Class 29 In a machine for the intermittent or continuous freezing of ice comprising one or more oblong cans 1<SP>1</SP> mounted upright within an evaporator 6' and provided with bottoms 10<SP>1</SP> adapted to be lowered for harvesting the ice blocks, the evaporator space around the cans is transversely subdivided by ribs 15 with openings for the passage of the refrigerant. The hollow bottom 10<SP>1</SP> is pressed up against the open bottom of the can 1<SP>1</SP> by a spring 41 on a rod 42, and the can has a lid 14 pivoted on a vertical pin 19. The lid is swung open and water is supplied from a tank 3 to a distributor 32 so that it falls down the sides of the can, and refrigerant is supplied to the evaporator jacket 6<SP>1</SP> by a pipe 8 and withdrawn to a compressor by pipes 9, 62. When the water reaches the level shown dotted, the valve 31 is closed and the lid 14 replaced. Air is supplied to the water by a pump 52 through a flexible connection 55, the hollow bottom 10<SP>1</SP> and a clock valve 38 and is withdrawn by a pipe 69 and recirculated by pipe 28, outer jacket 26 of.the evaporator and pipe 27 to the pumps 52. When the water has frozen hot refrigerant is introduced into the evaporator 6<SP>1</SP> and a warm fluid such as hot water, steam or hot air is supplied to the outer jacket 26 through pipes 64 and 27 and exhausted through pipes 28 and 46. The bottom 10<SP>1</SP> is then lowered to harvest the ice block. For a continuous process the bottom is partly lowered and water is supplied to the can to fill the space above the lower ice block, and this is repeated until the protruding portion of the block is of the required length. This is severed at or near the bottom of the can by a hand tool or automatic ice cutters, and removed, and the bottom raised to continue the cycle. Two banks of cans may be operated alternately, one bank freezing while the other is harvesting. The ribs 15 form rings or spirals round the cans.

Filed: 1957-10-14
Abstract: 871,249. Coin-freed apparatus. FISHER & LUDLOW Ltd. Jan. 13, 1959 [Oct. 14, 1957], No. 31960/57. Class 27 Mechanism for diverting undersize and ferrous coins to return shoots 35, 36 comprises a downwardly and laterally inclined runway 23 backed by a wall 19 of which the major portion 25 is bent outwardly about a line 26 below the centre of an undersized coin so that such a coin will fail to be supported by a lip 27 and will tilt and slide off the chamfered edge of the runway into the shoot 35. A plate 32 forming a passageway for the ferrous test has a bent-over edge 33, 34 so that only correct coins that have remained on the runway without tilting will pass through a narrow entry into the passageway. A correctsized coin hits a stud 37 and is deflected so that it just touches a permanent magnet 39 and, if genuine, will fall to the left of a stud 38 and to a steadying member 43 before passing to the actuating mechanism or, if counterfeit, will be sufficiently attracted by the magnet to fall to the right of the stud and thence to the chute 36. The effective strength of the magnet can be varied by adjusting the number of laminations of a non-magnetic insert fitted between it and a panel 18 and also by using a fixing screw 42 of a series of different ferrous or non-ferrous materials. A flange 22 prevents coins from bouncing as they pass the bent-out wall 25 and prevents insertion of a ruler into the mechanism through the coin slot.

Filed: 1938-11-04
Abstract: 520,954. Photographic cameras. KODAK, Ltd. Nov. 4, 1938, No. 31986. Convention date, Nov. 13, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 6, 1939]. Drawings to Specification. [Class 98 (i)] The shutter release trigger of a photographic camera has two directions of movement, one causing relative movement between two shutter members to create an exposure aperture between them, and the other permitting both members to move together under the action of a power device to make the exposure. The invention is described in connection with the focal-plane shutter also described in Specification 520,957, in which depression of the shutter release knob releases the front blind allowing it to move relatively to the rear blind sufficiently to form a slit the width of which is determined by the setting of the speed control. On releasing pressure on the knob it is returned by a spring, both blinds being then released to make the exposure with the already-established slit. Specification 513,738 also is referred to.

Title: Improvements in absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1946-10-30
Abstract: 648,673. Refrigerating; cooling gases. ELECTROLUX, Ltd. Oct. 30, 1946, No. 32213. Convention date, Nov. 8, 1945. [Classes 29 and 64(iii)] In an absorption refrigerating system of the continuous cycle inert gas type, the inert gas streams passing through an upper precoolinig evaporator 13, an intermediate low-temperature evaporator 17 and a lower high-temperature evaporator 32 are so controlled that the rate of flow through the low temperature evaporator is greater than the rates of flow through the other two evaporators respectively. Liquid refrigerant from a condenser 12 enters the pre-cooler 13 and passes to chamber 15 whence it overflows through the low temperature evaporator 17 and the high temperature evaporator 32 and a U-tube 44 into a chamber 33. Weak insert gas from the absorber 18 traverses the gas heat exchanger 19 and flows through the evaporator 17 to the chamber 15 in counterflow to the liquid refrigerant. It then flows down a pipe 30 to a point 31 where it divides, part passing through the evaporator 32 and part passing into the chamber 33. The latter part flows into a pipe 38 and again divides, part flowing through a pipe 40 to the precooler 13 and part entering the gas heat exchanger at 42. The return inert gas, flowing through pipes 41, 42 and 36, enters the gas heat exchanger at points where the main gas stream temperature is equal to the temperature of the incoming gas. If the liquid refrigerant is not entirely vaporized in evaporator 32, the chamber 33 fills with liquid until the pipes 30, 38 are blocked which forces the entire gas stream through the evaporator 32 to evaporate the refrigerant therein. The pipes 30, 38 have holes 45, 46 within the chamber 33 so that a little gas may flow through to evaporate the liquid in the chamber and thus reset the control arrangements. In a modification, Fig. 2 (not shown), the inert gas flows in counterflow to the refrigerant in the evaporator 32 as well as in the evaporator 17 and the gas outlet from evaporator 32 is not introduced into the gas heat exchanger but is led in heat exchange therewith and is united with the gas from the precooler. This mixture is led into the absorber vessel and there undergoes a drop in partial pressure of ammonia before reaching the absorber coil where it unites with the gas stream from the evaporator 17. Fig. 4 (not shown) illustrates a practical form of apparatus and also embodies a pressure vessel and a U-tube to drain liquor from the rectifier into the absorber. Numerical examples of partial pressures of ammonia and the volumes of gas flowing in the several parts of the system are given. Specifications 494,693 and 648,737 are referred to.

Abstract: 393,272. Barometers and altimeters. KOLLSMAN, P., 47, Dinsmore Place, Brooklyn, New York, U.S.A. Nov. 20, 1931, No. 32233. [Class 106 (ii).] A barometer or altimeter supports pressures solely by the strength and elasticity of its walls and without the support of any internal or external spring force. In a simple form, Fig. 6, the capsule 10 has centre pieces 16, 17, the former mounting the capsule and the latter being connected to the temperature compensator link 18 connected to gear segment 19 pivoted at 20, counterweighted at 21 and engaging with a pinion 22 for rotating the pointer 23. The walls of the capsule 10 remain concave up to the maximum reading and are provided with a plurality of uniform corrugations 14 of substantially uniform depth slightly less than that of the outermost corrugation which runs to the flange reinforcement 15. A plurality of capsules can be axially secured together by centre pieces which may be small bars or discs having ends or faces directly externally secured to the capsule walls, so that the boxes may be close together and operate as a unit. The altimeter 24, Fig. 2, has two standards 34, 35 adjustably sprung apart for setting purposes by the screw adjusted leaf springs 37, 38 and rigidly connected to the disc 32 rigidly secured to the flange 33 at 28. The centre piece 16 of the capsule 10 extends through hole 42 in standard 35 and is adjustably locked by setscrew 43, whilst the centre piece 17 is connected to the link 44, connected to the set-screw adjusted resilient arm 45 of the shaft 46 journalled in disc 32 and in bracket 47 mounted on standard 34. A bendable strip 56 of different metal is secured to the link 44 to form a temperature compensator. Shaft 46 rotates segment 49 and hence pinion 50 connected to spindle 51 carrying pointer 52 reading on the dial 26 having gear teeth 29 engaged by pinion 30 turned by knob 31 for any desired setting. The spindle 51 is journalled in disc 32 and in plate 53 and carries a hair spring 54 which may be supported against lateral deflection, by disc 55 secured to the spindle, for accuracy in reading if the pointer is arranged to make many rotations. Fig. 5 shows a temperature compensator 57 consisting of an elongated straight bimetallic strip passing through a hole in, and adjustably screw-connected to, the element 58 attached to the wall 11 of the capsule 10. A link such as 18 or 44 is pivotally connected to the end of the compensator 57. The capsule 10 and compensator strip 57 form a unit which can be adjusted for temperature compensation by longitudinal movement of the strip 57 relative to the element 58 before being assembled in the instrument and connected to the mechanism for operating the indicating means. To facilitate calibrating the altimeter, a light tension spring 60 may be connected to the capsule 10 and to an arm 61 of standard34.
