Title: Improvements in or relating to apparatus for severing material
IPC: B21F99/00
Filed: 1942-06-17
Abstract: 558,122. Cutting strip material, wire &c. into lengths. KEEN, H. H. June 17, 1942, No. 8328. [Class 83 (iv)] Strip material, wire &c. is cut into equal lengths by a device that is rendered inoperative immediately after cutting, is reset when the resulting gap reaches ejector feed rolls and is again actuated when the oncoming stock enters three rolls. A belt 4 running over pulleys 3 one of which is driven, drives the feed rolls 8, 19 and 26 in such manner that slip occurs in the event of obstruction to the movement of the stock. Stock 5 is drawn from a coil 6 by the rolls 8 to which it is led by a guide 7 and from which it passes by guides 10, 12 to a guide 14 leading to the ejector feed rolls 19, 26. A section 13 of guide, interchangeable according to the length to be cut is held between the guides 12, 14 the plate 15 carrying the ejector rolls being adjustable in a slot 17 in the frame for this purpose. A cutter 11 operates between the guides 10, 12 as controlled by an electromagnet 32. The wire &c. 5 is fed past the cutter 11 as in Fig. 3 and passes between the rollers 20 and 19 depressing the arm 23 closing contacts 25 and opening contacts 24. Circuit from 36 through contacts 24 and coil 38 to line 37 closes a switch, with holding contacts 39 for the coil, and contacts 40 in the circuit of the magnet 32. When the contacts 25 are closed as above the magnet 32 is excited and the cutter severs the wire. An arm 35 then opens contacts 34 breaking the holding circuit and releasing the switch opening the contacts 39, 40. Whilst the blade obstructs the wire the rollers 8 slip stopping the feed whilst the severed piece is carried on by the rolls 19, 26 thus forming a gap between the severed ends. The magnet may be provided with an additional short circuited winding to make it more sluggish so that the cutter obstructs the wire for a longer period to cause a wider gap. When the gap reaches the roll 19 the roller 20 drops and the contacts 25 open whilst 24 close reestablishing the circuit through the coil 38 to close the switch and reset the device ready for a further cut as soon as the roller 20 is raised by the oncoming wire. In a modification for cutting very flexible strip the guides 14 are replaced by flat guides those between the rolls 19, 26 being slotted to pass an arm of a bell crank operating the contacts 24, 25 by contact with the end of the .strip. In this case also the rolls 8 may feed the material positively the guide 10 being arranged to allow the material to bend. The cutter is then given a rapid actuation and the rolls 19, 26 are driven yieldingly at a higher speed to eject the cut off piece rapidly and so cause the formation of the gap.

Title: Improvements in braking devices for trailer vehicles
IPC: B60T7/20
Filed: 1935-03-18
Abstract: 446,856. Trailer - vehicle brakes. KRUMBIEGEL, J. A., 6, Uferstrasse, Rosswein, Saxony, Germany. March 18, 1935, No. 8360. [Class 103 (i)] In brake mechanism for trailer vehicles of the kind in which the brakes are automatically applied by the closing in of the trailer relatively to the tractor vehicle, there is interposed in the brake transmission members means such as a sprmg whereby the brake may be applied by the driver independently of the automatic operation and also means such as a spring for taking up shocks so that the brake pressure may be gradually applied and may not be excessive. The pull-rod 2 sliding in the draw-bar or frame 7 is connected to the brakes by a telescopic member comprising relatively sliding tubes 8, 9 pivoted respectively at 19 to the pull-rod 2 and at 10 to the brake rod 12. A spring 20 seats on an abutment 24 secured in the part 8 and on a head 14 slidable in the part 8. The head 14 is secured to a rod 13 slidable in the end of the part 8 and provided with a pin 15 normally engaged by a lever 16 pivoted at 19 whereby the spring 20 is normally held compressed. A second spring 21 abuts on the head 14 and on a head 27 secured in the tubular part 9. The spring 21 surrounds a rod 25 slidable in the head 27. When the trailer closes in on the tractor a spring 4 disposed between an abutment 23 on the pull rod 2 and the part 3<1> of the draw-bar 7 is compressed and if the movement is sufficient, the brake is applied through the member 8, head 14, spring 21 and member 9, the spring being compressed and so preventing the application from being sudden. The brakes can be independently applied by the spring 20 by operating the lever 16, as by a cable extending to the driver's position, thereby disengaging the pin 15. The spring 20 is re-compressed by backward movement of the tractor. The springs may be replaced by a single-spring extending between the abutments 24, 27. The draw-bar 7 is supported at coupling height by the springs in the member 8, 9.

Title: Improvements in air operated automatic controller mechanisms
Inventor: GROUT JOHN ARTHUR MUNFORD
IPC: F16K31/126
Filed: 1947-03-28
Abstract: 699,011. Fluid-pressure servomotor-control systems. KENT, Ltd., G. March 24, 1948 [March 28, 1947], No. 8530/47. Class 135 An air-pressure controller mechanism of the integral and proportional, or integral, proportional and derivative type, has means for influencing the pilot valve, e.g., a nozzle controlling flapper, by a movement derived from the pressure in the integral bellows whereby the offset is maintained substantially constant at all sensitivity settings. A meter float 2 actuates, through one end 2A of a floating lever 1 and sensitivity adjusting link 5, a flapper 4 controlling a nozzle 3 fed with pressure air at 12 through a resistance 13, for controlling, e.g., a liquid level by a valve 11. The other end 2B of the lever 1 is moved through a link 19 and bellcrank 14, 18, by a bellows 6, one side of which; fed with air at 8, provides a proportional chamber, and the other side, fed through an integral resistance 9, provides an integral chamber. A derivative resistance 10 may be incorporated as shown. Normally when a prolonged error is counteracted, the meter-float detects a small offset in the controlled variable, which offset varies inversely with the sensitivity, in order to keep the variable substantially constant (neglecting the offset). In the invention the pressure in the integral chamber acts on a diaphragm 15, providing the bell-crank pivot, to displace it against a leaf spring 20 whose spring rate is such that the end 2B is displaced by the amount of offset of the end 2A. Thus the lever 1 moves parallel to itself and the link 5 may be moved to any position without affecting the offset.

Abstract: 1279194 Block copolymers SUMITOMO CHEMICAL CO Ltd 23 Feb 1970 [27 Feb 1969 26 May 1969] 8622/70 Heading C3P Block copolymers are prepared by polymerizing a free radical polymerizable monomer using as initiator a polymer prepared by polymerizing at least one conjugated vinyl or vinylidene compound giving a stable carbanion in solution using an alkali metal, organolithium compound or aromatic hydrocarbon-alkali metal complex as catalyst, and reacting the alkali metalterminated living polymer obtained with an azonitrile or oxygen, containing an azo group in the polymer chain or having a terminal hydroperoxy group. Free radical initiation may be effected by thermal decomposition of the initiator, or in the case of hydroperoxy terminated polymers by redox decomposition in the presence of a reducing agent, e.g. salts of metals in lower valence states, sulphites, acid sulphites, thiosulphates, mercaptans, sulphinic acids, amines and saccharides; in the presence of an inert hydrocarbon or halogenated hydrocarbon liquid, or an aqueous medium containing conventional emulsifiers and buffers. Specified conjugated monomers are vinyl aromatic hydrocarbons, vinyl pyridines, acrylic and methacrylic esters, vinyl ketones and conjugated dienes; and specified free radical polymerizable monomers are alkenyl halides, allyl compounds, acrylic acids, amides, esters and nitriles, methyl vinyl ketone, styrene, ethylene, dienes, maleic anhydride and diethyl maleate. The products may be blended with compatible polymers, e.g. polystyrene and polymethyl methacrylate, and moulded into shaped articles. In examples sodium terminated polystyrene reacted with azobisisobutyronitrile is used to initiate block copolymerization of (1) methyl acrylate, (2) methyl methacrylate and (3) vinyl acetate; sodium terminated poly- α,#-dimethylstyrene reacted with azobisisobutyronitrile is used to initiate block copolymerization of n-butyl acrylate; and sodium terminated polystyrene reacted with oxygen is used to initiate the block copolymerization of (5-7) methyl acrylate.

A voltage regulator system designed to operate reliably even in the presence of multiple failures of parts within the system is provided with a number of redundant sub-circuits so combined as to achieve this object. As shown, the voltage on a line 23 is derived from a source 24, 25 and is maintained constant by an arrangement comprising three reference voltage sources 13, 14, 15; three error amplifiers 10, 11, 12 each receiving one input from an associated reference source and another input from the line 23 for generating three error signals; and three pairs of input and output amplifiers, i.e. 16 and 17, 18 and 19, 20 and 21, which are connected in series across a supply voltage source, e.g. the regulated output voltage shown, each of the error signals being connected to an input and an output amplifier not connected in series, i. e. the error signal from amplifier 10 is connected to input amplifier 16 and output amplifier 19, the signal from 11 is connected to amplifiers 18 and 21, and the signal from 12 is connected to amplifiers 20 and 17. The output from each output amplifier 17, 19, 21 is applied over a current amplifier 22 to effect the desired control, which may be by way of shunt regulation as shown, or series regulation. The reference voltage sources may include Zener diodes, the error amplifiers 10, 11, 12 may comprise transistors connected as differential amplifiers, and the amplifiers such as 16, 17 may comprise series connected transistors Figs. 2 and 3 (not shown). The arrangement is such that if, for example, amplifier 10 should fail in operation so as to effectively short-circuit amplifiers 16 and 19, then the regulation continues by the action of error amplifiers 11, 12 on the amplifiers 18, 19, 20 and 21. Many other failures are also permissible, thus ensuring that the system will operate with the required high degree of reliability.
