Title: Improvements in or relating to apparatus for the manufacture of pneumatic tyres
IPC: B29D30/24
Filed: 1932-02-10
Abstract: 383,814. Wheel tyres. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London. Feb. 10, 1932, No. 3957. Convention date, Feb. 14, 1931. [Class 144 (i).] In tyre-making apparatus wherein a tyre casing is built up flat upon a rotating drum operated by a friction drive, the control for the friction drive controls also means for operating upon the casing and/or braking means for the drum, and incorporates resilient means such that the various operations are effected by the progressive actuation of a single handle or pedal. As shown, the drum 6 is adapted to be driven by an internal continuously rotating friction wheel 11 which is mounted on a bell crank 9 pivoted at 8. The end 12 of the bell crank 9 is located between a weak spring 18 secured to the main framework and a strong spring 17 connected through links 14, 15, 16 to a pedal 13. The other end of the bell crank 9 abuts against a stop 27 on a pivoted brake-arm 24, this brake normally being held in contact with the drum against the action of a spring 26 by the spring 18, which also holds the rotating wheel 11 clear of the drum. A stop 23 on the link 14 is adapted to engage the end 22 of an arm 19 carrying a roller 21 for consolidating the tread. The stops 23, 27 are so adjusted that depression of the pedal first releases the brake arm 24, then brings the wheel 11 into engagement with the drum, the spring 17 serving as a rigid link during this stage ; when the wheel 11 is in engagement, further depression of the pedal extends the spring 17 and brings the roller 21 into operation. The inner surface of the drum may be lined with rubber or other suitable material for the engagement of the brake and driving wheel. In addition to the main roller 21, further pairs of rollers 28, 29 are provided for rolling down the bead &c., these rollers are mounted on a spring-pressed pivoted arm 30 which may be lifted out of engagement by a cam 35 on a hand-lever 33. The rollers 29 are provided with a spring mounting 36, and serve to roll down the edges of the casing. Sharpened rollers for trimming may also be provided. In the example given, the casing is built up inside out.

Title: Improvements in or relating to electric relays for use with alternating current of variable frequency and voltage
IPC: H02H7/093
Filed: 1942-03-25
Abstract: 550,611. Electromagnetic relays motor control systems. IGRANIC ELECTRIC CO., Ltd., and RANDALL, C. E. March 25, 1942, No. 3958. [Classes 38 (iii) and 38 (v)] A relay 7, Fig. 2, responsive to both frequency and voltage and particularly adapted for interrupting the primary circuit of an A.C. slip ring motor when, as the result of " plugging," the motor reaches substantially zero speed, is supplied from a source 8, 9 through a condenser 10. The motor control circuits are shown in Fig. 1. Closure of switch 3 completes circuit to the forward' contactor 1 of the motor which thereupon starts up in the forward direction. Contactor 1 also opens contacts 1b and closes at 1a the circuit to a relay 5 which closes ' maintaining' contacts 5a and prepares at 5b the circuit to the' reverse' contactor 2. To stop the motor switch 4 is opened. This breaks circuits of forward contactor 1 which now opens contacts 1a and closes contacts 1b to the ' reverse' contactor 2. This, in addition to energizing the motor for reverse running, causes coil 5 to be short circuited at 2a whereupon contacts 5a, 5b open. Contactor 2 remains energized however because when the plugging' takes place, the rise of voltage in the motor secondary energizes the relay 7 through a circuit 14, 7b across terminals 8, 9 of one phase of the secondary, so that contacts 7a are closed. Contacts 7b are also opened but the relay 7 is now maintained ' through the frequency and voltage responsive circuit 12, 10. When therefore the motor speed reaches zero, relay 7 opens contacts 7a and the motor is de-energized. An ammeter 13 may be arranged as shown. Compensation for variations in supply voltage may be provided by connecting between points 16 an inductance which automatically varies with the supply voltage, Fig. 3 (not shown). Instead of having both an operating and a maintaining circuit for the relay 7, the contacts 7b may be arranged to add capacity to the condenser 10 so that the circuit 12, 10, 7 would constitute both the operating and maintaining circuit.

Patent GB-936900-A (GB)
Title: Method of preparing superconductive elements
IPC: G11C11/44
Filed: 1962-02-02
Abstract: 936,900. Cryotrons. SPERRY RAND CORPORATION. Feb. 2, 1962 [Feb. 10, 1961], No. 4097/62. Classes 37 and 41. A cryotron memory element is made by electroplating tin, lead or other metal having superconductivity character on each side of a substrate metal which has comparatively high ohmic resistance and no super conductivity character, e.g. copper and copper/nickel alloys. For example a glass base-plate 8, Fig. 2, has a coating of lead 12 acting as earth plane on which is mounted a plating of constantan 13, a plating of tin 2. another layer of constantan 14, and a final plating through a mask of a narrow strip of lead conductor 3, about 0.006 inch wide. The tin " gate " is 0.125 inch wide. Alternatively the lead strip may be formed by etching a lead plating through a mask. Other metals which may be used as ohmic resistance layers are nickel/chrome alloys, and other super-conductive metals are V, Cb, and Ta. Two such elements may be used in the circuit. Fig. 1, 5 and 6 being super-cooled tin " gates," connected through a narrow lead conductor to a tin " gate " 2 and separated therefrom by a layer of ohmic resistance. The conductor 3 is also connected to one edge of a tin " gate " 7. The other edge of the tin gate 2, a lead conductor 4 passes cross tin " gate " 7 also separated therefrom by a layer of ohmic resistance. Two other conductors 10, 11 pass across the gates 5, 6. Leads 1 and 9 are constant current sources. The circuit is a bi-stable arrangement as a high current in lead 4 creates a sufficient magnetic field to render tin gate 7 non-superconductive, all gates being maintained at a temperature at which tin is super-conductive in the absence of a magnetic field a high current through lead 11 renders gate 6 non-superconductive, and current in lead 4 drops, allowing gate 7 to become super-conductive, and tin gate 2 becomes no longer super-conductive. A pulse applied to lead 10 momentarily renders gate 5 non-super-conductive, and gate 6, which has reverted to super-conductive state, causes current surge through gate 2, now superconductive, and closes gate 7, thus forming the flip-flop cycle. Such a circuit includes the feature of grounded gates when not superconductive.
