Title: Fluid flow control valve assembly
Inventor: HOLLINGS JOHN SHAW
IPC: G21C9/004
Filed: 1961-11-30
Abstract: 941,273. Fluid-pressure servomotor control valves. ROLLS-ROYCE & ASSOCIATES Ltd. Nov. 30, 1961, No. 42972/61. Heading G3P. [Also in Division F2] A control valve of a servomotor comprises a floating valve member 32, (i.e. one which is not guided or connected to a member guided in a bearing) connected at one end to a bellows 33 and at its other end to a spring abutment member 41. A spring loads the valve member towards its seat 25 and at its other end bears against a flange of a member 37 which is provided with an aperture 40 of larger size than the valve member. The bellows 33 is secured to a boss 34 at a position nearer the valve seat than the other end of the spring and is preferably vented to atmosphere. The hydraulic pressure and spring may be such that the spring and bellows tend to return the valve member to the valve axis when the member is subjected to a transverse force. The valve is opened by fluid pressure upstream of a restriction 13 acting on the valve member and bellows and supplies fluid to act on a spring loaded piston 20 of a pressure relief valve 17, controlling the pressure of cooling water of a nuclear reactor 14.

Title: Improvements in or relating to regulating systems for rotary fluid operated power units

IPC: H02P23/00
Filed: 1960-12-16
Abstract: 930,557. Automatic control of turbines. ATELIERS DE CONSTRUCTIONS MECANIQUES DE VEVEY S.A. Dec. 16, 1960, No. 43408/60. Class 38 (4). A speed regulating system for a turbine comprises an element 4 for comparing a voltage representing the speed of the turbine with a reference voltage, the speed-error voltage being supplied to an element 9 which only provides an output signal if the error voltage is outside a predetermined range of values. Element 10 provides a signal which is a function of the difference between the amount of fuel supplied to the turbine and a reference value, said signal being applied to amplifier 5 for controlling motor 6 which regulates the rate of supply of fuel. The motor 6 operates until the rate of supply corresponds with the reference value. If the speederror signal exceeds a threshold value, the element 9 supplies a signal to the element 10 which causes the motor 6 to reduce the supply of fuel. As shown, if the speed-error signal Ue exceeds a bias voltage across points S, C, diode D2 conducts and current passes through resistor Rs to provide an output voltage Us for' application to element 10. Alternatively, diode D1 conducts if the voltage Ue becomes smaller than the bias voltage across points O, C.

IPC: B29C49/24
Filed: 1965-10-19
Abstract: 1,128,662. Mould labelling plastic articles. UNION CARBIDE CORP. 19 Oct., 1965, No. 44291/65. Heading B5A. A labelled moulded article, e.g. a blow moulded container, is produced by applying a charge of static electricity to the surface of a label and placing it against the wall of an empty mould cavity, introducing a heated thermoplastic material into the mould, forming the said article therein, and removing the article with the label adhered thereto. A patterned label is fed from a roll 12 to a back-up member 20 at which position the label is severed from the roll. The member has one or more wire probes connected to a high potential which charge the label, and passages therethrough from which compressed gas is ejected to blow the charged label on to a carrier head 22 which reciprocates between the member and a blow mould 14. An additional label is similarly charged and fed to a second carrier head so that each mould half receives a label. Each carrier head is perforated and its interior connected to both a compressed gas and a vacuum source; the latter to retain the label and the former to deliver it to the mould wall to which it adheres. The feed of the individual labels to the member 20 may be controlled by a photoelectric cell (18), Fig. 2 (not shown), and before reaching that member each label may be cut to shape by a trimming knife (28) and a backing plate (29). The label may comprise a film of ethylene, propylene, styrene or cellulosic polymer and the printing thereon may be on that surface which is to be fused to the container. Label texturing steps can be employed prior to the insertion of the label into the mould. The printed surface may be coated with an olefin polymer wax which has been reacted with a carboxylic reagent. Various constructions of carrier heads and label back-up members are described. The high voltage wire probes may be carried by the carrier heads.

Title: Teleprinter systems

Filed: 1973-09-26
Abstract: 1395856 Digital transmission; coding and synchronizing SIEMENS AG 26 Sept 1973 [4 Dec 1972] 44985/73 Heading H4P For the maintenance of synchronism between a teleprinter transmitter and receiver continuous start or stop levels are sent out as periodic n-bit characters. The remainder of the code, e.g. CCITT No. 2, plus start/stop is also converted to an n-bit arrangement. In one arrangement n=7 and teleprinter bits become bits 2-6 and remain unchanged, start= 0 except for certain function characters and bit 7 provides even parity which variations are set out in Table 1 in the Specification (not shown). A modified inverse arrangement is given in Table 3 (also not shown). At the receiver a reverse coder changes incoming signals to the original form. At the transmitter, on presentation of any 5- bit plus s/s signal, except all zeros, to terminals a-g, at least one of the inputs b-# is supplied with a 1 so that a 0 is emitted from at least one of outputs of inverters 26-30 to AND 40. This emits a 0 to inverter 32 thus passing a 1 to NAND 41 also receiving a 1 from gate 25, hence on receiving a shift pulse through terminal 14c output of 41#0 setting stage 51 of shift register 51-57 to 1 hence through inverter 33 a 0 on lead h. 0 Inputs to NAND gates 48, 49 give is to NAND gates 42-46 which are primed by shift pulses 14c hence if any of terminals b-# are also 0s on application of shift pulses 14c corresponding Is are passed into gates 52-56 and hence corresponding 0s at terminals i-m. Parity stage 58 senses output of stages 52-56 and an odd number of Os will produce a 1 on terminal n. Presentation of a start level, i.e. all 0s to terminals a-g causes all 1s inputs to AND 40 hence stages 51, 53 remain at 0 and leads h, j=1. The 1 to NAND 49 also receiving 1 from inverter 31 provides 0 inputs to gates 42, 44, 46 giving 1s on leads i, k, m. The 0 to NAND 48 provides a 1 to NAND 45 and hence a 0 at lead l. The even number of 0s into parity detector 58 provides a 0 on lead n thus the signal 1111010 is produced. Feed signal VOR 0000001 is coded into 1010100 and the stop level 1001111 is passed through unchanged. In Table 3, start, stop and VOR combinations are characterized by having a Hamming spacing of four. A test circuit is described in connection with Fig. 5 (not shown), which blocks temporarily the output of the start/stop signal generator if there is a transition from continuous start to continuous stop. Before passing to line, the combinations produced are converted by a convolutional coder (16) which on reception is passed through a convolutional decoder (18) neither forming part of the present invention. At the receiver, the reverse process takes place and in addition a check is made to ascertain whether signals representative of start/stop levels occur several times consecutively in order to provide terminus information.
