IPC: A46D3/06
Filed: 1948-07-13
Abstract: 644,847. Making brushes. DEHN, S. G. (Northam Warren Corporation). July 13, 1948, No. 18823. [Classes 83 (ii) and 83 (iv)] Angular bending ; shearing.-A subpress mechanism for forming tapered tubular brush-stems in a single cycle of operations cuts a tapered blank from a strip, bends the blank to V-shape about a preforming anvil and then completes the bending between two opposed tube-forming dies. A base 22 supports a plate 20 carrying stationary dies 5, 6 which co-operate with spaced cutting-dies 7, 8 reciprocated from the press head to shear a tapered blank from a strip A. The dies 7, 8 are mounted on a member 25 on a head 26 guided by columns 27 on the base. A preforming anvil 9 is supported by the base. Within the dies 7, 8 is positioned a bending-die 16 retracted by springs 34 against adjustable abutments 23 on the member 25. A bending-die 12 supported on guide rods 42 on the head 26 is laterally moved by rolls on the die carriage engaging fixed cams on the base 22. On descent of the dies 7, 8 the blank is sheared and pushed on to the preforming anvil 9 converted to V-shape and housed on the space between the dies 7, 8. On the upstroke of the dies 7, 8 the blank is moved upwards and the cams move the bending-die 12 horizontally in alignment with the blank. The bending-die 16 is then arrested by adjustable stops, not shown, and the dies 7, 8 with the blank and the die 12 continue the upward movement until the blank is engaged by the die 16 and a recess 13 on the die 12 and bent to tapering tubular form. The die 16 and the recess 13 may be shaped to produce a stain with a tapered part lap jointed and a cylindrical part butt jointed. When the cutters 7, 8, member 25 and head 26 start the downward movement the die 16 remains stationary until the abutment 32 engages the back of the die 16. The die 12 with the completed brush-stem is moved horizontally and on the next reverse movement is ejected from the die by a vertically movable ejector bar projected into the die cavity.

Title: A motor vehicle suspension system
IPC: B60G21/06
Filed: 1949-07-22
Abstract: 670,361. Vehicle suspensions. CALLEBAUT, J. E. G. P. July 22, 1949 [July 24, 1948], No. 19332/49. Class 108(ii) In a motor vehicle having air chambers located between the axle ends and the frame, the chambers are so interconnected with one another and with the induction manifold that the height of the frame above the axle ends on one side of the vehicle can be adjusted so as to maintain the body on an even keel. whether proceeding straight or on a curve. The valve controlling the interconnections may be operated manually, by a pendulum device or electrically, and the operation of the valve may depend automatically upon deflection of the steering wheel or the direction indicators. Each air chamber may be divided by a partition into two compartments, one of which may be subjected to manifold depression and the other to air pressure. As shown in Fig. 1, a flexible air chamber 3 is disposed between the frame 2 and the axle 1. The normal position of the axle is determined by the usual spring 6, but its distance from the frame may be adjusted by connecting the inlet 5 to a source of air pressure on to the induction manifold. In the arrangement represented by Fig. 2, each axle end is connected to the centre portion 22 of a two compartment flexible air chamber whose end walls are rigidly connected by rod 25. The eight compartments are interconnected and connected to the rotary valve 15 as shown so that movement of the valve in one direction or the other tends to cause the vehicle frame and body to lift on one side and drop on the other. Relative movement of the partition and the end walls of the air chamber may be obtained by introducing pressure or partial vacuum to one compartment whilst the other is open to atmosphere, or by introducing pressure to one compartment and partial vacuum to the other. according to whether the two connections shown on the left and right of the valve 15 are connected to a source of air pressure and/or manifold depression respectively, or whether one connection is left open to atmosphere.

Title: Improvements in and relating to the electric indication of fairways of great lengths
IPC: G01S1/02
Filed: 1920-07-08
Abstract: 147,563. Siemens & Halske Akt.-Ges. Dec. 19, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Inductive signalling.-In systems for indicating fairways by the inductive action of alternating current in a submarine cable, the E.M.F. induced in a ship's receiving-apparatus is proportional. to the frequency of the cable current, but, on the other hand, currents of high frequency are more rapidly attenuated in the cable and their inductive effects at the surface are more greatly reduced by the intervening sea-water. High frequencies are therefore more suitable for short cables and low frequencies for long cables stretching into deep water. For a given cable laid at known depths the E.M.F. induced at the surface at different points along the length of the cable can be computed for different frequencies. In general this effect decreases continuously along the cable, but the minimum may also occur at an intermediate point where the cable passes a region of deeper water. The invention consists in choosing the frequency of the current so that the minimum induced E.M.F., whether this is found at the end of the cable or at an intermediate point, will be the highest possible for a given strength of current at the shore end.

Title: Improvements in and relating to the extrusion of film
Inventor: HUDSON RONALD AUGUSTUS
IPC: B29C48/08
Filed: 1955-07-06
Abstract: <PICT:0786449/IV (a)/1> <PICT:0786449/IV (a)/2> A die for the extrusion of molten organic thermoplastic material in the form of flat film having beaded edges has a slot orifice and a centre portion in which the internal surfaces of the opposed lips are parallel to each other over a certain length measured in a direction at right angles to the extrusion orifice and terminating at the extrusion orifice, and an end portion at each side of the centre portion in which the internal surfaces of the opposed lips are parallel to each other over a similarly measured length, terminating at the extrusion orifice, that is less than the corresponding length in the centre portion of the die, the parallel-walled extrusion channel formed between the lip surfaces being preceded in the centre and end portions by a channel of greater width through which the molten material may be supplied. As shown in Fig. 1, which is a perspective view of the end portion of a die, with end plate removed, and in Fig. 2, which is the same view with one lip removed from the die, 1 represents the body portion of the die to which are bolted the lips 2 and 3.  The lip 3 is substantially U-shaped in section, the upper limb being bolted immovably to the body portion of the die, and the lower limb being slightly flexible and capable of being moved towards or away from the upper limb by means of a series of bushes 6, spaced across the whole width of the die; in this way the width of the slot orifice may be adjusted to give a film of uniform thickness across the whole central region.  The body portion of the die forms with the lips a passageway 7 for the molten material, and the lips form a parallel-walled extrusion channel terminating at the slot orifice 9. The length of the parallel portion of the lip surfaces is decreased at each end of the die by grinding one or both of the lip surfaces in the manner shown at 10.  The two ends of the die are closed by end plates (not shown), one of which is provided with an inlet for supplying the molten material to the passageway 7.  Since the volumetric rate of extrusion of the melt is proportional to the length of the parallel section of the die lips in the direction of extrusion, the volumetric rate of extrusion is greater through the end portions of the die slot than through the remainder of the slot, so that the extruded film is formed with a bead along each edge.  The thermosplastic material extruded may be polythene, a polyamide, polyvinylidene chloride, rubber hydrochloride, polystyrene or, particularly, polyethylene terephthalate.  The beaded edges render it possible to increase the uniformity of width reduction when the film is stretched longitudinally after cooling.
