Title: Removal of surface projections
IPC: H01L21/00
Filed: 1971-04-19
Abstract: 1319025 Removing projections INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [16 March 1970] 22789/71 Heading B5E [Also in Division H1] Frangible projections from a surface are removed by crushing them with a rigid element applied in a direction substantially normal to the surface with a force sufficient to fracture the projections. As shown, Fig. 1, a Si wafer 10 having an epitaxial layer 12 from which project epitaxial spikes and mounds 14 is positioned in a recess 22 in a hard rubber pad 20 mounted on a piston (44), the wafer being retained by a vacuum applied via pores 24 in the pad. The pad lies inside a chamber 27 the wall of which has an annular chamber 26 to which a vacuum may be applied to retain a glass plate 40 against annular seals 28. Chambers 26 and 27 are evacuated to force the wafer against the plate to fracture the spikes 14. The vacuum is preferably drawn rapidly to cause the wafer to impact against the plate. The vacuum is then released by applying sufficient force to the stem of the piston to break the seals 28, thus further crushing the spikes. The wafer is then separated from the plate and the debris removed by ultrasonically cleaning in alcohol and water.

A conveyer comprises a pair of opposed guides 26, 27 extending longitudinally of the path of travel defining a central slot therebetween and an endless link chain 18 received in the slot and in sliding engagement with the guides 26, 27, the planes of adjacent links being disposed obliquely to the plane of the guides and alternate links being disposed in opposite oblique directions and supported on opposite guides 26, 27. The guides 26, 27 are formed by the inturned upper and lower edges of an extruded frame 1 and the edges of the guides are faced with nylon. The upper and lower guides carry the loading and return runs of the chain 18, which frictionally engages and motivates the load for conveyance. An integral T-shaped slot 36, 37 running along each side of the frame 1 houses the heads of bolts and allows the shanks thereof to extend therefrom to mount rollers 2 and guide bars 3 for supporting and guiding the load being conveyed. The rollers 2 can be moved relative to the frame 1 by releasing the nut 53. The rollers are mounted on the ends of shorter bolts and intermediate the length of longer bolts which mount the guide bars 3 via supports 52. At the terminal stations of the conveyer, plates 4 are attached to the frame 1 by bolts in the T-slots, a support drive and idler chain sprockets therebetween. The idler sprocket is slidably mounted for chain tensioning via a threaded screw. Curves in the conveyer circuit, either in the vertical or horizontal planes, are created by bending sections of the frame 1 and coupling them to other sections by plates bolted to the sides thereof. At each joint a rod is inserted in the T-slot and extends from one frame section into its adjacent section, forming a rigid structure. In the embodiment of Fig. 8 (not shown) the rollers are replaced by support bars and the lateral guide bars are mounted directly on to the frame 1 through adjustable brackets.

Abstract: 933,363. Cleaning animal tissue; scraping tendons. JOHNSON & JOHNSON. June 26, 1961, No. 23106/61. Class 28 (2). In cleaning animal tissue, in particular tendons, the tendons are placed inside a cylinder 30 by removal and replacement of an end closure fitting 54, locked against inadvertent opening, and the cylinder is rotated so that portions of the tendons protrude through perforations 31 in the cylinder wall 33 and are scraped by a knife 80 resiliently urged close to the outer surface of the wall 33. At the same time, sprays of water are directed on to the inner and outer surfaces of the wall 33 by means of spray bars 112, 108 having nozzles 115, 110, respectively. Spray bar 112 is L-shaped and is connected to a pumped water supply through a hollow shaft 122 rotated within the cylinder-rotating shaft 38 at a speed faster than the latter (so that the entire inner surface of the cylinder wall 33 is sprayed) by means of a sheave 126 of smaller diameter than the sheave 46 on the cylinder shaft, both shafts having a common drive. Ducts 138, 136 supplying water to spray bars 112, 108, respectively, are equipped with solenoid-operated valves 142, 140 (Fig. 9), and are themselves fed with water, e.g. at 75‹ C., from a common duct 148 connected to a pump 150, a by-pass line 157 taking the water flow when the valves are closed. The sheaves 46, 126 are driven by V-belts from the drive-shaft pulley 130 of a motor 134. A common control means, e.g. an operative circuit including timing elements, is manually or automatically operable from a central control panel P to selectively actuate motor 134, pump 150, valve solenoids 144, 146, in timed cyclic relationship, the cylinder rotation and water jets being periodically interrupted to allow the tendons in the cylinder to re-orientate themselves and be evenly scraped.

Title: Improvements in or relating to fluid pressure brake systems
Inventor: BERG ARTHUR ABRAHAM
IPC: B60T8/18
Filed: 1960-07-04
Abstract: 961,300. Fluid-pressure brakes. BERG AIRLECTRO PRODUCTS CO. July 4, 1960, No. 23338/60. Heading F2F. In a fluid-pressure braking system comprising a source of fluid-pressure connected by a valvecontrolled passage to a brake, the control valve is arranged to be opened by a rock bar or arm 440 which is mounted for rocking movement on a movable fulcrum 416 controlled by a lever 403 linked to the vehicle so that the weight of the vehicle influences the position of the arm 403 and this movement is transmitted through a coil spring 409 which absorbs vibrational effects of the vehicle to control an arm 410 and thereby adjust the position of the fulcrum 416 along the under-surface of the rock bar or arm 440 according to the weight on the vehicle. When brake application pressure enters the passage 430 under the control of the driver the piston 434 and rod 437 are depressed and the rock arm 440 rotates in a counter-clockwise direction about the fulcrum 416. The movement of the arm 440 causes an upward movement of the push-rod 451 to lift a valve element 464 off its seat to permit the brake actuating fluid pressure present in chamber 465 to enter a chamber 480 and passages 481 for delivery to the brake actuating chambers (not shown). Reduction of the brake application pressure closes the valve 464 and returns the parts to the position illustrated in Fig. 2. Excessive pressure in passages 480, 481 remaining after the release of the application pressure from the passage 430 acts on the upper surface of the piston 455 so as to move the latter downwards and cause separation of the valve seat 457 from the valve element 471 to permit passage of the excessive air pressure through the valve 457 and apertures 458 into a vent chamber 454. The Specification discloses means whereby automatic operation of this system is caused to apply the brakes of the vehicle when there is a loss of pressure in the emergency air pressure system of the vehicle. A further embodiment (not shown) discloses a leaf-spring in place of the coil spring 409. In order to prevent excessive movement of the movable fulcrum member 416 a damper mechanism 418 is provided.
