Title: Improvements in press for cutting or punching sheet material
IPC: C14B5/00
Filed: 1920-07-02
Abstract: 146,403. Reece Shoe Machinery Co., (Assignees of Schoenky, A. R.). Dec. 8, 1916, [Convention date]. Cutting-out apparatus. - A power press for cutting out or punching leather or other sheet material, of the type described in Specification 16488/04, has an upright presser-carrying pillar and a laterally swingable presser carried thereby and co-operating with a bed carried by the machined frame, the presser being arranged to swing in relation to the pillar, which is non- rotating, and not adjustable, but is given an upward and downward constant-throw reciprocating movement under hand or foot control. The bed is adjustable vertically. The presser comprises in one casting a head 15, an upper rotary bearing 19, a downward extension 20, and a lower rotary bearing 21, the upper bearing being confined between a shoulder 22 and a thrust bearing 23 on the pillar 18. The pillar 18 slides within guides constituted by bearings 27, 28 disposed on the frame of the machine and in relation to the bearings 19, 21 as on the Figure. Both up and down strokes of the pillar 18 are power driven, a block 34 secured in the foot of the pillar by a transverse pin being coupled by a short connecting rod 35 to an eccentric on a shaft 31. This shaft is driven through a trip clutch from a pulley 30. The clutch, Fig. 4, comprises hardened shoulders 39 on the pulley engaged by a spring-pressed pivoted dog 46 in a collar carried by the shaft 31 and controlled by means of a shoe 49 adapted to engage a pin 48 projecting from the dog, the shaft being stopped by means of a friction band and felt continuously acting upon the collar. The sleeve 49 is pivoted upon a fixed lug 52 and its operative position maintained by an adjusting screw 56 and spring 55, Fig. 1; it is actuated to free the dog 46 and start the machine by a handbar 64 or foot control 62 coupled together by rods 63 and to the shoe by levers 61, 59 and a rod 58. To permit the foot control to be moved out of the way, the levers 59, 61 are pivoted upon lugs 66 adjustable upon fixed frame bars 67. The bed 12 is carried by a cylindrical ram 69 adjustably supported in the frame by a screw 75 engaging a member 79 integral with or secured within the ram. This screw is operated by a hand-wheel 76 and has a collar 77 resting upon an apertured plate 78 confined within the lower end of the hollow frame. The frame is split and carries lugs 73 through which a screw 74 passes, whereby the bed may be clamped after adjustment. Specifications 3276/79, [Class 17, Boots &c.], and 22023/05 are also referred to.

Abstract: 1,190,625. Slicing tomatoes &c. SANDERS & BOWERS Ltd. 19 Feb., 1968 [21 April, 1967], No. 18405/67. Heading A4C. An apparatus for slicing foodstuffs such as tomatoes comprises two sets of blades 1 alternating with and evenly spaced from each other axially of a cylindrical space 2 surrounded by their cutting edges 3 which are broken by notches 4 and extend over rather more than 180 degrees of the blades, and a set of spaced curved bars 31 which force the article to be cut, which is placed in the space 2, on to the cutting edges 3 of the blades 2, said sets of blades being caused to rock in opposite directions. The blades of each set are moulded to a hub 7 by means of integral projections 5 with elongate holes 6 each hub being detachably carried by an arm 8, said arms having a common pivot 13 coaxial with the blades 1, the cylindrical space 2 thus being in a horizontal position between the sides 14 and 16. A crank disc 17 and handle 18 outside the casing is connected to the arms 8 through parts 20-22 and causes the blades to oscillate. Inside the walls 23 and 24 are vertical guide rods (25) each of which is threaded with a compression spring (26) upon which rests a guide sleeve 27 carrying a plate (28) passing through a vertical slot 29 in the wall 16 to carry a support and operating bar 30 for the arcuate bars 31 which are carried by a central plate 32 extending into the top of the space within the blades 1. Any portion of material which protrudes from the space 2 is severed by the sharp edge (37) of the inturned rim 35 of side wall 16 while the innermost penetration of such material is determined by a vertical plate (38) inside casing 15. The handle 18 for oscillating the blades and the bar 30 to operate the bars 31 are operated manually although the blades may be driven by a motorised drive. In an alternative. embodiment the guide rods 25 and operating bar 30 may be replacing by a swinging operating bar pivoted beyond one side of the blades 1 at approximately the height of the axis of the space 2, the operating arm extending beyond the opposite side of the casing for manual operation.

Title: Improvements in textile fibre-drafting elements
IPC: D01H5/74
Filed: 1950-07-25
Abstract: A textile fibre-drafting element has a drafting surface presented by gas-filled, cellular, oil-resistant, vulcanized synthetic rubber made from a mix which has an ingredient or, alternatively or in addition, subjected to treatment, which does not oppose formation of the cellular structure but results in the rubber comprising the element having a hardness substantially greater than would be produced by vulcanization in the absence of any said ingredient or treatment. The ingredient may be phenol-formaldehyde resin or sulphur in an amount substantially larger than the usual.  Butadieneacrylonitrile is a specified resin and 85 degrees Shore a specified "greater hardness."

Title: Improvements in and relating to shaft couplings
IPC: F16D3/06
Filed: 1919-07-26
Abstract: 152,795. British Thomson - Houston Co., (General Electric Co.). July 26, 1919. Separating oil from water.-Water, mixed with waste oil supplied to a shaft coupling for lubricating purposes, is separated continuously from the oil during the running of the coupling. The mixture of oil and water is supplied to the space between the ends of the shafts and is thrown by centrifugal force to the periphery of the casing 18. The water, being heavier, is thrown to the point b into an annular ring of greater diameter than the casing. The ring communicates by a hole 28 with a radial bore having a discharge passage 31. In operation, the water discharged into the radial bore forms a balancing column to the combined column of water and oil remaining in the ring and casing. The accumulation of additional water in the ring upsets the balance and causes more water to pass into the radial bore. Finally, the excess water passes out of pipe 31 and is guided by the annular guard 32 to a discharge pipe.

Abstract: 1,246,414. Semi-conductor devices. ITT INDUSTRIES Inc. 11 April, 1969 [11 April, 1968], No. 18795/69. Heading H1K. In a semi-conductor device including two superimposed dielectric layers, e.g. SiO 2  layer 5 and glass layer 10, on a semi-conductor surface, undesirable migration of ions from an Ag electrode dot 7 into the upper dielectric layer 10 is prevented by the provision of a coating 9 of a conductive barrier material over the dot 7. In the diode shown, the Ag dot 7 is alloyed on to a preliminary Au/Ni layer on the semi-conductor surface, and the barrier coating 9 is of Ni. Alternative barrier materials are W, Mo, Pt, Pd or Rh. Application of the coating 9 may be by electroless plating or electroplating. The lower electrode 8 comprises Sn-coated Ag. The glass layer 10 is applied initially as a frit and is fused after having been removed from the surface of the upper electrode and from channels around individual devices in a wafer. The wafer is then scribed and diced in the channels. Transistors and integrated circuits are also referred to.
