Abstract: 1,127,391. Baling presses. AL-JON Inc. 22 March, 1966 [22 March, 1965], No. 12662/66. Heading B3H. Apparatus for crushing a car body 20, Fig. 5, comprises an hydraulically - operated arm 58 for crushing the car body on a platform 38 over which it is moved by a predetermined amount between crushing stages until it passes through the apparatus. The body is also crushed against a side wall 74 by a ram 60, and the apparatus is transportable having a hook attachment 48 at one end and a roller (52), Fig. 3 (not shown), and steady (54) at the other to facilitate loading on to a truck. In one example the body is drawn through the apparatus by a winch 62 operated hydraulically by a motor 104, the winch-cable 110 passing round a pulley (112, Fig. 3) at the back of the apparatus and through the gap between the pivoted, lower end of the stepped arm 58 and the platform 38. Hydraulic jacks 76 are connected to each side of the arm 58, and a further jack 80 operates the ram 60, the rams being connected to an hydraulic circuit, Fig. 12 (not shown), pressurized by an I.C. engine 36 or an electromotor. Two mechanically-linked sets of controls may be provided for the rams 76 which also control the winch, unless the winch-valve is in a neutral setting, and the jack 80 if its valve is not in the "off" position. When the car is winched on to the platform 38 one of the controls is operated to start downward movement of the arm and movement of the ram and stop automatically the winch. As the arm 58 is raised and then ram 60 withdrawn, the winch operates to advance the car by approximately one step of the arm. The crushing operations are repeated until the whole of the body can pass under the arm, Fig. 7 (not shown). In order that sufficient hydraulic flow may be available for fast operation and enough pressure for the final stages of crushing, a doublepump unit is used. A hinged ramp 92, retractable by a winch 96 and having an extension 94, is provided at the entry end of the apparatus. A hinged deflector 98 is also provided. A chain conveyer 64, Figs. 8a, 8b, may replace the winch, the chain drawing the crushed body on to a rigid frame 124 having a recess 130 to receive lifting forks. A drive for the chain 132 is disposed beneath the platform 38.

Title: Improvements relating to rolling mills for rolling hollow bodies such as tubes
IPC: B21B19/14
Filed: 1937-05-06
Abstract: 495,079. Rolling tubes. DEUTSCHE ROHRENWERKE AKT.-GES. May 6, 1937, No. 12903. Convention date, July 25, 1936. [Class 83 (iv)] Skew-rolling.-The internal diameter of tubes &c. are increased by external rolls arranged in sets which rolls alternately engage the tube, &c. which contains a conical mandrel or internal rolls. The axis of the rolls are inclined to the axis of the tube &c., and the rolls are arranged so that the greatest diameter of one set of the outer rolls is adjacent or opposite the smallest diameter of the rolls of the other set. One set of the outer rolls may consist of cylindrical short rolls. In the arrangement shown in Fig. 1, the rolls 1 3 grip the tube 7 at the part to be increased in internal diameter, and force it over the mandrel 5. During this time the other set of rolls 2, 4, Fig. 2, are out of engagement. The rolls 1, 3 have their largest diameter at the entrance end of the tube. The rolls 2, 4 have their largest diameter towards the discharge end of the tube. After the front end of the tube has been rolled over the mandrel, the rolls 2, 4 engage the enlarged parts of the tube, and the rolls 1, 3 are moved away. In a modification, internal rolls replace the mandrel. The outer rolls of the first and second halves of the sets of rolls need not have the same dimensions. The second half may have short cylindrical rolls or have a larger diameter than the first half. In the latter case the first half need not be moved away from the tube.

Filed: 1939-04-29
Abstract: 528,210. Ironing presses; calendering machines. CLEGHORN, W. G. April 29, 1939, No. 12914. [Classes 42 (i) and 138 (ii)] A calender or like machine of the roller and concave bed type has the bed constituted by a plurality of sections extending the length of the roller and each movable substantially radially under the action of tension springs, fluid pressure &c. so that the pressure is substantially uniform over the bed. Each bed section 23 is provided at each end with guide pins 24, 25 movable in slotted guides 26 arranged substantially radially of the cylinder 28 and as shown is drawn inwardly by a spring 29 anchored to a nut 31 connected to the outer guide pin and to a nut 32 on a screw 34 mounted in a bracket 30 on the frame and carrying a bevel pinion 37 engaging a wheel 38 whereby the tension of the springs of all the beds can be adjusted simultaneously, the screws 34 permitting individual adjustment whereby the effective weight of each bed section due to its position around the rollers can be individually compensated. The bottom sections and the upper sections at each side are guided by two slot guides so as to have a combined lateral and radial movement necessitating universal connections 52 in the screw spindles. The nut 31 and consequently the spring 29 is held against rotation by a lock nut 39, and the connection to the guide pin 25 includes a pivoted pawl plate 60 which in the event of failure of the spring 29 is tilted by a spring 61 so that it engages an abutment 62 on the slotted guide. In a modification each spring 29 is replaced by a cylinder and plunger subjected to a common fluid pressure to press the bed sections inwardly, compensation for the effective weights of the bed sections being effected by suitable dimensions of the various cylinders, and by applying the final pressure through a diaphragm provided in each cylinder equal and uniform pressure is applied to each bed section. The adjacent edges of the bed sections may be inclined or curved or serrated to prevent the work from being drawn between them. The outer surface of each section may be provided with a plate overhanging the space between sections to form chamber connected with a suction channel leading to a channel in the machine frame.

Title: Improvements in or relating to thermionic valve amplifiers with negative feedback
IPC: H04B3/08
Filed: 1946-04-30
Abstract: 611,390. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and ROCHE, A. H. April 30, 1946, No. 13043. [Class 40 (vi)] In a wide-band amplifier having a negative feed-back path, the gain of the amplifier at certain frequencies is adjustable by an amount depending on the magnitude of the cathode current of one or more of the valves in the forward amplifying path, thus compensating for changes in the gain/frequency characteristics of the amplifier due to ageing of the valves. The original gain/frequency characteristic of a negative feed-back amplifier on ageing of the valves remains substantially unaltered at the extremities of the frequency band where the phase-shift round the feed-back loop is 90 or 270 degrees, but falls at the mid-frequencies of the band where the feed-back loop phase-shift is approximately 180 degrees, Fig. 1 (not shown). Fig. 2 shows a negative feed-back repeater, the drop in gain near the mid-band frequencies of the amplifier due to valve ageing being corrected by including in the negative feed-back path a thermistor 23 of the type described in Specifications 541,922, 555,563 or 557,559, [all in Group XXXVI]. The networks 14, 15 may be of the type described in Specifications 499,315 and 514,567, Figs. 3 and 4 (not shown). The thermistor 23 has its cathode heated by the D.C. cathode current from one or more of the valves in the forward amplifying section 3 of the amplifier and has a characteristic such that the resistance exhibited by the element 22 is reduced with increase in the temperature of cathode 24. Thus, the networks 14, 15 in conjunction with thermistor 23 may be designed to exhibit a feed-back characteristic dependent on the cathode current of the valves in section 3 of the amplifier. The networks 14, 15 may be designed to produce any given frequency or phase characteristic and the thermistor could be included for example in the coupling network between stages. The embodiment of the invention in a repeater of the type suitable for use in unattended repeater stations or in a submarine cable circuit is described with reference to Fig. 5 (not shown), the H.T. supply for the repeater being fed over the cable circuit and filtered from the signal currents by low-pass filters.

[Classes 39 (i) and 40 (iii).] A television apparatus comprises a transmitting plate B negatively charged from a source of potential D and a receiving plate E electrically connected to the plate B of the same geometrical shape, together with means for changing into light effects the differences of potential that exist between the different points of the plate E. An image of the object to be transmitted is projected on to the plate A, which by the photoelectric effect becomes charged at different points to different potentials. It is stated that by electrically connecting the two plates, e.g. by Hertzian waves or by wire C, the distribution of potential on plate E becomes identical with that on plate B. The plate B is kept in a container A filled with hydrogen or a rare gas at low pressure. The plate E is kept in a container F filled at low pressure with nitrogen, neon, carbon dioxide, argon, mercury, or with any suitable gas or mixture of gases according to the shade or shades of colour to be obtained. Current from a small induction coil is fed to electrodes G and it is stated that the electric discharge renders the gases in the container F luminescent and reproduces the illumination falling on the plate B. If a high voltage is employed the shadow effects will penetrate a certain distance into the gaseous medium and give relief effect to the images. It is stated that by maintaining a magnetic field across the plate E the luminous effects can be accentuated. The plate B may be coated with an amalgam of potassium, sodium, rubidium, caesium, or of their alloys.

Abstract: Graft copolymers are prepared by first copolymerizing a polyvinyl monomer with a homopolymerizable C3-C6 mono-olefin in the presence of a Friedel-Crafts catalyst to produce an oil soluble backbone polymer having pendant vinyl groups, and then reacting the resultant copolymer in the presence of a free-radical polymerization catalyst with a homopolymerizable ethylenically unsaturated monomer having an active substituent capable of improving the properties of lubricating oil, e.g. dimethylaminoethyl methacrylate, diethylaminoethyl acrylate, diethylaminoethyl vinyl ether, 4-vinyl pyridine, 2-vinyl-5-ethyl pyridine, N-vinyl pyrrolidone, N-methylol acrylamide, acrylic, methacrylic and crotonic acids, methyl methacrylate, allylamine, bis(betachloroethyl vinyl) phosphonate, diallyl phosphite and 2-(vinylthio) benzothiazole.  Polyvinyl monomers specified are divinyl benzenes, toluenes, xylenes and naphthalenes, and trivinyl benzene. Isobutylene is the preferred mono-olefin for copolymerization with the polyvinyl monomer, but the use of amylene-1 also is described. Free-radical catalyst specified are organic peroxides and hydroperoxides, ozone, ozonides, sodium and barium peroxides and azobisisobutyronitrile. In the examples graft copolymerization is carried out by dissolving the backbone polymer in n-heptane, polymerizing the monomer in the polymer solution, and recovering the graft copolymer by precipitation.  The Specification describes also the copolymerization of amylene-1 with 0.2 mole per cent. of divinyl benzene, using aluminium trichloride as a catalyst.ALSO:As additives to lubricating oils there are used graft copolymers obtained by copolymerizing an ethylenic monomer having an active substituent capable of improving the properties of lubricating oil with a copolymer of a C3-C6 mono-olefin and a polyvinyl monomer, e.g. a copolymer of isobutylene or amylene-1 with divinyl benzene. Active monomers specified are diethylaminoethyl acrylate, dimethylaminoethyl methacrylate, methyl methacrylate, diethylaminoethyl vinyl ether, 4-vinyl pyridine, 2-vinyl-5-ethyl pyridine, N-vinyl pyrrolidone, N-methylol acrylamide, acrylic, methacrylic and crotonic acids, allylamine, diallyl phosphite, bis - (beta - chloroethylvinyl) phosphonate and 2-(vinylthio) benzothiazole.  The lubricating oil to which the graft copolymers are added may be of the mineral type or may be of the type obtained by the polymerization of olefines. The additives function to improve the viscosity index and other properties of the oil.
