Title: Apparatus for moving vehicle lamps
IPC: B60Q1/05
Filed: 1971-11-25
Abstract: 1444361 Controlling vehicle lamps LUCAS ELECTRICAL Ltd 13 Nov 1973 [28 Nov 1972] 54822/72 Heading F4R Apparatus for moving a vehicle head-lamp between an operative position and a retracted position within the vehicle body comprises a fluid pressure actuator having a movable element which is connected to the lamp and is movable between a rest position corresponding to the retracted position of the lamp and an operative position corresponding to the operative pcsition of the lamp. The element is biased by a spring or counterweight towards one of its positions and the application of fluid pressure to the actuator to move the element to its other position is controlled by either of two valves, each of which is biased towards a rest position and, when operated, causes movement of the element to its operative position. The valves are operated mechanically by respective switches which control the illumination of the lamp, the first switch being a conventional on-off switch having stable on and off positions and the second switch being a lamp-flashing switch having a stable off position and an unstable on position in which it must be held against spring pressure. The second valve is associated with timedelay means which delay the return of the valve to its rest position for a predetermined time during which the lamp can be flashed several times. The fluid pressure is preferably the vacuum produced in the inlet manifold of the vehicle engine but may if desired be obtained from compressed air.

Abstract: 1,222,767. Filling moulds. W. SCHNEIDER, and K. SCHNEIDER. 13 Nov., 1969 [21 Nov., 1968; 22 May, 1969; 7 June, 1969], No. 55517/69. Heading B5A. Concrete elements are formed in a mould 10 divided into a plurality of separate compartments which fit flush into an opening in a table top 12 from a predetermined quantity of concrete mix. To fill the mould, concrete is swept across the open top of the mould on to the table beyond the mould, while at the same time the mix is displaced sideways at right angles to the direction of sweep and the remainder of the mix is then swept back with simultaneous reversal of the horizontal sideways displacement. The table 12 carries two rails 14 on which the filling box 30 runs. Concrete is supplied from hopper 24 to the filling box 30 and some passes through a grid of metal strips 40, 41. As the filling box moves across the moulds, deflecting plates 42, 44 and metal tabs 43, 45 force some of the concrete sideways to fill the moulds evenly, the deflecting tabs and angles acting to deflect the concrete sideways in the the opposite direction as the box returns to its starting position. The mould supporting table 16 may be vibrated by vibrators 18, and the filling box may be subjected to small amplitude oscillations along the direction of rails 14 when it is over the mould and nearer to the side remote from the feed hopper. The concrete may be compacted by rams 20 equipped with vibrators and the ends of the rams may comprise plates 120 with a central tapered hole formed by downward extensions 150, through which excess concrete is forced.

Filed: 1973-12-04
Abstract: 1450908 Soldering MISHIMA KOSAN CO Ltd 4 Dec 1973 [4 Dec 1972] 56216/73 Heading B3R Apparatus for soldering electrical connections of electric circuit elements comprises a laser source 2, a first mirror 23 for reflecting a laser beam from the laser source to the connection to be soldered a light source 22 for illuminating the connection to be soldered, translating means for effecting relative movement between the circuit elements to be soldered and the first mirror, for moving the spot at which the laser beam is directed, and a second mirror 20 having a hole 21 therethrough for the passage of the laser beam, the arrangement being such that a light ray from the source 22 is reflected by the second mirror to be concentric with the beam and is reflected with the beam by the first mirror on to the connection to be soldered. In an embodiment the source 2 is a gas laser tube 3 with concave mirrors 4, 5 at its ends, the mirror 5 having an opening 5A, a water cooling jacket 6 and discharge electrodes 7, 8. Carbon dioxide or a mixture of carbon dioxide and nitrogen or helium is fed to the tube 3 from a source 10 via a flow rate regulator 11, a vacuum pump 12 being provided to exhaust the tube prior to the supply of gas from source 10. An electric power source 14 is connected to the electrodes 7, 8 through an on-off timer switch 15 and a voltage regulator 16. The mirror 20 as a disc is disposed so that its central aperture 21 allows the laser beam to pass to the mirror 23, a lamp 22 being arranged to cause a light ray to be reflected from the mirror 20 on to the mirror 23 to assist the operator to locate the laser beam. The mirror 23 reflects the light ray and the laser beam through a lens 32 on to the elements to be soldered carried on a carriage 30. The mirror 23 is mounted on a rack, driven by a pinion rotated by a motor 17 controlled by the switch 15, to move along the line of the beam and the carriage is mounted for movement in two directions at right angles to locate the elements to be soldered. The carriage may be moved, while the mirror 23 is stationary, by a motor driving a rack and pinion mechanism. In use the laser may be operated continuously or intermittently while the elements to be soldered are moved continuously beneath the mirror 23 or the mirror is moved continuously over the elements. The laser may be operated intermittently, the laser being off while the mirror 23 or carriage is moving and on when the mirror or carriage is stationary or the laser may be on only while an element is moving relatively to the beam. In modifications the mirror and carriage may be moved by lead screws or wires and a He-Ne laser, Ar laser, solid laser or semi-conductor laser may be used. The connections to be soldered may be carried on a metal, glass or resin base plate and to protect the base plate it may be masked.

Abstract: 1,158,408. Knitting-machines. WIRKMASCHINEN-FABRIK WILHELM BARFUSS G.m.b.H. 20 Dec., 1966 [23 Dec., 1965], No. 56885/66. Heading D1C. In a warp knitting machine the shogging of each guide bar is controlled by a series of cam follower levers 9 selectively brought into engagement with tracks of a main pattern chain 6, by means of an auxiliary chain 34. For controlling one guide bar, each of several levers 9, having follower rollers 8, are connected to one common ram 17 connected to the guide bar, and pivoted to an individual second lever 11. The lower end of lever 11 of an operative lever 9 is forced against a fixed stop 14 by a cam on auxiliary multitrack chain 34 via lever system 13, 37, 36. Lever 11 therefore provides a fixed pivot for the follower lever 9 which controls the shogging movement by means of main chain 6. Inoperative levers 9 are maintained clear of the pattern chain by their auxiliary lever systems which engage low cams on chain 34, when a new track is to be read the end of the corresponding lever 11 is urged towards stop 14 by the auxiliary lever system and the previously operative follower lever disengaged. Stops on the auxiliary chain bring the next lever 11 gradually towards the stop 14 over several courses, depending on the relative height of the two tracks.

Title: Improvements relating to hydroconversion of hydrocarbons
IPC: C10G47/00
Filed: 1966-12-20
Abstract: A process for improving the activity and reducing the ageing rate of a catalyst which has become partially deactivated in a process for the hydrocracking of a hydrocarbon charge stock comprises bringing the catalyst into contact under hydrocracking conditions with a hydrocarbon charge stock of reduced polycyclic aromatic content (e.g. containing less than 11% by wt.) as compared with the original charge stock.  Suitable hydrocracking catalysts comprise a hydrogenating component such as a Group VIII metal or metal compound, e.g. Ni alone or in conjunction with compounds of molybdenum or tungsten, supported on a cracking component such as Al2O3, MgO, SiO2, or mixtures thereof or a zeolitic alumino-silicate having pore openings of 6-14 <\>rA. Suitable hydrocracking conditions include a temperature of 450-775 DEG  F., a pressure of 500-10,000 p.s.i.g. a hydrogen rate of 1000-20,000 SCFB, and a space velocity of liquid charge of 0.1 to 10 vols per vol. of catalyst per hour. When the hydrocarbon charge stock contains more than 20 p.p.m. nitrogen it should be first subjected to a catalytic denitrogenation.  If the hydrocracking catalyst is not sensitive to ammonia, the entire effluent from the denitrogenation zone may be sent directly to the hydrocracking zone, but if not, the hydrogen may be subjected to a basic nitrogen removal treatment, e.g. by washing with dilute acid and stripping with an inert gas before being fed to the hydrocracking zone.

IPC: H01S3/0971
Filed: 1970-12-04
Abstract: 1301207 Lasers NATIONAL RESEARCH DEVELOPMENT CORP 17 Nov 1971 [4 Dec 1970] 57848/70 Heading H1C An electrode system particularly suited to atmosphere pressure pulsed CO 2  lasers comprises a pair of elongated main electrodes 10, 11, Fig. 1, and one or more auxiliary or trigger electrodes 12 offset to one side or the other of a plane containing the centrelines of the two electrodes. This offset, and the electrical components used, are shown in Fig. 3. The main electrodes have a curved Rogowski profile though this is not essential, and in Figs. 1 and 3 the trigger electrodes are tungsten wires. Capacitor 15 is charged by high voltage source 19, and when spark gap 16 is triggered the voltage on the capacitor appears across the main electrodes 10 and 11. Because of the field concentration around the wire electrodes 12 a discharge initially occurs between them and the anode 11, and this triggers a homogenous discharge between electrodes 10 and 11. The capacitors 14 allow the wire electrodes to assume a potential which does not perturb the main discharge pulse. The pulse duration must be no more than a few hundred nanoseconds if bright arcs are to be avoided. The trigger electrodes may be replaced by pins, each of which may be resistively loaded, Figs. 5, 6 (not shown), or by a sharp edged plate, Fig. 4 (not shown). Alternatively the trigger discharge may occur between a pair of separate trigger electrodes as in Fig. 8a where pins and studs 12 are used. These separate electrodes may alternatively comprise a sharp edged plate and a Rogowski profiled bar, Fig. 7a (not shown). For low pressure inert gas lasers the trigger cathodes may be heated. The mechanism by which the main discharge is initiated from the trigger discharge is thought to involve photo-electrons produced by ultraviolet radiation from the trigger discharge.
