Abstract: 1,249,717. Dyeing pile fabric. P. ZIMMER. 9 Dec., 1969 [10 Dec., 1968], No. 60464/69. Heading D1L. Dye liquor is applied to a travelling web of pile fabric 6 as a film 3' from a rotating screen cylinder 1 by the action of a pair of squeegees forming a nip through which the cylinder passes. A plurality of films may be applied using a single cylinder and a plurality of spaced pairs of squeegees. The driving means for the web and cylinder may be coupled. As shown, the liquor is supplied to the nip from a supply pipe 2 and the squeegees are in the form of magnetically attracted rolls 4 and 5. The cylinder may be lowered so that roll 5 touches the web which may be supported by a roll 7. Alternatively, one (Fig. 4 or 5) or both (Fig. 3) squeegee rolls may be replaced by a blade; and the liquor may be applied to the upper inside wall of the cylinder from an applicator roll (Fig. 6).

Filed: 1970-12-21
Abstract: 1298290 Retractive switches INTERNATIONAL BUSINESS MACHINES CORP 21 Dec 1970 [23 Jan 1970] 60508/70 Heading H1N A switch comprises a fixed contact 27; a movable contact 24 mounted on a diaphragm 23 and an actuating member 20 located on the other side of the diaphragm to the contacts and having a projection 21 facing the diaphragm whereby on depression of the actuating member which is of elastic material the projection urges the contacts into engagement. The contacts 24, 27 are gold-plated copper laid on polyester diaphragms 23, 30; a separator sheet 25 having holes aligned with the contacts is placed between them. The actuating member is of solid neoprene and besides projections 21 has further, shorter projections 22 which limit travel and prevent damage to the contacts or diaphragm 23. Above the actuating member rests a thick block 16 of soft closed-cellular neoprene and above this, resting on a rigid aluminium frame 15 is an actuator sheet 10, 14 of polyurethane elastomer having raised portions 11 marked with indicia (Fig. 2, not shown). The sheet 10 can be readily removed and replaced by another bearing alternative indicia. The block 16 gives the switches a suitable "feel" and allows pretravel and overtravel. The stop projections 22 may be arranged in a circle or a square depending upon the shape of the raised operating portions 11; they may be discrete projections or a continuous ring surrounding the projection 21. More than one projection 21, each operating a pair of contacts, may be associated with a group of projections 22 below a single portion 11.

Abstract: 1,218,620. Proteinic compositions. ROHM & HAAS G.m.b.H. 20 Dec., 1968 [27 Dec., 1967], No. 60811/68. Headings C3H and C3P. [Also in Division A5] A water-insoluble composition comprises a water-insoluble polymer or copolymer of acrylic and/or methacrylic anhydride and a proteinic substance containing at least one α- or #-amino group, the said proteinic substance being covalently bonded to the said polymer or copolymer through reactive groups on the polymer or copolymer. The proteinic substance may be an enzyme, polypeptide, antigen or antibody. The polymer or copolymer may be cross-linked either with a di- or polyamine, or may be cross-linked by copolymerizing with a monomer which contains at least two carbon-carbon double bonds. In the examples (1) polymethacrylic anhydride, cross-linked with hexamethylene diamine, is reacted in an aqueous medium with either trypsin or papain, (2) a cross-linked copolymer of methacrylic anhydride and divinyl benzene is partially saponified with ammonia and reacted with chymotrysin, and (3) a cross-linked copolymer of methacrylic anhydride, methacrylamide, methacrylic acid and ethylene glycol dimethacrylate was reacted with a pancreas preparation (containing trypsin and chymotrypsin). These reactions were carried out by stirring the resin and protein at ambient temperature, and separating the 'resin-protein' from the aqueous medium.

Filed: 1979-04-12
Abstract: Portable tester and method for testing a variety of circuit boards without utilizing adaptor boards for re-routing input test signals and supply voltage from the tester to pins of the board under test. A plurality of edge adaptors having different pin spacings have their respective pins connected in parallel to corresponding edge connector stake pins. Each edge connector stake pin is connected to or isolated from the corresponding driver/sensor stake pin by means of a switch. Each driver/sensor stake pin is connected to the input/output terminal of a programmable driver/sensor circuit. A plurality of power supply stake pins are connected to various power supplies of the portable tester. Connectors coupled to the family board can be utilized to route power supply voltages to electrically isolated edge connector stake pins. Isolated driver/sensor outputs can be routed to other edge connector stake pins. A main processor stores a test program and transmits data and control information to predetermined driver/sensor circuits. A high speed processor is coupled between the main processor and the inputs of the driver/sensor circuits. The high speed processor memory can store a bus-defining subroutine containing a sequence of data shifting instructions which shift a word in the shift register to the input of specified driver/sensor circuits at high speed. The high speed processor can synchronize the operation of the portable tester with an asynchronously operating printed circuit board under test.

Patent GB-801692-A (GB)
IPC: A21C11/00
Abstract: 801,692. Pie-moulding machines. PEERLESS & ERICSSON, Ltd. Oct. 3, 1956 [Oct. 14, 1955], No. 29392/55. Class 87(2). Each baking tin carrier plate 23 carries four blocks 25 positioned by spigots 24 in equally spaced holes in the carrier plate. The baking tin carrier plate 23 is similarly positioned on an intermittently revolving table, not shown, by a nut 29 which functions as a spigot. The nut 29 tightens a screw 28 and clamps the edge of a disc 27 against shoulders 26 on the blocks 25, thus holding them in place. Each block is recessed at 31 to receive a baking tin 47. Dies 34, to shape the pastry in the baking tins, are carried by the arms of a spider 32 secured to a central post 14. The lower edge of each die is slightly chamfered and the chamfer is continued by the edge of a disc 38 which is relatively movable to, but normally pressed against, the lower face of the die by springs 39 under the heads of bolts 40 projecting from the disc. A ring 37 surrounds the die and is serrated at its lower edge. The exposed surfaces of the disc 38 are roughened. The dies are slidable through openings in the lower wall 42 of a housing 41 surrounding the spider 32, each opening having a cutting edge 43 around its rim. A pair of plungers 45, guided in tubes 44, are urged downwards by springs 46 and, projecting below the cutting edges 43, serve to hold down the rims of the baking tins. The post 14 enters a hollow in the end of a vertically reciprocable rod, where it is held by a tangential pin which engages a groove 16 in the post, and a tubular foot surrounding the rod carries the housing 41 and is separately reciprocable, forming a trimming unit which moves up and down with the dies and also performs an additional vertical movement relative thereto. The operator places a plate 48 over the blocks with apertures just large enough to fit over them ; baking tins 47, slightly larger in diameter than the blocks, are placed in the recesses 31 ; the table is rotated to carry the tins to a filling position where pastry is deposited in them ; then rotated to position the tins under the die head, where the dies descend to mould the pastry, the ring 37 producing decorated edges and the housing 42 moving down when the die head has reached the bottom of its stroke, so that the edges 43 trim excess pastry ; the table is further rotated to carry the tins to an unloading station and the plate 48 is lifted and the tins with the moulded pastry are removed simultaneously. The spring-loaded discs 38 reduce the tendency for the moulded pastry to stick to the dies on their return upward stroke, since they allow the dies 34 to commence to rise independently, whereupon air enters between the roughened surface of the discs and the pastry which is thereby freed.
