Title: Improvements in devices for thawing deep-frozen substances
IPC: A23B7/045
Filed: 1959-10-14
Abstract: 921,748. Thawing and heating frozen food &c. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 14, 1959 [Oct. 16, 1958], No. 34839/59. Class 49. [Also in Groups XI and XL (c)] Apparatus for thawing deepfrozen food and other substances in a thawing chamber using hot air and high-frequency energy, has hollow waveguide supply channels 16, Fig. 2, for the supply of high-frequency energy to a plurality of positions 4 in the chamber, at or near which positions thawing of portions of deep-frozen food &c. is to be effected by way of a first series of slots 11, Fig. 4, provided in the walls of the supply channels 16 at the positions, and means for circulating hot air through a second series of slots so positioned along the waveguide supply channels as to prevent the escape of highfrequency energy; these latter slots are preferably vertical slots 9, Fig. 5 (not shown) in the side walls 10, Fig. 1, of the chamber. A rectangular hollow waveguide 7, Fig. 1, passing along the rear wall of the chamber feeds highfrequency energy from a magnetron operating e.g. at a wavelength of 12.5 cms., through slots 6 and intermediate couplings 6 to the supply channels 16. In order to avoid undesirably high energy concentrations at the slots 11 in the channels 16, the food &c. portions may be positioned in dishes on rails 12, Fig. 6, so that a substantially constant spacing is maintained. For uniform irradiation the width of the slots 11 may be 4 mm., but by the choice of the place and size of the slots the food &c. may be irradiated strongly from below whilst the top is subjected to a weaker irradiation. Reference has been directed by the Comptroller to Specification 888,518.

Title: Improvements in or relating to vacuum brake apparatus for motor road vehicles, tractors and trailers
IPC: B60T15/20
Filed: 1929-11-14
Abstract: 343,148. Fluid-pressure brakes. CONSOLIDATED BRAKE & ENGINEERING CO., Ltd. and PALMER, B. W., Windsor Works, Slough. Nov. 14, 1929, No. 34865. [Class 103 (i).] In vacuum brake apparatus for tractor and trailer vehicles comprising a vacuum reservoir and an emergency valve, whereby the brakes of the trailer will be applied if it breaks away from the tractor the emergency valve comprises chambers 36, 37, 38, Fig. 2, separated by diaphragms, and connected respectively to the exhauster, the atmosphere and an auxiliary vacuum reservoir. A chamber 39 is connected to the brake cylinders and contains valves 42, 43 coupled to the stem connecting the diaphragms and controlling communication between chambers 38, 39 and the chamber 39 and a port 23 leading to the driver's valve. A passage 50, 46 contains a non-return valve 48. The tractor brakes are applied if the trailer breaks away. The main reservoir 8, Fig. 1, is evacuated from the induction pipe 5 of the vehicle engine. The chambers 36 of the emergency valves 10a, 10b are also evacuated through pipes 11, 14, 17 and also each of the reservoirs 24, 25 through the ball valves 4, 8, Fig. 2, chamber 38 and connection 27. Chamber 37 is connected to atmosphere, and in view of the relative sizes of the diaphragms 40, 40a the valve stem 41 is raised to close the valve 42, and open the valve 43. The brakes are normally applied by passage of fluid from the main reservoir by means of the driver's valve 9, pipe 18, the normally open valve 43 in the emergency valve 10a, and pipe 29 to the tractor brake cylinders 1, 2 and by pipes 20, 23, emergency valve 10b and pipe 33 to the trailer brake cylinders 43, 4. If the trailer breaks away air is admitted to the emergency valve chambers 36 and the emergency valves move to close the valves 43 and to open the valves 42 and thus connect the emergency reservoirs 24, 25 to the brake cylinders. The trailer brakes may be released by a cock 35. Shut-off cocks 14a, 20 are provided on the tractor. Tractor braking may be delayed by a check valve in the pipe 26 to the port 27 on this part, may be restricted or a valve in the coupling 16 throttles the air passage when the coupling parts. The main reservoir may be omitted. The valve controlled communication between the emergency reservoir and the exhauster might be arranged otherwise than through the emergency valves. Specification 320,739, [Class 103 (i), Brakes &c.], is referred to.

Title: Improvements in or relating to photographic cameras
IPC: G03B19/02
Filed: 1922-12-22
Abstract: 213,001. Laws, F. C. V., and Stringer, H. B. Dec. 22, 1922. Cameras for taking a series of photographs on one plate; surveying and aeronautical apparatus. -A photographic camera is constructed with two or more lenses having one or more inclined mirrors, reflecting prisms, &c. for taking two or more photographs of objects situated in different directions, and a shutter arrangement or arrangements for providing simultaneous exposure from all the view points. The mirrors &c. may be arranged in front of or behind the lenses according as these are directed in the same or in different directions. In one form, Figs. 1 and 3, for taking five photographs simultaneously on a single plate channels formed by screens 11 extend between each lens 7 and the plate. An inclined mirror 12 which may be of stainless steel is pivotally attached to a turntable sleeve 16 in front of each of the outer lenses so that both its inclination and direction can be adjusted. The lenses are provided with between-lens shutters which are set and released simultaneously. The shutter setting levers 23 of the outer lenses are actuated by spring controlled levers 22 mounted on links 19 pivotally connected by bell-crank levers 18 pivoted on pillars 17 on the lens-supporting diaphragm 9. The links 19 are moved by a Bowden wire 26 attached to one of the links, against the tension of a spring 28, and their return movement can be altered by means of an adjustable stop 29. An arm 30 extending from one of the links 19 actuates the, shutter setting lever 23 of the central lens. The shutters are simultaneously released by moving, by means of a Bowden or like wire 42, a wedge 37, controlled bv a spring 38, up against a pin 41 attached to the main release lever 35, five adjustable screws 34, Fig. 4, on which are then pressed into engagement with the plungers 33 connected to the free ends of Bowden wires 31 connected to the shutters. Other forms of shutter for use behind the lens and in front of the plate, such as that described in Specification 213,018 may be employed.

Title: Concrete finishing method and machine
IPC: B28B11/08
Filed: 1973-07-25
Abstract: 1395303 Moulding ribs on concrete panels W D PATON and T W STEENSON 25 July 1973 35495/73 Heading B5A [Also in Division F2] The surface of a concrete panel 14 (Fig. 1) is ribbed by moving over the surface a plurality of discs supported at intervals along a shaft 22, the discs being rotated in a direction 48 (Fig. 3) such that their rotational movement relative to the concrete at their lower extremities is in the same direction as the movement 50 due to their advance across the concrete. The discs drive a furrow 52 of wet concrete in front of them, and cause aggregate to move to the tops of the ribs, probably by suction. As described, concrete comprising a coarse aggregate, e.g. small pieces of stone having rounded corners, and a facing mix are cast in a mould having adjustableheight mould sides 10, guards 42 to keep in excess concrete, and steel transverse and longitudinal partitions (not illustrated). A wheeled carriage 16 runs on tracks 20 in either direction propelled by a variable speed motor 29. At each end of the carriage is supported a shaft 22 carrying discs, the shafts being rotated by a motor 28 and being adjustable in height by hand cranks 26. The first run of the carriage 16 levels the concrete. On the second run, the leading set of discs is rotated to form the ribs and move the aggregate to the rib tops, while the trailing disc set is lower than and rotates in opposition to the first set, to press in the formed ribs. An operator seated on the carriage adjusts the speed of disc rotation continuously as the concrete slump varies. Sand blasting or acid etching removes the film of cement covering the aggregate in the rib tops. The disc faces are straight or tapered and their spacing and penetration are adjusted to control the suction set up; variable disc widths and spacing can be used along each shaft 22.
