Title: Improvements relating to rotary actuators
Inventor: HORTON PETER
IPC: F16K31/05
Filed: 1968-09-20
Abstract: 1,272,563. Clutch control. ENGLISH ELECTRIC CO. Ltd. 16 Sept., 1969 [20 Sept., 1968], No. 44725/68. Heading F2L. A sliding clutch sleeve 14 is axially movable to connect alternative power 10 and manual 18 inputs to a common output shaft 12, e.g. controlling a valve, by means of a fork 24 engaging the sleeve and moved upwards against a spring 22 by rotation of a cam 46 by a lever 40, and is retained in its upper position engaging the manual input by means of a latch 38 pivoted on a vertical post 28 parallel to the clutch sleeve axis. The latch is spring-biased to a central position abutting a pin 32 on the fork 24. On starting a motor driving the power input worm-wheel 10, a surface 54 on the wheel coacts with a bevel surface 52 on the latch to rotate the latch so that the pin 32 drops into a hole 34 or 36 on the latch to allow the fork to drop and engage the power clutch 16. Again, Figs. 3 and 4 (not shown), the fork is replaced by a ring (58) carrying two diametrically opposed pins (66) engaging the sleeve 14, and pivoted on its side diametrically opposite the post 28 on an adjustable pin and flange (60), (64). The ring is pivoted by a lever (70) acting through a crank (72) on a member (68) supporting the ring and slidable on the post 28.

Title: Voltage and current regulators
IPC: G05F1/573
Filed: 1961-12-14
Abstract: 1,009,205. Protective systems for voltage regulators. WESTERN ELECTRIC CO, Inc. Dec. 14, 1961 [Dec. 15, 1960], No. 44746/61. Heading G3R. The series transistor of a voltage stabilizer is protected from transient overloading due to discharge of the reservoir capacitor 7 when the output is short circuited, by connecting a capacitor across the transistor through a biased diode. A transistor 1 is connected in series between a supply rectifier 8 and load terminals 14, 15, and is normally controlled to stabilize the voltage at 14, 15 by a Zener diode 10 and comparator transistor 11. A capacitor 2 is connected in series with a diode 3 across the transistor 1, the diode 3 being back-biased by a potential divider 5, 6. On short circuit diode 3 conducts diverting the discharge energy of capacitor 7 into capacitor 2 which charges slowly until the fuse 4 "blows".

Title: Improvements in or relating to the treatment and oxidation of a melt obtained from waste lyes
Inventor: BORISEK RUDOLF
IPC: C01D5/00
Filed: 1961-12-14
Abstract: A melt of sodium sulphide and carbonate is obtained by combustion, based on a reducing process, of sodium sulphite and bisulphite waste lyes and in order to oxidize the sodium sulphide to sulphate, the liquid melt is pulverized or atomized at 700 DEG -900 DEG C. after flowing out from a recovery unit, by a current of steam or steam and water at 2-15 atmospheres, the coarser particles are separated in a cyclone, ground in a pulverizing mill and fed separately or with the fine fraction, e.g. 80-90% and the atomization steam at 200 DEG -400 DEG C. to an oxidation system with cold moist air so as to maintain in the reactor a temperature of 130 DEG -250 DEG C. without further heat being fed into the reactor.  The melt may be granulated on a grid at 400 DEG -600 DEG C., fed into the pulverizing mill and then fed at 200 DEG -400 DEG C. into the reactor for oxidation.  The melt is produced from waste lyes, from the production of cellulose or hemicellulose by the sulphite process, which are condensed and calcined.

Title: Electrical heating apparatus
IPC: G05D23/24
Filed: 1970-12-15
Abstract: 1338376 Automatic control of temperature ELECTRICITY COUNCIL 15 Dec 1970 [15 Sept 1969] 45426/69 Heading G3R Electrical heating apparatus comprises a resistive heating element 10 connected in series with a switch 11 between supply terminals 12, 13, a heater 14 having a thermal time constant equal to that of the heating element and energized via the switch, a transducer 15 responsive to the temperature of the heater for providing an output signal and a control circuit responsive to the output signal for closing the switch when the output signal is below a predetermined value. The heating element 10 may be part of a furnace or an electric cooker in the bottom of which the heater 14 is located. The transducer 15 is a thermistor connected in a bridge circuit which includes a potentiometer 21 for setting the temperature at which the heating element 10 is to be stabilized. When the temperature is below the pre-set value a transistor 23 maintains transistors 24, 26 conductive so that a relay 27 is energized and the switch 11 is therefore closed. At the pre-set temperature, the transistor 23 switches off the transistors 24, 26 to open the switch 11 and deenergize the element 10. The switch 11 may be a solid state device.

Filed: 1965-10-28
Abstract: 1,122,832. Winding fabric webs. HALLESCHE KLEIDERWERKE VEB. 28 Oct., 1965, No. 45669/65. Heading B6B. Apparatus for winding together common lengths of fabric cut off from a bale 9 on a measuring table 1 includes an inclined conveyer 4 arranged by the table 1 and comprising a circulating conveyer belt 12 and a winding arrangement 5 having a plurality of winding stations 8 which are equipped with rollers 22, 23 between which are situated roll formers 38 with lead webs 39 secured thereto, the rollers 22, 23 being driven from the belt 12 and each lead web 39 either comprising the end of a previous fabric length or a separate length connected to the roll former 38. The table 1 has a length measuring arrangement 2 and a cutting device 3. The arrangement 5 comprises two parts in star-form between which are mounted the stations 8 each constructed so that the centre of gravity thereof is always situated vertically beneath the pivot point of the bearing 7 thereof. The bale 9 rests between rollers 10, 11 which are motordriven. The belt 12 passes around rollers 13, 14 and a tensioning roller 15 and is driven by the roller 11. After passing the arrangement 2, the individual lengths are marked by an operator and when the marking reaches the device 3 the belt 12 is stopped, the device 3 is operated and then the belt 12 is restarted by means of control knobs 16, 17, 18. The cut length is fed over the conveyer 4 to one of the stations 8 and interrupts a light beam in a photo-cell and light source arrangement 19 to cause a magnet 21 to form a drive connection between gears 32, 34, Fig. 3 (not shown). The gear 32 is driven from the roller 14. A gear 28 is driven from the gear 34 and drives gears 26, 27 mounted on the shafts 24, 25 of the rollers 22, 23, respectively. The cut length is brought into engagement with the lead web 39 on the former 38 by a runway 41 pivoted on a spindle 40 and provided with a wedge-shaped guide 42, Figs. 2 and 3 (both not shown). As the trailing end of the length passes a photo-cell and light source arrangement 44, the runway 41 is moved towards the conveyer 4 by a magnet 46 which attracts a lever 47 rigidly mounted on the spindle 40. Thus, the trailing end is removed from the guide 42 and formed into a new lead web 39, Fig. 2 (not shown). A counter-weight 43 pivots the runway 41 to its initial position. The movement of the arrangement 5 to position the required winding station 8 adjacent the conveyer 4 takes place after the operation of a preselection control knob arranged beside the knobs 16, 17, 18.

In a double wishbone vehicle suspension permitting longitudinal flexibility of a wheel relative to a vehicle frame one of the pivots 3 of a wheel carrier 1 acts as a fixed point while the other pivot 2 is adapted to move longitudinally of the frame in a horizontal plane by being mounted at one end 5 of a lever 6 having its opposite end pivoted to a vertical pivot pin 7 rigid with the corresponding wishbone link 4. Pivoting of the lever 6 is resisted resiliently by buffers 10 which are mounted in the lever and engage the walls 11 of the link 4. In modifications (Figs. 4 to 7, not shown) a horizontal pin (16) passes through the buffers 10, which are hollow, a further resilient member (15) being disposed between the lever 6 and pin (16) to control pivoting of the lever about a horizontal axis through the pin 7. The position of the ball joint 26 between the wheel carrier 1 and a steering rod 25 is chosen to give a small vertical component of movement as the carrier 1 and pivot 2 move longitudinally of the vehicle frame (Figs. 11, 12, not shown).
