Title: Method of converting heat into mechanical energy and vapour power plant for performing the method
IPC: F01K7/22
Filed: 1962-11-12
Abstract: 951,182. Power plant. SULZER FRERES S.A. Nov. 12, 1962 [Nov. 22, 1961], No. 42693/62. Heading F1Q. [Also in Division F4] The invention relates to a vapour (e.g. steam) power plant in which two cycles which are thermally connected are performed. The mass flow in the upper cycle is greater than the mass flow in the lower cycle and heat is supplied to the lower cycle in at least one superheater and/or reheater directly heated by combustion products in addition to the heat transferred from the upper cycle. In Fig. 2 superheated steam is distributed between a main turbine 7 and an auxiliary turbine 8 connected in parallel and is then collected and flows through a pipe 9 to a high pressure heat exchanger 10 and a medium pressure heat exchanger 11 connected in parallel. After the steam has given up some of its heat in the heat exchangers 10 and 11 to the lower cycle it is collected and flows through a further heat exchanger 12 and then enters a compressor 13 which compresses the steam and feeds it into the superheater 6. In the second cycle the working medium flows through the highpressure heat exchanger 10 into a flue-gasheated superheater 25 live steam leaving the superheater 25 flows to a high pressure turbine 26 from the latter to the medium pressure heat exchanger 11 and through a flue-gas-heated reheater 27 to a medium and low pressure turbine 28. In Fig. 6 the heat exchangers 10 and 12 are replaced by a mixing zone 15 and a branch point 14. In order to denote the working medium mixtures symbolically, the common flow formed by the mixed working medium streams from the two cycles is shown in black and white lines. Other modifications are described.

Title: Improvements in or relating to adjustable frequency dividers
IPC: H03K23/66
Filed: 1964-10-21
Abstract: 1,036,948. Electronic counters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 21, 1964 [Oct. 24, 1963], No. 42885/64. Heading G4A. Each binary-coded decimal stage of a multi-denominational adjustable frequency-divider operates to a code such that carry takes place at a representation other than conventional zero. The complement of the divider is set up on selectors 1SK- 5SK. When an output appears from the highest stage T5, the stages T3-T5 are reset immediately but T2 and T1 are reset sequentially, because of their faster rate of operation, only when each in turn has completed its cycle. The coding used is shown in Fig. 5. An alternative coding (Fig. 7, not shown) may be used.

Title: Means for controlling the emission of unburnt hydrocarbons from the engine of a motor vehicle
IPC: F02D9/02
Filed: 1969-08-28
Abstract: 1279279 Carburetters TOYOTA JIDOSHA KOGYO K K 28 Aug 1969 [3 Sept 1968] 43011/69 Heading F1B The discharge of unburnt hydrocarbons from a vehicle engine during deceleration is reduced by means of an abutment 14 which, when the vehicle speed is above a predetermined value, is moved into the path of a lever 6 connected to the throttle valve 4 to prevent the throttle valve from reaching its idling position. The throttle valve is thus held slightly more open than under idling conditions to permit a greater intake of air. The vehicle speed is sensed by a generator 21 driven by the speedometer drive cable 22 and generating an A. C. voltage proportional to the speed. The A, C, voltage is supplied to a circuit 23 wherein it is rectified and applied, via a Schmitt trigger, to operate a relay 24 when the vehicle speed exceeds a predetermined value. The relay controls a solenoid 27 to move a valve 30, to the position shown, in which the space 20 below a diaphragm 19 is vented to atmosphere via the air cleaner 35. This allows a spring 15 to move a lever 12 carrying the abutment 14 into the position shown. In addition, the valve 30 connect a vacuum take-off 11 to a device 39 for retarding the ignition timing of the distributor 37. A device 38 for advancing the ignition timing is permanently connected to a vacuum take-off 10. At large openings of the throttle valve 4, the take-off 10 is located downstream of the throttle valve, while the take-off 11 is located upstream of it. A high vacuum is then transmitted to the device 38 to advance the ignition timing. When the engine is decelerating with the throttle valve closed to the extent permitted by the abutment 14, the take-off 10 is then upstream of the throttle valve while the take-off is then downstream of it. A high vacuum is then transmitted to the device 39 to retard the ignition timing so as to increase the engine braking effect. At vehicle speeds below the predetermined value, the valve 30 occupies its alternative position, in which it connects the space 20 to the takeoff 11. When the throttle valve 4 is then closed sufficiently to bring the take-off 11 to a downstream position relative to the throttle valve, a high vacuum is communicated to the space 20 to cause the diaphragm 19 to lift the abutment 14 clear of the path of the lever 6 so that the throttle valve can close to the idling position. In addition, the valve 30 renders the device 39 inoperative by venting it to atmosphere via the air cleaner 35. The vacuum control of the ignition timing is then effected by the device 38 only. The diaphragm 18 may be replaced by a bellows or a plunger. The lever 12 may be operated through the intermediary of a solenoid controlled by a vacuum-operated switch. The lever 12 may be omitted, the abutment (40), Fig. 3 (not shown), then being carried directly by the spindle 17.

Abstract: 1,070,546. Recording-apparatus. M. GOLABEK. Oct. 22, 1964, No. 43062/64. Heading G1J. Spectrum lines projected from a film on to a screen are examined by moving a scale 15 (having a series of lines 16 each associated with an electrical circuit connected by a cable 12 to a recording-apparatus) across the screen to select the line 16 most closely resembling the density or width of the line under examination and then the associated circuit is closed to make the recording-apparatus record a symbol representative of the selected line 16. The apparatus 11 comprises a row of keys 13 on top of a case, enclosing a lead from each key 13 to the cable 12 and fixture 14 to receive the scale 15. After moving the apparatus 11, on its felt base, across the screen to match a line, the corresponding key 13 is pressed to complete the associated circuit and actuate an electrically operated typewriter. A blank key is provided for actuating the typewriter space bar between each symbol and a "minus" key is pressed when the substance examined spectroscopically shows no specific element. In a modified apparatus after selecting the line 16 the scale 15 is moved relative to a single key to close a circuit associated with the selected line.

Abstract: 1,071,787. Sawing. L. STRIEBIG. Oct. 30, 1964 [April 23, 1964], No. 44303/64. Heading B5L. A sawing jig for cutting building panels of major size to shape and for cutting rectangular openings in the same comprises an upright frame 10 having a horizontal frame member 13 provided with carriers 16 for supporting the panel to be cut, a roller carriage 17 guided along an upper horizontal frame member, a guide beam 18 extending vertically downwards from the carriage, a slide 19 on the guide beam provided with locating means and carrying a deflectably mounted circular saw 20 which is also tiltable from a position for making vertical cuts to a position for making a horizontal cut, and support means on the front face of the frame for supporting a panel resting on the carriers comprising an elevationally movable trellis which has horizontal battens 24 and is positively raisable in the plane of the trellis by motion transmitting means 31 operably by inward deflection of the saw for making horizontal cuts whenever the blade of the saw is in elevational alignment with a batten of the trellis and could damage the same when making the cut. The circular saw is tiltable by a handle 22 between the positions for making the horizontal and vertical cuts and is clampable in position on the slide 19 by a locking lever 21. In the position for making horizontal cuts, the blade 20a of the saw is laterally slightly offset from the panel surface and the saw is deflectable inwards by a handle 23. When making horizontal cuts the guide beam 18, which extends from the roller carriage 17 and is supported by the lower rail 13, is movable transversely of the frame 10, and for vertical cuts, the slide 19 movable vertically in the guide beam which is locked in predetermined positions in which the saw blade is aligned with vertical slots in the horizontal battens so as not to damage the battens. The top member of the trellis consists of an inverted U-section rail 26, one flange of which is engaged by a roller 27 on an arm 28a extending from a lifting bar guided for movement in a rail 29 secured to the beam. The bar is provided with pairs of projections 30, the projection of each pair being spaced a distance corresponding to the spacing of the flanges of the battens and the spacing of the pairs of projections being equal to the spacing of the battens. A quadrant 32 is pivotally mounted on the slide 19 and has a recess receiving one end of a lifting finger 31 which is normally disposed in an inoperative position and held on the quadrant by a retainer. When the saw 20 is deflected by the handle 23 for effecting horizontal cuts, a bulbous projection 38 on the saw casing engages and rocks the quadrant to urge the finger 31 against the lifting bar. If the blade of the saw is in an elevational position in which it would engage and damage a batten 24 of the trellis, the finger 31 engages a projection 30 to raise the bar 28 and hence, by means of the roller 27 and rail 26, raise the trellis so that the batten is moved from the path of the saw blade.
