Title: A Method of Running Pneumatic Despatch Systems, and Pneumatic Despatch Systems for Carrying Out the Method
Inventor: LARSEN ERIK VALDEMAR THOMAS KO
IPC: B65G51/20
Filed: 1969-04-01
Abstract: 1,197,422. Pneumatic conveyers. E. V. T. K. LARSEN. 1 April, 1969 [1 April, 1968], No. 17112/69. Heading B8A. In a pneumatic despatch system having terminal and intermediate stations 3, 4 and 2, pressurized air is supplied to both ends of the transportation tube 1 at points beyond the terminal stations 3, 4 and the selected receiving station is opened to atmosphere so that a despatch cartridge 10 arriving at that station seals off the system air to atmosphere whereupon the cartridge is braked by the balanced air pressure at each end thereof. Each station comprises a box housing into and from which extends the tube 1, a valve 8 for exhausting the box to atmosphere, and a magazine of open sided tube pieces 6 which are rotatable within the box to both align a piece 6 with the tube 1 for receiving the cartridge and thereafter align that piece with a receiving box for the cartridge. The latter rotation of the magazine may be automatically controlled by the arrival of a cartridge in the piece 6. With the valve 8 closed to atmosphere and with a tube piece 6 in line with the tube 1, the station will act as a through station. In a further embodinent, the box housing is dispensed with and tube pieces without openings are provided in the magazine to form a through station when required.

Title: Improvements in and relating to machines for spreading cream, or laying coatings on wafers or other surfaces
IPC: A21C15/00
Filed: 1929-06-04
Abstract: 334,577. Macfarlane, R. F., and Baker Perkins, Ltd. June 4, 1929. Coating bakers' &c. goods. - In a machine for depositing or laying coatings upon surfaces, and more particularly for spreading cream, icing or the like on biscuits or the like, the cream or the like is applied by an endless band or surface to biscuits carried past the coating position on a conveyer, and resilient means press the biscuits on to the conveyer in the vicinity of the cream application. The goods are carried on the conveyer 3 beneath the roller 26 over which the coating band 28 is trained. The band 28 travels, at the coating position, in the opposite linear direction to the conveyer 3. The cream is fed from a hopper 31 into an open-bottomed box having two sides joined by a front wall 29 which is adjustable vertically or has a sliding shutter for regulation of the thickness of cream applied to the band 28. The back of the box is open for the return of the cream thereto, outlying cream being directed into the box by plates or pads 32. The width of the cream applied is regulated by side boards 34 adjustable by rack and pinion mechanism. The box contains a rotary stirrer 36 which is detachably clutched to a driving shaft. The band 28 is tensioned by screws 25 which position the pulley 27. The cream on the band may be heated by a heater 41, and, in addition, water cooling-means may be provided. The goods are raised up to the coating band by a roller 12 which is vertically adjustable by cam means associated with the handle 18; and lifts the conveyer 3. Resilient fingers 42 engage the goods as they pass the coating position to increase the friction with the conveyer 3 and ensure that the goods will pass the roller 26. A smoother 44 is pivotally mounted on a rod vertically adjustable in the bearings of a non-adjustable roller 11 which assists in supporting the upper run of the conveyer 3. The smoother 44 is pressed down on the coated goods by a weighted arm 48. Resilient fingers 52, similar to the fingers 42, keeps the goods down on the conveyer 3. If sandwich biscuits are to be made, more than one coating apron is provided, cover biscuits being applied manually or automatically. The conveyer 3 is carried in a frame 6 pivoted on the shaft of the roller 4 and positioned by adjustable screws 9.

Abstract: 649,638. Bending tubes. HUET, A., and COMPAGNIE DES SURCHAUFFEURS. July 1, 1949, No. 17459. Convention date, July 2, 1948. [Classes 83 (ii) and 83 (iv)]  In a method of forming U bends of small radius in metal tubes, a previously formed tube A with a U bend of large radius is shaped by two relatively slidable die blocks 15, 16 over a grooved former 14 conforming to the inner surface of the required bend, the temperature of the tube wall at the inside of the bend being maintained appreciably higher than that of the wall on the outside of the bend. The former 14 is mounted on a bolt 12 between two plates 10, 11 maintained by spacers at a distance apart equal to the outer diameter of the tube and having grooves 20 for slidably carrying the die blocks 15, 16 which are shaped to conform to the outer radius of the bend. One of the blocks only need be slidable in which case the former 14 is also made slidable between the plates. Access for heating the tubes on the inside of the bend by oxyacetylene flame or the like is provided by cut-aways 18, 19 in the former 14 and plates 10, 11 respectively.

Upper inner forms 30, detachably secured together, are supported upon side portions 35 of the lower inner form 18 which advances as the casting operation proceeds leaving the upper inner forms 30 in position in the conduit, from which they are subsequently removed when the concrete has set. The upper inner forms 30 extend through the barrier 16a which is provided with sealing means 57 to prevent leakage of cement. The lower inner form 18 is braced by cross members 37, 38, and those upper inner forms which are left unsupported by the form 1 as it advances, are braced by cross members 44. The inner form 18 is provided with an elevated portion 20 and an inclined spreader 19. A vibrator 60 is provided on the lower inner form and other vibrations 61, Fig. 5 (not shown) are provided on the hopper.

Abstract: 1,011,769. Amplitude modulation. BUDAVOX BUDAPESTI HIRADASTECHNIKAI VALLALAT. May 9, 1962 [May 9, 19611, No. 17877/62. Heading H3R. In an arrangement for amplitude modulating a microwave generator 3 with a phase modulated pulse train from source 1, the uncertainty of the time of commencement of the amplitude modulated pulse due to noise in the circuit is overcome by pre-exciting the grid cavity of the generator with a harmonic of the pulse train. The modulating pulses in addition to being applied to the anode of the microwave triode 3 are also applied via biasing circuits 5 and 6 to a silicon diode 2. Each pulse produces a large number of harmonics one of which falls within the resonant frequency range of the grid cavity and develops a pre-exciting current therein. The diode circuit is arranged to respond to each modulating pulse before the oscillator hence oscillations build up on the preexciting current at a predetermined time after the pulse commencement.

Filed: 1923-07-11
Abstract: 225,898. Withers, J. S., (Deutsche Evaporator-Akt.-Ges.). July 11, 1923. Feed-water, heating.-To. prevent overheating in the economizer 21, Fig. 2, when the pressure operated feed valve 3 is closed, a valve 23 in a by-pass may be so operated by a thermostatic device 22 that a flow of water is maintained between the economizer and the boiler. A permanent small flow is maintained through a valve 25. In a modification, a constant flow of water is maintained through the economizer, excess water being received when the boiler feed requirements are small by an equalizing chamber from which it is subsequently withdrawn when the boiler feed requirements are large. A thermostat increases the flow of water through the economizer when the water temperature rises and decreases it when the water temperature falls. The flow is also controlled by a float in the equalizing chamber. Water overflows from the equalizing chamber back to the feed tank. In a further modification, the equalizing chamber 39, Fig. 4, is connected to the boiler steam and water spaces and serves as a storage chamber. When the pressure operated valve 3 is fully open the feed pump 36 takes water from the lower part of the chamber 39 in addition to that supplied through the economizer 21. At the same time hot water flows from the boiler through a pipe 28 into the upper part of the chamber. When the valve 3 is closed, hot water is forced into the boiler through the pipe 28 by the water entering the lower part of the chamber.
