IPC: C06F5/00
Filed: 1929-04-25
Abstract: 329,796. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). April 25, 1929. Lighting by frictional devices. - Composition rods which may be repeatedly ignited and extinguished are used in pyrophoric igniters in place of petrol. The rods are composed mainly of a combustible organic mass, such as nitrified cellulose or derivatives, viscose &c., and an igniting material such as phosphorus, sulphur, sesquisulphide of phosphorus, antimony sulphide, lead thiosulphate, &c. To impart properties such as improved combustibility and responsiveness to moulding, camphor, naphthalene, esters of phosphoric acid, phenols, acetone, teramine of hexamethylene or other similar substances may be embodied. For supplying oxygen, potassium chlorate, nitrate or bichromate, ned lead, peroxide or nitrate of lead, pyrolusite and plumbate of calcium are suggested. Hardness may be imparted by formaldehyde products and fillers, organic or inorganic, may be added. Pumice, glass powder, carborundum, kieselguhr or powdered quartz, oxalate of ammonia, metal cyanides, &c. may also be added.

Title: Improvements in and relating to electrically insulated copper conductors
IPC: B21D53/58
Filed: 1932-05-05
Abstract: Copper electrical conductors are covered with an insulating layer of basic phosphates, acetates, borates, or carbonates, or mixtures thereof.  To produce the layer the copper is treated in a bath in which it comes into contact with the acid, the salt of which is to form the insulating layer.  The coating layer is dried in air and subsequently heat treated.  Previous to heating fillers such as asbestos or quartz or mica powder are applied to the coating and are incorporated with it in heating The asbestos may be wound on the wire before treating in the bath.  Specification 365,422 is referred to.

Title: Improvements relating to the treatment of articles with volatile organic solvents
IPC: C23G5/04
Filed: 1936-05-08
Abstract: <PICT:0466443/III/1> <PICT:0466443/III/2> Metal and other articles, including bulky silk lamp shades, leather gloves and other goods requiring brushing or handling, are cleaned with a volatile organic solvent preferably in the cold, in one or more vessels, by dipping, spraying, brushing, &c., and are then placed in or above a separate open vessel and dried whilst solvent vapours are withdrawn from the lower part of the vessel.  When a heated solvent is used, a cooling device is provided for condensing the hot vapours.  Solvents specified are trichlorethylene, perchlorethylene, carbon tetrachloride, benzine, benzene.  As shown in Fig. 1, dipping and drying compartments 5, 6 in a container 1 are separated by a partition 2 which is lower than the walls of the container, and the heavy vapours passing through a down-pipe 7 leading from the bottom of the compartment 6 to the outer air, and cause a down-draught through the compartment.  In modifications, the apparatus comprises two dipping compartments and a suction fan connected with the drying compartment, Fig. 2 (not shown), a drying compartment arranged above the dipping compartment and separated from it by spring flaps, Fig. 3 (not shown), and two dipping compartments and two drying grids, all arranged within a container, and a fan drawing vapour and air from the bottom of the container and delivering it through a tower packed with active charcoal from which the solvent may be recovered by steaming.  As shown in Fig. 5, a drying grid 33 for articles A is arranged over a chamber 34 connected with a suction fan 35, and a hood 37 with window 38 is arranged over the grid and the dipping chamber 32. An opening 39 being left for the operator's use.  This opening may be closed by a door 40 to avoid escape of solvent when not in use. Specification 299,650, [Class 91], is referred to.

Title: Improvements in or relating to apparatus for use in changing speed in motor cars, or the like
Filed: 1922-05-09
Abstract: 179,940. Stoutz, R. de. May 9, 1921, [Convention date]. Controlling-apparatus, arrangements of foot and transmission gear in conjunction with; controlling different functions by same handle or lever; interlocking and guardinq against wrong movements and the like.-Comprises means for facilitating gear-changing in which, in changing from a higher to a lower speed, the gear-box shaft is temporarily driven, either through the main or an auxiliary clutch and is released from the drive by the change-speed gear lever as it is moved from the " neutral" to the new gearposition. In the construction shown the main clutch 1, 2 is operated in the usual manner, in changing from a lower to a higher speed, by a pedal 5 acting through a tubular shaft 6, an arm 7, link 8 and lever 9, the pivot end 9<a> of the lever abutting against a stop 43. In " changing down" pedals 5, 11 are depressed, the action of the latter being to transfer the abutment of the lever 9 to a. notch 44 on an arm controlled by the gear lever 31 through a recessed disc 32 and a roller arm 46. The clutch is disengaged as before, but when the gear lever is moved to " nuetral " the roller 47 falls into the recess 48 and the abutment 44 moves so allowing the clutch to re-engage. As the gearlever is moved to its new gear-position the roller is forced out of the recess and the clutch is disengaged again until the pedals are released. The main clutch may be automatically re-engaged by the final movement of the gear-lever into its new gear-position, even while the pedals 5, 11 are still depressed. The accelerator pedal may be coupled to the auxiliary pedal 11 so as to be operated by it. Modifications are described in which (1) an auxiliary clutch is operated by the pedal 11 and the gear-lever, and (2) the main clutch is engaged by two separate springs, the auxiliary pedal 11 acting on one only of these, so that when this pedal is used the clutch is not completely disengaged until the gear-lever is moved from " neutral to the new gear-position. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also constructions in which (1) the main clutch is provided with two clutching surfaces, and is controlled by the two pedals without any control by the gear-lever; and (2; the auxiliary pedal is interlocked with the gear-lever, so that the pedal cannot be fully depressed until the lever is in " neutral" and thelever cannot be moved from " neutral " until the pedal has been partly released. This subjectmatter does not appear in the Specification as accepted.

Filed: 1972-03-22
Abstract: 1380821 Automatic control MITSUBISHI JUKOGYO KK 22 March 1972 13479/72 Heading G3N A positioning operation is confirmed by a circuit comprising comparator-amplifiers comparing instruction signals with actual position signals, to derive error signals which are processed in comparators to provide upper and lower-limit output signals which are fed to an AND-gate, the output of which is applied to a pulse-discrimination circuit sending out a positioning-operation complete signal when the AND-gate output equals a predetermined period of time. As shown, tri-axial instruction voltages Or from a programme unit and axes feedback voltages F#, indicative of the actual position of an arm of an industrial robot are applied to the inputs of comparator-amplifiers 1. The derived error voltages are fed to associated comparators 2, 3 to which are applied upper and lower limit reference voltages from a positive voltage generator 4 and a negative voltage generator 5 respectively. The generators provide '1' outputs, when the errors are below the reference values, which are applied to an AND circuit 6 which provides a '1' output when the arm is at the programmed position. When the duration of the 1 output exceeds a time set by a pulse-discriminating circuit 7, a signal is initiated to allow the robot to proceed with the next programmed operation. In a modification, for multi-axis control, the maximum and minimum detecting circuits receive all the error voltages and select the highest and lowest of the error voltages for transmission to the comparators.
