Abstract: 838,369. Piston packings; joint-making packings; stuffing-box substitutes. MERKEL, E. Jan. 26, 1959 [Feb. 4, 1958], No. 2826/59. Classes 122 (1), 122 (3) and 122 (5). [Also in Group XXII] An endless sealing-ring comprises a sleeve 11, Fig. 3, which may or may not be provided with a core 3, and consists of a single piece of synthetic material spun into the desired crosssection. As shown in Fig. 1, the sealing-ring is produced from a ring 1 (of polytetrafluoroethylene or any other of the polymers of halogen-carbons) press-fitted on a rotating shaft 2, by advancing in the directions a, b two tools 4, 8 which are arranged so that their cutting-edges 6 machine off a thin strip 5 of the material and by virtue of grooves 7 in the tools roll or spin the strip around a core 3 surrounding the ring 1. The two edges of the sleeve so formed may be arranged to abut or overlap, the position of such joint being determined by the position of the core on the ring 1. The core ring 3 may be provided to act only as a mandrel during the spinning operation and then removed. Other sealing-rings of generally U or V cross-section are described wherein the tools 4 are shaped accordingly and the core ring is removed after manufacture.

Title: Throttle moderator
IPC: F02D11/08
Filed: 1975-04-22
Abstract: 1510961 Throttle controls PA MANAGEMENT OF CONSULTANTS Ltd 22 April 1975 [22 Jan 1974] 02849/74 Heading F1B The setting of the throttle valve of an I.C. engine is regulated by the inlet manifold pressure. The operator's accelerator control is connected to rod 12 which passes through one end-wall of cylinder 1 and carries a plunger 11, which forms an abutment for compression spring 5 which also abuts piston 4. Rod 8 is connected to the engine throttle valve and to piston 8 and compression sping 6 is positioned between piston 4 and the other end-wall of the cylinder. Atmospheric air vents 3 are formed in the one end-wall and a port 2 in the cylinder wall is connected to the inlet manifold, when inlet manifold pressure is low, e.g. when the engine is idling, the force of spring 6 is reduced by the vacuum acting on the piston, as the throttle opening increases, absolute pressure in the manifold rises and resistance to movement of rod 12 increases. In a modification, Fig. 2, the rod 12 passes freely through piston 4 and has a head 2 a. Spring 4 a is positioned between head 2 a and piston 4. Inlet manifold vacuum is communicated to the cylinder through port 2 and acts on piston 4. When the operators control is released a return spring on the control overcomes the effect of vacuum and spring 4 a.

Filed: 1970-01-22
Abstract: 1287366 Beta particle thickness measurement L STRENG 22 Jan 1970 3202/70 Headings G1A and G1U Apparatus for measuring the thickness of a layer 13 on a carrier 35 detects the backscattered # radiation 12 in a Geiger-Muller tube whose pulse output is passed through an AND gate and a binary frequency division device 17 to an integrator 22. The integrator output is proportional to the pulse rate which itself is a non- linear function of the thickness. This signal is backed off by the voltage produced by battery 27 to compensate for the scatter from the carrier and the resultant signal passes through network 28 to a linearizing amplifier 29 which derives a signal having an inverse relation to the thickness of the layer so that the output which feeds meter 31 is linearly related to the thickness of the layer. The sensitivity of meter 31 can be charged by switch 32. A measuring clock 18 is connected to both open and shut AND gate 19 at the required times and also to provide an interrogation pulse to integrator 22. In operation the backscatter from the bore carrier 35 is measured and the battery voltage 27 adjusted until meter 31 indicates zero. A standard having a layer of known thickness is measured and network 28 adjusted to give the correct indication on meter 31 with switch 32 in its right hand position. Switch 32 is changed over and resistor 33 adjusted until the meter indicates the correct thickness. This calibration will be correct for any measuring time interval since any change in the time interval changes both the duration of opening of AND gate 16 and the frequency division ratio of device 17 so that the same number of pulses are fed to the integrator. Amplifier 29, Fig.2 (not shown) is constructed to have four discrete characteristics selected by a switch which changes the input and output polarity and also inserts either a fixed resistor or a parallel network of diodes and resistors in the feedback path so that the characteristics of the amplifier follows the curve Y =A(e<SP>BX</SP>-l) where Y is layer thickness, x is the detector count and A and B are constants and this derived signal can be added to the input signal to provide a linear curve relating thickness Y and detector count x, Fig.4 (not shown).

Abstract: 861,911. Injection moulding. PROJECTILE & ENGINEERING CO. Ltd. Jan. 29, 1958 [Jan. 30, 1957], No. 3336/57. Class 87(2). A worm conveyer 17 is rotated in a plasticizing chamber 11 to force material therethrough, and the chamber 11 has a ram 30 thereon adapted to be forced into an injection chamber 31 to effect injection through a nozzle 32. In Fig. 1 the worm 17 forces material from the plasticizing chamber 11 into the chamber 31 through a passage 13 having a non-return ball valve 34, and thereby forces the ram 30 backwards, carrying with it the chamber 11 and worm 17. When sufficient material has been forced into chamber 31, the worm 17 stops. The ram 30, chamber 11 and worm 17 are then forced forwardly by means of a hydraulic piston 25. In a modification, Figs. 2, 3, injection is effected by forward movement of the ram 30, chamber 11 and worm 17 by means of a ram 51 in a cylinder 52, the worm 17 being simultaneously rotated by a drive motor 53 through a worm drive 54 and coupling 56. Cylinder 52 is secured in a crosshead 47 which is slidably mounted on a carriage 48. The crosshead 47 is connected by tie rods 45, 46 to cylinders 42, 43 containing double-acting rams 40, 41. Cylinders 42, 43 are mounted on a crosshead 44 which carries the chamber 31. After injection, the ram 30, chamber 11, worm 17 and carriage 48 are moved rearwardly by the pressure of material being fed to chamber 31 by worm 17. Finally rams 40, 41 are operated to move the injection chamber 31 away from the mould to break the sprue. Specification 799,672 is referred to.

A fluid pressure system comprises an open and a closed centre branch, orificed means movable to control flow from a fluid pressure source to said branches and responsive to variation from a predetermined flow through the orifice to the open centre branch to adjust the excess flow to the closed centre branch in the opposite sense, and other means for selectively directing the excess flow in response to the fluid pressure demands of the closed centre branch. Fluid flows from pump 5 driven by, e.g., a vehicle engine to port 31 where it acts via grooves 76, 77 on the end 75 of a plunger valve and flows at a predetermined rate via orifice 81, plunger passage 79, open end of the plunger and groove 28 to a port 33 leading to an open-centre fluidpressure system comprising open-centre servomotors 8, 13, 8 being a vehicle steering mechanism, and thence to sump 3. Should the flow rate increase, the plunger valve moves against spring 82 to throttle the flow at 28 and the excess fluid flows around a plunger land into groove 27 and past an annular spring-loaded relief piston 47 to charge an accumulator 15 in a closed centre fluid pressure system, e.g. servomotor 17 operating brakes 19. With the accumulator approaching fully charged condition, and pressures upstream at A and downstream of the valve 47 nearly equal, a shouldered relief valve 71 opens to bleed the pressure in chamber A through ports 59, 35 to sump via 22, so that valve 47 reseats on the end 52 of dumbell valve 50, and because the piston area formed by 47, 52 is greater than the area of end 54 of the dumbell valve, accumulation pressure on piston 47, 52 quickly opens valve 54 to discharge all excess flow to sump and valve 71 closes. A plunger operated relief valve also directly connects port 33 to sump port 35. Specification 897,541 is referred to.
