Title: Improvements in shell and tube heat exchangers
Inventor: PEARCE ROY GEORGE
IPC: F28D7/16
Filed: 1967-06-15
Abstract: 1,212,526. Tubular heat exchangers; boilers. FOSTER WHEELER JOHN BROWN BOILERS Ltd. 14 June, 1968 [15 June, 1967], No. 27761/67. Headings F4A and F4S. In a tubular heat exchanger in which a high temperature fluid (e.g. hot gas at 2300 F.) flows through tubes 14 from an inlet header 20 defined in part by a tube plate 16, impingement of the hot fluid stream directly on to the tube plate 16 is prevented by a fluid-cooled shield plate 22 positioned in front of the tube plate and so arranged that both sides of the shield plate are subjected to substantially identical pressures. Hence the shield plate can be of relatively thin material and in an apparatus in which the temperature and pressure differences in the heat exchanging fluids are high, the stresses in the tube plate material are reduced. As shown, the shield plate 22 is hollow and cooling fluid is conveyed to and from the plate by way of conduits 34 (only one being shown). The shield plate is spaced from the tube plate 16 and this space 32 may be empty or the plate 16 can be provided with a thin layer ofinsulating or refractory material. Stub tubes 30 extend through the shield plate to convey the hot gas into the heat exchange tubes 14. The peripheral wall of the header is defined by the casing 10 of the heat exchanger and is lined with a refractory material 42 shaped to locate the shield plate. Alternatively the shield plate may be attached to the inner periphery of the shell 10 by a flexible sealing device. The shield plate cooling fluid may be water which is vaporized in the shield plate to provide a useful auxiliary supply of steam. In the event that the external fluid 18 is water some of this may be utilized as the shield plate cooling fluid.

Title: Safety device for protecting against theft for motor vehicles and aircraft
IPC: B60R25/10
Filed: 1933-10-09
Abstract: 414,243. Starting prime movers. GROB, W., 3, Staffelstrasse, Stuttgart, Germany. Oct. 9, 1933, No. 27775. [Class 38 (iv).] In automatic devices for the protection of motor vehicles against theft, the alarm circuit is automatically set on stopping the vehicle. A relay influencing a switch in the circuit of the starter or of the ignition coil and also of the alarm devices is arranged in a switching-in circuit adapted to be closed by the battery switch and again opened by a switch of a second holding relay. This switching-in circuit is controlled by a secret switch. The device comprises visible and audible alarms E<1>, E, a concealed press-button switch G and three relays I, II, III, the relay I opening a switch i and closing switches g, h, while the relay II opens switches m, o and closes a switch n, and the relay III closes a switch q. The relay I influencing the switches h, i in the operating circuits of the alarms and of the starter F or of the ignition coil is inserted in a switching-in circuit adapted to be closed by the battery switch D<1> and to be opened again by the holding relay II, which is energized by the action of the relay III receiving current simultaneously with the relay I. The relays I, II are automatically held switched-in by means of the closed switches g, n. If the switching-out press-button G is now actuated, the circuit of the relay I is cut out and the switches g, hare opened, and the switch i closes again, while the relay II remains under current and the switch m remains open, so that a switching-in of the relay I does not take place even when the button G is released. Thus, the alarm circuit is interrupted, and the starter circuit is closed by the switch i, the starter button F<1> being now effective. The visible alarm may be a lamp lighting the word " Theft " on a transparency.

Title: Improvements in or relating to electrical arrangements for converting from cartesian into polar co-ordinates
IPC: F41G3/26
Filed: 1945-10-24
Abstract: 618,421. Electric co-ordinate converters. DEHMEL, R. C. Oct. 24, 1945, No. 28041. Convention date, Oct. 25, 1944. [Class 40 (i)] Voltages representing the Cartesian coordinates of a point in a plane are applied to an electromagnetic device from which are inductively derived voltages corresponding to the equivalent polar co-ordinates. The invention is applicable to course charting devices for ships or aircraft or other moving objects. As applied to an aircraft trainer, sliders 33, 34, actuated by the trainer, take off from potentiometers 3, 4, energized from a transformer TR, voltages Ex, Ey, proportional to the x, y, Cartesian position co-ordinates of the simulated aircraft represented by the point 1 on the chart 5. The voltages Ex, Ey, which may be otherwise derived from the trainer are fed to the fixed quadrature windings 26, 26<SP>1</SP> of a rotary transformer 9 so that the secondary quadrature windings 25, 25<SP>1</SP> rotatable with the shaft 2 have voltages E#, Er induced therein representing the azimuth angle # and the range R multiplied by a factor dependent on the angular setting of the rotor. Voltage E# is fed through slip ring 28, brush 27, and amplifier 10 to the winding 29<SP>1</SP> of a two-phase servomotor 12, the other phase winding 29 of which is fed from the reference source e supplying the transformer TR. The servomotor rotates the chart 5 and the rotor 2 of transformer 9 through gearing 22, 23, 7, 8 until the rotor 2 and therefore the chart 5 take up an angular position corresponding to #, when E # is zero, or some other reference value dependent on bias applied to the amplifier 10. A second servomotor 16 has one winding 30 energized from the reference source and the other winding 30<SP>1</SP> energized through an amplifier 18 by the voltage Er. Motor 16 rotates the lead screw 15 to move the " range " nut 14 until the voltage Er is balanced in amplifier 18 by the voltage applied thereto by wiper 14<SP>1</SP>, moving with the nut 14, and derived from potentiometer 19 fed from a source of instant phase opposition to Er. The nut 14 thus moves the stylus 13 over the chart 5 according to the polar range R. The signalling elements 36, 38 of the trainer are driven from the azimuth and range elements 5, 14 respectively. Hunting of the servos may be prevented by velocity feed-back. The primary and secondary windings of transformer 9 may be reversed. D.C. motors may be used in lieu of the A.C. servos 12, 16 in which case the amplifiers 10, 18 must of course include demodulators. Specification 458,274 is referred to.

The positive clutch described in Specification 778,888 is modified by providing synchronizing means. Change-speed wheels 2, 3 are freely mounted on an output shaft 5 and are clutched thereto by pins 16 slidable axially in grooves in a sleeve 18 which is slidably splined to a carrier 8 fast with the output shaft. The sleeve 18 is formed with synchronizing friction clutch cones 32, 33 engageable with friction cones 35, 36 formed on the wheels 2, 3 and is coupled to the pins 16 by spring-loaded balls 42, so that when the pins are shifted by means of a collar 22 to clutch one of the wheels to the shaft, the friction cones 32, 35 or 33, 36 first engage to synchronize the wheel and shaft, and then the balls 42 yield and the pins engage recesses 25 or 26 in the wheels to positively clutch them to the shaft. The balls 42 engage recesses 48, 49 in the pins to locate them in their clutching positions. It is not necessary that every pin be coupled to the shaft by a spring-pressed ball 42, only one pin in three need be so coupled. The springs may be of the plate or of the helical type.

Title: Improvements in or relating to sheet feeding mechanisms
Inventor: SCHONE HELMUT
IPC: B65H7/18
Filed: 1964-07-08
Abstract: 1,068,570. Feeding sheets. DRUCK-MASCHINENWERK PLANETA VEB. July 8, 1964, No. 28130/64. Heading B6B. In apparatus wherein sheets, which are registered on a feed table 35 by front stops 13 assisted by upper limit stops 12, are fed by oscillating grippers 18 to a printing machine, a scanning means of known type can detect whether the front edge of each sheet is accurately registered, or two sheets are superposed, and will stop the sheet or sheets being fed from the table by preventing the grippers from closing on a sheet and ensuring that the stops 12, 13 remain in blocking position. In normal operation, the electric mains is connected with a magnet 1 which pulls a control lever 5 to the left, by means of a toggle 2 and rod 3, against the action of a spring 4, and thus rocks a locking shaft 6 to which is secured an arcuate cam 7. Locking levers 8 and 9 loosely mounted on the shaft 6 have a spring connection with the control lever 5, and are also moved to the left. The levers 8, 9, and the cam 7, are thus disconnected, respectively, from pawl levers 15, 16, 17, belonging to the drive of the stops 12, 13, and the oscillating grippers 18. If the scanning means stops the current to the magnet 1, the control lever 5 swings back to the full line position, and the pawl levers 15, 16, 17 are then operative to retain the stops 12, 13 in the raised sheet blocking position, and to hold the grip. pers 18 open, so that a sheet cannot be fed from the table 35. The movements of the stops and grippers is derived from rotating cams 28, 29, 30, and appropriate linkages.
