Patent GB-389725-A (GB)
Title: Improvements in or relating to fire alarm street boxes or like signalling apparatus
IPC: G08B25/12
Filed: 1932-08-12
Abstract: 389,725. Fire-alarm systems. STANDARD TELEPHONES & CABLES, Ltd. and BATES, E. F., Connaught House, Aldwych, London. Aug. 12, 1932, No. 22575. [Class 40 (i).] The pull handle P of a fire-alarm or like signal box co-operates, through the intermediary of a pivoted lever O carrying a latch T, with a pivoted lever S which is adapted to operate the starting lever F of the signal transmitter. When the handle P is pulled the latch T operates lever S to start the transmitter, but after predetermined movement the latch becomes disengaged from the lever S to allow restoration of the levers F, S to normal after the code signal is sent in the event that the handle P is held operated. Thus the arrangement ensures that a normal code signal is transmitted irrespective of whether the pull handle is allowed to restore immediately after operation or is held operated. The pull handle is associated with a glass plate X. In a modification, the operating handle is pivoted on the door of the box and carries a lever adapted to co-operate with a second pivoted lever associated with the starting lever. The arrangement is such that after a predetermined rotation the first lever becomes disengaged from the second lever to permit restoration of the second lever independently of the handle.

Title: Electric clockwork apparatus and method of synchronising same
IPC: G04C11/08
Filed: 1937-01-06
Abstract: 488,065. Electric clocks. COMPAGNIE INDUSTRIELLE DE MECANIQUE-HORLOGERE. Jan.. 6, 1937, No. 22648. Convention date, Jan. 6, 1936. Divided out of 485,026. [Class 139] Method and apparatus for operating a synchronous-motor clock having an auxiliary reserve spring drive which is kept energized by the motor, in which the speed of the train to the hands driven by the spring is voluntarily increased while the motor is running (by parts 38, 9<1>) and the movement of the spring drive is mechanically braked to bring the mean speed of the train to a value proportional to the current frequency, the spring regaining its normal speed controlled by a balance when the motor is stopped. Between the motor 2 and the wheels driving the hands 1 are two wheels 32, 34, loose on shaft 33 and connected by a spring 35 ; wheel 32 being driven by the motor 2 and wheel 34 by the spring 3. Coacting with the hairspring 9<1> is a finger 38 on a lever 36 which is rocked clockwise about its pivot 37 by a magnet 40 which is energized by the motor current, so that whilst the motor is running the finger 38 presses against the hairspring to cause the escapement to increase in speed. The supersynchronous speed at which wheel 34 is driven by spring 3 exceeds the speed of wheel 32 and since the motor 2 is more powerful than spring 3, the effect is to retard the wheels driven from spring 3 to synchronous speed. When current fails, the motor 2 is driven by spring 3 and finger 38 releases the hairspring 91.

Title: Improvements in or relating to web reel changing mechanism
IPC: B65H19/18
Filed: 1931-08-12
Abstract: 387,017. Feeding webs. HOE & CO., Ltd., R., 109, Borough Road, London.- (Hoe & Co., Inc., R. ; 138th Street, New York, U.S.A.) Aug. 12, 1931, No. 22774. [Class 100 (i).] In a web-changing mechanism the running web roll R and the spare web roll S are supported by bent arms 4, 5. A lever 14 is pivoted to the bent arms and carries at its end further bent arms 34, 35 upon which rolls 36, 37 are mounted and connected by gearing to handwheels 50, 49 respectively. The rolls 36, 37 operate as speeding-up devices, or pressure devices to join the running web to the spare roll according to which roll they are turned, the running web passing between them. The lever 14 is oscillated by treadles 18, 19 and when joining, the web is slowed down and the lever 14 turned towards the spare web roll until one roll 36 or 37 comes in contact with it when it is rotated by the hand-wheel and the lever 14 further depressed until the other roll brings the web into contact with the pasted surface of the spare web roll. The spring 47 causes the pressure of the rolls 36, 37 upon the web roll.
Patent GB-776077-A (GB)
Title: Improvements in and relating to reinforced concrete containers and the like
IPC: E04H7/26
Filed: 1954-08-05
Abstract: 776,077. Reinforced concrete. WALLER, J. H. De W. Nov. 4. 1955 (Aug. 5. 1954], No. 22806/54. Class 20(4) [Also in Groups XXVIII and XXIX] A concrete container, e.g. silo, bunker, tank, hopper, chimney or pipe, is made by providing a reinforcement assembly of the required shape, tensioning the assembly by the internal pressure exerted through a lining by a liquid, gas, or granular material, and embedding the reinforcement in concrete applied exteriorly. The reinforcement may consist of vertical rods 1 to which circular rods 2 are welded, and it is lined at 3 with a flexible material, e.g. woven material, metal sheet or expanded metal, which lining is filled, e.g., with granular material. The horizontal pressure of the material on the reinforcement tensions the latter, and the tension is maintained until the concrete 4 applied, e.g. with a cement gun, has set, afterwhich the granular material is removed. If woven material or wire mesh is used for the lining, it may remain in place, an interior layer 5 of concrete being applied over it. If the loading is to be effected by a liquid, e.g., oil or water, the lining is of impervious material, e.g. tarpaulin. If a pipe is being made, the reinforcement is tensed by a removable bag supplied with compressed air or liquid, e.g., water from a main. The use of pervious linings with a granular filling produces compression in the vertical members of the reinforcement assembly. To avoid this, a rigid lining consisting of boards 6, or corrugated sheets 7, and, if desired, an impermeable lining in addition, may be used. In this case, the pressure on the reinforcement may be increased by using members 6 or 7 of enhanced height. The pressure on the reinforcement may be applied by vertical concrete members 10, arranged side by side on a concrete base 8, the joints between the members 10 being sealed by adhesive strips. The reinforcement 13 may consist of a steel rope wound helically or in separate rings around the members 10. The applied concrete 15 effects a seal with the base 8 by filling the space inside a ring 16, and reinforcements 9 in the base project at 12 into the applied concrete to key it to the base. The inside of the tank may be treated or lined in any desired manner. In a modification, the tank has a raised circular step outside the applied concrete, the space between the step and the concrete being subsequently caulked to prevent leakage.

Title: New or improved feeding mechanism for cylindrical articles
IPC: B65G47/26
Filed: 1945-09-05
Abstract: 598,619. Metal heating furnaces. BEESTON, W. G. Sept. 5, 1945, No. 22911. [Class 51 (ii)] [Also in Group XXX] A conveyer for feeding cylindrical articles such as billets down an inclined track in a heattreatment furnace comprises a plurality of spaced pivoted levers each having two arms of which the upper edges are at an obtuse angle to each other, each lever being so arranged that the arm directed towards the upper end of the track is held raised to arrest an article so long as the next article bears on the other arm but drops under gravity into alignment with the track when the lever is free, and the free end of the first arm then engages the free end of the other arm of the next lever above to hold that arm in alignment with the track until the arm of the first lever which is directed towards the lower end of the track is positively depressed by an article moving down the track. Figs. 1, 3, 4 show an embodiment wherein billets f, f<1>.....f<6> are supported within the furnace on stop levers e, e<1>..e<6> pivotally mounted at d on inclined track members, the billet f being held by two manually or automatically controlled star wheels g. When these wheels are released for rotation through 90 degrees the billet f passes off the track thereby freeing the lever e which is weighted so that its rear arm moves down to hold the forward arm of the lever e<1> in alignment with the track, Fig. 3, whereby the billet f<1> is released and rolls down to abut the wheel g, Fig. 4. The lever e<1> is now freed and its rear arm moves down to hold the forward arm of the lever e<2> in alignment with the track and release the billet f<2> which rolls down until stopped by the rear arm of lever e. This is repeated with the other billets in succession to the rear end of the track where another billet is fed on to the track to be stopped by the rear arm of the lever e‹. A positive rocking movement of each stop lever to release the next billet above as a billet passes off it, is obtained by mounting a trip member h, Fig. 5, on the pivot of each stop lever. A projection k on this member is engaged by an article passing over the stop lever to rock the trip member so that its projecting finger j engages and positively raises the front arm of the next lever above. The hinged doors m may be controlled by the movement of the stop levers.

Title: Improvements relating to fluid pressure braking apparatus for vehicles
IPC: B60T7/04
Filed: 1930-08-01
Abstract: 360,042. Fluid-pressure and electric brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Farmer, C. C. ; 7008, Thomas Boulevard, Pittsburg, U.S.A.) Aug. 1, 1930, No. 23270. Convention date, Aug. 7, 1929. [Class 103 (i).] A valve device for controlling the fluid-pressure brakes of a vehicle is adapted to be actuated by two parts of the foot of the operator in such a manner that the brakes are applied by the pressure of, for instance, the toe and also by release of the pressure of the heel. The brakes are thus applied in the event of incapacitation of the operator. Electrodynamic brakes may also be applied by the toe member. A lever 4 pivoted at 3 within a casing 2 is provided with a toe piece 5 and carries spring contact pieces 11 for engagement with a contact bar 14. A lever 23 pivoted at 24 is engaged by the lever 4 and engages also a plunger 21 between which and a diaphragm 17 a spring 19 is disposed. A bar 33 rockably supported on the diaphragm engages the stems 36, 41 of exhaust and supply valves 37, 42 for the brake cylinder 47 which is connected to the chamber 38 beneath the diaphragm. A yoke lever 26 pivoted at 24 and embracing the lever 23 also contacts with the valve plunger 21 and is connected to a spring plunger 28 provided with a heel piece 31. Normally the operator depresses the plunger 28 and applies no pressure to the toe pedal 5. The valves 37, 42 are thus opened and closed respectively as shown and the brakes released. If the pedal 5 is depressed the switch 11, 14 is first closed whereby circuits are completed to put the electrodynamic brake into operation by causing the vehicle motors to run as generators. With further depression of the pedal the switch 11, 14 is re-opened to cut out the electric brake and pressure is applied to the bar 33 by the lever 23 and spring 19. The exhaust valve 37 is thus closed and the valve 42 opened to supply compressed air to the brake cylinder 47. When the pressure in the cylinder and chamber 38 is sufficient to overcome the spring 19 the diaphragm moves upwardly and the valve 42 closes. The degree of pressure in the brake cylinder thus corresponds to the amount of compression of the spring. The release of the brake can also be graduated by permitting the pedal to rise. The plunger 21 is also depressed to apply the brakes by the spring 30 acting through the lever 26 if the operator removes his heel from the plunger 28. Further the brakes having been applied by the pedal 5 may, if desired, be held applied by relieving the pressure on the plunger 28 the necessary amount.
