Inventor: GRAINGER BERTRAM DONALD
IPC: B66F3/08
Filed: 1961-04-04
Abstract: 1,006,603. Screw jacks. METALLIFACTURE Ltd. Feb. 20, 1962 [April 4, 1961], No. 11919/61. Heading B8J. In a bipod jack having a screw 4, rotation of which raises and lowers the lifting member (not shown), the actuating nut 1 is mounted on the screw by means permitting universal movement of the nut with respect to the screw. As shown, a pin 3 is secured to and extends transversely of the nut, which has an internal bore 2, and passes through an aperture 7 of opposed conical form in the screw 4 so that the pin, together with the nut, can tilt between the faces 8 of the aperture 7 and the nut can also rotate about the axis of the pin. In a modification, Fig. 3 (not shown), the pin is fixed within the screw and engages in holes of greater diameter than that of the pin in the sides of the nut.

Abstract: 1285162 Pressing cheese curd NEW ZEALAND DAIRY RESEARCH INSTITUTE 28 April 1971 11982/71 Heading A2B Prepared divided curd is pre-pressed for a period of time and under such a pressure that the curd moisture content is reduced to the desired level, the pressure is released, the curd is partially redivided as and when appropriate, and passed to a press chamber which can be substantially hermetically sealed, reducing the gaseous pressure therein to below atmospheric, applying mechanical pressure to the curd to facilitate coherence and form cheese, and subsequently expressing the cheese from the chamber, said cheese and the pre-pressed curd from which it was formed having substantially the same moisture content. The prepressing may be effected in a tunnel having narrow longitudinal slots for drainage, with a restricted orifice such as a grid or backing cone plate, and a prepress ram or screw, and the curd may be at least partly redivided on issuing from the orifice, for example by providing a cone having concave walls near its base mounted coaxially to the curd flow to change the direction of the flow and cause crumbling.

Patent GB-401285-A (GB)
Title: Improvements in and relating to the manufacture of soap
IPC: C11D13/22
Filed: 1932-04-26
Abstract: In an apparatus for drying and crusting soap, a row of tablets of soap are fed to a tray in the crusting chamber, and alternate tablets are displaced across the tray to form two rows in staggered formation.  Rows of tablets formed by cutting up bars of soap are received on an intermittently moving conveyor 30.  A single row of tablets pass to a table 51 which rises with an adjacent tray attached to a conveyor 49 and is transferred to the edge thereof by a reciprocating pusher 58.  On its further upward movement, the loaded tray arrives opposite a second series of spaced pushers 71, which displace alternate tablets to the remote side of <PICT:0401285/III/1> the tray.  The trays are formed of spaced bars and are attached through self-levelling devices to an endless chain conveyor 49 which follows a tortuous course in the crusting chamber 21, through which a current of warm air passes.  The entry to the chamber is provided with a number of flaps 80 which prevent ingress of cold air.  When the trays arrive at the delivery end of the chamber, movable walls mounted at the ends of the descending trays are engaged by converging ramps whereby the walls move inwards closing the spaced tablets together.  On further downward movement, the ramps are separated by cams returning the movable tray walls to their original position. Finally the rows of crusted soap are removed by a roller 93 which passes over the tray to the rear of the soap tablets and transfers them to a delivery conveyor 96.  During loading and unloading, the trays are prevented from swinging by the engagement of rollers with channels mounted on the tray.

Abstract: 904,675. Grippers for lifting articles. ELECTRICITE DE FRANCE. April 6, 1960 [July 16, 1959], No. 12254/60. Class 78 (4). A device for picking up aligned cans 10, or other objects, includes a number of covers 5 placed over the cans, and gripping members 15, 15B, carried by a member 13 which is moved relatively to the covers 5 to grip the cans. Each member 15 or 15B has two arms such as 18A, 19A and is pivoted to the member 13 so that movement of the member 13 causes the arm 18A to press against one of the covers 5, thus moving the arm 19A beneath the cover 5 to retain a can. Instead of providing a gripper 15 on each side of each cover 5, as shown, a single gripper may be associated with each cover. The grippers may be mounted on arms 14 articulated to the support 13 so that the grippers are automatically aligned between the cans. Several cans, arranged in line axially, may be engaged under each cover 5. The grippers 15 may have teeth and may be shaped to fit the objects lifted.

Each beam comprises longitudinal spars 1, Fig. 1, with crossstruts 1b, 1c, and cutaway end pieces 1a. The end pieces 1a, 2a of adjacent beams of a group overlap, and support members 3 comprising flat plates with cut away ends 3a, 3c Fig. 2, are mounted with their upper tongues 3a between the end struts 1c, 1b, 2b, 2c of adjacent beams, and their lower ends between cross struts of foundation beams 4. The upper and lower shoulders of the support members 3b, 3d are curved about horizontally displaced centres, so that even when the supports are vertical, they have a tendency to swing back to an inclined position when they are supported by the chamfered edges of the cross-struts. The inner group of beams I, Fig. 5 and the outer groups of beams II, III are driven by a crank drive engaging end beams (Fig. 4) so that the inner set I move forwards and downwards while the outer sets II, III move forwardly and upwards. The drives are so arranged and the beams supported at such a level that, when the tiles are transferred from one set of beams to another, the beams have an equal forward component of velocity. The beams, support members and foundation beams, which may be replaced by beams identical with the carrier beams, are all formed of ceramic material.
