Title: Improvements in the manufacture of reinforced plastic tubes
Filed: 1962-04-26
Abstract: 934,393. Moulding reinforced plastic tubes. S. PAVICEVIC. April 26, 1962 [April 28, 1961], No. 15910/62. Class 87(2). A mould, for producing reinforced plastic tubes, comprises a rigid tubular shell 1, end plates 10, 11, and an expansible core, Fig. 3, comprising two longitudinally split resilient tubes 2, 3 fitted one inside the other, the two splits being angularly dislpaced from each other. The outer split tube 3 is chamfered, adjacent to the split, so as to merge smoothly into the contour of the inner tube 2. The angular separation of the splits is maintained by pegs 2a. When the mould is assembled the volume enclosed by the core and end plates is rendered vacuum tight by resilient end seals 15 and by seals 8, 9 between the two split tubes. The shell and end plates are similarly sealed by end seals 16. One embodiment, Fig. 5 (not shown), comprises a divided shell with chambers 17, 18 for the passage of steam or coolant. The shell and core may be shaped as in Figs. 6, 7 (not shown), if tubes having wide or narrow end sections are required. In operation, glass fibre impregnated with liquid plastic is wound on to the core. The mould is assembled, and by means of ports 13, 14, the space between the core and shell, containing the plastic, is evacuated, while pressure is applied inside the core.

Abstract: 601,066. Filters. AIR MAZE (GREAT BRITAIN), Ltd. June 23, 1945, No. 16083. Convention date, Feb. 7. [Class 46] A filter for liquids of the type comprising a casing containing an apertured central tube surrounded by filter elements and carrying at one end a closure cap for the casing and at the other end a guide member fitting in part of the casing, is characterised in that the guide member has located therein a relief valve e which allows liquid to bypass the filter when the latter is choked. As shown, a housing 10 contains a slotted tube 14 around which are mounted filter packs 13 each having upper and lower surfaces and communicating with the slots 14a in the tube 14. The bottom of the tube is screwed to a member 15 which fits in an opening 10c and is provided with a spring- pressed valve 17a. The valve normally closes openings 18 in the member 15 but when the oil pressure in the housing is excessive the valve opens to allow unfiltered oil to pass to outlet B. The spring 19 is pressed by a nut 20 threaded on the tube 14 the nut being wired to the member 15 to prevent slackening. The upper end of the tube 14 is closed by means which includes hand-wheel 22 passing through an aperture in a cap 21 screwed to the housing.

In this last named circuit the value of the counter output is compared in an adder 48 with what is called a "filtered" value and includes a counter function obtained at the time of the preceding measurement. A mathematical analysis is included and a number of functions of the counter output are stored in a register 52 for feedback for subsequent calculation and for operation of a further overshoot alarm 74 through stores 72. The overshoot in this respect is reocrded at 76 and the threshold value, derived from 70, for determining overshoot is again different and selected for each channel.

In a bearing assembly a shaft is journalled in a bearing C housed in a resilient annular ring D itself supported in an annular retaining ring 25 in a fixed bracket A. In Fig. 1 rubber ring D comprises an annular body 40, projecting portions 46 having converging surfaces 44, 45 and ears 48, 49 joining the surfaces by neck portions. Grooves 27, 28 in retainer 25 accommodate portions of the ears. Axial displacement of the shaft causes the ears to rock in the grooves and to bend at the neck portion, greater radial load being taken by the folded ear than by the unfolded ear. Axial displacement is limited by co-operation of a surface (28b, Fig. 6, not shown) on the groove with a surface (54) on an ear. Angular displacement of the shaft axis causes rocking of those ears which are in the plane of the displacement, and twisting of the other ears.

Filed: 1957-05-24
Abstract: Ethylene oxide polymers having a reduced viscosity of at least 1,0 (measured at 0,2% concentration in acetonitrile at 30 DEG C.) are stabilized by addition of a compound with the formula: <FORM:0869111/IV (a)/1> wherein R1, R2, R3 and R4 represent H or methyl.  Preferably 2%-5% of stabilizer is employed, either being added to a suspension of the polymer in a diluent which is then evaporated, or being dissolved in a solution of the polymer, e.g. in methanol, acetic acid, acetonitrile, benzene or water. Alternatively the stabilizers may be mixed with the solid or molten polymers. Stabilizers specifically mentioned are N, N, N1, N1-tetrakis-(2-hydroxy-ethyl or -propyl) ethylene diamine; N, N-di-(2 hydroxypropyl)-N, N1-di(2-hydroxy-ethyl)-ethylene diamine; N, N, N1-tri-(2-hydroxypropyl)-N1-(2 hydroxyethyl) ethylene diamine; N-(2-hydroxypropyl)-N, N1, N1-tri(2-hydroxy-ethyl) ethylene diamine.

Title: Method and apparatus for spray drying flowable liquid-containing materials

Filed: 1960-05-10
Abstract: 948,072. Spray-drying. B. E. BUDAHN. May 10, 1960, No. 16544/60. Heading B1B. Flowable liquid-containing materials, such as whey, are dried by spraying them into a drying chamber at the centre of an incoming flow of hot turbulent dry air having a high degree of vorticity, the dried particles being deposited on the floor of the chamber from which they are removed at predetermined intervals depending on the time taken for the quiescent particles to stabilize into a non-hygroscopic condition. As shown, hot, dry air enters the drying chamber from a duct 17 in the form of a turbulent vortex which is induced by a fixed turbinating device 18. The material to be dried is sprayed into the chamber through a nozzle 21 positioned at the centre of the incoming air stream. The dried particles settle on the floor 12 whilst the air stream, after being directed downwardly by an adjustable curtain 34, is discharged at 16. The dried material is removed at regular and relatively short intervals, e.g. of five minutes, or less, by propelling the rockable scrapers 22 along the chamber floor from the end wall 11 to the trough 31. The material is then discharged laterally from trough 31 by an auger type conveyer 32 into an elevator (not shown). The scrapers are then returned to their original position adjacent end wall 11.

Title: Improvements in disc brakes for vehicles
Inventor: REDMAYNE LEONARD
IPC: F16D65/54
Filed: 1954-06-04
Abstract: 761,479. Disc brakes. GIRLING, Ltd. June 3, 1955 [June 4, 1954], No. 16561/54. Class 103 (1). In an hydraulically operated " spot-type " disc brake, members associated with the opposed friction pads are positively coupled together by a coupling member which prevents appreciable movement of either pad away from the brake disc through the engagement of the other pad with the opposite face of the disc, the coupling member incorporating sliding ratchet whereby its effective length is automatically and progressively reduced as the friction pads wear. In a disc brake in which non-rotatable hydraulically operated piston and cylinder mechanisms 21 are situated on either side of a rotatable brake disc 10, covering a small portion only of the periphery on the brake disc 10 ; the latter being secured to the vehicle wheel 16, and pads of friction material 25 are adapted to engage the radially extending sides of the brake disc (Fig. 2 showing the right-hand pad in the unworn state and the left-hand pad in the worn state). Each pad of friction material is provided with a rigid backing plate 24 which is backed by a thrust member 23 secured to a piston 22. Each backing plate 24 is prevented from relative angular movement by a peg 27. Secured to each backing plate 24 is a lug 29 ; one lug carrying a screw-threaded rod 30 which passes freely through a hole in the other lug. A sheet metal collet member 33 is mounted on the latter lug and provided with spring fingers 34 -engaging the screw thread on the rod to prevent any appreciable movement of the friction pads away from each other when they are frictionally applied; as for instance when the vehicle is travelling round a corner and the lateral movement of the brake discs tends to push one of the friction pads away from the disc. As the friction pads wear, the backing plate 24 moves towards each other and the spring fingers automatically engage the next thread to shorten the effective length of the rod and so maintain the correct relative spacing between the operative surfaces of the friction pads. Axial expansion of the disc when heated is allowed for by elongating the hole in the rod 30 for the pin 31 in the first lug 24. Specification 688,382 is referred to.
