Title: Improvements in or relating to starter motors of internal combustion engines
IPC: H02H7/085
Filed: 1961-01-20
Abstract: 908,850. Starting prime movers. BOSCH G.m.b.H., ROBERT. Jan. 20, 1961 [Jan. 21, 1960], No. 2309/61. Class 38 (4). Overloading of a vehicle starter motor 10 is prevented by a relay contact 19 in a starter contactor operating circuit being operated by the volts drop across the starter motor field coil 12 or part thereof when the current in this has risen to 80% of the stalling current. Starter push button 20 is depressed together with a manually operated decompression valve 23, thus closing associated contact 22 against the action of a spring 21 and energizing the operating coil 17 of a starter contactor 13 which bridges contacts 15, 16 and thus energizes the starter motor 10 through its field coil 12. The operating coil 27 of an electromagnetic switch 26 is energized over contact 15 thus closing a switch contact 19 and energizing the contactor operating coil 17 in parallel with the decompression valve contacts 22. Once the starter motor commences to run, its operating current will decrease steeply, and when the motor has reached a certain speed, the decompression valve 23 is released, thus opening the contacts 22. Due to the coil 27 keeping the contact 19 closed, the starter motor will continue to run the engine until it has started and the push button 20 is released. If the decompression valve has been closed, thus opening the contacts 22 and the starter motor current rises abnormally due to unfavourable engine starting conditions prevailing, when the volts drop across the field coil 12 is arranged to open the contactor 19 by means of a coil 28 which overcomes the action of the coil 27 when the starter motor current reaches a value of 80% of the motor stalling current. The system also ensures that the starter motor cannot be operated unless the decompression valve 24 has been operated.

Title: Improvements relating to the electrical welding of chain links or the like
IPC: B21L3/02
Filed: 1921-01-19
Abstract: 166,104. Columbus McKinnon Chain Co., (Assignees of Stahl, F. E.). July 7, 1920, [Convention date]. Welding chains and rings; welded joints.-In a method of electrically welding chain links or the like, pressure is first applied to the links during heating to cause the ends to merge but not bulge, and then on withdrawal of the heating electrodes further pressure is applied to complete the weld, thus causing the ends to bulge, the joint being surrounded at the sides and exterior so as to confine the bulge to the interior so that a strong joint without any projecting parts is formed. The bulge may be large enough to act as a stud crossmember. In the form shown a chain D, which is mounted on a roller 18 intermittently rotated by an arm on a cam-shaft engaging a peg wheel 20 carried by the roll shaft, is fed between two pairs of movable heating electrodes 3, 4, 5, 6 which are carried by separate pivoted arms operated by levers 14, 13 from the cam-shaft, as described in Specification 137,748. Welding is effected by a pair of pushers 28, which are operated bv levers 29 and cams 32 on a shaft 23 geared to the cam-shaft. The ends of the levers are bifurcated at 34 to embrace the pushers and engage between collars 35 fixed to the pushers and collars 36 loosely mounted thereon, the collars 36 being separated by springs 38 from adjustable nuts 37 screwed on the pushers. During heating of the link, the levers 29 are operated to give a yielding pressure to the pushers through the springs, the pressure being limited by contact of the collars 35 with the ends of the levers. After withdrawing the electrodes, the levers are operated to press the ends of the link further together and form the bulge. In order to restrict the bulge to the interior of the link, the joint during this action is surrounded on its exterior and sides by a die 61 provided with integral or removable side portions 60. The die is laterally extended so that it overlaps the unheated portions of the link to prevent bending of the softened portion when the die is lowered. The die is removably mounted in a carrier 51 which is connected by a right and left-handed screwed connector 50 to a yoke 49 pivotally connected to a lever 43. The lever is pivoted at 44 to a yoke 45 rising from a shaft 46, and is operated by a cam 40. The carrier may slide in a box guide 63 secured to a bar 62 supported on the frame by rods 65. The alternate links may be welded by a second passage of the chain through the machine or by feeding the chain to a second similar machine.

Patent GB-345022-A (GB)
Title: Improvements in or relating to the treatment of textile materials and the products produced thereby
IPC: D06Q1/02
Filed: 1930-01-28
Abstract: A process for obtaining ornamental effects on mixed yarns composed both of fibres of cellulose acetate or other organic derivative of cellulose and fibres of another material, or on fabrics containing such mixed yarns comprises treating the yarns or fabrics with a reagent that causes greater shrinkage of the fibres not composed of the cellulose derivatives, the fibres so composed being thereby cockled.  The fibres mixed with the organic derivative of cellulose may be cotton, natural silk, artificial fibres of reconstituted cellulose, wool, &c.  The yarns may be produced by twisting together yarns, twisted or not, of filaments of the cellulose derivative with yarns spun from the other materials; by associating untwisted filaments of organic derivatives of cellulose with yarns spun from the other fibres; or by spinning together short lengths of the organic derivatives of cellulose with fibres of the other materials. The fabrics may be knitted or woven and be composed wholly of the mixed yarns or of those yarns together with other yarns.  The mixed yarns may alternate in any way with the other yarns in the warp, or weft, or both, and such alternation may be regular or such as to produce checks, stripes, or complicated designs.  The wool fibre component may be shrunk with water, in the finishing or scouring bath, by a soda solution, or by wetting and then drying slowly.  If it is desired to shrink the cotton constituent of the mixed fibres, caustic alkali may be used.  In the case of fabrics, the shrinking-agent may be applied over the whole surface, or locally in the form of a paste by brushing or spraying through stencils. The fabric or yarn may be dyed before, during, or after the shrinking treatment to obtain solid or cross-dyed effects.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of nitric acid for shrinking the cellulose derivative component of the yarns or fabrics.  This subject-matter does not appear in the Specification as accepted.

Abstract: 332,908. Gilbert, V. H., Johnson, A. H., and Radiovisor Parent, Ltd. Jan. 28, 1929. Light-sensitive cells.-A selenium cell 1 is connected in series with a fixed resistance 9 and a battery 10. A neon tube 2 is connected between the junction of the resistance 1, 9 and the grid of a thermionic valve 11, in the anode circuit of which is a relay 16. A grid leak 17 of the order of 10 megohms is connected as shown. Befoxe ionization takes place in the tube 2, the grid of the valve 11 is insulated and a large anode current flows. When the potential difference at the junction of the resistance 1, 9 due to the impressed current is sufficiently great, ionization takes place in the neon tube 2, impressing a high negative potential on the grid of the valve and consequently reducing the anode current to a low value. The resistance 9 consists of a second selenium cell kept under constant illumination. Changes of atmospheric temperatures then affect both cells equally and cause no change in the potential at their junction.
