back to the position shown, after the pulse has passed, by a cam 64, whereby the jack is short-circuited to the reservoir 12; consequently if the cam mechanism has not been turned when the next pulse occurs, pressure is not applied to the jack. Instead of controlling it by the cam mechanism 44, the reversing valve 14 can be operated regularly by a cam 70, which is brought into action by sliding the pivot 73 of a bell-crank lever 69 inwards so that the lever contacts the cam ; the upper arm of the lever permanently engages the end 68 of the valve plunger; when this control is in use, the bye-pass valve is put out of action by turning it through 90 degrees. Jack, Fig. 12.-Spring-loaded plungers 29, one at each end of the cylinder, snap into the relevant groove 40 when the piston 31 reaches the ends of its stroke. The jack is unlocked by fluid entering the port 30, which first lifts the plunger, then moves the piston. Excess fluid arriving after the piston reaches the end of its stroke escapes to the reservoir through a relief valve 35.

Title: Improvements relating to telephone and like signalling systems
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q1/32
Filed: 1955-11-25
Abstract: 803,973. Automatic exchange systems. SIEMENS EDISON SWAN, Ltd. Nov. 20, 1956 [Nov. 25,1955], No. 33877/55. Class 40 (4). In an arrangement whereby indications of the condition of an impulsing circuit (i.e. dialled impulses intertrain pause and release) are required to be transmitted only during a specified period in a cycle, the indications are transmitted by a cold cathode tube whose anode is pulsed during the specified period, and which is enabled when a counting-device reaches a marking position, the counting device being started by the onset of the condition and stepped by pulses occurring between said specified periods. Such requirements are necessary where the indications are to be received by circuits employing cold-cathode tubes which are extinguished by the use of " pulsed anode " techniques. As shown, Fig. 2, closure of loop LA, LB operates relay A and B, BA. Operation of B applies - 250 v. starting potential to wires C which sets counting tubes VI, V7 to position 11 and strikes V4, the subsequent rise of potential towards earth being controlled by the network C19, R49. The potential of wire C is ultimately clamped to earth by contact bal. At each end release and reoperation of A, relay AA applies a momentary earth pulse to wire D to cause self-extinguishing tube V6 to apply pulses to the bi-stable pair V4, V5 which fire alternately, and also to fire the self-extinguishing tube V3 whose output causes tubes V1 and V7 to fire on position 1. Tube V5, which thus always fires at the beginning of a break, applies inhibiting potential to the second cathode of V7 to prevent this tube stepping. Tube V1, however, steps under the influence of pulses PA (which occur during the intervals between the prescribed periods). On a normal dial impulse the glow on tube V1 has time to reach position 3 (but not position 10) before the next pulse on wire D due to the termination of the break. The cathode pulse in this position endures during the subsequent PB period to allow tube V2 to fire and pass a pulse in this period via wire W1 to suitable registering equipment. If the break is a long one (due to release) when the glow on tube V1 reaches position 10, valve V9 is enabled to pass a PB pulse over wire W2. Tube V4 fires at the beginning of a make period, V3 firing at the same time to restore the glow to position 1 on both tubes V1, V7. In this case V4 applies inhibiting potential to the second cathode of VI to prevent it stepping but V7 is permitted to step. If the make period is greater than the inter-train pause the glow reaches position 10 where it causes tube V8 to emit a PB pulse over wire W3.
