Filed: 1928-01-13
Abstract: 309,882. Dunlop Rubber Co., Ltd., Randles, J. T. T., Willshaw, H., and Smith, H. Jan. 13,1928. Discharging and feeding devices for endless-chain conveyers and elevators with articles hung on hooks.- Goods transported by an endless chain conveyer to the various floors 12 of a store are removed therefrom by devices 'actuated automatically and controlled by keys placed upon the chains by an attendant previous to the imposition of the goods, a different key being provided for each removing device. The conveyer comprises parallel chains 1, 2 bridged by a series of rods 3 carrying hooks 4 which engage the articles to be transported. Each removing device comprises a bar 55 and a shoot of the gravity roller-way type composed of two members 16, 17 pivoted at 18, 19, respectively, which when inoperative hang down but are brought into alignment when operative. The bar 55 is moved backwards and forwards in accordance with the movement of the member 16, and when the members 16, 17 are in alignment, it is in the path of an extension 50 of each hook 4. In this position. when an extension 50 strikes against the bar 55, the hook is tilted and the article deposited on the shoot.. The members 16, 17 are moved into and retained in either position by the fluid-pressure-actuated pistons 29, 30 of cylinders 26, 25. Fluid is admitted to the cylinders by pipes 36 controlled by a rotary valve, the stem 40 of which has a number of projections 41, 42 of different shapes arranged in two series. The projections of one series alternate with those of the other, and one series is arranged to actuate the valve to effect the alignment of the shoots while the other is arranged to put them out of action. The projections of each valve are of a different setting ,and are arranged-so that the projection for dosing any specific removing device can be actuated only by its particular key while each key operates all the valves to put the removing devices out of action. The keys 60 have projections 63 for engaging the projections on the valves, and pegs 61 for insertion in the chain links. Tilting of the hooks at the feeding point is prevented by a guide 78 or by an endless belt. An indicator 65 is provided at the feeding point and subindicators 66 at each floor. The keys 60 are placed on springs 70 on the switchboard of the indicator 65, the arrangement being such that when a key is removed, its spring will make contact with a terminal 71 and the corresponding sub-indicator will be actuated.

Title: Improvements in or relating to a projector for kinematographic films, adapted for use as a pre-viewing apparatus
IPC: G03B41/14
Filed: 1953-01-15
Abstract: 726,061. Kinematograph apparatus. PAILLARD SOC. ANON. Jan. 15, 1953 [Feb. 12, 1952], No. 1190/53. Classes 97 (1) and 98 (1). [Also in Groups XXXV and XL (b)] In a projector for editing purposes the film is illuminated by flashes from a discharge lamp synchronized either with alternating current mains or with the passage of successive film frames, the latter by utilizing impulses derived photoelectrically or electromagnetically from a disc coupled to a friction driven sprocket. The mains-controlled illumination provides prolonged projection of a single frame for examination or photographic copying. As shown, Fig. 1, a spool 6 is rotated by a hand-crank, not shown, to draw film from a spool 5, past a gate 8, over rollers 7, 10 and a sprocket 9. An image is projected by an objective 12 on to a screen 3 hinged above a glass plate 15 on to which photographic paper may be clamped for enlarging. The screen assembly is adjustable on a column 2. A discharge lamp in the housing 11 is fed from a circuit shown in Fig. 2, S being the lamp. The voltage supplied from a source D to a condenser C through the resistance R does not strike the lamp until a pulse is applied to the electrode E. This pulse is derived from an induction coil B through the primary of which is discharged, by closing a switch I, a condenser C<SP>1</SP> charged through a resistance R<SP>1</SP>. The switch I is formed by a thermionic valve fed from an amplifier to which is applied a signal either from alternating current mains or with pulses generated in synchronism with the film feed by the sprocket 9. For this purpose a non-magnetic disc on the sprocket shaft, carrying radial spokes of magnetic material, passes between the poles of a magnet on which is wound a coil in which impulses are generated. A switch is provided to reverse the polarity of the impulses according to the direction of film feed, to maintain the projected picture in the same position for either direction. An alternative device for generating the impulses comprises a radially slotted disc on the sprocket shaft, passing between a lamp and a photoelectric cell.

Title: Improvements in or relating to steam generators for extracting heat from the exhaust gases of internal combustion engines
Inventor: WAGNER HAROLD
IPC: F22B1/18
Filed: 1965-01-12
Abstract: 1,076,541. Waste heat steam generators. E. GREEN & SON Ltd. Dec. 15, 1965 [Jan. 12, 1965], No. 1420/65. Heading F4A. Feed water from pump 9, pre-heated by heat exchange with boiler water in heat exchanger 6, is fed into the drum 4 of a water tube boiler heated by the exhaust gases of an internalcombustion engine. From the drum 4 the water is circulated by pump 5, in two streams, one stream flowing through steam generating section 2 and back to the drum 4 through line 8, and the other, after heating the feed water in heat exchanger 6, flowing through economizer 3 and back to the drum 4 through line 7. A superheater 1 is provided. The boiler water flow through heater 6 is thermostatically regulated by valve 10 to maintain water entering economizer 3 above a minimum temperature so preventing acid condensation. Variations in steam demand are met by supplying some of the water to the economizer 3 through valve 11 so by-passing the feed water heater 6. This increases the temperature of the water entering the economizer and so reduces the heat pick-up from the exhaust gases. The valve 11 is controlled by the steam pressure in the drum 4. The steam generating section may be divided into four valve-controlled sections in parallel flow (Fig. 2, not shown), to enable one or more of the sections to be cut-off to meet a reduced steam demand. Auxiliary heating means may be provided.

IPC: H01Q1/28
Filed: 1950-01-21
Abstract: 672,034. Aerials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 18, 1951 [Jan. 21, 1950], No. 1656/50. Class 40 (vii). An aerial system comprises a conductive surface on which is mounted a conductive fin electrically united with the surface, the dimensions of the fin are one quarter to one half a wavelength deep at a point half way along its length and one or two wavelengths in maximum peripheral measurement away from the surface at the frequency of operation, a notch is disposed in the fin substantially half-way along its length and a transmission line connected across the notch for coupling the fin to a transducer. The aerial is of particular use on aircraft, the fin being arranged to lie along the direction of flight and the surface being the aircraft skin. Preferably the fin is mounted at right angles to the surface and in its simplest form, Fig. 1 (not shown), consists of two flat laminµ a quarterwavelength square attached to the conductive surface in the same plane so that there is a gap or notch between them. A coaxial feeder brought through a hole in the surface adjacent to one of the laminae has its outer connected to the one lamina and its inner conductor to the other. The position of attachment of the feeder along the length of the notch if chosen to match the aerial to the feeder and the width of the notch is made small compared with the operating wavelength and preferably such that the characteristic impedance of the notch regarded as a transmission line approximates to the radiation resistance of the aerial. The simple laminµ may be replaced by streamlined and hollow members such as a<SP>1</SP> and b<SP>1</SP> (Fig. 2) concealing and protecting the transmission line d. Two parasitic fins el and e<SP>2</SP>, tuned by notches c<SP>1</SP> and c<SP>2</SP>, may be disposed parallel to the aerial and so dimensioned that the currents in them lead or lag those in the aerial as required. Each parasitic fin may be regarded as approximately equivalent to a dipole coincident with the edge of the fin remote from the surface. In an end-on array a simple aerial system a2, b<SP>2</SP> fed across the notch c is extended by additional portions a<SP>3</SP> and b<SP>3</SP> of about the same dimensions as, and respectively coupled by notches c<SP>3</SP> and c<SP>4</SP> to, a2 and b<SP>2</SP>.
