Title: Improvements in parallel vices, chucks and similar clamping devices
IPC: B25B1/24
Filed: 1929-05-16
Abstract: 329,168. Friedrich, B. May 16, 1929. Work-holders; chucks.-Vices, chucks, &c. in which the work is clamped and simultaneously forced down on the bed have rotatable or tiltable members mounted on the pressure jaws which act to depress the jaws when they are rotated or tilted by moving the jaws forward. The rotatable member b works in a cylindrical recess c in the jaw member d and has an angular recess engaged by the bevelled edge e of the jaw a. When the jaw member d is actuated to grip the work the pressure of the edge e of the jaw a against the edge f of the recess in the rotary member b rotates the later, causing the other edge g of the recess in the rotary member to press down on the edge k of the jaw a and force the work down on the bed m. The modification shown in Fig. 2 comprises also a tilting member n of prismatic section acting between the shoulder o and projection p. In another modification, Fig. 3, with tilting member only this member n has a wedge shaped projection r which engages an angular recess q in the jaw a when the tilting member has almost reached limiting position, thereby giving a feel of greater resistance to the vice screw when the work is properly clamped. Fig. 7 shows another similar modification wherein a projection r on the tilting member n coacts with an inclined shoulder z on the jaw a, whilst Fig. 8 shows a tilting member n of L-shape coacting with the corners i, h of the bevelled edge e. Lifting of the jaw member is prevented by ribs t thereon or on a part s connected thereto engaging under the bed v, guide bars x being interposed between the part s and the upper side y of the bed and pressed down on to the bed by screws u.
Patent GB-144653-A (GB)
Title: Improvement in piston rings
IPC: F16J9/20
Filed: 1920-06-07
Abstract: 144,653. Norwood, J. E. Aug. 14, 1918, [Convention date]. Piston packing.-A pistonpacking ring 5 is formed with an oil-retaining groove, having one side at right-angles to the cylinder wall and the other inclined and forming a sharp edge 7 of the same diameter as the wearing surface of the ring. The groove prevents the passage of oil to the combustion chamber and forms a liquid seal. During the downward movement of the piston, the ring 5 lifts and oil passes from the packing- r.ing groove 4 by passages 10 to the interior of the piston. A ring 9, situated in a groove at the bottom of the groove 4, presses on the back of the ring 5 and prevents oil from passing round it. Any oil which passes the ring 9 is led to the interior of the piston by passages 11. There may be more than one ring 5 and the oil-collecting rings may be separate from the packing-rings which in that case are backed by rings 9. Two oil-collecting rings may be arranged in a single groove, with their scraping edges facing in opposite directions, the rings being backed by a single ring 9. The top packing-ring 5 may be formed with a similar scraping edge 7, facing towards the combustion chamber, for preventing condensed fuel from passing to the crank chamber.
Patent GB-183978-A (GB)
Title: Improvements in and relating to electric switch operating mechanism
IPC: H01H3/30
Filed: 1921-06-03
Abstract: 183,978. British Thomson - Houston Co., Ltd., (General Electric Co.). June 3, 1921. Switches, quick-action; electric motor actuation.- A motor-driven switch has an auxiliary switch, which de-energizes the motor when the main switch is closed, and is cushioned to prevent damage from shock. Fig. 1 illustrates in the closed position the mechanism of a switch of the usual oil type connected to the link 10. The motor 13 drives through gearing a sector 18, loose on the shaft 12 and carrying a pin 25 which engages one end of a spring 21. The other end 26 engages the end of a toggle-link 22, pivoted to a toggle arm 28, loose on the shaft 12, and also to another togglelink 23 pivoted to a crank 24 rigidly mounted on shaft 12. Also pivoted to the link 22 is a spring-controlled shaft 34 carrying a pawl 33, which engages a catch 32 on the link 23 to hold the toggle set. An extension 39 to the arm 28 engages a member 38 to hold the switch closed. To trip the switch, the member 80 depresses the arm 35, the pawl 33 moves clear of its catch 32. the weight of the switch parts, or a spring attached thereto, rotates the shaft 12 and crank 24, and the toggle collapses as shown in Fig. 2. As the crank 24 rotates, a pin 43 thereon engages the end 42 of the member 38, and frees the member 39, which assumes the position shown in Fig. 3, the springs 30 at the same time re-setting the toggle. When the member 38 thus moves, an integral arm 62 thereof moves also, and, by means of a slot 60, a link 61 slides along a pin 58 in a spring- urged lever 55 on a shaft 54, which carries a switch 51. The fall of the member 39 then rotates a lever 65 free of a stop 64, and spring 56 then rotates the shaft 54 to close the switch 51 ready for the next operation of the motor. As the member 62 moves, it strikes a pin 76 to move a pawl 71 clear of a detent 70 on the sector 18, allowing the latter to be moved when necessary to close the switch, Fig. 3. To close the switch, the motor circuit is closed and the motor moves the toggles 22, 23, arm 28, crank 24, and shaft 12 all together to the position shown in Fig. 1. When the member 39 rises sufficiently, the spring 44 moves the arm 38 to lock it. At the same time the arm 62 opens the switch 51 and de-energizes the motor, the arm 65 is moved by spring 67 to lock the switch 51. The spring 21 then acts to cushion the motion of the moving parts and restore them to their original positions.

Title: Dialdehyde polysaccharide-acrylamide derivatives
IPC: D21H19/54
Filed: 1961-04-28
Abstract: Dialdehyde polysaccharides are converted to acrylamidyl derivatives by reaction with acrylamide in presence of an acidic catalyst. Reaction may be effected by adding the catalyst, e.g. aqueous sulphuric acid, to a stirred slurry of the dialdehyde and a solution of acrylamide in an aqueous or non-aqueous solvent, such as methanol, ethylene glycol monomethyl ether, or mixtures of the latter with water.  The proportion of catalyst is preferably 0,3-0,7% by weight of the reaction mixture.  The nature of the product, i.e. whether predominantly the mono- or di-acrylamidyl derivative, is dependent on reaction conditions and the molar ratio of acrylamide to dialdehyde polymer units, generally 1-4 to 1.  With the lower ratios, non-aqueous reaction media are preferred in order to minimize side-reactions.  The acrylamidyl derivatives, recovered as solids by filtration or centrifugation, are polyfunctional, and may have wide application as gels and dispersions for treating paper, textiles and leather.  They may be polymerized by heat and pressure, and may be copolymerized to yield hard, thermosetting resins.  Examples relate to the acrylamidylation of dialdehyde starch.  The dialdehyde polysaccharides used as starting materials may be obtained by periodate oxidation of, for example, celluloses, starches, inulin and algins.  U.S.A. Specification 2,713,553 is referred to.
