Title: Apparatus for reducing the thickness of metal
IPC: B21B13/18
Filed: 1973-07-17
Abstract: 1374924 Rolling mills IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 17 July 1973 [26 July 1972] 3689/72 Heading B3M A metal strip 25 being fed between the rolls 13 of a pendulum mill is guided and tensioned by rolls 20 and 22, the rolls 20 being thicker at their ends than their centre to prevent the strip from moving laterally. The rolls may be profiled to have thicker ends, or may be deformed into this shape by axial pressure exerted against their ends. The rolls may reduce and taper the strip slightly before it is rolled in the pendulum mill. The mill comprises work rolls 13 and backing rolls 14 carried on oscillatable arms 10 driven by crank-shafts 18. The arms are pivoted at 12 to beams 11 which are movable by screwdowns 19 to vary the roll gap.

Title: Improvements in or relating to combined water heater and air conditioner of the heatpump type
Inventor: RUFF ALONZO WILLIAM
IPC: F24F5/00
Filed: 1953-02-10
Abstract: 724,409. Heat pumps for cooling air and heating liquids in bulk. PATTERSON & ASSOCIATES, Inc., V.C. Feb. 10, 1953, No. 3693/53. Classes 29, 64 (1) and 64 (3). Apparatus for cooling. air and heating water comprises an insulated hot-water tank 10 and a refrigerating system having a sealed motor compressor unit 11 in a recess in the tank to heat the latter, a high pressure gas pipe 15 connected to a vertical pipe 20 within the tank and surrounded by a concentric pipe 19 the top and bottom of which are joined by vertical pipes 21 serving as water heaters and coolers and condensers for the refrigerant, a supercooler 22 for the liquid refrigerant and for preheating the water, an expansion valve 18, an evaporator 13 mounted on the top of the tank and fitted with a variable-speed air-circulating fan 14 and a thermal element 26 responsive to. the temperature of the water to stop the compressor motor at predetermined maximum water temperature. According to the invention, a switch 27 is provided for cutting out the thermal control to allow air cooling even when waterheating is not required, excessive heating of the water being obviated by bleeding off hot water from the tank. The switch 27 may be controlled by a humidostat or thermostat subject to conditions of the air being cooled. For drying the air, the speed of fan 14 is reduced by a switch 28 thus allowing the slower-moving air to be cooled more. Switch 28 may be controlled manually or by a theromostat or humidostat. As shown in Fig. 1, a valve 29 subject to the outlet pressure of the compressor allows water to escape from the tank when the discharge pressure rises due to an increase in condensing temperature. As shown in Fig. 5, the tank 10 has a valve 33 opened by a thermal element 32 when the temperature of the water rises e.g. ten degrees higher than the setting of thermal element 26. The bleeding valve may be located in the main outlet 24 of the tank. A baffle 25 is welded to the pipe 19 to improve stratification of the water in the tank. U.S.A. Specifications, 2,516,093 and 2,516,094 are referred to.

Title: Improvements in or relating to container filling machines
IPC: B65B3/32
Filed: 1968-01-27
Abstract: 1,270,261. Container filling apparatus. ALBRO FILLERS & ENG. CO. Ltd., and M. J. HAMBLIN. 25 April, 1969 [27 Jan., 1968], No. 4379/68. Heading B8N. Apparatus for filling containers, e.g. bottles with measured quantities of liquid includes a plurality of metering units, each unit comprising a piston freely movable in a cylinder, and a rotatable valve for permitting supply of liquid to one side of the piston and discharge of liquid from the other side of the piston and vice versa. As illustrated in Fig. 3 a piston 14 is movable in a transparent cylinder 13, and with the rotary valve 41 in the position shown liquid under pressure supplied via pipe 17 passes via pipe 47 into the upper end of the cylinder. The piston is thus forced down to discharge via bores (not shown), bore 53 and leftmost passage 52 liquid contained below the piston. Rotation of the valve to a second position reverses the action of the unit. The valve, supply pipe 17 and outlet pipe 18 are retained in bores in valve housing 15 by a shoe 57 provided with slots 59, 60 for the pipes and a spindle 42 of the valve. The cylinder frictionally receives end-plates 44, 45. As shown in Fig. 1 the metering units are clamped on an annular plate 23 for rotation with a turntable 20. Bottles fed by a conveyer 33 are diverted on to the turntable by starwheel 31 to position a bottle under a respective metering unit. The presence of a bottle is sensed by a detector and a rack 40 is lowered to effect rotation of a pinion 21 to connect the previously exhausted side of the piston with the supply pipe 17. The filled bottles are diverted by a starwheel 32 back on to the conveyer 33. Each operation of a metering unit may only partially fill a bottle and further means may be provided for repeated rotation of the valve during passage of a bottle to the starwheel 32. The pinion may engage with spaced projections or rack segments to first position the valve for rapid filling of a bottle until almost full and then to position the valve for completing the filling more slowly. The amount of liquid dispensed by each unit can be varied by placing different size cylindrical rings 62 on the piston. Feed and delivery may be effected by separate conveyers. A metering unit per se forms the subject matter of Specification 1,270,262.

Abstract: 607,829. Pulse modifying circuits. WESTERN ELECTRIC CO., Inc. Feb. 12, 1946, No. 4388. Convention date, Feb. 15, 1945. [Class 40 (vi)] Signal pulses, which may have been shortened by radio transmission, are converted to a desired length by combining them with a delayed version of the same pulses, the delay being not greater than the length of any pulse. In one embodiment, pulses from the amplifier 21, Fig. 2, are fed to the clipper 22 and a delay network 26 is connected across the connections between the two circuits. The pulses entering the network are reflected from its opencircuited end, and on reaching the input end, combine with undelayed pulses to lengthen them by a time equal to twice the delay of the network. The clipper 22 removes the double amplitude overlapping portions of the input pulses applied to it. In a further embodiment, a clipper 34, Fig. 3, is fed with undelayed pulses from an amplifier 31 and pulses from a parallel amplifier 32 delayed by passage through a delay line 33.
