Title: Improvements in or relating to feeding mechanisms
IPC: B42C19/08
Filed: 1951-09-04
Abstract: 714,512. Feeding books and like articles from stacks. SMYTH-HORNE, Ltd., and TAYLOR, H. W. Sept. 4. 1952 LSept. 4, 1951], No. 20856/51. Class 117 [Also in Group XXX] A feeding mechanism which aligns and feeds articles, e.g. books to bookbinding machinery, comprises two pushers 20, 21, Fig. 1, arranged for reciprocating movement in paths at right angles to one another over a platform 17, the pusher 20 moving an article against a guide member 24 and then remaining stationary while the pusher 21 moves the article through the guide means formed by the pusher 20 and the guide 24. The pusher 20, Fig. 3, is a flat plate with a downwardly extending flange 22 at its front end which moves through a hopper 23 containing a pile of books and removes the bottom book therefrom. The pusher is connected by a vertically adjustable member 67 to a carriage 64 which slides on a rod 65. A pin 66, which can be secured in any position in a slot on the underside of the carriage, connects the carriage to the slotted upper end of a member 62 pivoted to the frame of the machine. This member is connected by a telescopic link 61a, 61b, the parts of which are held together by a spring-loaded ball catch 61c, to a pivoted member 57. A roller 59 on the member 57 is held by a spring in contact with a cam 37. The pusher 21, Fig. 2, is attached to a rod 48 which is mounted adjustably in the depending part 47 of a reciprocating carriage 43. The carriage is connected by a pin 42 to the slotted upper end of a pivoted member 38 which is rocked by a rotary cam 31. This cam is so shaped that the pusher 21 first makes a short movement to push a book against three pins 25 which project above the platform. The pusher is then halted momentarily while the pins are retracted below the platform and then its movement is resumed to push the book on to the conveyer 19 which feeds the bookbinding machinery. The lower ends of the pins are connected by a rod 55 which is engaged by the notched end of a pivoted lever 50. This lever is rocked by a cam 32. The cams 31, 32, 37 are driven by the conveyer 19.

Filed: 1946-07-12
Abstract: 614,373. Batteries. HYMAN, H. July 12, 1946, No. 20930. [Class 53] A dry cell having a zinc cup 12 surrounded by an absorbent wrapping 30 is provided with a closing seal 34 and a lower seal 22 separated by a space 28 and a washer 24. A water-proof jacket 38 surrounds the cell and is separated by a small space from the wrapping 30. Gases and liquids evolved from the cell under pressure can pass through or round the seal 22 and between the top of the cup 12 and seal 34 and so make contact with the wrapping 30 in which the liquids are absorbed. Liquids forced through punctures in the zinc cup are brought into direct contact with the absorbent wrapping. The bottom of the cell is closed by a metal cup 32 which makes contact with the zinc cup 12 and forms one terminal of the cell.

Title: Improved process for the manufacture of composite materials, for example, moulded laminated structures and articles of manufacture produced thereby
IPC: C04B26/12
Filed: 1943-12-29
Abstract: In the production of composite materials such as moulded p  laminated structures, glass fibres having a diameter of 0.002 inch or less are pre-coated with an oil-modified phenolaldehyde resin and are then bonded with a phenol-formaldehyde resin.  The fibres may be used in the form of a felt, or a woven, knitted or braided fabric made from continuous filament glass yarn.  Staple glass fibres may be included. The fabrics may contain an amylaceous material such as starch customarily incorporated in the yarns in small quantity to facilitate weaving or knitting.  The pre-coated fabric is coated by dipping once or repeatedly in a solution of the bonding phenol-formaldehyde resin, which may be the same as the pre-coating resin, and is dried after each dip.  The coated fabric may be superposed in layers to form a laminated material, or wound into rod form, and moulded under heat and pressure.  The oil-modified phenol-aldehyde resin may be prepared from phenol, cresol or xylenol, formaldehyde, and tung or oiticica oil, and applied as a toluene solution, which may contain a plasticiser such as diamyl or dibutyl phthalate, or tricresyl phosphate.  The laminated materials may be used for aeroplane propellers or structural parts, and reaction vessels, and the rods as tie-rods for circuit-breakers.

A circular clamp has a strap 2, the end portions of which are reinforced by strap portions 4 and to the reinforced end portions, lugs 6 are rigidly secured and to one of the lugs a bolt 18 is pivoted by means of a trunnion (16), the axis of which is at right angles to the axis of the bolt the bolt being engageable with the other lug and a nut 20 being provided for tightening the strap. In a modification the strap is in two or more parts each part being provided with the reinforced end portions to which a said lug is rigidly secured and one lug of each end portion carries a pivotally mounted bolt, as described <SP>/</SP> above, the bolt being engageable with the non bolt carrying lug of the other or one of the other straps. In the constructions shown a washer 22 is interposed between the or each nut and the corresponding lug. The reinforcing strap portions 4 are riveted to the strap 2 and the lugs are riveted between the strap portions 4 and the strap 2. The strap 2 carries a plurality of stainless steel segments 30 which are substantially U shaped in cross section and which are attached by rivets to the strap. The segments 30 are joined together by stainless steel links 32 and a U shaped link is pivoted to the or each trunnion (16) for the bolt or bolts 18, the U shaped link in use extending parallel to the bolt with the end portion of the bolt passing through a hole in the base of the link; the trunnion (16) passes through slots in the limbs of the link. The links 32 and 26 are intended to act as safety means should the strap or the bolt break. To prevent the link 26 becoming detached from the upper lug 6 in the event of the bolt breaking the link is formed with projections and the lug with grooves or vice versa.
