Title: Steam power plants
IPC: F01K7/24
Filed: 1960-10-04
Abstract: 884,358. Disposal of steam boiler blow-off. SULZER FRERES S.A. Oct. 4, 1960 [Oct. 15, 1959], No. 34037/60. Class 123(2) In a steam power plant where a by-pass pipe 47, branching off between a superheater 2 and a prime mover 3, is fitted with a valve 24 operable in dependence upon the operating condition of the working medium the by-pass valve is influenced by a signal which depends upon the flow of working medium through the superheater 2. In normal operation all of the steam generated in an evaporator 1 and passing through the superheater is fed, through a steam pipe 40 and a valve 12, to a high-pressure turbine section 3 partially expanded steam then flowing through a pipe 42 to an intermediate reheating superheater 4 leading through a valve 13 to a low pressure turbine section 5. The pressure drop across the superheater 2 is sufficient to maintain the piston rod of a piston 20, in a pressure sensing cylinder connected across the superheater 2, withdrawn from one end of a lever 23 the other end of which is connected to a spring balanced spindle 61 maintaining the valve 24 in the by-pass pipe 47 in the closed position. Since there is no pressure drop in throttles 25, 29, situated respectively in the by-pass pipe 47 and in a serially connected bypass pipe 47<SP>1</SP>, a valve 30 controlling the latter is also closed so that no steam by-passes either of the sections 3, 5. If the flow through the superheater is reduced, e.g. by adjustment of the valves 12, 13, the piston 20 is moved to the right, as the result of the reduced pressure drop across the superheater 2, so that its piston rod urges the lever 23 in a direction to open the valve 24 and allow steam to enter the by-pass pipe 47. The steam flow in the by-pass produces a pressure drop at the throttle 25 which is transferred, through pipes 64, 65, to a piston 66 to open the valve 30 a piston valve 26 in the line 64 being opened by the movement of a lever 57 connected to the rod of the piston 20. The lever 57 is connected at its upper end to the rod 59 of a piston 22 which slides in a cylinder having connection with a pressure signal line 21 leading, e.g. to a load controller, not shown. Feedwater or condensate is drawn respectively through Venturi tubes 49, 33 from storage and condensate tanks 72, 34 the tank 34 being supplied with water through a pipe 52 having a valve 53 which is influenced by a regulator 54 in dependence upon the water level in the tank 34. Added steam in the by-pass 47<SP>1</SP> due to independent operation of the valve 13 is sensed by the throttle 29 which, through a piston and cylinder unit 27, 68, further adjusts the valve 30.

Title: Improvements in or relating to television receivers
Inventor: CLARKE RONALD LESLIE
IPC: H04N5/645
Filed: 1956-11-08
Abstract: 809,876. Television. COLE Ltd., E. K., and CLARKE, R. L. Nov. 8, 1957 [Nov. 8, 1956], No. 34098/56. Class 40 (3). [Also in Group XL (c)] The cathode-ray tube 1, Fig. 1, of a television receiver is located and supported within a cabinet 6-9 by a plurality of pressure exerting devices 2-5 which are secured to the cabinet structure and exert pressure resiliently against the peripheral wall of the tube close to the front face thereof. Each pressure-exerting device may be constructed as shown in side elevation in Fig. 3 in the form of a bracket structure 11, 13 carrying a wedge member 15 which is adjustable in position (vertically in Fig. 3) by rotation of a screw-threaded rod 14, the wedge member exerting pressure against the inclined surface of a further wedge member 16 so as to displace it horizontally into engagement with the wall 18 of the cathode-ray tube. Wedge member 16 carries on its front face a resilient pad 17 of rubber of like material and is guided in its displacement by projections engaging the lower limb of bracket member 13. If desired, only two of the devices may be adjustable as shown in Fig. 3, the remainder being fixed blocks.
Patent GB-813720-A (GB)
Title: Improvements in magnetic tape reading system
IPC: G06F3/06
Filed: 1957-11-01
Abstract: 813,720. Electric digital-data-storage apparatus. GENERAL ELECTRIC CO. Nov. 1, 1957 [Nov. 5, 1956], No. 34159/57. Class 106 (1). [Also in Group XVI] The read-out of data from a magnetic tape into a utilization apparatus is controlled by recording a mark on the tape where data reading was discontinued in response to a first signal from the apparatus, reversing the tape to a position prior to where reading was discontinued, continuing the forward motion in response to a second signal from the apparatus and commencing the read-out of data into the apparatus when the magnetic mark is reached. The invention is described for printing out the data recorded on a tape by means of a highspeed printer 14 of the type having an associated register 16 to hold the data to be printed. An initiating signal source 30 supplies a start signal to the tape drive unit 10 and to a programmer 12. Read-out is commenced on a start signal code pattern being sensed by reading heads 20, this pattern being detected by the senser 34 which supplies a signal to the grogrammer 12, or alternatively by a mark on a special marker track being sensed by the reading head 22 which applies a signal to the programmer 12 through an AND gate 42 opened when the tape is being driven forward. The programmer 12 then supplies a " read " signal and data is read from the tape to the printer register 16 which provides an output when it is full to the programmer 12 which applies a signal to a singleshot multivibrator 44 to stop and reverse the tape and record a mark on the marker track by supplying a signal to a write amplifier 46. The output of the multivibrator 44 also sets a flipflop 50 to turn on an oscillator 51 which causes the head 22 to commence erasing and further supplies a signal to the printer 14 which then commences to print out the data in its register 16. When the tape has been stopped, the tape drive unit 10 supplies a signal to the AND gate 52 and the flip-flop 50 is reset. The tape now commences to traverse backwards, but erasure on the marker track no longer occurs, so that when the mark just recorded is read, a signal is applied via an AND gate 54 open when the tape is reversely driven to stop the tape drive and set the flip-flop 50 so that erasure recommences to erase any previously recorded marker pulse as the tape coasts to a stop. When the tape stops, the flip-flop 50 is reset. When the printer 14 has finished printing the data in its register it applies a signal to the programmer 12 which provides an output to the OR gate 32 to commence forward drive of the tape, and on the recorded mark being sensed, an output via the AND gate 42 causes the programmer to open the AND gate 24 thereby enabling data again to be transferred from the tape to the printer register 16. Provision may be made for delaying the stopping of the tape until an old marker pulse has been erased, by the insertion of a suitable delay in the tape drive unit. The programmer 12 (Fig. 2, not shown) comprises a sequence control unit of the type described and claimed in Specification 767,431.

Title: Improvements in steering gear
Inventor: BRADFIELD ALAN HERBERT EDWARD
IPC: B62D3/02
Filed: 1954-11-25
Abstract: 797,350. Cam steering mechanism. CAM GEARS, Ltd. Oct. 20, 1955 [Nov. 25, 1954], No. 34259/54. Class 80 (3). In vehicle steering gear wherein a cam 4 engages one or more followers 3 mounted in roller bearings 5 in a rocker arm 1, a freewheel device comprising rollers 8 allows the follower 3 to rotate freely in the direction corresponding to when the cam is driving the follower but prevents reverse rotation of the follower 3 in order to increase the friction in the gear when the follower drives the cam and thus damp the transmission of road shocks back through the the gear. The bearing rollers 5 are mounted in a housing 6 secured in the arm 1 and are axially held by a non-rotatable flanged ring 9 which surrounds the freewheel balls or rollers 8. The latter are located in tapered recesses formed by flats on the follower peg 3, and may be spring- loaded. In a modification the freewheel rollers 8 engage an extension of the housing 6 and are spaced from the bearing rollers 5 by a separator ring. In power steering gear the freewheel is arranged to operate in the reverse direction so that the increased friction is employed to damp the power steering.

Title: Improvements in or relating to electromagnetically operated gas valves
IPC: F16K31/08
Filed: 1935-12-11
Abstract: 467,340. Electrically-operated valves. HORSTMANN, B. G., and HORSTMANN GEAR CO., Ltd. Dec. 11, 1935, No. 34350. [Class 135] [Also in Group XXXVII] An electromagneticallyoperated gas valve comprises a lift valve member 4 attached to a horseshoeshaped or U-shaped permanent magnet 7 slidable within the valve casing 1 in a fixed guide 8 to which an electromagnet 9 is adjustably fixed, the valve being opened by the attraction of the magnet 7 by the electromagnet due to a momentary current in one direction and closed on reversal of the current. As shown a spherical lift valve 4 controls the inlet 2 of a casing 1 through which gas passes to an outlet 3. The valve may be loaded to close by a light spring in addition to the weight of the magnet 7. When the valve is closed, the air gap between the magnets is sufficient to prevent the valve being opened by the attractive force of the magnet 7 when the electromagnet is deenergized. On exciting the magnet 9 however by passing a momentary-current in one direction, the magnets remain in contact until a momentary current is passed through the winding 11 in the opposite direction. The ends of the winding 11 are connected to terminals on a block 14. The valve is remotely controlled by a reversing switch Fig. 5, comprising a base 15, a cover 16 and a pair of press buttons 17, 18 pivotally mounted on the ends of a lever 19 loaded by a tumbler spring 22. The press buttons which are of insulating material each engage one end of two U-shaped spring contact blades 23 connected by terminals 24 to a source of current. The blades 23 are sufficiently resilient to move away from contacts 25 connected to the winding 11 when either of the buttons is released. One of the buttons however remains depressed as shown to indicate the state of the valve. An additional contact 26 is provided to excite an ignition device 27 when the valve is opened. The valve 4 may be byepassed by means of a hand-operated cock 5 and a passage 6.
