Title: Improvements in thermal responsive switches
IPC: H01H71/20
Filed: 1937-02-19
Abstract: 474,563. Automatic circuit breakers. GENERAL MOTORS CORPORATION. Feb. 19, 1937, No. 4995. Convention date, Oct. 21, 1936. [Class 38 (v)] A thermal circuit-breaker comprises contact springs 20, 22 biassed to the position shown and having side lugs 41, 43 extending into apertures 74, 76 in a manually operable resetting slide 70 which when pushed to the left caused the hooked end 32 of spring 20 to engage with a ratchet wheel 50 normally held by fusible material. During this operation, the disposition of the apertures 74, 76 causes the contacts 28, 30 to remain separated, but when the slide 70 is released it is moved to the right by the contact spring 22 and contact is made. This gives a trip-free arrangement, the contact spring 20 being released on overheating of the fusible material holding the ratchet 50 which may be effected by the heat conducted from a dynamo electric machine or by means of a series resistance (not shown). In a modification, the ratchet wheel is carried by one of the contact springs and engages a fixed pawl.

Title: Synthetic fibrous filter material for gas filters
Inventor: AUCKLAND JOHN RAYMOND
IPC: B01D39/18
Filed: 1963-02-07
Abstract: A fibrous filter material for gas filtration purposes consists of a mixture of secondary acetate fibres of a denier between 2 and 5 with fine viscose fibres of a denier between 1 and 4, the secondary acetate fibres constituting from 50% to 90% by weight of the mixture. Preferably at least the secondary acetate fibres are mutually bonded by using a suitable plasticizer or a resin binder applied by spray or in the form of a powder or foam.  The plasticizer or resin binder is usually applied during the scutching process and bonding is effected after carding when the matrix of mixed fibres is passed through a curing oven.  Both types of fibre may be bonded and in this case a suitable adhesive is applied between the cross-folding stage and entry to an oven used for curing and/or drying.  Fine gauze backing may be applied to opposite faces of the material in web form and this can be bonded to the material immediately prior to the curing and/or drying process or it may be applied separately during the manufacture of a filter element from the wadding.  Both types of fibre can be bulk processed for fire resistance and viscose fibres can be bulk processed for fungus resistance, secondary acetate fibres being intrinsically fungus resistant.

Title: Method and device for striking out the waste or parts to be used from punched sheet workpieces
IPC: B26D7/18
Filed: 1959-02-13
Abstract: 897,026. Removing waste &c. from punched sheet workpieces. SCHROTER, F. Feb. 13, 1959 [Feb. 22, 1958], No. 5181/59. Class 31 (1). A method of striking out the waste or parts to be used from punched sheet workpieces is characterized in that the parts to be struck out are each gripped on both sides within the region of an aperture in a template on which the workpiece is brought to bear, and whilst still gripped are each struck out by being moved through the said aperture, released while out of the plane of the template and then removed. Apparatus for carrying out the method comprises a template 13 for supporting the punched sheet workpiece 12, the template being formed with apertures 16 corresponding to the outlines of the parts 17 to be struck out, and pairs of pin-like rams 18, 27 movable towards and away from the workpiece. Each ram 18 is spring-urged and mounted in a bracket 20 rotatable about a member 21 which is slidably and clampably mounted on a crossmember 22. Similarly, each ram 27 is mounted in a bracket 28 rotatable about a member 29 slidably and clampably mounted on a cross-member 30. The ends of the cross-members are provided with teeth which engage rack teeth 38, 39 on longitudinal members 26, 34. The rack teeth 38, 39 are provided with marks so that by providing separate longitudinal members having similarly-marked rack teeth, the cross-members and associated rams can be set up outside the apparatus. Each member 29 has a spring- urged member 42 for clamping the workpiece against the template. The control of the members 26, 34 and hence of the cross-members and associated rams is derived from the drive movement of the punching tool carrier 2 by means 49, 51, 53 and crank drives 56, 57, 60, 61. The tool carrier 2 co-operates with a stationary tool carrier 1. The workpiece is fed intermittently by means of gripper carriages 5, Fig. 1, movable along rails 4 and carrying gripper rods 6, each carriage being formed with a rack 7 to engage cam-controlled toothed segments 8, 9, 10, 11 in the feeding, punching, striking-out and laying-out stations respectively. In operation, the rams 18 are moved upwardly to engage the workpiece parts to be struck out, as shown in Fig. 3. The corresponding rams 27 are then moved downwardly to engage the other side of the workpiece parts, as shown in Fig. 4, and at the same time, the members 42 clamp the workpiece. The rams 18, 27 are then moved downwardly together, as shown in Fig. 5, to strike out the workpiece parts and guide them along a path 48-48. The workpiece parts are released, as shown in Fig. 6, by moving the ram 18 downwardly and at the same time moving the ram 27 upwardly. The struck-out workpieces descend by gravity and are removed in known manner or by compressed air, suction or mechanical means. Specification 827,872 is referred to.

Title: Improvements in and relating to an automatically variable change speed gear device
IPC: F16H33/08
Filed: 1934-02-17
Abstract: 422,368. Variable speed gearing. BERLIN. D. W., Rasunda, Sweden. Feb. 17, 1934, No. 5310. Convention date, Dec. 7, 1933. [Class 80 (ii)] [See also Group XXXIV] Variable-speed gearing automatically variable with the load comprises rotary and centrifugal masses 3, Fig. 2, which produce alternately positive and negative turning impulses. The positive impulses are transmitted directly to the driven shaft 7 by a primary one-way clutch 8. The negative impulses are transmitted through a further primary one-way clutch 10, a reversing train 9, 11, 12, and a secondary one-way clutch 13 so as to drive the shaft 7 in the same direction as the positive impulses. The masses 3 which are rotated by a link connection 4, Fig. 3, with a driving-drum 2 turn loosely upon eccentrics 6 to which the impulses are imparted. The eccentrics 6 are rigid with a sleeve 5 loose on the shaft 7 which sleeve has a flange 5<1>, Fig. 4, projecting between the two primary one-way clutches 8, 10. A one-way clutch at 29, Fig. 2, allows the driven shaft 7 to be braked by resistance on the driving- shaft 1. Insulating material such as lead may be interposed at 33 between the shaft bearings 30, 31, 32 and the casing 20 to eliminate noise. A brake 28 applied at the will of the operator to the wheel 9 produces an abutment so that the negative impulses react as forward impulses on the sleeve 5 and are returned as such to the driving-shaft. In Fig. 1, not shown, is an arrangement with a separate sliding-gear reversing-gear between the shaft 7 and a tail shaft. An arrangement is described with reference to Fig. 9, not shown, in which reversed driving is effected by reversing the positiveimpulse clutch 8, Fig. 2, and one of the clutches 10, 13 of the negative impulse train.

Abstract: 1,151,285. Automatic volume control. BENDIX CORP. 6 Feb., 1967 [3 March, 1966], No. 5605/67. Heading H4R. Variable attenuator comprises, as shown in Fig. 1, a resistor 10 through which the input signal at terminal 14 is fed to point 20. An amplifier 28 is connected to provide negative feedback around a loop including point 20 so that the signal level at point 20 is reduced in proportion to the gain around the feedback loop, which is controlled by varying the value of the variable resistance element 24. Fig. 3 shows an automatic volume control system in which the input signal is applied via a high impedance driving stage 64 to the point 88 to which is connected the feedback loop including transistor 90, the base of which is fed with signal via a potential divider consisting of resistor 96 and the impedance of diodes 106 and 108, which impedance is varied by the rectified output of amplifier 72 fed with the signal at point 88. The gain of the negative feedback loop is therefore controlled by the signal level at the output of amplifier 72 so as to tend to maintain that signal level constant. The diodes 106 and 108 may be replaced by the emitter collector path of a transistor whose base is fed with the rectified signal, Fig 3a (not shown). Zener diode 92 provides appropriate bias for transistor 90 so that it operates linearly.
