Title: A new or improved electrical control system for controlling the operation of a liquid dispensing apparatus such as a petrol pump in conjunction with a till or register
Inventor: SOMERSCALES ROBERT WILFRED
Filed: 1950-04-11
Abstract: 708,621. Dispensing liquids; controlling sales. RAWSTHORNE, L. B., [trading as RISBOROUGH SERVICE & FILLING STATION]. April 11, 1951 [April 11, 1950], No. 8885/50. Class 116 [Also in Groups XIX and XXXVII An electrical control system, designed to ensure registration of a sale from a petrol pump or other liquid dispensing apparatus. comprises a control device which becomes effective, upon restoration of the delivery nozzle to its rest, to prevent a further delivery until the control device has been reset by the action of a contact device operated manually; or by a till or cash register. In Fig. 1, the circuit of a motor M operating a liquid-fuel dispensing pump is normally open at contacts associated with the delivery-nozzle arm 19 and includes normally-closed contacts 1 of an electromagnetic switch. Removal of the nozzle closes the motor circuit to commence delivery; additional contacts 18 are also closed to energize a solenoid 11 which retracts a piston 10 in a cylinder 9. When the nozzle is replaced and the contacts 18 re-open, the piston 10 is returned by a spring 12 and develops pressure in the cylinder 9 for a period controlled by an adjustable exhaust valve 13. This pressure lifts a plunger 8 causing temporary closure of contacts 6 which energizes a winding 4 of the electromagnetic switch to open the contacts 1. Further operation of the delivery motor M is therefore prevented until the charge has been registered, whereupon contacts 20 are closed, e.g. automatically by operation of a cash-register, and energize a second winding 3 of the electromagnetic switch to reset the contact 1 closed. Parallel contacts 5 and 14a, associated respectively with the electromagnetic switch and solenoid 11, light a warning lamp 16 when a charge is due to be registered. In the simplified apparatus of Fig. 2, closure of the delivery-nozzle contacts 21 completes the motor circuit over normally-closed contacts 24a, 24c of a relay 24 and through the winding of a relay 25 which thereupon holds-up and maintains the motor circuit at contacts 25a. Contacts 25b of relay 25 also close and energize relay 24 which switches contact 24c from 24a to 24b, so holding relay 24 energized and preventing re-closure of the motor circuit once it has been opened at the nozzle contacts 21. Contacts 28 are opened when the charge is registered and this restores relay 24 to prepare the motor circuit at contacts 24a, 24c.

Title: Transmitting aerial with automatic tuning, particularly for aircraft wireless
IPC: H01Q1/30
Filed: 1945-04-16
Abstract: 599,387. Wireless transmitting systems ; aerials. AUTOPHON AKT.-GES. April 16, 1945, No. 9509. Convention date, Dec. 24, 1943. [Class 40 (v)] A wireless transmitting _aerial especially for aircraft use, is automatically tuned by means of a motor drive controlled by the aerial current. The aerial A is wound on a drum T, being connected to the transmitter (not shown) via the brush SK and current transformer STW. The drum T is driven by the motor M through the magnetic clutch Kp and worm gear Sgl, and itself drives the disc carrying contactors U, V by means of the worm gear Sg2. To unwind the aerial A contacts a1 are momentarily closed and contacts a2, a3, opened. The relay L, which is self-latching over contacts l1, then closes contacts l2, l3, energizing the motor M and clutch Kp. The aerial A is unwound until the,contactor U momentarily reverses the contacts uk, energizing the relays K, S which latch in over contacts k1, s2, and de-energizing the relay L. Opening of the contacts l2, l3 and closure of the contacts k3, k4, then causes rewinding of the aerial to commence. As the length of the aerial A approaches the resonant value, an increasingly negative bias is applied from the diode V1 to the valve V2, causing the condenser C to charge over the resistance R and polarized relay P, the contacts s2 being in reverse position due to the energization of the relay S. On passing resonance, discharge of the condenser C causes the relay P to open the contacts p1 and de-energize the relays K, S thus stopping the motor M. When it is required to retune the aerial, the contacts a1, a2, a3 are again operated, thus re-initiating the above described sequence. To retract the aerial, the contact r1 is momentarily closed and contacts r2, r3 opened, energizing the relay K to close contacts k1, k3, k4. When fully wound, the contactor V opens contact V1 to de-energize the relay K. The contacts r1, r2, r3 may be operated automatically upon lowering the undercarriage. According to the Specification as open to inspection under Sect. 91, the aerial may alternatively be tuned by means of variable inductance or capacitance controlled as described above. This subject-matter does not appear in the Specification as accepted.

Abstract: 913,263. Teleprinter systems. SIEMENS & HALSKE A.G. March 17, 1960 [March 17, 1959], No. 9555/60. Addition to 847,166. Class 40 (3). A teleprinter system including a transmitter relay operable to transmit a pulse train formed by teleprinter signal combinations, means for causing the automatic transmission of pulses at regular predetermined intervals when the teleprinter is in its idle condition and means for giving an indication when neither the idle state pulses nor the teleprinter pulse combinations are being received, incorporates means for giving an indication when the distortion of the received idle state pulses or of the teleprinter pulse combinations exceeds a predetermined level. As shown, subscribers of exchanges VSt1, VSt2 linked by a line Ltg, are connected by group selectors GW1, GW2. In the idle state of the connected teleprinters the contacts u11, u12, u13, u21, u22, u23 are in the positions shown and generators IG1, IG2 of idle time signals operate contacts b1 b2 of respective relays B1, B2 to pass the idle time pulses to evaluators AW1, AW2 of the exchanges. If signals are not received, an evaluator, for example AW2, passes a pulse by means of contact r2 and u12 in the position shown to operate evaluator AW1 to block its associated line against use. During telegraphic traffic the the contacts u11, u12 ... are switched over, and signals in one direction are passed via contact b1 of relay B1 and contact a2 of relay A2 to the connected subscriber of the exchange VSt2. In this direction, signals passed by contact a2 are also passed by contact u23 in the position opposite to that shown to the signal evaluator AW2, which in case of transmission failure passes a signal from contact r2, contact a1 of relay A1 and contact u13 (now closed) to AW1 to block the existing connection. The signals passing to the evaluators, e.g. AW2, are also passed via a switch connection as22 to a signal distortion equipment BVM2 connected to a distortion evaluating device VAW2 associated via a selector switch as21 with an indicating lamp SL2 corresponding to the outgoing subscriber line connected to the exchange VSt2. Instead of, or additional to, the lighting of the lamp SL2, the connection to the subscriber may be blocked.

Filed: 1945-04-18
Abstract: 602,173. Coated fabrics. SYLVANIA INDUSTRIAL CORPORATION. April 18, 1945, No. 9646. Convention date, April 22, 1944. [Class 140] Waterproof fabric is produced by applying to each side of an open mesh textile fabric a film of an organic hydrophobic thermoplastic material supported on a temporary backing sheet, causing the films by heat and pressure to adhere to the yarns and fuse together in the meshes and stripping off the backing sheets. Examples of open mesh fabric, which may be formed by weaving, knitting, netting or crocheting, are scrim, cheesecloth, bobinet, crinoline and fabrics formed of organic thermoplastic fibres. The transfer film may be formed of such materials as cellulose derivatives, vinyl and acrylic polymers and interpolymers, coumarone and indene resir.s, polymers of dienes, olefine-polysulphides and iso-olefines, and thermosetting resins in the thermoplastic state, such as phenol aldehyde, urea - formaldehyde, allkylated urea - formaldehyde, melamine - aldehyde sulphonamide - aldehyde and alkyd resins and resins formed from dicarboxylic acids and diamines. The backing sheet, which may be in the form of a sheet, web or endless belt, is formed of or coated with a hydrophilic material such as regenerated cellulose, cellulose ethers, gelatin, zein, denitrated nitrocellulose, deacetylated chitin or infusible resins. The transfer film may be formed on the backing by applying the thermoplastic material as a solution or molten mass by spraying or dipping and calendering. As shown, backing sheets 10 each carrying a transfer film 11 are fed between the rolls 13 to enclose a web 12 of open mesh fabric. The assembled sheets are then passed around the heated drum 14, being pressed against it by the blanket 15 which travels about the pressure rolls 16 and tension rolls 17, when the films are caused to adhere to the fabric and to fuse together. Stripping of the backing sheets by the stripping rolls is facilitated by first cooling in the chamber 18. The films on either side of the fabric may differ in colour and chemical constitution and the products may be used for tents, raincoats and liquid containers. Specification 580,883 is referred to.
