Filed: 1945-08-14
Abstract: 597,354. Milling-machines ; lathes. GARNETT, E. O. Aug. 14, 1945, No. 20947. [Class 83 (iii)] [Also in Group XXIII] A machine for forming curved surfaces includes a tool clamped to a plate mounted on supports for universal movement in one plane, a fixed spindle passing through a circular hole in the said plate and having a disc mounted thereon smaller in diameter than the said hole, and means for pressing the plate against the disc and moving the said plate round in Circumferential contact with the disc so that the point of the tool is moved in a circle or part of a circle having a diameter equal to the difference in diameter of the hole and the disc. A tool plate 6 with a diamond tool 24 on an extension 23 thereof is mounted on Compound slides 7, 3 guides by pads 10, 5 sliding in grooves 8, 4 and is formed with a circular hole 13, the circumference of which is kept in contact with a removable circular disc 15, mounted on a vertical fixed spindle 12 passing through the said hole, by means of a spring-pressed plunger 22 pressing on a cylindrical surface 18 of a plate 17 secured to the plate 6. Thus, as the plunger is rotated about the spindle 12 by means of a handle 27 turning a cap 19 containing the plunger and rotatably mounted on the spindle, the tool plate is given a gyratory motion causing the tool point to move in a small circle 28. The machine may be used in a lathe for cutting radii.

Title: Control vavle assemblies for vehicle hydraulic braking systems
IPC: B60T13/14
Filed: 1973-05-02
Abstract: 1416632 Brake boosters GIRLING Ltd 16 April 1974 [2 May 1973] 20948/73 Heading F2F In an hydraulic booster having a first nor-  mally open valve 17, 29 controlling communication between a reservoir connected radial passage 27 and a pressure space 26 located between a positively actuated piston 12 and a floating piston 19, and a second normally closed valve 34, 35 controlling communication between the pressure space 26 and a fluid pressure source, a valve operating member 28 is guided to slide in a bore in one of the pistons to permit the second valve to close and the first valve subsequently to open when the piston 12 is returned to an inoperative retracted position in response to pressure of fluid remaining in the pressure space when an applying force to piston 12 is relieved. In the construction shown valve operating member 28 slides in a bore 14 in piston 12 and has a head 29 adapted to engage seating member 17 provided in the bore. When piston 12 is advanced the seating member 17 engages head 29 to cut off communication between pressure space 26 and radial passage 27 through a radial passage 15. Thereafter valve operating member 28 advances with piston 12 and through a stem 30 extension 33 and head 32 causes a ball 34 to be lifted from a seating 35 to allow fluid pressure to be admitted into pressure space 26 for advancing piston 19 by way of a pipe 40 and bore 20. Pressure acting in space 26 on piston 12 provides a reaction force to a pedal operating piston 12, and when this pressure equals that of the source ball 34 engages seating 35 under the bias of a spring 36 and a balanced condition is reached. When the pedal operating force is relieved piston 19 is retracted by a spring 41 and pressure in pressure space 26 returns piston 12 to its retracted position taking member 28 with it until head 32 engages a stop member 31. Thereafter piston 12 moves relative to member 28 thereby lifting head 29 from seating member 17 to establish communication between pressure space 26 and the reservoir via passage 27. In a further construction the two valves have balls co-operating with seats in the respective piston, the seating of the first valve being provided in the second piston and the seating of the second valve being provided in the first piston, pressure fluid passing to the pressure space, upon actuation, through the first piston. In a further embodiment the valve heads are both provided on the valve operating member.

Filed: 1976-05-20
Abstract: 1507626 Scanning cine films THOMSON-CSF 20 May 1976 [23 May 1975] 20964/76 Heading H4F [Also in Division G3] In a film scanning arrangement where a cine film 4 is scanned by a spot of light, generated by a cathode ray tube 1 and focused by lens 2 and oscillating mirror 3, means are provided for monitoring the position of a frame marker, e.g. a perforation 40, said means comprising a light source, 80, for illuminating the marker, a photosensitive surface 12 for receiving an image of the marker, and means for directing said image onto said surface, wherein the light illuminating the marker passes through said lens and is reflected by said mirror. As described, the mirror 3 oscillates so as to follow the continuously moving film until a complete frame has been scanned, when it swings back to follow the subsequent frame. Light from lamp 80 should therefore continuously illuminate perforation 40, the image being reflected back through lens 2 by a strip of mirror 5 under the edge of the film. Beam splitter 10 directs the image through cylindrical lens 11 onto a photosensitive device 12 which generates a signal in circuitry, not shown, representative of the position of the perforation. This signal can be used to control the oscillating mirror 3 or the position of the raster scan in the c.r.t. 1. The video signal representative ofthe film image is generated in detector 7.

Title: Continuous process for making polymethylene terephthalate polymers
IPC: C08G63/00
Filed: 1965-05-19
Abstract: A continuous process for making polyalkylene terephthalates comprises continuously producing the polymer at a greater rate than is required while converting the excess polymer by reaction with the alkylene glycol used in the manufacture into a polymer precursor and <PICT:1082006/C3/1> recycling this precursor with polymer of substantially the same composition already in transit in the process. Terephthalic and ethylene glycol are fed to an esterification reactor 10 and the product (consisting mainly of bis-2-(hydroxyethyl)terephthalate) is fed to a prepolymerizer 15 from which the ethylene glycol is recycled and the prepolymer formed is passed to a final polymerizer 21.  The bulk of the final polymer from 21 is passed to an extrusion process whilst excess is passed to line 22 where it is reacted with ethylene glycol and (according to its composition) returned to the esterification reactor 10, the prepolymerizer 15 or the final polymerizer 18.  Ethylene glycol required for line 22 may be obtained from the final polymerizer 18 although additional amounts may be obtained from another source if necessary.

Title: Control device for radio receiver
IPC: H03J3/12
Filed: 1937-08-03
Abstract: 505,276. Wireless receiving circuits. MULLER, E. N. Aug. 3, 1937, No. 21440. Void. Convention date, Aug. 1, 1936. [Class 40 (v)] The invention relates to circuit arrangements for deriving control voltages actuating a utilization device of the kind described in Specification 500,111 or 503,217 whereby the receiver tuning shaft is arrested when exact timing with a desired station is obtained or the tuning gear ratio is changed thereby. An object of the invention is to prevent false actuation of the device by an interfering signal such as static. In Fig. 1, part of the output of the I.F. amplifier 5 of a superheterodyne receiver is applied to preliminary amplifiers 16, 19 and thence to a pair of rectifiers 46, 47 the outputs of which are applied in opposition to vary the bias on a D.C. amplifier 29 operating the utilization device 34. The input circuit 45 of rectifier 47 is flat-tuned to the I.F. and is magnetically coupled to circuit 41, while the input 43, 44 of rectifier 46 is sharply tuned and has a pronounced double-humped characteristic a few kc. on each side of the true I.F., by virtue of the series-resonant circuit 44. When a station is exactly tuned in the normal delay bias on 46 is exceeded, 46 then opposes 47 and the potential of line 50 falls to zero causing a sharp rise in the anode current of 29 which actuates device 34. An impulse due to static would not affect both circuits equally, as does a desired station, and the device would not be actuated. The amplifier 16 may be dispensed with and the circuits 43, 44 may be replaced by three parallel circuits connected in series in the anode circuit of valve 19, tuned respectively 2À5 kc. above, below and exactly to the I.F. ; the input of rectifier 47 is coupled to the first mentioned, 46 being connected to the common point of first and second, Fig. 2 (not shown). In Fig. 3, the rectifiers 46, 47 are fed from separate channels comprising amplifiers 193, 192. Their input circuit characteristics are as for Fig. 1, but the rectifier 46 opposes 47 by varying the grid bias of amplifier 192. The output of 47, as varied by 46, is applied to a D.C. amplifier 91, the anode circuit of which includes a neon tube 90. This tube strikes at a critical voltage corresponding to the in-tune position ; the resultant voltage drop across resistance 93 removes a prohibitive bias on the radio frequency amplifier 94 and renders the receiver and the A.F.C. system operative ; positive bias on 94 is prevented by the limiting diode 94<1>. The lamp 90 may also give a visual indication of tuning. The outputs of the two rectifiers 46, 47 mutually opposed, e.g. as in Figs. 1 and 2, may be applied to different grids of a hexode D.C. amplifier whose anode circuit includes a lamp such as 90, Fig. 3.
