Title: Improvements in automatic dispensing systems
Inventor: ASPER THEODOR
IPC: G07F15/00
Filed: 1969-01-02
Abstract: 1,249,680. Automatic dispensing system. T. ASPER. 2 Jan., 1969 [5 Jan., 1968], No. 238/69. Heading G4V. In a credit vending system pulses transmitted from a key storing monetary values cause goods or services to be dispensed while the store is simultaneously devalued. Delivery ceases under the control of a customer or when the store becomes completely devalued and ceases to generate pulses. Indicating means on the token show how much credit is still available, or alternatively how much has been used. In a particular embodiment for dispensing petrol the credit is shown by an odometer movement 4-8, the digits 9 being visible through windows 10, 11 in the case 1. The movement is driven via shaft 12 passing through the tang 3 of the key. A cogwheel 13 drives the lowest denomination wheel 4 of the odometer, the cogwheel 13 and shaft being axially displaced against the action of spring 16 by a projection 17 on wheel 4 each time it revolves. On placing the key in the dispenser the money registering system of the latter drives the key counter via a spur gear, and continues to do so until the axial pulses of shaft 12 (caused by projection 17) cease. This occurs when the counter reaches zero, and the mechanism either locks, or drum 4 moves to let projection 17 clear the shaft end 15, or the shaft is axially displaced, or the drive is interrupted (e.g. by a slipping clutch or by disengagement of wheels 13 and 14). Shut off may be effected by magnetic valve (28) (Fig. 3, not shown) when the pulses stop. Provision is made to prevent fraudulent resetting of the monetory value of the key. An alternative key (Fig. 2, not shown) comprises a plurality of discs with digits on the surfaces thereof. Windows in the face of the key head allow the value present to be read off.

Title: Improvements in and relating to switching circuits
IPC: H03K23/80
Filed: 1963-01-02
Abstract: 1,025,441. Semi-conductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 2, 1963 [Jan. 15, 1962], No. 246/63. Heading H3T. [Also in Division G4] A switching circuit, e.g. for producing sharp pulses comprises two tunnel diodes X 10 , X 2o . Fig. 2, having series load resistors R 1 , R 2  respectively, connected in parallel across a supply: resistor R 1  is smaller than R 2 , so that more current flows through diode X 10  than diode X 20 . Increasing the current supplied causes diode X 10  to trigger to its high resistance state increasing the current through diode X 20 , and producing the leading edge of the output pulse E out , Fig. 3, after the inherant delay time of a tunnel diode, diode X 20  switches its state producing the trailing edge of the pulse E out . A backward diode B.D. may be connected in the output circuit to present positive overshoot at the end of the pulse. In a second embodiment, Fig. 4, a number of tunnel diodes Xa ... Xe are connected to form a sequential register resistor Ra1 is of lower value than the others, so that its first triggering pulse switches diode Xa to its high resistance condition, but leaves the others unchanged. The change in resistance of diode Xa increases the standing bias on diodes Xb so that the next triggering pulse will switch this diode and increase the bias on Xc ready for the third pulse, and so on until all diodes are switched. The " sequencing " property may be employed in a word recognition circuit, Fig. 6. Detectors of strong frictioning Fs voicing V and weak frictioning Fw are connected to word recognition blocks each of which comprise tunnel diode registers of the type described above. The circuit of Fig. 4 may be modified to form a counter, Fig. 7 (not shown) by connecting all the trigger inputs to a common pulse source so that each pulse to be counted changes the state of one diode. The circuit of Fig. 2 may be used as the source of pulses for such a counter.

Title: Improvements in or relating to electric circuit interrupters having arc extinguishing devices
IPC: H01H33/76
Filed: 1941-01-09
Abstract: 544,152. Gas-blast switches; actuation of switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 9, 1941, No. 334. Convention date, Jan. 23, 1940. [Class 38 (v)] A gas-blast switch comprises a movable contact 33 separable from a fixed contact 17 in an arc-chute 13 and subjected to a cross blast through a hollow supporting insulator 11 from container 7. Contact 33 is pivoted at 35 and operated by a link 53 and lever 49 from a fluid motor 43, the lever 49 having an extension 59 which opens the blast valve 63 during the closing and opening switch movements. The chute, Fig. 2, comprises side plates 21 and end plates 23, 25, and leads into a passage 69 comprising walls 27, 29 and members 67, Fig. 3 arranged so that the passage rapidly widens from the point about halfway across the contacts. Space plates 73 of gas-forming .material extend into the neighbourhood of the arc and have notches 75 into which the arc is blown and so kept away from the walls of member 67. The lower ends of the plates 73 fit in grooves in the latter and are tapered so as to provide parallel-sided passages 77 at those ends. Insulator 11 contains a nozzle 65 which directs the blast, at the velocity of sound, so as to prevent it spreading when it leaves the nozzle during the interruption of low currents, at the tip of the plate 73 which is nearest the fixed contact 17. The arc is thus forced against the edges of and between, the plates 73, excessive penetration into the chute being prevented by metal plates 79. The gas produced by the arc on plates 73 may be excessive at heavy currents but the pressure at the nozzle 65 is relieved by the space between the arc in the upper parts of the notches 75 and the diverging wall of members 67, so allowing removal of the ionized arc gases from behind the arc. The degree of divergence and separation between the plates 73 varies through the chute, as does also the number of metal cooling grids 81 which are made concave towards the arc so as to keep the gases away from the plates 73.

Title: Improvements in and relating to transverse flow type blowers
IPC: F04D17/04
Filed: 1961-01-05
Abstract: 953,003. Transverse-flow blowers. T. HELMBOLD. Jan. 5, 1961 [April 25, 1960; Nov. 18, 1960], No. 473/61. Heading F1C. In a transverse-flow blower, a cylindrical flow guide member 8 is arranged within the blower impeller 1 within the region opposite to an external partition 4 separating the inlet 2 from the outlet 3, the member 8 being rotatable in a free or a driven manner. The use of a rotary guide member instead of a stationary one avoids boundary layer separation and formation of whirls. If its rotation is in the opposite direction to that of the impeller, it improves the flow distribution within the outlet and reduces the noise. The member 8 may, as shown, be mounted on an arm 9 which can be pivoted about the blower axis to bring the member 8 into the most favourable position. The member 8 may be a plain cylinder without blades and may be driven through an infinitely variable V-belt or frictional drive.

Filed: 1919-01-09
Abstract: 137,583. Marks, E. C. R., (Cheney Talking Machine Co.). Jan. 9, 1919. Periodic; applied by springs.-Relates to automatic stop-mechanism for talking-machines, of the kind in which the stop member, brake or switch, is brought into operative position by a spring upon the release of a latch by the tonearm, and consists in operating the latch by a trigger lever frictionally connected to the arm that is engaged by the tone-arm. Fig. 2 is a plan view showing the brake lever latched in its in. operative position. The brake lever 18 has a friction pad 20 and a handle 38, and is pivoted on a pin 19 to the base-plate 4. Two shoulders 25, 27 on a lever 18 co-operate with corresponding projections cn a latch member 23 also pivoted to the base-plate 4. A trigger lever 26, fitting loosely in the forked outer end of the latch, is pivoted on a pin 28, and is frictionally connected to the operating arm 29, which is pivoted on the same pin 28 and has an upstanding outer end 41. The frictional connexion comprises an arm 32 of the operating-lever 29, overlying an arm on the trigger lever 26, the two arms being pressed together by a spring surrounding the bolt 34. A segmental slot is provided on the upper arm 32, to enable the position of the operating-lever to be adjusted relatively to the trigger 26. In the position shown in Fig. 2, the brake is held off by the engagement of a projection on the latch 23 with the shoulder 25 on the brake lever. When the tone-arm reaches the final groove of the record, a member 13 moving with the tone arm engages the end 41 of the operating-lever 29, and after a certain delay due to the lost motion between the trigger 26 and the latch 23 the latter is tripped and the brake block 20 is brought into engagement with the inner side of the turntable rim 22 by means of a spring 21. The spring is attached at one end to a lug on the brake lever and at its other end to a lug on the trigger. Initial setting is effected by moving the arm 29 over to the left, placing the tonearm in its final position, and then moving the arm 29 by hand until it reaches the member 13 attached to the tone-arm. During the setting operation, the pin 40 forms an abutment for the trigger 26. The arm 13 is attached by a screw 11, and lugs 15, 16 to a tubular member 10 which surrounds the stationary socket 8 and is connected to the tone arm elbow by the screws 11 and 12 which move in slots in the socket 8. In a modification adapted for electrically-driven machines, the lever 18 has no brake block, but is provided with an arm, the outer end of which bridges a pair of fixed contacts in the motor circuit during the running of the machine, and opens the motor circuit when the machine is to be arrested.
