Title: Improvements relating to t.r. cells
Inventor: BALDOCK GEORGE SEYMOUR
IPC: H01J17/04
Filed: 1953-01-30
Abstract: 748,885. High-frequency discharge apparatus. FERRANTI, Ltd. April 29, 1954 [Jan. 30, 1953], No. 2677/53. Class 39 (1). A keep-alive electrode in a TR cell in the form of a length of rectangular waveguide is supported by two opposite walls of the cell to provide a rigid structure. In one embodiment, Figs. 1 and 2, the TR cell comprises a short length of rectangular waveguide 10 sealed off at each end by a glazed slot (not shown) and fitted with ionizable gas at low pressure. Two rectangular sheet metal members 16 and 17 extending from the walls 13 and 14 form a resonant slot in which are positioned two triangular electrodes 21 and 22 separated by a small discharge gap 27. The keep-alive electrode includes a wire 23 surrounded by a ceramic sleeve 24 which together pass through the wall 13 and are surrounded by a cup-like bush 25 provided with a glass seal 26, the exposed portion of the wire 23 serving for connection to a D.C. priming source. The discharge portion of the electrode is bent into a U-shaped loop 30 and is further supported by a wire 31 extending part way towards the wall 14 and surrounded by a ceramic sleeve 32 which fits in a socket 33 in the wall 14. In a modified arrangement the discharge portion of the keep-alive electrode is bent into a complete turn surrounding the gap 27. The conductor forming the loop may be a thinnedout integral portion of the conductors 23 and 31, or in cases where distortion produced by expansion and contraction of the conductors is unimportant may be a ring surrounding the gap 27 and brazed or otherwise secured to the conductors. In a further arrangement the discharge portion is a metal bead welded to the conductors 23 and 31 which in this case are parts of a single straight conductor. The space occupied by the keep-alive electrode may be reduced to a minimum in any of the above embodiments by replacing the ceramic sleeves 24 and 32 by a much thinner coating of insulation. The necessary rigidity is then obtained by extending the conductor 31 and its insulating coating through the wall 14 and providing a second bush and seal identical in form with the bush 25 and seal 26. In the embodiment shown in Fig. 6 the discharge portion is made as a U-shaped loop the limbs of which are embedded in a glass bead 39 and the curved part 40 then filed off, thus providing two keep-alive electrodes which may be energized in parallel.

Title: Improvements in snap action electrical switches
IPC: H01H21/42
Filed: 1942-03-06
Abstract: 554,207. Snap-action switches. FOSTER TRANSFORMERS & SWITCHGEAR. Ltd., and MORRIS, F. March 6,1942, No. 2926. [Class 38 (v)] A switch is provided with separately pivoted contact arm 9 and handle-lever 7, connected by a dead-centre compression spring s, the handle-lever carrying laterally projecting pins 1, 2, 3, 4, which; by bearing on appropriate parts of the contact arm and spring link 5, ensure positive starting and finishing to the switching operation. Thus, on opening the switch the handle-lever is rotated clockwise and pin 4 bears on the spring link 5 and subsequently on the contact arm 9 to lift the arm almost to opening position, the actual opening being effected by the spring passing over dead-centre. If the spring has broken, pin 3, by bearing on the surface 10 of the tail of the arm, ensures rapid opening, and in any case, in the open position, the engaging of pin 3 in hollow 11 locks the arm. On rotating the handle-lever 7 anticlockwise, pin 2 tilts over the spring link 5, so that when ;pin 1 positively starts the closing movement of arm 9 the spring is more nearly at dead-centre position, to effect a snap closure, assisted if necessary by the re-engagement of pin 1 with the arm. Specification 530,586 is referred to.

Title: Refractory moulds for investment casting
Inventor: ASTON JACK
IPC: B22C1/16
Filed: 1954-02-02
Abstract: A lost wax moulding process comprises coating a wax or other expendable pattern with a finely divided refractory filler suspended in a liquid binder, dusting a relatively coarse refractory onto the coated pattern, then carrying out at least once the sequence of covering the coated pattern with acid hydrolysed methyl or ethyl silicate solution, the solution being prepared by using only HC1 for the acid to promote hydrolysis and not having any refractory material suspended in it, followed by dusting the coated pattern with a relatively coarse refractory. The coating is then allowed to dry and the mould body formed by investment with a powdered refractory which may be suspended in a suitable bonding liquid.  The initial coating may be 200 mesh silica flint or zirconium silicate in a binder prepared from sodium silicate or potassium silicate, with or without hydrochloric acid, together with a wetting agent such as a soap solution and if desired a film forming agent such as ammonium or sodium alginate or alginic acid.  Other compositions may be bound with ethyl silicate.  One specific example quoted comprises 200 mesh alumina cement, a solution of dioctyl or dinonyl sodium sulphosuccinate, water and 2 ethyl hexanol.  The relatively coarse refractory may be fireclay grog, calcined kaolin, or zirconium silicate.  The acid hydrolysed solution is preferably ethyl silicate, and specific examples of solutions and methods of preparation are quoted.  The body of the mould may be of fireclay p  grog, sillimanite, mullite, calcined kaolin, zirconium silicate, zirconia, silica, or alumina, and binders therefore may be hydrolysed ethyl silicate solutions, or the acid reaction products obtained from the reaction of sodium silicate solution with a dilute mineral acid such as nitric acid.  Alternatively, the body of the mould may be a mixture of alumina and Portland cement bound with water. Specifications 290,717 [Class 22], 650,532, 674,137 and 678,035 are referred to.

Title: Improvements relating to Regulating Circuits
Inventor: COLWILL JOHN ARSCOTT
IPC: H02M3/10
Filed: 1967-01-20
Abstract: 1,179,761. Control of D.C. motors. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 18 Dec., 1967 [20 Jan., 1967], No. 3210/67. Heading H2J. [Also in Division G3] In a regulating circuit of the type which switches between two states to maintain a first quantity, e.g. voltage, at a value set by a first reference signal, this first reference signal is arranged to be modified when a second quantity, e.g. current, reaches a predetermined relationship with a second reference signal, whereby control in dependence upon the second quantity supersedes control in dependence upon the first quantity. As shown, a load 10, e.g. the traction motor of an electrically-driven vehicle, is supplied from a D.C. source 10 by way of a chopper regulator 8 and a current sensor 2. A sawtooth waveform from a source 1 is compared in a comparator 3 with an adjustable D.C. reference voltage from a source 4 which may be associated with the foot-pedal of the vehicle and the output from the comparator, applied to the regulator 8 over a pulse generator 7, determines the voltage applied to the load; if the load current exceeds a predetermined value, a second comparator 5 associated with a second reference source 6 produces an output which is applied to the source 4 to modify the reference voltage supplied thereby. Thus current control overrides voltage control when an excess current flows in the load.

The ribs 2 in the posts are formed between horizontal apertures 3 which communicate with vertical apertures 9 in which the projections on the blocks are eventually housed. The vertical edges 7 of the blocks may overlap the posts to cover them completely or partially and the space between the overlapping parts of the blocks and the posts may be filled with a bonding or sealing material applied with a cement gun. The outside faces of the blocks may overlap to produce a weather-boarding effect. A similar arrangement may be applied to roofs as shown in Fig. 6.
