Title: Coupling for connecting together a plurality of rods or tubes
Inventor: LITTLE PETER RAYMOND
IPC: F16B7/04
Filed: 1967-08-16
Abstract: 1,246,795. Rod and tube couplings. BOARD OF GOVERNORS OF THE BETHLEM ROYAL HOSPITAL & MAUDSLEY HOSPITAL. 15 Nov., 1968 [16 Aug., 1967], No. 37745/67. Heading F2G. [Also in Division A4] Rods or tubes 5 of light metal alloy, e.g. aluminium, are assembled into a rigid framework for use e.g. as a display-supporting framework in a shop window, by coupling members each of which comprises two or more, e.g. two to six, elements 1 which are formed integrally by a moulding of resilient plastics material having bores to receive the rods or tubes 5 and including integral lugs 22 between which is received a plastic fitting 24 moulded on to the end of a diagonal brace rod or tube 23. Each rod 5 preferably has a groove, as shown, which co-operates with a reduced diameter portion of each of the bores to retain the rod thereon. Grooves are also preferably provided in the end portion of the brace rod 23 prior to moulding of the fitting 24 thereon.

Title: Electrical automatic speed control system
Inventor: BANCROFT NORMAN ROY
IPC: B66C13/23
Filed: 1959-11-06
Abstract: 948,941. Clutch control. PYE Ltd. Nov. 3, 1960 [Nov. 6, 1959], No. 37747/59. Heading F2L. [Also in Division G3] A winch drum is driven by a constant speed motor through induction couplings 2, 3, which are adapted to rotate an output shaft in opposite directions, the arrangement being such that, when one coupling is energized to transmit the drive, the other coupling is energized to act as a dynamic brake if the speed of the shaft exceeds a predetermined value. A hoist control circuit 9 comprises thyratrons V 1 , V 2 , which are biased by A.C. derived from transformer T 1  and also by a D.C. error signal which represents the difference between the voltage from tachometer generator 8, driven by the output shaft, and a reference voltage from potentiometer P 1 . The lowering control circuit 11 is similar to the circuit 9 and comprises thyratrons V 3 , V 4 . Balance potentiometers P 3 , P 2  are provided for each control circuit 9, 11, respectively, a balance potential being applied to that circuit which at any time is controlling the coupling functioning as a brake. In this manner, braking action of the associated coupling is initiated when the driving torque of the other coupling approaches zero. Relays 10, 12, ensure that the output shaft is locked by a magnetic brake 7 unless one of the couplings is energized. A single controller may regulate change-over switch contacts SA-SF and also adjust the potentiometer P 1 . During the hoisting operation, an error signal indicating underspeed causes increased excitation of coupling 2, the same signal being applied to thyratrons V 3 , V 4 , with opposite polarity to prevent torque being generated by coupling 3. If the potentiometer P 1  is moved to a lower tapping, the thyratrons V 1 , V 2  are cut-off and the thyratrons V 3 , V 4  become fully conductive so that coupling 3 provides dynamic braking. When a light.load is being lowered, the coupling 3 provides the driving torque, whereas, with substantial loads, the coupling 2 is always energized to provide a braking torque. If the load tends to overhaul, further driving by the coupling 3 is prevented and the coupling 2 provides a negative torque to maintain a set lowering speed. Specification 871,437 is referred to.

Abstract: 341,234. Stays for box lids. THOMPSON, J., 104, Piercy Street, Newtown, Wednesbury, Staffordshire. Dec. 14, 1929, No. 38323. [Class 65 (i).] A stay for the hinged lids of boxes and the like consists of two arms d, i pivoted to the lid and the box respectively ; the pivot e of arm d is arranged to resist rotation, while the arm i is free on its pivot. The arm i carries two pins m, p, and the arm d has a slot n in which the pin m slides. As the lid is opened, the pin m moves into the branch 2 of the slot n, and, after full opening, slight closing brings the notch o in the end of arm d on to the pin p to support the lid, the pin m moving into the main part of the slot. Further opening brings pin m into the part 1 of the slot, and on closing the lid the end of arm d swings clear of the pin p. A spring tending to close the arm i inwardly may be added.

A plastics barrel 11, e.g. for beer, has a bunghole 12 closed either by a screw-threaded stopper 13 or a flanged stopper 3, Fig. 3, and a weakened part 7 to provide a tap hole.

Title: Improvements in gas supply controlling means for domestic and similar water heaters
IPC: F23N1/08
Filed: 1957-12-12
Abstract: 849,318. Fluid-actuated valves. LOMAX, W. Dec. 10, 1958 [Dec. 12, 1957], No. 38605/57. Class 135. A diaphragm-actuated water heater gas valve wherein one side of the diaphragm is subject to suction caused by flow of water so that the valve is opened when water is flowing is characterized in that the space on the said side of the diaphragm is connected to a zone of decreased pressure created in the water outlet pipe and in that at a predetermined outlet water temperature steam or water vapour causes an increase of pressure in said space to allow the valve to be closed by a loading spring. The hot water flows from the heater through the outlet pipe C, Fig. 2, and the bore g in the lower casing part G<SP>1</SP> of the gas supply valve E to the bore g<SP>1</SP> of an adapter F 1 . The valve E is controlled by the double diaphragm assembly H which is described in Specification 849,317 and is clamped between casing parts E<SP>1</SP>, G<SP>1</SP>. The valve is biased to a closed position by a light spring F. As the hot water flows from the heater through the restriction g<SP>2</SP> between the bores g, g<SP>1</SP> there is created a zone of reduced pressure, which zone is connected by a bore g<SP>3</SP> to the diaphragm chamber G<SP>2</SP> so that the diaphragm assembly flexes downwardly to open the gas supply valve E. When the temperature of the outlet water reaches a predetermined value steam or water vapour enters the chamber G<SP>2</SP> and the resulting increase in pressure allows the spring F to raise the diaphragm assembly and close the valve E.

The relay 13 is switched from its normal to emergency position by a first timing relay 19 in the event of interruption of incoming pulses from line 9A whereby to connect the panel to receive synchronizing signals from a reserve pulse generator at the other end of the transmission line 9B and which synchronizes the stations which have been isolated from the main pulse generator. When the cause of interruption is rectified the reserve generator is temporarily disconnected either locally or by remote control. Repeater relays 15, 17 become de-energized, being normally energized for the duration of each pulse from the reserve generator, to charge a capacitor 42 which maintains a coil 20B of a second a timing relay 20 energized. Thereby coil 20B is de-energized and contacts 20A open de-energizing the reversing relay coil 13A so that the reversing relay 13 consequently returns to normal operation, whereby a capacitor 41 is recharged energizing the timing relay coil 19B the contacts 19A of which open. Relay 20 returns to normal or short time after 19 and 13 whereupon synchronizing pulses can again be received from the main pulse generator. The procedure described above is simultaneously repeated in all the other repeater panels, so that the entire section of line returns to normal operation.

Title: Fly removing means for air jat weaving loom
IPC: D03D47/30
Filed: 1977-09-23
Abstract: In a loom with air-jet insertion, a weft-yarn holding device (12) possesses a fixed and movable holding part (34) which can be brought together in order to grasp the weft yarn (38). Guided slideably in a bore (30) of the fixed holding part is a tappet (32) which, at one end projecting beyond the fixed holding part, carries the movable holding part. An actuating device (14) serves for the axial displacement of the tappet and for the alternate grasping and release of the weft yarn. A yarn-flock removal device (16) with an air passage (64, 66, 68) on the weft-yarn holding device opens out at one end into the interspace between the movable and the fixed holding part and at the other end is connected to an air pump. When the holding parts are separated from one another by the control of the actuating device, an air stream flows through this interspace and removes yarn flocks and other impurities from this interspace between the holding parts. <IMAGE>
