Title: Improvements in or relating to electrically tunable resonant circuit arrangements
IPC: H03B23/00
Filed: 1962-09-28
Abstract: 988,800. Frequency modulation ; testing radio apparatus; non-linear resistance networks. SIEMENS & HALSKE A.G. Sept. 28, 1962 [Sept. 29, 1961], No. 36831/62. Drawings to Specification. Headings H3R, H3U and H4L. An oscillator or tuned circuit is frequency modulated or tuned by applying a variable voltage between two oppositely directed capacitance diodes connected across the tuned circuit inductor to a centre tap of which back bias for the diodes is applied. To ensure linearity of the frequency modulation the variable voltage may be derived from a voltage divider in which the resistance of the upper (series) part is successively reduced by Zener diodes as a negative input voltage becomes more negative (thus giving a higher output ratio) and the resistance of the lower (shunt) part successively reduced by diodes conducting as the input becomes more positive (thus lowering the division ratio). In addition, resistors shunting the Zener diodes may be voltage dependent to increase the effect produced. Alternatively, the voltage divider may produce a logarithmic relation between voltage and frequency. In a modification variable resistors in series with diodes replaoe the Zener diodes and the resistors in series with the diodes of the shunt part are also variable.

Title: Improvements in or relating to injection moulding
IPC: B29C45/18
Filed: 1960-10-27
Abstract: 913,830. Injection moulding machines. HEHL, A., HEHL K., and HEHL E., [trading as ARBURG FEINGERAETEFABRIK OHG. HEHL & SOEHNE]. Oct. 27, 1960, No. 36917/60. Class 87(2).  A metering feed device in an injection moulding machine comprises a shutter 4 adapted to be operatively linked to the injection piston 6 to cut off or permit the feed of material into the injection cylinder (not shown) and an adjustable metering piston 14 which is reciprocated in a supply passage 19 on movement of the piston 6. During the injection stroke piston 6 and a member 7, carrying a spring loaded shutter 4 and a transverse pin 8, are moved down and the ends of the pin 8 contact the lower jaws of a pair of similarly shaped levers or catches, one lever 9 only being drawn in Fig. 1, which are rotated about their axles and cause a yoke 13 to force piston 14 and a stroke-adjusting device 15 inwardly. A measured quantity of material is thus forced up the adjustably inclined surface 12 into passage 29 which is closed by shutter 4. When the piston is moved upwardly, shutter 4 rises, material falls under gravity into the injection cylinder from passage 29, and pin 8 hits the upper jaws of catches and yoke 13 hits a screw 16 attached to piston 14 and moves it to the left so that new material enters chamber 19 from the hopper.

Abstract: 941,296. Vertical steam generators. FOSTER WHEELER Ltd. Oct. 2, 1962 [Oct. 9, 1961], No. 37376/62. Heading F4A. In a steam generator in which the heating surface is provided by tubes 16 disposed in a vertical shell 10 containing the water to be evaporated, the tubes being surrounded by a baffle 26, the space 30 within which forms a riser for the steam which passes to a steam space 44 at the upper end of the shell before leaving the shell through scrubbers 14 and an outlet 14 and wherein the space 28 between the baffle and the shell forms an annular downcomer for the water, there is provided within the downcomer baffle 26 a skirt 36 defining a passage 34 of reduced cross-section, which skirt defines with the baffle an open-topped channel 38 communicating with the downcomer space 28 through apertures 40 located below the working water level L. In operation, as the steam-water mixture ascends through the riser the restricted passage imposes on it a change of direction with consequent separation of water which is received by the channel 38 while the partially de-watered steam proceeds towards the steam outlet through apertures 42 in the top of the riser. In a modification, Figs. 2 and 3 (not shown), guide vanes are fitted in the restricted passage 34 to impart a whirling motion to the steam-water mixture to aid separation and a vertical centrifugal separator is connected to each of the apertures 42. Furthermore, to prevent the apertures 40 from being uncovered by fluctuating water level the skirt 36 extends inwardly from the baffle from a point well below the necked portion thereof. In a further modification, Fig. 4 (not shown), the skirt 36 is not connected to the baffle but extends downwards within the baffle to its lower end, providing a second annular downcomer space separated from the space 28 by the baffle.

Abstract: 1,022,589. Window or door operating system. K. W. M. PETERSEN. Sept. 26, 1963 [Sept. 27, 1962], No. 37853/63. Heading E2M. [Also in Division G3] In a system for moving a member, e.g. a door or, as shown, a window 1, between two positions by means of an hydraulic or pneumatic cylinder 2 supplied with pressure medium, which may be compressed air, under the control of a thermostat 6, two valves 9 and 19 are included in the pressure medium circuit and can be opened by a mechanical action derived from the movement of the window so as to determine the two extreme positions of the latter. As shown, a rod 37 is suspended from the window and carries a weight 43. Two stops 39 and 40 may be fixed at any desired height on the rod 37, and are operative through levers 29 and 30 to open the valves. When the thermostat 6 delivers pressure medium from supply 7 through pipe 5 to open the window, both valves are closed. When the stop 39 impinges on lever 29, valve 9 opens and the pressure in pipes 28 and 5 is relieved to arrest movement of the window. The pressure in the cylinder 2 is just sufficient to hold the window in this extreme position. When the thermostat, through aperture 44, further relieves the pressure in pipe 5, the window closes until stop 40 impinges on lever 30 to open valve 19, whereby pressure-medium is supplied via supply 7, valve 19 and pipes 28 and 5 to the cylinder 2 to arrest downward movement of the window and hold the latter in this extreme position. Eccentrics 31 and 32, to which the levers 29 and 30 are pivoted, may be rotated to provide a fine adjustment of the two extreme positions.
