Title: Improved method and apparatus for freezing a liquid
IPC: F25C5/10
Filed: 1958-09-15
Abstract: 874,278. Ice-making. WILBUSHEWICK, E. Sept. 15, 1958, No. 34010/60. Divided out of 874,277. Class 29 Relates to apparatus for carrying out the invention described in Specification 874,277 in which material in containers A is chilled by inserting the containers each into a housing 6 through the open bottom, closing the bottom 9, running water into the interspace 68, freezing the water and chilling the material by jacket and central evaporators 8, 7, supplying hot refrigerant to the evaporators to break the ice bonds and allow opening of the bottom 9, and removing the container from the housing. During freezing, liquid refrigerant from condenser 16 flows through pipe 1, expansion valves 11, and control valves 10 to the inner pipe 7a of central evaporators 7 whence it flows through the outer pipes 7b and connector pipes 7c to the jacket evaporators 8, the evaporators being connected to the compressor suction through control valves 10, common line 2 and receiver 19. At the end of freezing, control valves 10 are actuated to cut off the evaporators from communication with pipes 1 and 2 and to make other connections so that the following happens. Hot gas from the compressor outlet flows through pipe 4 and control valves 10 to the evaporators and forces liquid refrigerant therefrom through pipes 8c, the control valves 10, and common pipe 5 to a receiver 14, the ice-bonds in the housing being broken and the containers A removed. Fresh containers are then inserted, the bottoms 9 are closed, and water is admitted. Control valves 10 are so actuated that the evaporators are no longer in communication with hot-gas pipe 4 but pipe. 8c communicates with common pipe 5 so that liquid refrigerant can enter the evaporators from receiver 14, the bottoms 9 being quickly sealed by freezing of the water. Control valves 10 are then actuated to restore the normal freezing cycle. Liquid from receiver 19 can enter the evaporators during both the freezing and the liquid return-stages. The various .housings may work in anti-phase by appropriate operation of control valves 10. The water supply is pre-cooled by an auxiliary evaporator 13 supplied from common pipe 1 through expansion valve 11a. Specification 802,593 also is referred to.

Abstract: 1,024,345. Doll's eyes. INSTITUT FUR SPEILZEUG SONNEBERG/THUR. Aug.29, 1963, No. 34220/63. Heading A6S. A doll's eye formed as a unit in a casing has a weighted part-spherical eyeball mounted to swing horizontally and vertically. The unit comprises a casing having an arm 7 protruding into the centre and supporting on a horizontal pin 6 a rod 5 on which the eyeball unit 1 is mounted. Under the influence of a counter weight 10, the eyeball 1 and lid 8 pivot about the horizontal axis 6 to close the eye when the doll is laid down. During rapid sideways movement of the doll, the eye turns sideways about the rod 5 under the influence of the counter weight to give a roguish look. Such movement does not rotate the lid about this axis as it is held against such movement on rod 5 by a support rod 13 pivoted also on the horizontal pin 6 and passing through an arcuate slot 11 in the eyeball which slot limits the horizontal movement of said eyeball.

Title: Improvements in and relating to adjuster mechanism for independent wheel suspensionsand the like
Inventor: BOOTH JAMES H
IPC: B62D17/00
Filed: 1953-12-10
Abstract: 736,285. Rod joints. THOMPSON PRODUCTS, Inc. Dec. 10, 1953, No. 34435/53. Class 99 (1). [Also in Group XXXII] A mechanism for adjusting and fixing the length of a lever comprises a tapered arm connected to one part of the lever, an externally threaded split sleeve having a tapered bore receiving the arm and being threaded into a threaded bore in a second part of the lever, the end of the arm projecting through the bore and being threaded to receive a nut so that after adjustment by rotation of the sleeve the length of the lever may be fixed by tightening the nut. In the arrangement shown as applied to a vehicle front steerable wheel suspension comprising upper and lower suspension links 16, 29 connected to a steering knukle 12 through ball joints 14, 15, the joint 14 includes a tapered shank 45 received in the tapered bore 38 of an externally-threaded split sleeve 36. The sleeve is screwed into a tapped hole 35 in the arm 16 and is locked in an adjusted position therein by the wedging action of the shank 45 as the latter is secured by a nut 49. The adjusted position of the sleeve 36 thus determines the camber of the associated road wheel. The connection of the lower link 29 to the joint 15 is effected in similar manner, the bore of the sleeve in this case being eccentric to the axis of the sleeve, the rotational adjustment of which thus determines the castor angle of the wheels. Specification 652,434, [Group XXXII], is referred to.

Filed: 1961-09-26
Abstract: 993,060. Indicating-apparatus. NEDERLANDSCHE INSTRUMENTEN-EN ELECTRISCHE APPARATEN FABRIEK N.V. Sept. 26, 1961 [Sept. 30, 1960], No. 34505/61. Heading G1J. [Also in Division G4] A moving part, e.g. the pointer B, of a measuring instrument carries two tags C, D one of which C is nearer to the pointer axis than the other. Each tag is associated with a respective sensing device, e.g. photosensitive resistors F 1  F 2  responsive to separate or to one axially mounted light source E. Each tag influences its respective sensing device when the pointer deflection reaches a limit value, and both sensing devices then initiate the same control action, e.g. operate a warning signal or regulate a process. The purpose of the nearer tag C, which is of larger dimensions than the tag D, is to maintain the control action when the pointer deflection increases beyond the limit value to such an extent that the tag D no longer stops the light beam from source E falling on the resistor F 2 . The photo-resistors F 1 -F 2  may be adjustably mounted to vary the limit value and a further pair of photo-resistors G 1 -G 2  may function similarly to exercise a further control at some other adjustable value of pointer deflection. Inductive sensing devices Figs. 2-4 (not shown) may be used.
