Title: Improvements in machines for sorting statistical cards and the like
Filed: 1922-04-22
Abstract: 201,222. Last, J., and Accounting & Tabulating Corporation of Great Britain, Ltd. April 22, 1922. Compiling and tabulaling statistics mechanically.-Sorting mechanism of the kind in which the shutters of the sorting compartments are opened at appropriate times by timing devices according to the perforations on the cards is provided with improved timing devices in which the settable elements are separate from the means which operate the shutters and allow these means to function only at the correct moment. Each card 4 is traversed through the machine by discs 1 driven through bevel gears 2, 2a which make one revolution for each card passing. A shutter 5 to each compartment 6 is carried by a shaft 8 rigid with a collar 9, a sleeve 11 and a co-axial spindle 10. A lever 14 freely rotatable on the sleeve 11 is rocked by a crankpin 15 on the wheel 2a and carries a pawl 16 having a wide nose 16<1>, Fig. 2, which engages with a ratchet wheel 17 freely rotating on the sleeve 11. The flange of the collar 9 has a ratchet-shaped notch 18, the radial face of the notch opposing the nose 16<1> which engages therein whenever it is permitted to engage with the teeth 19 of the wheel 17 to their full depth. This wheel 17 is also slotted radially on the side remote from the lever 14 to receive plungers 20 half of which are normally supported upon a stationary semi-annular track 21 at any instant with their ends protruding into the gap between two teeth 19 so that the nose 16<1> cannot enter the gap to its full depth and therefore cannot engage in the notch 18 of the collar 9 to turn the shaft 8 and operate the shutter 5 when the lever 14 is rocked. These plungers 20 may be displaced outwardly before reaching the track 21 by a cam 41 and then pass over a trip 29 which is so positioned that a plunger 20 supported by it has bearing on its outer end the nose of a check pawl 27. When a hole in a card is sensed by the pin box 24, 23 the Bowden wire 22 of the timing unit of the appropriate sorting compartment is actuated so that the ferrule 39 is raised, rocking the bell-crank 37 and moving a sleeve 35 carrying the trip 29 to the right, Fig. 2, so that the plunger 20 supported by the trip 29 at the moment is pressed inwards by the pawl 27 and retained in its inner position by the track 21 so that one or more card cycles later, according to the number of the sorting compartment with which corresponds the number of teeth 19 between the pawls 16, 27, the nose 16<1> can pass to the full depth of the gap between the teeth 19 and thus into the notch 18 to rotate the collar 9 and shaft 8 and therefore raise the shutter 5 of the compartment. The tooth 19 is moved forward at each cycle so that the delay is proportional to the number of teeth between the pawls 27, 16 and this number may be adjusted by means of a setting plate 34<1> carrying the pawl 27 and a slotted member 30 co-operating with the card box partition 32.

Title: Thermionic direct current amplifiers
IPC: H03F3/36
Filed: 1949-04-29
Abstract: 669,064. Valve amplifying circuits. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. April 29, 1949 [April 30, 1948; April 28, 1949], Nos. 11460/49 and 11461/49. Class 40 (vi). A direct current amplifying arrangement for the double-polarity output signal from an impedance bridge comprises a valve whose anode current energizes the bridge and which is periodically cut-off by rectangular switching pulses for short correction periods, a direct current amplifier and a zero drift correction circuit connected in parallel with the output meter of the arrangement and having gating means operated by pulses coincident with the switching pulses to cause the output of the amplifier during correction periods to charge a condenser connected to an electrode of an amplifier valve so as to reduce the zero drift and to cut off a valve in the charging circuit between correction periods. As shown, Fig. 1, the elements 6, 7, 8, 9 of a strain-gauge bridge are energized by the anode current of a valve 2, which is cut off during correction periods by rectangular pulses applied to its grid. The D.C. output of the bridge is fed to the first stage of a push-pull amplifier. During correction periods, any change in the anode voltage of a valve 37 in the last stage causes a condenser 59 to charge through valve 50. A second valve 54, in shunt to condenser 59, provides a discharge path to prevent valve 50 being cut off. The voltage appearing across condenser 59 is applied to the grid of valve 60, the cathode of which feeds a correcting voltage to the anode of one valve 21 of the first stage. During measurement periods the valves 50, 54 are cut off by the flow of anode current in the sections of double valve 42, which are cut off during correction periods by rectangular pulses applied to the grids. In a modification, Fig. 3 (not shown), correcting voltages are applied to both valves of the first stage, from two opposed condensers, each with an individual charging valve controlled by the anode voltage of one valve of the final stage. In this case, it is unnecessary to provide a discharge path for each condenser. Specifications 620,140, and 633,551 are referred to.

Abstract: 351,619. Ventilating vehicles. NEILSON, T. and MARSHALL, J., 11, Cogan Street, Pollokshaws, Glasgow. April 11, 1930, No. 11494. [Class 137.] In a ventilation system for rail vehicles &c., the vitiated air is passed through a heat exchanger, further heated or cooled, and again passed through the exchanger to exchange heat with the incoming vitiated air before being returned to the vehicle spaces to be ventilated. The air in the compartments C of a rail vehicle is drawn through valves 4 into a duct 5 having a filter 8 and communicating with a junction 6 having a valve 7 for controlling the flow of the vitiated air and of atmospheric air through a branch 9 having a filter 8a to a heat exchanger 10a, Fig. 3. The air is drawn from the heat exchanger, in which, in this case, it is partially cooled, by a fan 12 and forced through the duct 14, a cooler 10b, and the heat exchanger 10a to a duct 15 having a moisture separator 16 and communicating with a duct 17 having nozzles 19, such as those described in Specification 282,323, [Class 137, Ventilation], for directing the air into the compartments. In the cooler, the air is cooled to the dew point corresponding to the relative humidity finally required, while in the heat exchanger it is reheated under thermostatic control. The supply of treated air to the compartments may either be controlled by the occupants or automatically by thermostatic means. A refrigerating plant is mounted on the vehicle. In a modification, the air cooler may either be combined with or replaced by an air heater. Specification 346,527 is referred to.

Title: Automatic golf ball teeing device
IPC: A63B57/00
Filed: 1942-08-17
Abstract: 556,704. Golf-ball teeing devices. MOZEL, J. Aug. 17, 1942, No. 11519. [Class 132 (ii)] In a device for automatically teeing golf balls, particularly for use in teaching and practising, the tee 19 is reciprocated vertically by a motor and spring operated lever 7 so as to pick up a ball delivered to a support 51 from a pivoted shoot 48. The motor 38 is energized through a switch 24 each time the tee is freed from the weight of a ball driven therefrom. To lower the tee, the motor, acting through speed reduction gearing, rotates a wheel carrying a roller 33 engaging the lever 7. The motor circuit is maintained until the cycle of movements is completed, by a switch mechanism 63 closed by a cam 64. The height of the tee is adjusted by raising or lowering a stop 43 by means of a knob 45. If there are no balls in the pivoted shoot 48, a spring 53 and a spring in a switch 52 raise the shoot and open a contact thereby preventing the closure of the motor circuit, the machine then becoming non-operative and a signal lamp being lit to indicate that more balls are required. A detent 70 rocked by mechanical connections with the lever 7 admits the balls singly to the support 51. The tee 19 is carried by a body member of rectangular crosssection reciprocating within a cylindrical housing 4, thereby reducing the risk of binding.

Title: Apparatus for use in depositing articles in a receptacle and a seqeuence controller utilized therein
IPC: G05B19/07
Filed: 1974-03-15
Abstract: 1441180 Automatic control BURROUGHS CORP 15 March 1974 11611/74 Heading G3N A tellerless bank depositing apparatus, Fig. 1, is responsive to a deposit key 8 which, when depressed, initiates a sequence whereby a fascia door is opened by an actuator 10 monitored by a sensor S1. Lamps 24 are then lit in a display circuit 26 to indicate that a deposit made be made into a chute 2. The fall of a deposit envelope actuates a jam sensor S5 and a sensor S2 when it comes against an outlet gate 6. At this point the fascia gate closes and the lamps 24 extinguished. An incrementing printer 14 is then operated by an actuator 16 to record the envelope. The operation of the printer is monitored by a sensor S3 and the gate 6 is opened by an actuator 20, monitored by a sensor S4, and the envelope allowed to fall into a safe receptacle 22. The sequence of operations, Fig. 3 (not shown), is controlled by a shift register SR which provides stage outputs ST1-ST7 which are used to enable input NAND-gates G2-G8, to control the actuators and display directly, or through NOR-gates, and reset the shift register. Each gate G1-G8 is enabled by the completion of the previous operation and responds to the signal from a sensor or a time delay device, not shown, to provide a signal through a clocking circuit 41 which steps the register. At the end of a sequence the shift register is reset and the gate G1 enabled by a signal ST o  provided by a flipflop FF2 responsive to the output of a circuit 38. A deviation from the desired sequence is determined by an error circuit 39 which terminates the sequence through the circuit 38.
