Abstract: 1,237,849. Electron microscopes. COMPAGNIE GENERALE D'AUTOMATISME. 16 April, 1970 [16 April, 1969], No. 18177/70. Heading H1D. An arrangement for providing access to part of a high voltage electrical apparatus such as an electron microscope 4 arranged within an electrostatic screen 32 within a casing 2 preferably filled with sulphur hexafluoride, comprises a tubular lock which can be moved from a disengaged position shown at 12 ,to an engaged position -shown at 10. In the latter position the lower end is sealed at 14 and the upper end is provided with a gas-tight joint 16 so that the sulphur hexafluoride within the tubular housing 20 may be pumped out and replaced by air after which the inner part of the housing may be removed; a canister 6 containing accumulators for heating the cathode of the microscope may then be removed by means of a rod (not shown) which may be screwed into a tubular bush at the top of the canister and this allows access to the electron gun (not shown) so that the filament may be changed. The accumulators may be re-charged without removing the canister by means of leads attached to a rod 46 which is located within a guide tube 44 and which may be driven downwards by means of a motor (not shown) in a housing 66 so that the leads engage complementary connections on the canister; these connections also allow the canister to be earthed before the lock 10 is operated. The gap in the electrostatic shield 32 necessary to allow passage of the lock is partly closed by a screen 36 attached to the canister 6, and a similar screen 40 closes the lower end of the housing 20.

Patent GB-875309-A (GB)
Title: Improvements relating to electrical gear-change devices for change-speed gearings, especially for motor vehicles
Filed: 1959-05-28
Abstract: 875,309. Change-speed control. DAIMLERBENZ A.G. May 28, 1959 [May 29, 1958], No. 18210/59. Class 80 (2). The forks 11 of a vehicle change-speed gear are operated by cam slots 12 in a rotary disc 10 driven by a reversible .electric motor 13 through a slipping clutch 14 and worm gearing 15, the disc being locked in a particular gearchange position by the engagement of a solenoid-operated pawl 17 in the appropriate one of a series of notches 16 on the periphery of the disc. Control is effected by push-button switches S 1 , S 2'  S 3 , S 4  for up-change, downchange, neutral and reverse, respectively. Upon momentarily depressing switch S 1 , for example, a circuit is completed through a relay R 3 , release switch S 6  solenoid 18 of pawl 17, locking switch 23 of relay R 2  and excitation winding 20 of relay R 1 , whereby pawl 17 is lifted and motor 13 turns disc 10 through an angle appropriate to a single up-change, the circuit then being opened by a cam 32 on disc 10 opening switch S 6  to de-energize solenoid 18 and allow pawl 17 to engage the next notch 16. During each gear change a switch S 11  is operated to disengage the vehicle clutch. By holding switch S 1  depressed a change through a plurality of gears may be achieved. The circuits through relays R 1 , R 2 , R 3 , R 4  are reversed by operating switch S 2  for changing down. Neutral switch S 3  acts upon both control circuits through lines 44, 45 and locking switches S 7'  S 8  operated by a separate cam 46 on disc 10, and the arrangement is such that if a forward speed is engaged the control circuit for downward change is closed, and conversely. Reverse switch S 4  is connected through lines 48, 50 to line 37 for downward gear change. An engine-driven governor operates three switches K 1 , K 2 , K 3 , the first of which is closed automatically above a predetermined speed to close the automatic circuit for up-change, the second when the speed falls below a second predetermined value to close the down-change circuit, while the third operates to cut-off the circuit for down-change when the governor speed falls below the maximum engine speed by the difference between the gear stages, thus preventing a change down. In a second arrangement, Fig. 2 (not shown), all the relays are arranged in parallel circuits so that mutual influencing is avoided.

Patent GB-1563537-A (GB)
Title: Method and apparatus liquids
IPC: B01D35/22
Filed: 1977-05-02
Abstract: The process and the apparatus serve for removing impurities, particularly heavy metal ions, from aqueous liquids in which these impurities are contained. The impurity-containing liquid is brought into contact with a particle-forming treatment material, which effects the removal of the impurities from the liquid stream by reaction by ion exchange or by adsorption. The liquid is passed through an inert packed layer of a particulate finely divided filter material which is retained in perforations in the vessel wall directly adjacent to the treatment material. The filter material has a particle size such that the penetration of any particulate solids contained in the liquid is prevented. Furthermore, the inner surface of the vessel wall, to avoid a blockage of the particulate material, is scraped off over the perforations in which the filter material is retained.

One flute 23 interrupts a plurality of both shank and end threads and extends to the point. The other flutes 26 each interrupt a plurality of shank threads and at least one end thread, and terminates short of the point. The flutes end on the shank substantially at the root between adjacent threads.
Patent GB-486362-A (GB)
Title: Improvements in and relating to devices for dividing artificial filaments issuing from spinning nozzles
IPC: D01D5/26
Filed: 1937-07-02
Abstract: <PICT:0486362/IV/1> <PICT:0486362/IV/2> <PICT:0486362/IV/3> <PICT:0486362/IV/4> Apparatus for producing artificial fibres comprises spraying or blast nozzles situated outside the path of artificial filaments issuing from spinning nozzles and arranged to discharge jets of liquid or gas at right-angles or obliquely to the direction of travel of the filaments, and means for causing the jets to contact with the filaments intermittently so as to break them into substantially uniform lengths.  The spraying. nozzles may be stationary and may be operated intermittently, or they may be moved to and fro and operated so that the fluid jets issue in continuous uniform currents which during their motion divide the filaments.  As shown in Fig. 1, artificial filaments 5 from spinning nozzles 1 are divided into fibres by a jet of gas, air, or liquid 4 issuing from nozzles 3.  Preferably a separate nozzle 3 is provided for each filament 5.  The nozzles 3 are supplied from a tubular body 2.  When a liquid is used, the jet may be prevented from acting on the filament like a knife-edge, by reducing the velocity or the angle at which the jet crosses the filament.  When air or gas is used the tube 2 may be connected with a small pump similar to those used in hair-driers.  An air-liquid jet obtained by means of an atomizer may be used.  The nozzles 3 may move to and fro, or they may be stationary.  In the latter case, the supply of fluid to the pumps or the delivery to the nozzles is intermittent.  The spinning orifices may be arranged in a row.  As shown in Figs. 5, 6, the nozzle body for the spinning mass or for the spraying medium comprises two members 11, 12, each having a trough-like depression 13, 14 extending parallel to the front edge.  The front edge of the trough 13 has narrow notches 15 while the edge 16 of member 12 is smooth.  The two members 11, 12 are assembled together by bolts.  The notches 15 then form the orifices of the nozzles.  The construction may be varied by providing the trough-like depression in one of the members 11, 12 only.  Twist to the outgoing streams of fluid may be imparted by constructing the nozzle openings in the form of a quick-pitch screw thread.  Fluid may be supplied to the nozzle by a plurality of supply pipings from a pump.  As shown in Fig. 8, the nozzle body 21 is conical and is inserted in an annular body 22.  An annular groove 23 communicates with a supply pipe 24 by bores 25.  Spinning solution passes from pipe 24 to groove 23 and is extruded through the axially directed grooves 26.  Air or liquid passes from pipe 33 into the space 31 and is forced intermittently outwards over the edge 29 of disc 27, so that the filaments issuing from grooves 26 are divided and the separated fibres are conducted away from the nozzle.  The spraying nozzles may be supplied with precipitating liquid.  The spinning nozzles may dip into a precipitant or be arranged at a short distance from it.
