Title: Continuous Production of Fresh Cheeses
IPC: A01J25/00
Filed: 1966-05-12
Abstract: 1,154,453. Cheese curd. PARACURD S.A. 12 May, 1966 [12 May, 1965], No. 21189/66. Heading A2B. A fresh cheese, of the type such as cream cheese or cottage cheese, is obtained without the use of rennet in a process which comprises concentrating the milk, acidifying to a pH of about 5, mixing this acidified milk with hot water, and then draining off the liquor from the resulting curds, which are thereafter subjected to conventional steps such as cooling and homogenising. The acidification may be effected by the action of lactic ferments such as streptococcus lactis or streptococcus cremoris, or by the addition of acids. A suitable device for mixing the concentrated milk with the hot water comprises an axial tube for the supply of concentrated milk having at its lower end a series of jet-forming slots for injecting the milk laterally and initially at right angles into a quiescent axial flow of hot water surrounding the tube, the device further comprising an inlet for hot water with means for removing turbulence from its flow from the inlet to where it mingles with the jets of milk. Fig. 2 shows a preferred construction, the milk entering via tube 8, which is surrounded by a jacket 9 for a flow of cold water, and provided with slots 12, whose effective size may be altered by piston 13. The hot water enters via line 14, and turbulence is removed by the baffle 15 with port 16 and mesh screens 17.

Abstract: 782,720. Clocks and watches. TAVAN. NES WATCH CO., SOC. ANON. July 27, 1955 [Aug. 28, 1954), No. 21679/55. Class 139 In an alarm timepiece the hour wheel is moved axially by a spring pressed rigid lever to release the alarm hammer and the said lever arrests the alarm mechanism after a predetermined unwinding of the alarm spring. The hour wheel 6, Figs. 1 and 2, rotates above the alarm wheel 8 and is urged downwardly by a lever 5 acted on by a spring 13. A nose 15 of the lever 5 normally engages a pin 16 on the alarm hammer 4 which is thereby locked. When two pins 9, 10 on the hour wheel 6 coincide with two slots 9a, 10a on the alarm wheel 8 the spring 13 is effective and axially moves the hour wheel 6 through the lever 5 which frees the hammer 4 for actuation by the alarm spring. A gear 17 is rotated by the alarm spring and rotates a coaxial heart-shaped cam 19 through a lost motion pin and slot connection 20, 18 until a conical projection 14 on the cam 19 meets a projection 21 of the lever 5. The hour wheel 6 continues to rotate and the pins 9, 10 ride out of the slots 9a, 10a so that the lever 5 is returned to its initial position and. the projection 21 frees the pin 14 whereupon a spring 22 moves the heart-shaped cam to its initial position.

Abstract: 906,553. Reciprocating pumps. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 27, 1960 [June 27, 1959 (3)], No. 22147/59, 22148/59 and 22149/59. Class 102(1). [Also in Groups XXVI and XXIX]. In a revolving cylinder pump or motor, comprising ball pistons 3, Fig. 1, reciprocable in radially disposed cylinders in a rotary cylinder block 1 by means of a cam ring 4 having radial clearance between it and the block, each cylinder is fitted with a liner 30, Fig. 3, of hard low-friction material such as tungsten carbide to reduce wear between the ball pistons and the cylinders. The liner has an external diameter at its inner end 32, greater than at its outer end to form an intermediate shoulder 31. The enlarged diameter of the inner end 32 is such that on the liner being cooled in a refrigerator and the cylinder block being heated to a relatively high temperature the liner may be inserted in the cylinder bore 29. The axial lengths of the inner end 32 and the corresponding undercut in the cylinder bore are such that when the parts return to normal temperature the end 32 is securely locked in the undercut by axial compression of the end 32. A fixed pintle 14 having longitudinal ducts 15, 16, Fig. 2, connected to transverse upper and lower grooves, 17, 18 through suitably arranged ports 20, 23 distributes the hydraulic operating fluid to and from the cylinders in the usual manner through cylinder ports 19. The pintle 14 may be angularly adjusted with respect to the ports 19 to promote smooth running of the pump by means of an eccentric pin 24 carried on a stud 25 and working in a longitudinal groove 27 in the flanged end 28 of the pintle. The instant of cutoff of the ports 19 being delayed at the ends of the delivery (pump) or power (motor) strokes of their respective pistons so as to allow the pistons to commence their suction or exhaust strokes before the ports are opened to the oil at inlet or exhaust pressure, as the case may be. The pump or motor is shown with four rings of pistons and cylinders each with its own cam ring pivotedly mounted on a shaft 7 which carries four eccentric sheaves 8 snugly lying between horns 9. The eccentricities of the sheaves are alternately arranged at 180 degrees with respect to each other, the throws being equal so that when the shaft is rotated by means of a rack 11 and pinion 10, adjacent cams 4 are adjusted equally in opposite senses. The shaft 7 may be rotated manually or automatically so that the stroke of each ball is dependent upon the load demand of the machine being driven. The axis of each cylinder is set at a slight angle to the radius of the cylinder block to reduce the lateral forces between the balls and the cylinder bores. The track of each cam ring 4 is grooved at 34, Fig. 7, to reduce the Hertzian stresses set up in the ball by the fluid pressure during each pumping or power stroke to further reduce rate of wear.

[Class 3 (i)] Optical-projection apparatus.-A disc transparency is so mounted as to be uniformly rotated through one revolution by a clockwork motor, and then automatically stopped till again manually actuated. Fig. 2 shows one form in which a disc carrier 5 comprises a grooved annulus rotated by a cord 10 passing over the motor pulley 11 and tensioned by a jockey pulley 14. The annulus 5 is journalled at 11<a> in laterally adjustable bearings, and carries a radial projection 23 having an opening 22 adapted to receive a removable slide 25. The transparency disc 9 is held to the annulus 5 by spring clips 15, and has the display matter arranged radially with one blank portion opposite the slide 25. On pulling away by hand a spring-pressed projection 28 from a slot 27 the carrier 5 is released and the motor started, rotating the disc 9 through one revolution, determined by the projection 28 snapping again into the slot 27 and also stopping the motor. The slide 25 may be changed by manual manipulation during the rotation of the disc 9, and the disc 9 may be changed during the stationary periods when the slide 25 is showing. Fig. 6 depicts a modification in which the display matter 49 is disposed circumferentially on the disc 9, the opening 50<a> being in a radius which is vertical when the opening is in the light beam. A disc support having both vertical and horizontal spindle adjustment may be used for accommodating both types of disc. The device may have its own optical lantern, or be readily attachable to a kinematographic projector, a gauze screen &c. being provided in the beam in the latter case to reduce the light and heat effects.
