Title: Improvements in or relating to electric fuse boards, and the like
IPC: H02B1/48
Filed: 1923-06-06
Abstract: 221,018. Holmes & James, Ltd., and Sutherland, H. E. June 6, 1923. Fuse-boards.-Fuse bases a are mounted on a member b slidable outwardly from the back of a board br box so as to facilitate wiring &c. The member b has end brackets c slidable on projections d secured to the board or box. Screws e in the projections d passing through slots in the brackets c limit the inward movement of the member b by contacting with the outer end of the slots and the outward movement by contacting with the member itself. The member b may swivel about the screws in its outermost position, but by unscrewing the screws sufficiently, the member may be separated from the supports. The slots on the outersides of the brackets c may be open ended so that when the member b is in the innermost position the heads of the screws can take a position above the corners of these slots and thereby lock the member in position, as shown in Fig. 5, and the cover of the box can be formed so that it cannot be closed unless the screws are in this locking-position. Binding during sliding can be avoided by pivotting the brackets c to the member b. Specifications 221,055 and 221,056 are referred to.

Addition to 313,305, [Class 141, Wearing apparel]. [Class 141.] The invention described and claimed in the parent Specification is modified by arranging the reinforcing metal or other elements E in pockets D<1> formed between the two layers A, B, of fabric or other flexible material, thereby obviating the provision of anchoring strips. The pockets may be formed in various ways. In one construction, a strip of fabric is doubled and its ends sewn together. In the construction shown, a flattened tube D is woven with the two plies woven together at D<2>. Stitching, such as C<2>, is used to unite the pocket to the two outer layers of fabirc. The metal plate E is perforated at E<1>, E<2> for eyelets F which pass therethrough and through the fabric of the outer layers and the pocket, being clenched against the outer surfaces, as shown. In another construction, the pockets are arranged in a continuous strip woven in part, in part double to form pockets, and in part interwoven. The invention is applicable to aeronautical harness, waterproof sheets, rick clothes, tents, awnings. and other woven fabric constructions.

Catalysts specified are benzoylperoxide, aluminium trichloride and boron trifluoride.  In Examples (1) triethylvinylsilane was heated for 6 hours with diethylvinyl-phosphine oxide and benzoyl peroxide at 85 DEG C. to yield a colourless elastomer, and (2) divinyldiethyl-silane was similarly reacted with methylphosphonyl-chloride and AlCl3.  Uses: as high heat-stable insulating materials and lubricants or lubricating greases, with or without known lubricants; for the production of elastomers and resins for making formed objects or fibrous materials.

Title: Improvements in type bar actuating mechanism for typewriters
IPC: C07D215/12
Filed: 1957-05-14
Abstract: 848,015. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 14, 1957 [May 15, 1956], No. 15277/57. Class 100(4) In a type lever actuating mechanism when a key lever 10, Fig. 1, is depressed a projection 10a strikes a flange 26d and pivots a member 26 anti-clockwise about a stud 27 so that a shoulder 26c, Fig. 2, slides downwardly along an ear 16b, Fig. 1, until the member 26 is free to move to the left urged by a spring 28. Cam surface 26f now engages the ear 16b, thus the member 26 is cammed anti-clockwise as it moves to the left causing a flange 26e to engage a tail piece 20c on a cam element 20 to pivot the latter clockwise about a stud 19 until serrated face 20b contacts a power roller. 24. Roller 24 drives cam element 20 clockwise to push the stud 19 to the right and moves cam lever 16 clockwise on a pivot 34 and turns type lever 11 about pivot 15, through link 17, to engage platen 18. As cam 20 turns, a member 38 engages the flange 26e and slides the member 26 back to the right against the spring 28 until it is latched in position again by engagement of ear 16b with shoulder 26c. Movement of the cam 20 is arrested when tail 20c hits a bar 30. Cam lever 16 continues under its momentum to disengage the cam 20 from the power roller and return it to its home position under action of spring 21. The rest of the action is returned by spring 40.

Abstract: 718,184. Lapping. NATIONAL RESEARCH & DEVELOPMENT CORPORATION. June 19, 1952, [June 28, 1951.] No. 15397/51. Class 60. In a lapping machine comprising upper and lower lap elements between which a thin sheet is disposed as a work holder for work pieces positioned for engagement by the opposing surfaces of the lap elements, the upper lap element is mounted so as to be capable of a combined slight horizontal and vertical movement while operating on the work pieces. A machine particularly for lapping quartz crystal plates for high frequency oscillators comprises a lower lap plate or ring 2, Fig. 2, secured, e.g. by screws, to a base 5; an upper lap plate or ring 1 rests on work pieces 6 supported in a circularly arranged series of apertures in a work holder comprising a thin circular disc 7 disposed horizontally between the lap plates 1, 2. The disc 7 has a central boss 8 in which is mounted a pin 9 secured to an eccentric disc 10 on a driving shaft 11 extending vertically through a central aperture 3 in the upper lap plate 1. The upper lap plate 1 is disposed with play in a central aperture 14 of a stationary annular plate 15 supported by pillars from the base 5. During operation the upper lap plate 1 slowly rolls round the inner periphery 14 of the restraining plate 15 under the drag action of the work pieces 6, thus allowing the upper lap plate a high degree of freedom to float on the work pieces. In a modification, a fixed restraining disc 17 Fig. 4 is disposed with play in the central circular aperture 3 of the upper lap plate 1. The disc 17 is supported from a beam 18 mounted by pillars 19 on the base 5; the shaft 11 extends through a central aperture 20 and the lower lap plate 2 and through the base 5. In both embodiments, the upper lap plate 1 is preferably provided with one or more apertures through which abrasive material is supplied to the lap faces; a suspension of fine abrasive powder in oil or water may be used.

Convention date, Oct. 4, 1932. [Class 97 (iii).] In a golf club having a head of conventional face outline, the weight of the material of the head is so distributed that the turning moments of the masses are equalized about an imaginary axis c<1>-c<1> Figs. 7 and 9, that intersects the shaft axis at the grip and crosses the club head in a substantially central zone of its hitting place. To obtain this distribution of the mass of the head, the heel of the head is made lighter than usual and/or weighting material 17, Fig. 7, or 24, Fig. 9, is attached to or inserted in the toe. The position of the axis c<1>-c<1> of a club is ascertained by the device shown in Fig. 2, and comprising a base 5 provided at one end with a longitudinal knife-edge 9 and at the other with an adjustable slide 7. The club is supported in the device with its head resting on the upper tacky surface of a plate 6 mounted in the knife-edge and with its grip portion resting in a bearing 12 that is pivotally mounted on the slide and permits free rotation of the club about the apex of the knife-edge. The head is adjusted laterally of the plate until the latter balances, when the position of the axis c<1>-c<1> may be marked on the head by a scribe 22 constrained to move in a path parallel to the knife-edge.

[Class 98 (i)] To prevent fogging at the edges of a roll-film when loading a fresh spool into a camera a rigid flap or shield is hinged to one edge of the spool chamber so that it substantially closes the open side of the spool chamber, a narrow slit being left through which the film and its backing can pass. As shown in Fig. 1, the camera body 10 has the shields 18 hinged at 19 to the side of the spool chamber 12, the shields being curved to the contour of the spools 13 and the film passing through the slot between the end of the shield and the roller 15. In the form shown in Fig. 3, the shields 28 are flat and are hinged to the edge of the spool chambers 22 by flexible strips 29. In the closed position, the shields 28 rest on ledges formed along the side edges of the camera body. The camera is closed by the hinged back cover 21. The shields may serve as bearings for the end discs of spools which have no centre pivot. Reference is made to cameras having flexible curtains adapted to lie over the film spools.
