Title: Gas turbine engine
Inventor: WILKINSON WILFRED HENRY
IPC: F02K1/40
Filed: 1966-06-17
Abstract: 1,127,826. Gas turbine engine exhaust nozzles. ROLLS-ROYCE Ltd. June 9, 1967 [ June 17, 1966], No. 27150/66. Headings FIG, F1J and F1T.  A gas turbine engine has a plurality of exhaust nozzles which are angularly spaced apart in an annular array, each exhaust nozzle being non- rigidly connected to casing structure of the engine by locating means, whereby the transmission of bending stresses from the casing structure to each exhaust nozzle is reduced. In the engine shown the turbine is indicated at 13 in Fig. 2, the assembly comprising an outer casing 14 and an inner casing 16, a further casing 15 being disposed around the outer casing 14. An exhaust cone 30 having a peripheral flange 31 is secured to the inner casing 16 by bolts 29, the peripheral flange 31 defining with the inner casing 16 a circumferential recess 33. A series of plate members 23 are secured by means of bolts 24 to the outer casing 14 and further casing 15, the plate members defining with the casing 14 a series of circumferential recesses 26. A series of exhaust nozzles 20 are mounted to receive the exhaust gases from the turbine 13, the nozzles being of generally elleptical form and having at their forward ends radially inner and radially outer flanges 22, 21, the flanges 22, 21, being. received within the circumferential recesses 33, 26, all respectively. Reeesses 45 in adjacent exhaust nozzles 20 co-operate to form a gap in which asbestos or other packing material 46 is received. Radially extending pipes 35 pass through openings in the downstream ends of the plate members 23, in the flanges 42 which are formed integrally with the peripheral flange 31, and in the exhaust cone 30, whereby air under pressure may be supplied to the interior of the exhaust cone for cooling purposes. Springs 34 are disposed between the downstream ends of the exhaust nozzles 20 for tranmission of loads therebetween.

Title: Improvements in or relating to Control Apparatus for Electric Cookers.
IPC: H05B1/02
Filed: 1967-06-13
Abstract: 1,190,615. Control systems for cooking apparatus. SIEMENS - ELECTROGERATE G.m.b.H. 13 June, 1967 [28 June, 1966], No. 27331/67. Heading H2H. A control system for an electric oven or cooker comprises means whereby the oven or cooker is controlled for a predetermined period at a first pre-set temperature and thereafter may be controlled at a second pre-set, lower temperature. If desired, the period of the second temperature can be terminated by an automatic timer device. A control unit 5 comprising a selector switch 51, a timecontrolled switch 52 and a temperaturedependent switch 53 is connected between points AB in one of the leads between a supply RO and a heating element 1 of an oven, the control system further including an automatic timer device 4, an adjustable temperaturedependent switch 3 and a selector switch 2. The selector switch 51, in the position shown, allows the system to be controlled by the ON-OFF operation of the switch 3, set to, e.g. 220‹ C., the heating elements 1 in use being selected by the switch 2. When it is desired that a long period of cooking is required the switch 51 is manually operated to its changeover position which movement simultaneously closes switch 52. The system now operates initially under the control of the switch 3 at a high temperature until the time-controlled switch 52 opens after a predetermined period. With the switch 52 open control of the system passes to the switch 53 which is set, e.g. at 80‹ C., whereupon the oven is controlled at this lower temperature until switched off, either manually or by the automatic timer device 4. In a second embodiment a further temperaturedependent switch is provided which is utilized in lieu of the temperature-dependent switch 3 when the selector switch is operated to select the long period mode of cooking.

Title: Improvements in vending systems
IPC: G07G1/00
Filed: 1947-10-14
Abstract: 691,521. Coin-freed machines delivering selections of articles at different prices. PUNCH ENGINEERING PTY., Ltd. Oct. 14, 1947 [Oct. 14, 1946], No. 27547/47. Classes 27 and 116 [Also in Group XIX] Comparing total price with total coin insertion. A system for vending articles has means for adding the values of articles selected for delivery and a coin-operated device to totalize the value of inserted coins which permits delivery of the selected articles if the amount inserted is sufficient. A cash register may replace the coinoperated device. Articles are selected from shelves 1 by successive actuations of corresponding push-buttons 8, the selected articles passing to a conveyer 5 which delivers them to a normally stationary conveyer 6 for retention pending payment. Each button 8, when actuated, positions a hunting price switch 7 according to the price of the article (which can be pre-adjusted in a control assembly 4) and switches 11 and 12 are correspondingly positioned, whereupon the price switch 7 returns to zero ready for the next button actuation. Switches 11 and 12 take account of pence and shillings respectively in the prices and are interconnected by transfer mechanism 39; their movements are additive so that their final position corresponds to the total cost of the transaction. Coins then inserted in payment trip switches 21, 22 and 23 which, through control mechanisms 25, 40, step-up pence and shillings payment switches 26, 27 to positions corresponding to the amount paid in. If these positions correspond to those of the price switches 11, 12, a motor 29 is energized to drive the conveyer 6 to deliver the articles into shoot 30 and to the customer. Otherwise, and after a time delay, the motor runs in reverse to deliver the articles into a hopper 31 inside the apparatus; this also happens if the customer operates a "cancel" key 38. The buttons 8 are locked whilst the switches 7, 11 and 12 are responding to a previously actuated button. Alternatively, their circuits may be temporarily broken and a warning light 37 shown. In another alternative, the selections are stored in the control assembly 4 to be dealt with in turn by the price switches and in such an arrangement the conveyer 6 may run continuously and the selected articles remain on the storage shelves until paid for. As described in Specification 641,494, indicating lamps show progressively the price to be paid for the articles selected. The apparatus may be controlled by a cash register operating the mechanisms 25, 40 instead of by the coin mechanism shown. Coin-discharging mechanism; returning coins. After actuating the switches 21, 22 and 23, the inserted coins collect in a tray 32 which finally tips them either into the till 33 or into a return shoot 34 according to the direction the motor 29 runs and whether the articles are delivered or not.

The plate 16 has a locating tongue 23 engaging an aperture 22 in the blade 17. The earth socket comprises a U-shaped stamping 25 the limbs 24 of which have resilient tongues 29 punched from them to engage frictionally the walls of an opening 30 in the base 6. The centre part of the U is secured to a channel 26 positioned in a groove 27 in the base 6 and carrying a terminal 28, the channel, base and cover being secured by screws 31.

Title: Improvements in or relating to a Reservoir for Gas Under Pressure Having a Wall or Neck of Plastics Material in which is fixed a Valve Case of Harder Material
IPC: F23Q2/16
Filed: 1968-06-11
Abstract: 1,193,792. Pipe couplings. FLAMINAIRE MARCEL QUERCIA. 11 June, 1968 [13 June, 1967], No. 27674/68. Heading F2G. A reservoir for gas under pressure has a wall or neck 1 of plastics material and fixed therein a valve case 2 through which gas under pressure can be introduced into or allowed to escape from the reservoir, the case being made of a material harder than that of the plastics material and caught in the wall or neck by at least one projection 3 of sawtooth form and directed radially and extending in the axial direction of the case. The projection penetrates into the surface of the hole in the wall or neck to prevent the case from turning in the hole or from being retracted axially from the hole in a direction opposite to that in which the case was inserted by force into the hole. As shown, the case has spaced ribs 3 forming V-shaped grooves 7 and a conical portion 5 terminating in a cutting edge 9 which penetrates into a shoulder 10 to provide a fluid seal. Material of the wall or neck is displaced behind facets 8 to oppose axial separation of the case from the wall or neck. A further fluid seal is formed by the edge 11 of a collar 12, and a valve 15 carrying a seal 16 is biased by a spring 17 on to a seating 18. In a modification, the case has a chamfered circumferential collar the circular edge of which penetrates into the material of the wall or neck when the case is forced thereinto from inside the container.
