Title: Improvements in electrically driven clocks
IPC: G04C21/08
Filed: 1941-09-04
Abstract: 550,548. Clocks. DRUMMOND, C. T. Sept. 4, 1941, No. 11303. [Class 139] A striking mechanism for an electrically driven clock comprises a snail cam on the hour spindle, a serrated member movable radially with respect to the snail cam, a pawl-carrying device to co-operate with the serrated member, and a second cam operable to displace the pawl device prior to the striking period, to permit the member to fall on to the snail cam, and to return it at the period into engaging position thereby completing an electric circuit, thereby the pawl device is reciprocated to move the serrated member back to a predetermined position and to send, at each movement, an impulse to the striking mechanism. As shown in Fig. 1 ,a snail cam 4 making one, revolution every hour co-operates with a pivoted lever 5 to which is fixed a layer 18 of insulating material carrying a fixed retaining pawl 19 and a cover 22 to which is pivoted an actuating pawl 23, Fig. 5, having a limited amount of vertical movement. The cover 22 is formed with an eyelet 26 to which is attached one end of a chain 27 the other end of which is secured to a wire loop 28 on the armature 29 of an electromagnet 30 the energisation of which operates the striking hammer rod 31. The pawls 19, 23 co-operate with a serrated sleeve 13 fixed to a vertical rod 10. Below the sleeve 13 is a sleeve of insulating, material (not shown) on which is mounted a metal sleeve 16 with single serration slightly larger in diameter. The lower end of the rod 10 is arranged to co-operate with a snail cam 9 on the sleeve of the hour hand. The electromagnet 30 is arranged in circuit with the pawls 19, 23 and the sleeve 13. In operation shortly before the hour is reached the retaining pawl 19 is withdrawn to release the rod 10 which falls on to the snail cam 9. At the hour the lever 5 jumps off the snail cam 4 and causes the pawls to contact the sleeve 13 thereby completing the electric circuit. The energisation of the electromagnet 30 raises the striking hammer to hit the bell and the rod 10 is raised to the extent of one serration. The circuit is associated with a contact (not shown) that is closed momentarily as described in Specification 549,409 or Specification 550,549 so that the electromagnet is repeatedly energised and de-energised to raise the rod step by step until the serration on the sleeve 16 has been lifted whereupon the circuit is opened.. The number of strokes depends upon the position of the hour snail cam 9.

Title: Improvements in or relating to the manufacture of synthetic resin materials
Inventor: VARLET PIERRE PAUL WILLIAM
IPC: C08F263/06
Filed: 1961-03-28
Abstract: A deformable heat-hardenable synthetic resin material is made by polymerizing to a gelled state a composition comprising (a) a partially polymerized allyl ester, e.g. diallyl adipate or phthalate, (b) an ethylenically unsaturated copolymerizable monomer, e.g. methyl methacrylate, (c) a polymerization initiator, e.g. benzoyl peroxide, and (d) a polymerization activator comprising a mercaptan, e.g. allyl or lauryl mercaptan, and a reducing salt of a polyvalent metal, e.g. stannous chloride.  The partial polymerization of the allyl ester may be carried out with aid of ultra-violet light in the presence of benzoin or benzoylphenyl carbinol. The viscosity of the gel and the activity of the polyvalent metal salt may be controlled by dissolving the latter in a solvent, e.g. glycol, tetrahydrofurane, furfural, dioxane, or di-methylformamide. The resinous material, either before or after gelling, is used to coat or impregnate reinforcing materials, e.g. glass fibre, paper, or a metal sheet.ALSO:Glass fibre fabrics or paper are coated and/or impregnated with a heat-hardenable resinous material made by polymerizing to a gelled state a composition comprising (a) a partially polymerized allyl ester, e.g. diallyl adipate or phthalate, (b) an ethylenic monomer, e.g. methyl methacrylate, (c) a polymerization initiator, and (d) a polymerization activator comprising a mercaptan and a reducing salt of a polyvalent metal, e.g. stannous chloride.  The resinous material may be used either before or after gelling for impregnating or coating the reinforcing material.  The stickiness of the surfaces of sheets so-formed may be removed by contacting them with rollers or continuous belts impregnated with an accelerator, e.g. a tertiary amine.  The resulting sheets are hardened by heating.

Title: Improvements in or relating to methods of stabilizing fats and/or oils and the improved product resulting therefrom
IPC: C11B5/00
Filed: 1933-04-18
Abstract: Rancidity of oils and fats, e.g. cottonseed oil, lard and other shortening products, and cloudiness or seeding out of salad oils such as olive, peanut, and cottonseed, are inhibited by the addition of a small percentage of crude cottonseed oil.  The crude oil may first be deodorized without impairment of its antioxidant power, e.g. by blowing with steam, and for food products is preferably free from gossypol.  In examples, 1--5 per cent of crude hot-pressed cottonseed oil is added to lard, and 0,5--5,0 per cent to "winterized" cottonseed oil; the latter mixture may be deodorized e.g. by steam. The "winterized" p  cottonseed oil is obtained by treating the crude oil with caustic soda to remove free fatty acids and impurities causing colour, maintaining at a low temperature until the harder portions such as tristearin and tri-palmitin crystallize out, filtering, and deodorizing.

Title: Improvements in infinitely variable change speed gears
IPC: F16H3/42
Filed: 1958-04-11
Abstract: 860,775. Expanding-wheel gear. RATHE, C. April 11, 1958 [April 17, 1957], No. 11552/58. Class 80 (2). Expanding-wheel gearing comprises a driving (or driven) shaft 3 carrying two gears 5 meshing idle gears 10 carried on a shaft 9 at the ends of the arms of a U-shaped support 8 rocking about the axis of the shaft 3, the idle gears in turn meshing a pair of variable-diameter gears 12 on a driven (or driving) shaft 4. Each variable-diameter gear consists of individual teeth 14, Fig. 3, connected by a pair of flexible metal bands 13, projecting lugs 14a at one end of the teeth engaging a spiral groove 17 in a disc 16 and one of the teeth engaging at the other end with a radial ridge 15a on a disc 15. The disc 16 can turn relatively to the shaft 4, while the disc 15 is fast thereon. Relative rotation between a disc 16 and the disc 15 causes the associated band of teeth 14 either to move out to a maximum diameter, when its two ends are 180 degrees apart, or to move in to a minimum diameter when its two ends abut. A control shaft 18 is driven from the shaft 4 through a gear pair 19, 20, and carries the bevel planet pinions 25 of a differential gear, the sun gears 22 of which are fast with gears 21 meshing the spirallygrooved discs 16. Relative rotation of the spirally-grooved discs 16 and the radiallygrooved disc 15, to adjust the diameters of the gears 12 and vary the velocity ratio, is effected by turning a handle 39 and a control shaft 32, Fig. 3, fast upon which is an arm 40 engaging a collar 42 secured to the shaft 4, thereby slidden axially to engage one or other of the spirally grooved discs 16 with an associated. brake disc 35. At the same time a nut 27, Fig. 2, which is constrained to rotate with one of the sun gears 21 by pins 28, is turned relatively to the control shaft 18 upon which it is threaded, so that it moves axially and thereby turns a bell-crank lever 30 to rock the U-shaped support 8 and adjust the separation of the shafts 4, 9. Correct meshing of the variable diameter gears 12 and the idle gears 10 is effected by three guide teeth 14<SP>1</SP>, Fig. 4, at the beginning of each band of teeth 14, which can cause axial sliding of the idle gears 10, plates 11 at each side of the gears 5 overlapping the idle gears 10 and constraining the gears 5 to move axially on helical splines 6 by which they are connected to the shaft 3, this axial movement accordingly turning the gears 5 on their shaft 3. The ratio established in the gear is indicated by a pointer 37 connected to the bell-crank lever 30 and moving over a scale 38.

Title: Improvements in or relating to pilger mill apparatus
Inventor: BROOKS CYRIL
IPC: B21B21/04
Filed: 1952-05-07
Abstract: 730,775. Rolling-mandrel carriages. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd. July 31, 1953 [May 7, 1952], No. 11587/52. Class 83 (4). In a pilger rolling mill the resilient means on the carriage 4, Fig. 1, for returning the work forward when freed by the gap in the rolls 10 comprises a fixed part such as a pneumatic cylinder 30, a first movable part such as a piston 32 carrying the mandrel 29 and one or more intermediate movable parts such as telescoped cylinders 31, the movable parts being successively arrested in their forward movements to reduce the shock on the carriage 4. The piston 32 is slidably mounted in a liquid container 39 on the carriage 4 and has a shoulder 38 which enters a cylindrical extension 40 in the container to provide a cushion to absorb the shock on arrest of its forward movement. The rear end of the piston 32 slides within the intermediate cylinder 31 which has a pocket 36 to provide a cushion for the end of the piston 32 when forced back by the rolls. Forward movement of the cylinder 31 is arrested by a pneumatic or hydraulic plunger 45 on the container 39. In operation the cylinder 31 and piston 32 initially forced back within the cylinder 30 are forced forward by the pressure in the cylinder 30 when the work is released by the rolls. The cylinder 31 is first arrested by the plunger 45 while the piston 32 continues to move until it is arrested by shoulder 38 engaging in the extension 40. The carriage is progressively fed by a hydraulic ram 5 and is withdrawn to strip the work from the mandrel by a hydraulic ram 6. The work is rotated through 90 degrees after each working stroke by a screw head 49 engaging a recess in the piston 32, the head being intermittently rotated during the backward stroke and returned in position by a ratchet 54 and wheel 52. In a modification the container 39 may be mounted on a forward extension of the cylinder 30 and may have a limited sliding movement on the carriage 4.
