Patent GB-354691-A (GB)
Title: Improvements in or relating to selector systems
IPC: H03J5/18
Filed: 1930-02-05
Abstract: 354,691. Distant control systems. VICTOR TALKING MACHINE CO., Corner Street, Camden, New Jersey, U.S.A. Feb. 5, 1930, No. 3953. Convention date, Feb. 5, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (i).] In a selective control system, more particularly for setting a wireless set in tune to any one of a number of transmitting stations, a shaft is selectively positioned by an electric motor under the control of a plurality of detents co-operating with corresponding notched discs mounted on the shaft. As shown in Fig. 1, a wireless set 11 is selectively tuned by a shaft 17 driven through a slipping friction clutch 23 and worm gearing 21, 22 by an electric motor 16. The shaft carries notched discs 24 .. 27, Fig. 2, with which co-operate detents 29, 33, 34, 35. Each disc is set to correspond to a particular station by means of the split hub 31 and clamping screw 32 which allow a free manual adjustment of the disc relatively to the shaft 17. The detents are provided with electromagnets 40 .. 43, Fig. 3, selectively controlled by corresponding pushbutton switches 47 .. 50. When it is desired to tune to a particular station the corresponding pushbutton is depressed to energize the appropriate electromagnet which attracts its detent against the action of the control spring 38. The motor is started in a series circuit and the shaft 17 is rotated until the attracted detent engages the notch in the corresponding disc. The motor continues to rotate and the clutch 23 slips until the operated pushbutton is released. In a modification the selected magnet may be maintained energized independently of its pushbutton over contacts 62 operated by the detent. This holding circuit may be interrupted either by opening the circuit 63 or short-circuiting the magnet through auxiliary contacts 65. In order to render the wireless set inactive during setting, the output or input of the set may be short-circuited at contacts 58 closed by the detents. The detents may be operated manually, operation thereof simultaneously starting the motor. Operating pushbuttons may be provided both at the wireless set and remotely in as many locations as desired, the line wires of the buttons being connected to the mechanism and the supply by connectors 56, 57 such as plug- and-socket devices.

Title: Collapsible threading device
IPC: B23G5/14
Filed: 1941-03-26
Abstract: 548,303. Collapsable taps. LANDIS MACHINE CO. March 26, 1941, No. 4084. Convention date, April 3, 1940. [Class 83 (iii)] Collapsable taps of the type described in U.S.A. Specification 2,028,075 are provided with improved tripping and resetting mechanism. The cam core 13 is adjustably located with respect to a plunger 18 by means of a screw 20 having a serrated head co-operating with a correspondingly located spring plunger 21 held from rotation by a pin 40. A key socket 41 provides for adjustment the serrations being such as to permit this but prevent accidental rotation. A tension spring 50 connects the plunger 18 to a screw-adjusted nut 52 in such manner that the tension is adjustable. A latch 23 pivoted on a cross pin 24 in the body 10 has a locking surface 23b concentric with the pin and engaging a complemental surface 25a on a reversible latch plate 25b. The plunger has slots 64 to clear the pin 24. The movement of the latch prior to the time of disengagement does not affect the setting of the chasers and production of unwanted taper threads is avoided. The set position of the latch is determined by an abutment 23c and a spring-controlled key 31 with rack teeth engages a toothed segment 23a to maintain the latch in operative position and return it to this position whenever permitted. Release of the chasers is effected by a sliding sleeve 26 that, in the case of a rotary tap, is yoke operated at 60. The sleeve carries the key 31 with lost motion permitted by slots 27a, 33a and opposed by the spring 32. A cross pin 36 carried by the sleeve passes through slots in the body and engages the plunger 18 by a slot permitting limited lost motion. On the opening movement the abutment 23b is held clear of the surface 25b to reduce wear. On reversal of the sleeve to reset the tap the spring 32 is first compressed bringing the abutment thereon on to the surface ready to snap into locking position after the plunger has been returned by the pin 36.

Abstract: 928,437. Speed-responsive switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 26, 1962 [Feb. 3, 1961], No. 4174/61. Class 38 (5). A switch has a moving contact 10 carried by an L-shaped spring arm 4 pivoted at 16 to the insulating switch body 1 and carrying an insulating stud 14 on one limb 15, the stud 14 being engageable by an axially displaceable collar 21 of a centrifugal mechanism 18 (secured to the rotor shaft 19 of a motor 20) to deflect the contact-carrying limb 15 towards a fixed contact 11. The other limb 8 of arm 4 is twisted out of the general plane of the spring arm by anchoring it to a surface 9 of an abutment on the switch body 1 which surface is inclined relatively to the general plane of the arm when the latter is bearing against a backstop 5. Movement of the limb 15 to operate contacts 10, 11 increases the torsion in limb 8 by a determinable amount, so that the spring arm 4 can be pre-set during assembly of the switch to operate the switch at a precise motor speed. A hollow cylindrical extension 22 of the moulded switch body 1 shrouds the contacts 10, 11 and the centrifugal mechanism 18.

Abstract: 837,927. Valves. ROSS OPERATING VALVE CO. Feb. 11, 1958 [May 9, 1957], No. 4470/58. Class 135. A reversible metering valve device comprises a housing having first and second flow ports communicating with a bore of the housing, a check valve carried in a hollow cartridge which is reversibly positioned in the bore and registers with the first and second ports so that flow through the cartridge between these ports is checked alternatively in one or the opposite flow direction by reversing the cartridge end for end, and an adjustable by-pass restriction connected between the first and second ports and effective to provide a metered flow through the device in the direction in which the flow is otherwise checked by the check valve. As shown, the invention is applied to the operation of a spring-loaded piston 14 requiring to be given slow outward and quick return strokes or vice versa for the operation of a main valve (not shown). The device 10 comprises a head or housing 11 bolted to a cylinder 13 of the main valve and having a first port 18 for connection to a source of operating pressure or to exhaust and a second port 19 which registers with a port 20 of the cylinder 13. These ports communicate with a bore 23 of the housing in which a hollow cartridge 26 carrying a ball check valve 48 is reversibly mounted. Ports 49, 53 of the cartridge on opposite sides of the check valve register, as shown in Fig. 2, and also when the cartridge is turned end for end, with the first and second ports 18, 19 so that the valve operates to check flow in the chosen direction between these ports and permit a free flow in the reverse direction. A by-pass orifice 35 connected between the ports 18 and 19 and adjustable by a tapered needle 36 is effective to provide the restricted metered flow through the device in the direction in which the flow is otherwise prevented by the check valve, i.e. corresponding to a slow outward or alternatively a slow return stroke of the piston 14, the complementary stroke in either case being a rapid one. The cartridge is sealed in the bore by three sealing rings 42 and retained by a set screw 54.
