IPC: G03B17/26
Filed: 1923-05-03
Abstract: 217,716. Enemaerke, R. J. May 3, 1923. Dark-slides.- A darkslide comprises a frame 1 and a shutter-slide 4, the rear part 2 of the frame having a flexible extension 3 the end of which is attached to the rear part of the slide 4. The dark-slide may be constructed of light-proof paper, cardboard, or similar material which is not affected by the developing liquid. The extension 3, which may be made of thin light-proof paper of the same width as the frame 1, limits the extent to which the slide 4 may be withdrawn and prevents entry of light. A frame 10 may be provided between the slide 4 and the plate &c. 5, and may have an upper extension 11 to keep out light. The lower edge 6 of the slide 4 may be concave.

A third regulating valve is operated by a governor on the turbine. The speed-changing gearing comprises pinions on slidable shafts k, l, Fig. 4, the ends of which are connected by cables r to plates r<1>, r<2> coacting with plates q<3> on levers g, so that the racks cannot be moved into mesh with their pinions if the gear shafts are incorrectly positioned. On the sides adjoining the sea, the plant is provided with inclined steel plates b<2>.

Title: Barometric altitude-responsive rate control mechanism
IPC: G05D1/06
Filed: 1955-04-26
Abstract: 778,462. Electric indicating systems. BENDIX AVIATION CORPORATION. April 26, 1955 [May 20, 1954], No. 12032/55. Class 40 (1). A pressure-responsive electric control device responsive to rate of change of altitude comprises a base 10, apertured at 13 to accommodate a coil assembly holder 14 which has an attachment flange 14<SP>1</SP> and an upstanding portion 38 threaded to receive a nut 37 so that the inner sleeve 15 may be positioned vertically by a spring 17 by adjustment of the nut 37. The sleeve 15 supports a transformer coil form 20 containing a primary winding 21 and a pair of secondary windings 22, 23. An armature 25 is mounted on a shaft 26 which at its upper end has a pivotal connection with an adjustable balance weight 40 and at its lower end is secured to the upper diaphragm 27<SP>1</SP> of a capsule 27. The lower diaphragm 27<SP>11</SP> is secured by an attachment 35 to a plate 30 and it is apertured and connected by a conduit 59 to a static pressure line 56. The whole is enclosed in a closed container (not shown) and the junction between line 56 and conduit 59 has a further restricted connection to a pipe 51 (Fig. 2, not shown), enclosed within and communicating with the interior of the container for the purpose of reducing turbulence in the air at said junction and to maintain a pressure difference between the interior and exterior of the capsule under variations of external pressure. The winding 21 is connected to an A.C. supply through a choke coil 69 to establish the proper phase angle between the voltage across the primary and the supply voltage. Thus, as the result of ambient pressure changes, upward or downward movement of armature 25 will increase the signal voltage developed across coils 22 or 23 respectively to produce appropriate rotation of a reversible servomotor.

Title: Improvements in or relating to vehicles for transporting refuse
Inventor: TAPP ERNEST THOMAS JAMES
IPC: B65F3/28
Filed: 1960-04-08
Abstract: 967,172. Discharging refuse vehicles. WALKERS & COUNTY CARS Ltd. April 7, 1961 [April 8, 1960], No. 12597/60. Heading B8E. A piston 18, Fig. 1, for emptying a refuse vehicle through a rear opening, e.g. as described in Specification 910,159, is prevented from tilting either by a supplementary portion extending axially therefrom and engaging a guiding surface on the vehicle body, or by a second piston-like member 27, Fig. 4, which remains at the closed end of the vehicle body until the piston 18 has moved a predetermined distance and then moves with it. As described, the piston 18 has a half-cylindrical extension 14, Fig. 1, and is moved by a telescopic ram 20. An I-section guide rail 22 which is engaged by anti-friction rollers or blocks in the piston prevents the latter rotating. Alternatively, an arcuate shoe 25 attached to the piston by a bracket 26 and similarly guided by a guide rail 22 may prevent tilting of the piston. In a third embodiment the piston-like member 27, Fig. 4, is held against the closed end of the vehicle body by a spring until a shoulder or the piston-rod, which may be a jamming fit in the hole through which the rod passes, moves the member 27 with the piston 18. Alternatively, the member 27 may be held against the closed end of the vehicle body 31, Fig. 6, by spring-loaded plungers 37 which engage a dished plate 39. The plungers are withdrawn by springs 38 from the plate 39 when a groove 35 in the piston-rod 29 coincides with them. At the same time a shoulder 32 abuts the member 27 and moves it with the piston 18. The vehicle is loaded with compressed refuse as described in Specification 910,158 or a charging opening may be provided in the top of the body to the rear of the piston when it is at the forward limit of its travel.

Abstract: 624,754. Heating water. HAUSSAUER, L. P. May 9, 1947, No. 12611. [Class 64(i)] In a water heater of the kind comprising a hot water storage tank 1 having a cold water inlet 9 and a hot water outlet at the top of the tank including an expansion pipe (not shown), and in which is mounted a calorifier unit 5 connected directly to a fired boiler, the calorifier unit 5 is in the form of a cylindrical annular jacket being supported within the tank by flow and return pipes 6 and 7 which lead to and from the boiler. The calorifier filling means comprise an inlet pipe 10 projecting vertically downwards from the bottom of the calorifier unit and a U-shaped pipe 11 constituting a combined vent and air trap with the bight projecting above the unit, one end of the pipe communicating with the annular jacket at 13 and the other end 14 communicating with the tank space, the arrangement being such that as the storage tank is filled, water flows into the calorifier system through the tube 10, air being displaced through the U-tube 11, and when a certain level determined by the position of the U-tube is reached, the inflow of water to the calorifier unit is cut off due to the air trap formed by the bight of the U-tube. The calorifier unit may be additionally supported by soldering or otherwise securing it to the wall of the storage tank and the flow and return pipes may be soldered together at their point of contact 15. The storage tank may be surrounded by an insulating jacket 2 the base 3 of which is provided with an insulating' ring 4 on which the tank is seated. One or more electric immersion heaters 16 may be disposed within the storage tank to provide alternative heating means for the water therein. According to the Provisional Specification the calorifier unit may take the form of a coiled tube.

Granules from a hopper 15 are distributed on a conveyer 16 by a conveyer 21, heated by infra-red heaters 17 and compressed into a sheet by rollers 19, 20. A carpet is fed from a roll 4 by driven rollers 9 and 13 and a tensioning and guiding system 12, and laminated with the backing between rollers 19 and 22. After passing through heater 24 the backing is embossed by rollers 25, 26 and cooled by air blowers 29, 30. The backed carpet passes through a loop control 32 before measuring and cutting by a device 33, or is rolled up by driven rollers 35, 36. Heated granules may also be applied to a paper carrier, compressed, and a second layer applied before lamination to a carpet, which may then be cut up into carpet tiles. Granules may be attached by casting them on the back of the carpet with adhesive instead of heating the granules.
