Title: Binders in powder form crosslinking spontaneously under the influence of heat
Inventor: APPEL HANS GUNTER
IPC: C08F8/00
Filed: 1970-01-02
Abstract: 1286061 Coating FARBENFABRIKEN BAYER AG 2 Jan 1970 [3 Jan 1969] 219/70 Heading B2E [Also in Division C3] Coatings are produced on substrates by applying thereto solid particles of a fusible binder, which crosslinks spontaneously on heating and has a softening point in the range 50-150‹C, and hardening the coating by heating above 130‹C. The binder used is the product obtained by reacting (a) a homopolymer or copolymer of an ethylenically unsaturated monomer containing a hydroxyl group with (b) an alkoxymethyl isocyanate having 1 to 18 carbon atoms in the alkoxy group or allyloxymethyl isocyanate. Suitable hydroxy monomers include mono- or bis-hydroxymethyl norbornene, phenylallyl alcohol, hydroxyalkyl esters of acrylic, methacrylic, fumaric or maleic acid, trimethylolpropane monoallyl ether and glycol monovinyl ether. The hydroxy monomers can be copolymerised with monomers which do not react with isocyanates, e.g. (meth) acrylate esters, styrene, alkylstyrenes, (meth) acrylonitrile, α-chloroacrylonitrile, vinyl acetate, vinylidene chloride, (meth) acrylamide and N-alkyl derivatives thereof, N-vinylacetamide, diacetone acrylamide and (meth) acrylic acid. Before being hardened the binder coating may be fused by heating at 50-150‹C. The binders may be admixed with pigments (e.g. titanium dioxide), extenders, fillers and plasticisers (e.g. dicyclohexyl phthalate). The binder can be applied with a spray gun (operated with compressed air) or it can be electrostatically sprayed; alternatively the article to be coated can be dipped in a fluidised bed of the binder. In Examples coatings are applied to steel panels.

Title: Indirect heat exchanger
IPC: F28G9/00
Filed: 1958-01-03
Abstract: 826,888. Heat exchangers. ROSENBLADS PATENTER A. B. Jan. 3, 1958 [Jan. 7, 1957], No. 276/58. Class 64(3) [Also in Groups H and XXVIII] A heat exchanger in which two fluids exchange heat in flowing through passages separated by a heat-conducting wall is so arranged that it may be turned on an axis and the pipe connections leading the respective fluids to and from the heat exchanger interchanged, the arrangement being such that at least one of the fluids may thereby have its flow direction through the heat exchanger reversed or it may be caused to flow through the fluid passages in the heat exchanger previously traversed by the other fluid. The invention is described particularly in its application to plate and tubular heat exchangers in which one of the fluids deposits sediment or sludge in the fluid passages through which it flows. By a reversal of flow or interchange of fluid in these passages the sediment or sludge may be flushed to waste. Fig. 11 shows a typical form in which when the heat exchanger 1 is turned on the pivot 8, the connections such as 2a, 2b for one fluid normally coupled for example to respective connections 12a, 12b, may then (as shown) be coupled to connections 12b, 12a respectively to give a reversal of fluid in the passages served by connections 2a, 2b or coupled to connections 13a, 13b to change the fluid flow direction in these passages.

Title: Pipe-driving apparatus
IPC: E21D9/06
Filed: 1976-01-06
Abstract: 1537371 Pipe-driving apparatus GEWERKSCHAFT EISENHUTTE WESTFALIA 6 Jan 1976 [9 Jan 1975] 00342/76 Heading E1F Pipe-driving appratus (shown in plan in Fig. 2) includes force-applying means such as a ring 15 engageable with a pipe to drive it into the ground, the ring being mounted for axial and rotary movement, and means being provided to adjust the position of the ring about its rotational axis to control the torsional force imparted to the pipe during driving. As shown, the apparatus comprises a main frame composed of floor beams 11, rear upstanding beams 12, and cross-pieces 14, 27. Double-acting rams 13 are connected to the rear beams 12 and ring 15 through ball and socket joints (16, 17). The ring 15 is guided for axial movement by guide shoes 18 which slidably engage the floor beams 11 but prmit at least partial rotation of the ring 15 about its axis. The rotational position of the ring 15 is adjusted by means of a guide rail 19 which is pivoted to the cross-piece 14 at 20 so as to be swingable in directions S. The ring 15 has a pair of lugs supporting guide elements 22 engageable on opposite sides of the rail 19 and located in selfadjusting curvilinear bearings 23. The position of the rail 19 is adjusted by set screws 25 located in bores in brackets 26 supported on the cross-piece 27 and contacting the opposite sides of the rail 19. Thus when the rail 19 is adjusted to move the ring 15 from its central position, actuation of the rams 13 produces a torque which is transferred to the driven pipe, ideally to counteract a known tendency of driven pipes to rotate as they are advanced.

Title: Distribution of television signals or other carrier waves by wire line
IPC: H04H20/78
Filed: 1950-01-09
Abstract: 678,391. Preventing inductive disturbance; distributing music &c. COMMUNICATIONS PATENTS, Ltd., and KINROSS, R. I. March 20, 1951 [Jan. 9, 1950], No. 542/50. Class 40 (iv). Interference caused by the induction of longitudinal (push-push) currents in a two-wire line 11, 12 is reduced by the provision of series-connected inductors 15, 16 presenting high impedance to push-push current and low impedance to push-pull current and a shuntconnected centre-tapped inductor 21 presenting low impedance to earth to push-push current and high impedance to earth to push-pull current. The inductors 15, 16 are wound on a common core, are closely coupled, and are so connected that the magnetic flux resulting from a push-push current in the line is additive whereas that resulting from a push-pull current is subtractive. The inductor 21 has its two halves wound on a common core, closely coupled and so connected that the flux caused by a flow of push-push current to earth is subtractive whereas that caused by a push-pull current is additive. Additional inductors of either type may be employed if required. The invention is particularly applicable to distribution systems for television. Thus, television signals modulated on a 30 Mc/s. carrier are sent into the line by transmitter 13 and the inductors are connected between the line and the primary winding 17 of a balanced-tounbalanced transformer the secondary 18 of which feeds a co-axial cable 19 leading to a subscriber's receiver 14. The sheath of the cable and a screen 20 between the windings of the transformer are earthed.

Filed: 1949-01-08
Abstract: 661,396. Valve gear for pneumatic tools. MERCER, A. C. Feb. 17, 1949. [Jan. 8, 19491 No. 580/49. Class 122(ii). In a pneumatically operated tool, driven by a piston 4 reciprocating in a cylinder 1 having compressed air admitted alternately to each of its ends through ports controlled by a slide valve 9 operated by compressed air from the cylinder 1 being supplied alternately to each of its ends through ports in the cylinder wall controlled by the piston, the slide valve is housed in a slide way 22 in the tool body at the rear end of the cylinder and transverse thereto and has either end connected to atmosphere through ports in the cylinder wall and a passage through the piston and piston rod at the same time as the piston connects pressure air to the other end of the valve. When operating from rest the valve is in the position shown due to a light spring 26 provided at one end of the valve and air supply through passage 8 is directed through port 27, passage 28 and pcrt 29 in the cylinder wall to the forward end of the cylinder and drives the hollow piston 4 inwards and at the same time air from the rear end of the cylinder is exhausted through ports 30 and 31 to atmosphere. The piston moves inwards until it uncovers a port 32 in the cylinder wall thereby supplying air through a passage 33 to the underside of the valve 9 which is thus moved to its other operating position; air from the top of the valve is exhausted to atmosphere through a passage 34, a port 35 in the cylinder wall, an annular groove 36 in the piston, which groove registers with the port 35 at the same time as the piston uncovers the port 32, radial holes 37 in the piston and a passage 38 in the piston rod. Air is now supplied to the rear end of the cylinder through port 30 and exhausted to atmosphere from the forward end through port 29, passage 28 and ports 27 and 39 and the piston moves outwardly until annular groove 36 registers with port 32 and the piston simultaneously uncovers port 35 thereby supplying pressure air to the top of the valve and connecting its underside to atmosphere, the valve returns to its original position and the cycle recommences. Lubricating oil is supplied in an atomized form to the working parts from a wick immersed in an oil chamber in the tool handle 2 and having one of its ends protruding into the air supply passage.

Title: Improved method and means for charging tubular containers with mouldable materials
IPC: B65B3/14
Filed: 1949-01-11
Abstract: 662,334. Fitting-machines; filling containers. WEBSTER, Ltd., E., and WEBSTER, E. Jan. 9, 1950 [Jan. 11, 1949], No. 713/49. Classes 94(i) and 125(ii) A method of filling containers with liquid, plastic or powdered mouldable materials, e.g. salves, particularly containers of the type having an inner cup which carries the base of a stick of the salve or lipstick and which is movable in the container to project the end of the stick for use, comprises filling tubular moulds with the salve, moving the moulds into the containers, and subjecting the interiors of the moulds to air pressure to discharge the contents of the moulds into the containers. Cylindrical moulds 21 clamped by a plate 22 in the recessed openings 18 formed round a piston 14, are retracted through holes 17 formed in the cover plate 15 of a cylinder 10 when the piston 14 is moved downward. In the lowest position of the piston 14, which may be operated by a double acting air cylinder, the open top of each mould rests even with the upper face of the cover plate 15 which forms the bottom of a charging chamber 27, the sides of which are formed by a centre plate 29 and an outer ring plate 28 the latter being clamped by bolts 16 to the cylinder 10. In this position the moulds are filled with the salve which has been supplied to the chamber 27. On raising the piston 14 the moulds 21 project through the openings 17 to engage the inner cups 47 of containers 36 which are held coaxially above the openings 17 in recessed openings 34 in a plate 31. The latter is located above the plate 28 by dowels 33 and fixed by screws and distance blocks 32. Pipes 44 of approximately equal length are fixed by nuts 45 into holes 43 equally spaced round the cylinder 10 and feed compressed air at the same pressure to each of the inlets 25 formed at the base of each mould to force the contents from the moulds into corresponding cups 47. The piston is then lowered, the cylinder 10 being vented by means of a tap 46, or by the operation of a two-way valve in the compressed air supply system (not shown), and the moulds 21 are withdrawn from the containers 36. The containers are removed from the machine by unscrewing a nut 40 and removing a top plate 39. A stripping plate 48 may be included to facilitate the charging and the discharging of the machine. Various sized containers and correspondingly sized moulds, all having standard sized flanges, can be fitted to the machine.

Title: Improvements in Shock Absorbers.
Inventor: CARTER RUSSELL STEENBACK
IPC: F16F9/14
Filed: 1917-01-15
Abstract: 103,986. Carter, R. S. Feb. 4, 1916, [Convention date]. Dash-pots.-A shock-absorber for automobiles, particularly of the kind described in Specification 13608/14, has an elastic chamber wall of large area so as to absorb part of the shock resiliently and also control the passage of liquid around the piston. A sector-shaped chamber 3 is pressed from sheet metal in two parts, which are secured together by peripheral flanges. The walls are bossed outwardly at 7, 7<a>, Fig. 4, for the hub 8 of the spring piston 9, an indentation 10 being formed in the boss 7 to press the hub towards the opposite side. A resilient false wall 31 the full width of the casing is placed within the curved wall 4 of the casing, and its inward movement is limited by an adjustable screw 33. A hole 35 is made in the wall 31 to permit passage of fluid, the hole being preferably on the side towards which the piston 9 moves as the main spring recoils. On the up-stroke, shock is absorbed by the resilience of the spring piston 9, the flexible side walls of the casing, and the wall 31, as well as by fluid resistance, the deformation of the wall 31 diminishing towards the end of the stroke. On the return stroke, the pressure of the fluid forced through the hole 35 prevents displacement of the wall 31. The spring piston 9 is secured in the hub 8 with slight angular play. The lever 16, which is connected to the main spring or spring shackle, has one end turned over on a filling-piece 21 and is adapted to fit over a sleeve 17 surrounding the squared end of the hub 8. Serrations on the lever and sleeve permit of angular adjustment. Both the lever and sleeve are split and are clamped on the hub 8 by a bolt 24. The edges of the hole in the boss 7<a> are clamped between two washers 11, 13 engaging shoulders of different diameter on the hub 8, a spring washer 15 keeping the joint fluidtight. The spring washer may be compressed, before the bolt 24 is tightened, by means of a broad-headed screw inserted in a hole 29. The washer 15 is prevented from turning on the hub 8 and is provided with a pointer to indicate the position of the piston 9.
