Title: Process for the manufacture of sound-and-heat-insulating covering sheets or slabs, particularly for flooring
IPC: E04C2/16
Filed: 1935-05-30
Abstract: 451,625. Nonconducting coverings for heat and sound. SCHREIBER, E., Thusis, Graub³nden, Switzerland. May 30, 1935, No. 15808. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 2, 1935.] [Class 64 (ii)] [See also Group X] A sound and heat insulating sheet or slab, particularly for covering floors, is made by impregnating a surface of a wood fibre sheet with a mixture of a fatty drying oil and resin so that part only of the depth is permeated and no coating is formed so that the fibres of the surface are not completely covered, and drying and hot pressing the product. A suitable impregnating liquid is linseed or wood oil boiled with colophony and a drier. The hot mixture is distributed on the surface of the sheet lying on a hot plate and is sucked in by a vacuum acting through the sheet. Alternatively, the liquid is applied to the sheet and caused to penetrate by rollers whose surfaces may be supplied with colour. The Specification as open to inspection under Sect. 91 refers also to the use of the material known under the Registered Trade Mark " Celotex." This subject - matter does not appear in the Specification as accepted.
Patent GB-1333972-A (GB)
Title: Nuclear reactor installations
IPC: G21C7/16
Filed: 1971-05-19
Abstract: 1333972 Controlling reactors BABCOCK & WILCOX CO 19 May 1971 [19 May 1970] 15904/71 Heading G6C A nuclear reactor is controlled by neutron absorber rods which are positioned by fluid power applied in accordance with binary coded command signals in fluidic form and piped to a decoder within the reactor pressure vessel. In an embodiment, the reactivity level of reactor core 11 is controlled by neutron absorber rods, such as 12A, 12B and 12C, movable axially in respective guide passages 13A, 13B and 13C extending within and upwardly beyond the core 11. To ensure sufficient cooling, each of the guide passages 13A-13C is, by means of a restricted inlet 18 and an outlet 19, in communication with the coolant inlet and outlet zones 15, 6. Inlets 18 are sized so as to establish sufficient flow for cooling requirements, but not a flow so great as to shift the rods 12A-12C from their in-core positions. Movement of the rods 12A-12C towards their out-core positions is effected by augmenting the normal steady cooling flow by means of controllers 20A-20C, each being a bi-stable fluidic device having a supply inlet 38, an output 23 in communication via a conduit 21 with a respective guide passage 13A-13C, and an output 24 in communication via a conduit 25 with the inlet zone 15. Flow controllers 20A-20C are responsive to trigger signals in fluidic form at their set and reset inputs 26, 27. A trigger signal applied to set input 26 causes the supply input 38 to be put in communication with the output 23, producing augmented flow in the corresponding guide passage 13A-13C, while a trigger signal applied to reset input 27 causes the supply input 38 to be put in communication with the output 24. Upon failure of coolant circulation, the rods drop to the in-core positions to effect reactor shutdown. The trigger signals are generated by a decoder unit 30, situated inside the reactor pressure vessel 33, and applied to the controllers 20A-20C through conduits 31. Decoder unit 30 has command signal inputs 32A-32H which carry command signals to the unit, the signals being presented as a series of command words expressed in binary coded fluidic form. With the command signals in parallel logic form and with eight inputs 32A-32H, allowing one bit of a command word for commanding the direction of rod movement, a total of 2<SP>7</SP> or 328 rods can be addressed. Alternatively, the command words may be transmitted as a series of fluidic signals in which case the number of command signal inputs may be reduced to two, although, unless the signal frequency is increased, the number of control rods that can be addressed in unit time is reduced.

Title: Signal detection apparatus
IPC: H04N9/455
Filed: 1973-04-04
Abstract: 1422202 Gate and store circuits; colour television RCA CORPORATION 4 April 1973 [10 April 1972] 16024/73 Headings H3T and H4F To distinguish from noise &c., the output of a signal detector 22 is sampled and stored by separate circuits 34, 35 at different times in an operating waveform and the two stored voltages are then subtracted. During the colour burst portion of a chroma signal waveform fed to the detector 22, which acts as a synchronous amplitude detector receiving a reference oscillation from 27, the detector output across R32 is sampled at T39 and stored at C41. During the rest of the waveform (colour subcarrier period) the chroma signal is suppressed and the detector output is sampled at T48 and stored at C50 to provide a reference level representing quiescent circuit conditions, voltage supply variations, noise &c. The difference between the stored voltages is derived in a differential amplifier T57, T58 and is used both to control the gain of the chroma amplifier 21, and also to drive colour killer circuits (120, 121, Fig. 3, not shown). In the detector circuit, T23, T24 receive the push-pull colour burst signal from 21, and are disabled for the rest of the chroma signal by T64, T65. Oscillator driven transistors 28; 31 and bias-driven transistors 29, 30 respectively develop the detected signal across R32 during burst time, and a quiescent voltage otherwise. The burst sampling circuit includes an emitter coupled pair T44, T45 of which T45 is turned on by a signal A during the burst period, so turning on T39. C41 can then be charged by T39 or discharged by T45 so that its voltage follows changes in R32 voltage. The resistor 42 does not appear in the reference bias sampling circuit 35, which is otherwise similar. R42 slightly unbalances a differential comparator T57, T58 which subtracts the stored voltages, and thereby extends its linear operating range.

Title: Improvements in or relating to the mechanical production of oscillation tracks, particularly sound tracks on carriers
IPC: G11B3/00
Filed: 1934-06-01
Abstract: 434,895. Recording sound &c. PHILIPSMILLER NAAMLOOZE VENNOOTSCHAP, Emmasingel, Eindhoven, Holland. June 1, 1934, No. 16403. Convention date, June 2, 1933. [Class 40 (ii)] A method of recording sound or like vibrations on a carrier, as a track having depth variations and corresponding variations of width, is characterized by the use of a flexible or resilient guide or runway, having a resonance in the upper part of the frequency zone to be recorded, and adapted to be deformed by the recording member in such manner that the angle between the cutting edge thereof and the carrier varies in accordance with the position occupied by the cutting member. By this means, compensation for the asymmetrical influence of the resistance of the material is obtained. Use is preferably made of a film comprising- a transparent base, a softer transparent intermediate layer, and an opaque outer coating. The device shown in Fig. 6 comprises a conveyer roller 21 over which the carrier film 22 runs, the roller being toothed at one side. At the part where the record is to be produced by the vibratory chisel 23, the roller has formed in it a circumferential recess 24, bridged by a cylinder 25. The size and material of the cylinder (which is made of a resilient substance such as ivory, celluloid, or spring steel) are such that during recording the cylinder wall becomes deformed under the influence of the chisel movements, so that the angle between the cutting edge and the film surface varies in accordance with the amplitudes of movement of the chisel. This effect is shown diagrammatically in Fig. 11, in which the lines I, II and III indicate three positions of the V-shaped chisel (II showing the zero position), while 29, 30, 31 represent the corresponding positions taken by the opaque covering layer of the film. The natural frequency of oscillation is preferably about 5000 cycles per sec. Instead of making the part 25 of the roller of resilient material such as those specified above, the whole roller may be made of such material. In applying the invention, the soft intermediate layer of the carrier may be thinner, and consequently the chisel angle greater, than usual. Two modifications are described, Figs. 8 and 9 (not shown), in which the roller comprises two flanged parts clamped together with their flanges opposed to form an annular gap below the recording tool; the flanges are so constructed as to have the required natural high frequency. As another alternative, a curved stationary runway formed by two separated tongues may be used.
