Title: Improvements in or relating to television
IPC: H01J31/26
Filed: 1934-02-22
Abstract: 413,996. Television transmitters. HENROTEAU, F. C. P., 150, Elgin Street, Ottawa, Canada. Feb. 22, 1934, No. 5877. [Classes 39 (i) and 40 (iii).] An optical image is impressed on a photosensitive surface 8, the electrons emitted are collected to form an electrostatic reproduction on a grid 12, and an electronic stream is then caused from each point of the surface 8 in sequence and is picked up at an anode 6, modulated by the electrostatic reproduction. The transmission is divided into the three following stages:-(1) The cathode 7 and the anode 6 are connected to comparatively high negative potentials 37, 23 by commutators 30, 16 so that the grid 12 which consists of discrete zinc particles on quartz fibres, is relatively positive. An image of a view is simultaneously projected on the cathode through a lens 4 in the opaque wall 2 of the cell 1 co-operating with an opening 14 in a revolving shutter 13. Each part of the photosensitive coating 8 emits electrons depending on the intensity of the incident light. These electrons are collected by the nearest insulated metallic elements on the grid, which thus has an electrostatic reproduction of the view. (2) The view is interrupted by the shutter 13, the cathode connected to earth 39, and the anode connected to comparatively high positive potential 26 and to the grid 28 of the first valve 29 of a transmitter. A very strong beam of light from a cathode-ray oscillograph 40 scans the sensitive surface of the cathode through the opening 14 and a lens 5. The electrons emitted by the action of this beam are attracted to the anode by its positive potential, but their number is modulated by the potential of the particular element of the grid near which they pass. A similarly modulated potential is thus impressed on the valve 29. (3) The scanning beam is interrupted by the shutter 13, the cathode and anode are connected to earth 36, 22 and a strong beam of ultra-violet light 43, 44 is projected on the grid through the aperture 14 and a quartz window 3. The zinc elements on the grid, which are sensitive to ultraviolet light, emit electrons until all the elements reach a uniform zero potential. According to modifications : a negative of the grid is illuminated by the ultra-violet light and projected on the grid so that no light passes to the cathode, Fig. 4 (not shown) ; three similar apparatus are used and the transmission is continuous ; strong images are obtained of faint objects such as views in telescopes or microscopes; the cathode is of thin aluminium or beryllium and is scanned by making it the screen of a cathode-ray oscillograph; the shutter and commutators are on different shafts. Specifications 335,958 and 335,995, [both in Class 39 (i)], are referred to.

Filed: 1962-02-15
Abstract: 949,129. Injection moulding machines. DOWDING & DOLL Ltd. Dec. 19, 1962 [Feb. 15, 1962], No. 5950/62. Heading B5A. In an injection moulding machine having an axially reciprocable screw 1, a piston head 10 of smaller diameter than the root of the screw is rigidly fixed to the end of the screw and is adapted to enter a cylinder 12 in which it is a close sliding fit as the screw approaches the limit of its forward travel. The pressure applied to the injected material is thus increased and can be maintained for a longer period. The cylinder 12 and nozzle 5 are formed in a replaceable hardened insert 15. Specification 909,449 is referred to.

Title: Improvements in machines for manufacturing tiles and like articles
IPC: B28B11/14
Filed: 1950-03-09
Abstract: 688,548. Machines for moulding tiles &c. on pallets. O'SULLIVAN, E. June 11, 1951 [March 9, 1950], No. 6000/50. Class 87 (ii). Feed elements 26 on pivotally mounted members 25 carried by a continuously moving endless chain 12 remove the lowermost pallet 10 from a hopper 37 and push it along between guide rails 9. The elements 26 are withdrawn from the pallets, when the members 25 reach a guide 29, so that the pallets are then pushed intermittently through the machine by the pressure of the following pallets. The pallets pass beneath a concrete supply hopper 38, Fig. 6, having an agitator 40, an exit roller 42 for determining the thickness of the concrete layer and a smoothing block 44. The guide rails beneath the roller and block are curved and the upper surfaces of the pallets are curved to form curved tiles. Powdered cement, which may be coloured, is then sprinkled on the concrete from a pivoted hopper 56 which is shaken by cams 58. The layer of concrete is cut longitudinally by a spring-urged rotary knife 62. As each pallet reaches the transverse cutting and punching position it is held by stops 96. Each stop is slidably mounted in a holder 97, Fig. 2, pivoted to a fixed bracket 100, to allow the stops to move if the machine is set up wrongly or a pallet of incorrect size is used. The holders are held in position by a spring 103 fixed at one end to the frame of the machine. During normal working, a shaft 95 is continuallv rotated and clutch members 118, 119 engage to rotate cams 113 on a collar 114. The cams raise the stops 96 against springs 111 to hold a pallet in position. When the knife and punches have made their stroke, the cams allow the stops to fall and the pallets to move on. If the machine is driven in the reverse direction, e.g. when clearing a stoppage, the clutch members force the collar 114 axially against a spring 120 so that the bottoms of the stops are moved off the cams onto cylindrical parts 122, thus allowing the stops to remain out of action. The punch 77 and knife 65 are each mounted on a slide 66 which is reciprocated by a cam 84 and springs 68. Both the punches and the knife are spring- mounted on the slide to prevent damage if they engage hard .material. Specification 414,896 is referred to.

Filed: 1934-02-24
Abstract: 412,151. Mixing &c. machines. STYLES, W. ELLERD-, 9, Pentonville Road, London. Feb. 24, 1934, No. 6134. [Class 86.] In a dough mixing and kneading machine of the kind in which the arms are given intersecting elliptical paths in a rotating bowl, means are provided whereby the raising and lowering of the mixing and kneading arms respectively can only be effected in a certain sequence. The arms are provided with racks operated by a removable pinion which can only be transferred from one arm to the other when the first has been moved to its proper position. The kneading-arm 21, Fig. 8, having the rack 28, slides in a sleeve 23 and is raised and lowered by means of a pinion 36 formed on a spindle 35 having a flange 48, the arm having a cut-away part 32 to allow the insertion of the spindle into operative position. In this position the end 37 of the spindle forces a locking pin 43 out of engagement with a recess 46 in the arm. Rotation of the spindle 35 then raises the arm, the collar 48 riding in a channel in the arm and preventing the removal of the spindle till the arm has been lowered ; the arm is retained in its raised position by a spring detent. The mixing-arm is operated similarly, the recess 32 being in such a position as to allow the withdrawal of the spindle when the arm is raised. The locking-pin 43 may be replaced by a hardened steel ball engaging a recess in the arm and freed therefrom by the movement of a spring bolt engaged by the end of the spindle.

Title: Improvements in and relating to dimethyl silicone elastomers
Filed: 1945-03-13
Abstract: A dimethyl silicone is mixed with ferric chloride, or with ferric oxide and aluminium chloride, or with chlorinated tricresyl phosphate, or with a mixture of chlorinated tricresyl phosphate and ferric oxide or ferric chloride until a gum is formed, and the gum is milled until it attains a consistency suitable for moulding or extruding.  The dimethyl silicone is prepared from a dimethyldichlorosilane fraction containing not more than 2 mols. per cent of methyltrichlorosilane.  It preferably has a methyl to silicon ratio of 1.98-2.00.  The chlorinated tricresyl phosphate has a composition corresponding closely to the monochlor derivative, the chlorine being in the side chains.  The products are useful for gaskets, for electrical insulation or as shock-absorbers.  Examples describe: (1) hydrolysis of dimethyl silicon dichloride with aqueous hydrochloric acid.  The oily layer was separated, washed, dried and freed by distillation from low-boiling substances.  The residue was mixed with ferric oxide and a little aluminium chloride, the mixture worked on rolls at 125 DEG  C. and moulded to sheet form at 150 DEG C.  The sheet was further cured at 200 DEG  C.  Low-boiling dimethyl silicones alone or mixed with higher boiling ones may be treated with small amounts of iron chloride before being treated as above and this embodiment is illustrated in example (2), the gum formed by treatment with ferric chloride being dissolved in toluene, filtered and recovered by evaporation before treatment.  Example (3) describes a treatment of dimethyl silicone with ferric oxide and a little tri-(mono-chloro-paracresyl) phosphate at 150-180 DEG  C. followed by milling at 125 DEG  C.  Additional chlorinated tricresyl phosphate was incorporated while milling.  The product was moulded at 150 DEG C. and further cured in an oven at higher temperature.  Example (4) describes treatment of a dimethyl silicone with ferric chloride, followed by working with carbon black and chlorinated tricresyl phosphate.  Example (5) mixes dimethyl silicone with titanium dioxide, ferric oxide and a little aluminium chloride followed by mixing on heated rolls with addition of further aluminium chloride. The material was extruded and finally cured at 200 DEG  C.  Other fillers which may be used are whiting, lithopone, talc or zinc oxide.

Title: Electrical signal transmission systems utilising angular modulation
IPC: H04B14/00
Filed: 1967-02-09
Abstract: 1,104,030. Frequency modulation; companders. NIPPON ELECTRIC CO. Ltd. 9 Feb., 1967 [4 March, 1966], No. 6330/67. Headings H3R and H4R. In a companding system for improving the signal to noise ratio of a frequency modulation system, the output of a frequency-modulated oscillator 13 at the transmitter is fed through an amplitude limiter 16 to an amplitude modulator 171 feeding a discriminator 172 which responds to the amplitude and frequency of its input and provides negative feedback to the subtracter circuit 12 supplied with an input signal at terminal 11 and controlling the frequency of oscillator 13. The output of discriminator 172 also passes to a level detector 173 the output of which is combined in unit 175 with an input bias signal supplied to terminal 174, the combined signal being fed to. modulator 171 to amplitude modulate the feedback signal. It is shown that this circuit produces a hyperbolic expansion determined by the gain of the detector 173 and by the bias at input terminal 174. The local demodulator 17 may be used as the demodulator on the receiver side. A modified demodulator unit 17, Fig. 3 (not shown), employs three amplitude modulators 171 with three bias inputs, thereby providing a more complicated expansion characteristic.
