March 30, 1962 [April 1, 1961; Aug. 26, 1961; Nov. 14, 1961], No. 12336/62. Heading E2M. [Also in Division F2] A drive device for the operation of a sliding window in a motor vehicle comprises a driving shaft 12 having a recess 40 formed in the periphery thereof, a toothed annular element 11 punched from sheet metal and substantially coaxial with the shaft, a driving element 32 extending in an axial direction of the shaft and in the recess 40 and fast with the element 11 for driving it when driven by the shaft 12, a coil spring 26 encircling the shaft for frictionally engaging a braking surface on the cupped part 14 and end portions 25, 27 of the coil spring bent over inwardly and which are adapted to abut shoulders on the periphery of the shaft. As shown notches 36, 38 in the toothed wheel 11 engage the ends of limbs 30, 34 of the driving element 32 which are accommodated in the recesses 40, 42 of the shaft head part 42. The latter is fitted on serrations 22 of the shaft 12 which is also formed with serrations 20 on which is mounted a crank handle 21, Fig. 1 (not shown). The shaft may alternatively be driven by an electric motor. The toothed wheel 11 which may have spur-form or helical teeth engages the helical rib 6<SP>1</SP> of a cable housed in a tubular guide and connected to the window. The spring 26 is housed in a recess 44 in the shaft head 42 and frictionally engages the cupped part 14 which is screwed or riveted to a part 16. The arrangement is such that when the shaft 12 is rotated one of the shoulders on the shaft head 42 engages one of the ends of the spring 26 to reduce its diameter thus allowing the toothed wheel 11 to drive the cable to move the window. In another embodiment the shaft head 42 is formed of a plurality of discs which have a serrated central bore and outer peripheral recesses, the discs having their radial faces in contact. The driving element 32 has four limbs, two of which are accommodated in the recesses in the shaft head and the other two engage apertures in the toothed wheel.

Abstract: 795,536. Weighing apparatus. WOOD, J. T. March 26, 1956 [April 29, 1955], No. 12387/55. Class 143 [Also in Group XXXV] In an apparatus for test weighing continuously delivered articles or measured quantities and stabilizing the individual weights of succeeding articles in dependence on the weight test, a weigh-beam causes to be energized one of a pair of electrically interlocked quick acting relays to initiate the correction. As a result of a test weighing weigh-beam contact 11, Fig. 1, makes contact with contact 12 or 13 and energizes through a step down transformer relay 16 or 17 to effect correction through contacts 16a, 16b, 17a, 17b, electrical interlocking being introduced by contacts 16d, 17d. The sampling and the closure and release of main switch 15 is effected by the delivery machinery and correction is effected by one of a pair of solenoids through, for example, a rack and pinion mechanism. Alternatively the solenoids may act indirectly to actuate valves to control the admission of a pressure medium to cylinders of which pistons supply the correcting motive power. Correction by moving the stops to alter the travel of a reciprocating plunger in a gob feeding machine is also described. Limit switches. Fig. 4 (not shown), may be provided to prevent further adjustment when a predetermined cumulative number of adjustments have been made and to give a visual or audible warning. The limit switch which corresponds to persistent underweight may be arranged to initiate a subsidising feed adding to the weight of the articles. 'The weigh-beam 21, Fig. 2, which is mounted on a pivot 22 is electrically conductive and has an insulated cover 23 in which are mounted contact screws 24, 25 the contact clearance being very small. The weight pan 26 acts through a pillar 27 and the goods pan 29, which slides in parallel spaced arms 30, 31 carrying counterweights 32, 33, through pillar 28. The pan is controlled by a piston 40 in a cylinder 41 through pipes 45, 46 and admission to the pipes is controlled in depedence on the delivery of the machine. On withdrawal of the pan, material adhering thereto is removed by a scraper 47. Mechanism for the transfer of articles from the conveyer to a dead plate and from the dead plate to the pan and vice versa comprising a swivel cylinder driving a finger plate and fixed cylinders and pusher bars is also described. Apparatus may also be provided for recording continuously the control settings and corrective resettings of the control apparatus.

Title: Improvements in antenna systems
IPC: H01Q11/06
Filed: 1944-06-30
Abstract: 587,543. Aerials. PRESS WIRELESS, Inc. June 30, 1944, No. 12506. Convention date, June 15, 1943. [Glaas 40 (v)] The terminating impedance of a rhombictype aerial used primarily for transmission is constituted by a similar rhombic-type section mounted beneath the radiating section and connected to it by a transmission, line. As shown in the Figure, the aerial comprises a radiating rhombus 1 of copper wires energized from the transmitter 11 through the transmission line 12 and mounted on poles about 100 ft. above the ground over a dissipating rhombic section 2 to which it is connected by the transmission line 16, 22, corresponding wires of the two sections being in the same vertical plane. Due to its ctose proximity to the ground, the lower section has a high attenuation which may be increased by forming it of stainless steel wire and the near apex 26 may be earthed directly or through a resistance equal to the characteristic impedance Zo of the system. Alternatively, the two legs 18, 24 may be bridged near the apex 26 with a resistance equal to Zo having an adjustable earthing point, Fig. 6 (not shown), or the apex 26 may be connected to a two-wire transmission line of high attenuation which may be terminated, in a further network of spaced wires at a place where the ground-induced resistance is more favourable, Fig. 7 (not shown). The legs of the sections may be given an exponential instead of a linear separation to obtain impedance matching, Fig. 5 (not shown). The planes of the two rhombic sections may be inclined towards each other to modify the directivity of the aerial, Figs. 8 and 9 (not shown). Details of the supports are illustrated in Figs. 2-4 (not shown). The Specification as open to inspection under Sect. 91 describes a single rhombic aerial in which impedance matching is obtained by forming each radiating conductor of two diverging wires, the plane of each pair of wires being at an angle to the vertical. This subjectmatter does not appear in the Specification as accepted.

[Also in Group XIII] A vehicle is heated by air carrying engine heat, e.g. air warmed by the engine coolant, a valve arrangement for regulating the warm air flow incorporating interlinked manual control and automatic control responsive to the pressure or to the temperature and pressure of the warm air. Air is blown by a fan v', through one radiator k' of several in the coolant circuit of an engine m, into a duct l which branches into a duct e venting to outside the vehicle and into a duct h connected to the double-walled floor w of the vehicle. A valve d<SP>2</SP>, in the vent duct e, is opened upon increase of air pressure. It may be pivoted by means of a spiral spring f so as to be directly pressure-operated or it may be responsive to the pressure in the duct I or in the duct h by means of a barometric capsule. The valve d<SP>2</SP> is connected with a valve d' in the duct h by an interlinkage g' operable manually and preferably operable also automatically according to the warm air temperature. The interlinkage is such that, if not opened by the pressure control, the vent valve d' closes as the valve d' opens and vice versa. From the floor w, the air may pass into the open at b<SP>1</SP> or through gratings s into the vehicle near the doors, a linkage g<SP>2</SP> providing changeover control. Some of the air may be used for heating the windscreen or battery. A thermally operated valve t in the coolant circuit controls a bye-pass of a main radiator k<SP>2</SP>. The delivery of the fan v' may be controllable as described in Specification 711,909.

Title: Conversion of hydrocarbons
IPC: C10G11/16
Filed: 1946-04-26
Abstract: <PICT:0620146/III/1> In the catalytic cracking of gasoline, a <PICT:0620146/III/2> heavy hydrocarbon oil, with at least 25 per cent boiling above the temperature in the conversion zone, is contacted with a catalyst circulating in a closed cyclic path through an enclosed conversion zone, where it moves as a substantially compact column of particles, and through a regenerating zone.  An oil having at least 25 per cent boiling above the conversion temperature of about 800 DEG  to 1000 DEG  F. is heated to less than that temperature and introduced into the catalyst in the conversion zone from which the vaporous hydrocarbon products are removed.  The escape of hydrocarbon vapours with the catalyst during its movement from the conversion zone to the regeneration zone is prevented, the catalyst being subjected in the regeneration zone to a high temperature combustion regeneration and then retransferred to the conversion zone while preventing the passage of combustion gases with it. Appropriate means may be provided at any point in the cycle for the removal of spent or fine catalyst and for the introduction of new catalyst and conditions are adjusted to maintain the temperature in the conversion zone at between about 800 DEG  F. and 1000 DEG  F.  As shown in Fig. 1, oil is heated in furnace 8 and introduced through spreader 9 to a catalytic contact mass in particle form moving down reactor 1.  The cracked vapours are removed through collector 10 to a fractionator 12, gaseous products being led off through 13, gasoline through 14 and re-cycle oil stock through 15.  The catalyst is transferred by an elevator 3 to a regenerator 2, purge steam or inert gas being introduced at 17 to prevent escape therewith of hydrocarbon vapours.  Air for regeneration is introduced at 18, 19 and combustion gases removed at 20, 21.  Heat for regeneration is provided by coils 22 and 23 and purge gas introduced at 24 to prevent escape of combustion gases with the catalyst during its transference back to the reactor by elevator 5.  In a modification, Fig. 4, oil with a long boiling range and including fractions boiling both below and above the conversion temperature is heated in a furnace 120 from which the oil/vapour mixture may be directly introduced to the catalyst through pipe 121 and distributor 122 or may be separated in 138 so that the vapours are separately introduced through distributor 140.  The vapours are led off from the top of the reaction chamber through 126 and through collector 123 at the bottom to a fractionator 125.  In further modifications, Figs. 2 and 3, not shown, (1) heated oil and its vapours are introduced in the middle of the catalyst mass and all the vaporous products taken off from the top of the reaction chamber, and (2) heated oil is introduced in the middle of the contact mass, its vapours being introduced at the top of the reaction chamber and all the vaporous products are taken off at the bottom of the reaction chamber.  Specification 558,946 is referred to.
