Patent GB-261916-A (GB)
Abstract: 261,916. Marks, E. C. R., (Elliott-Fisher Co.). Nov. 28, 1925. Transfer-mechanism for totalizing-counters. The transfer-effecting member is pivotally mounted and is acted upon by a force passing through the pivot but normally remains in unstable equilibrium. By the passage of the transfer tooth the member is displaced to upset its equilibrium and is further moved by the force to effect the transfer. As applied to the computing- apparatus of an Elliott-Fisher machine the transfer actuating-member comprises a head 18 pivoted at 16 and provided with a trip finger 19 and two one-way pawls 25. An extension 22 of the head is pivotally connected at 46 to a lever 29 tending to turn clockwise by the action of a spring 43. At transfer the tripping lug 47 rocks the head in one or other direction to disturb the toggle formed by the head 18 and lever 29 so that the spring 43 can collapse the toggle and by means of one bf the pawls 24 effect the transfer. The pawls are shaped at 26 to serve in conjunction with the nose 24 to lock the higher wheel at the end of the stroke. A detent 31 bears against a. roller 30 at the end of lever 29 to assist in maintaining the toggle in alignment. Restoration of the transfer parts is effected by a pair of yokes 49 pivotally supported by shaft 16 and rocked by the subsequent movement of the carriage, a cam on which pushes in a rack 55 geared with the yokes in the manner shown.
Patent GB-670617-A (GB)
Title: Process of producing organosilicon compounds
IPC: C07F7/18
Filed: 1947-09-27
Abstract: Organo silicon compounds are prepared either by heating an alkyne with a silane having at least one Si-H bond at a temperature not above 425 DEG  C., or by heating an unsaturated hydrocarbon or a substituted unsaturated hydrocarbon with a silane having at least one Si-H band and having only alkoxy or hydrocarbon radicals attached to the silicon atom at a temperature not above 425 DEG  C.  By the term "unsaturated" is meant acetylenic, olefinic or cyclo-olefinic unsaturation.  The term "substituted unsaturated hydrocarbon" does not include a substituted alkyne.  The reactants may be heated at constant volume.  The preferred reaction temperature is not above 325 DEG  C. The reactants may be heated in the presence of a metal of the platinum group, e.g. platinum itself.  The partially chlorinated silanes, e.g. mono-, di- and tri-chlorosilane and mixtures thereof, and methyldichlorosilane, are preferred for reaction with the alkyne, and triethoxysilane may be reacted with the unsaturated hydrocarbons. Suitable unsaturated hydrocarbons are those having one or more double bonds such as the alkenes, dienes and alkynes, e.g. ethylene, propylene, n-octene cyclohexene, butadiene and acetylene.  Suitable substituted unsaturated hydrocarbons are vinyl chloride and glycerides of unsaturated fatty acids.  In example (1) acetylene is reacted with trichlorosilane to give vinyltrichlorosilane and 1,2-di-(trichlorosilyl) ethane; (2) ethylene and triethoxysilane are reacted to give ethyltriethoxysilane.  The Specification as open to inspection under Sect. 91 refers to the preparation of organo silicon compounds by heating an unsubstituted or substituted unsaturated hydrocarbon containing an ethylenic or acetylenic linkage with any silane having at least one Si-H bond at a temperature not above 425 DEG  C.  Many additional reactants, organosilicon products and examples are given.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specification 684,662.

Title: Improvements in or relating to snap-action electric switches
IPC: H01H33/64
Filed: 1937-09-28
Abstract: 503,021. Snap-action switches. COFFEEN, J. M. Sept. 28, 1937, No. 26242. Convention date, Dec. 12, 1936. [Class 38 (v)] In a snap-action switch a peripherally held diaphragm exerts a continuous reaction in ono direction to open the contacts, and is moved by an actuator which engages it at a position intermediate between its centre and periphery, snap action occurring in both directions. The two insulating cup-shaped parts 11 and 14 are bolted together to form a body 10 and to grip the dished diaphragm 38 around its periphery. A stud 50, riveted to the centre of the diaphragm 38 carries a plate 51 which, when the diaphragm 38 is curved upwards to its fullest extent, makes contact with a U-shaped plate 23 held in position by a screw 30, and a terminal 25 secured to the wall of the body. The diaphragm 38 is snapped downwards past the position of maximum opposing force by an actuating member 32 comprising a stud 33, and an inverted cup-shaped member 36 which engages the diaphragm midway between its centre and periphery, a sensitive action being thereby obtained. Contact is thus broken between the terminal 25 and a terminal 46 in contact with the diaphragm 38, and established between the latter and an annular disc 21 fixed to the terminal 16. The body members may be sealed together by cement 61 in channel 60 and the hermetically sealed contact chamber 12 thereby formed below the diaphragm, may be filled with an inert gas. The Specification also describes a modification in which the diaphragm operates a bell-crank lever which forms the common contact arm of a two-way switch with resilient stationary contacts.

Title: Improved machine for producing filled packages, particularly liquid-filled packages
IPC: B31B3/00
Filed: 1961-07-20
Abstract: 925,169. Seaming. FR. HESSER MASCHINENFABRIK A.G. July 20, 1961 [July 25, 1960], No. 26289/61. Class 42 (1). [Also in Group XVII] In a machine for forming, filling and closing containers (see Group XVII) a strip of cardboard lined with a plastics material is folded on a mandrel and sealed longitudinally, Figs. 2 and 3 (not shown), the tube so formed being cut into lengths by blades 31, 32 which travel laterally with the moving tube. The blades 31, 32 are mounted on arms 41, 42, respectively, the arm 42 being mounted on crank arms 33, 34 continuously driven from gear-wheels 38-40. The upper blade 31 is pivotally mounted and actuated by a cam 52 and roller 51 to cut the tube. A roller 43 running on a cam rail 44 keeps the lateral movement of the cutters straight. The coupling between the cranks 33, 34 and arm 42 is flexible, Fig. 7 (not shown). Welding mechanism.-Each tube is opened to a square cross-section before transfer to a mandrel 100 where it receives a bottom cover of thermoplastic material, e.g. polythene. Transfer is effected by grippers on the mandrel, Figs. 10, 11 (not shown), actuated through a rod 125, roller 126 and fixed cam ring 124. The mandrels 100 are mounted on a rotating drum 102 and are raised and lowered in a vertical plane by pivoted linkage under control of a roller 107 running in a fixed cam ring 105. In the raised position the container base is heat-sealed by a welding head 150 having a fixed headpiece 151 and heated jaws 152 which are moved diagonally inwards against the container base under control of a cam 163, Fig. 8, and roller 162. The jaws 152 are subject to the action of springs 156 through intermediate pivoted linkage having rollers 158 which bear against a sleeve 159 slidable on a rod 160. If the machine stops, a motor 174 is energized to raise a ring 170 which lifts the roller 162 and thereby removes the jaws 152 from contact with the container. When the welding is completed, the grippers on the mandrel 100 pull the container from the head 150. Compressed air may be blown through the headpiece 151 against the container base in order to aid its separation from the head 150 and for cooling. After the container is filled, a top cover is welded on in a rotating drum machine operated in a similar way, Fig. 19 (not shown), to that employed for welding the base.
