Filed: 1923-03-28
Abstract: 195.636. Erste Br³nner Maschinen- Fabriks-Ges. March 28, 1922, [Convention date]. Hot-water storage apparatus.-In a steam plant having a greatly varying steam demand, the boiler, which is designed to supply the mean steam demand, is so connected to the steam and water spaces cf a storage vessel that steam may be passed into the vessel during periods of little demand, and steam may be taken from the vessel for use in the consumers supplied by the boiler during periods of great demand. The steam and water spaces of a boiler K supplying steam to, say, a turbine T through a superheater l are connected by pipes e, c to a vessel V, from which stored steam mav be taken through a superheater m and supplied to the turbine by a pipe s. Valves f, d in the pipes e, c are closed while steam is being taken from the storage vessel. Feed-water is supplied through a valve k, which allows the water to pass into either the boiler or the storage vessel or into both. The storage vessel may be arranged below the boiler. A single storage vessel may be used in connection with a number of boilers, or a separate storage vessel may be used in connection with each boiler of a battery.

Title: Automatic anti-skid control system
IPC: B60T8/58
Filed: 1969-02-19
Abstract: 1,208,843. Anti-skid braking systems. BENDIX CORP. 19 Feb., 1969 [13 March, 1968], No. 8942/69. Heading F2F. In a road-vehicle anti-skid braking system, wheel deceleration and acceleration signals energize solenoid valves at predetermined levels -g; +g 1 ; + g 2 , to control vacuum-actuated regulating valves in the wheel brake pipe. Regulating valve, Fig. 4.-Comprises a spring- loaded diaphragm 310 with a small leak 311, and driving a piston-rod 320. When solenoid 314 is energized (at - g) to admit atmosphere to one side of the diaphragm it moves to the left with rod 320 allowing ball-valve 322 to close the master-cylinder pipe and increases the volume of space 341 connected to the brake pipe 331 (thereby reducing brake cylinder pressure). At a low level of wheel acceleration +g 1  solenoid 314 is de-energized, and leak 311 allows the spring to return the diaphragm and rod 320 slowing pumping fluid back into the brake pipe. If the wheel accelerates to +g 2  solenoid 350 is energized, connecting both sides of the diaphragm through pipe 351 to allow a rapid return to full braking. Skid control system. Fig. 1.-As shown, the front wheels are controlled separately by regulators 14, 15, and the rear wheels jointly by regulator 13. The speed of the wheels is detected by, e.g., tacho-altemators 30-33, and above a minimum slow speed determined by threshold circuits 51, is fed to counters 45 providing a D.C. signal proportional to speed, which is differentiated at circuit 47 to provide the acceleration signal. The value of the acceleration is determined by comparators such as 55, 56, 57. At value - g comparator 55 triggers circuits, e.g. 64, 70, to open AND gate 82, causing the regulator to reduce brake pressure; at value + g 1  comparator 56 inhibits the AND gate so that brake pressure increases slowly; and at value +g 2  comparator 57 controls the regulator to rapidly increase brake pressure. Rear wheel control is determined by a differential amplifier "select" circuit 50 which may be arranged to select either the fastest rear wheel or the slowest rear wheel for the control channel. Suitable transistor circuits are illustrated in Figs. 7, 8 (not shown). Parked/locked wheel discriminator.-Since it is desirable to have normal braking at very low speeds a logic circuit 46 is provided comprising an R.C. delay circuit (142), (143), (158), Fig. 6A (not shown), which keeps the control channel open for 0.4 seconds after the wheel signal drops below threshold value. If the wheel is locked, brake release will allow it to speed up in this time and control the normal antiskid cycle, but if the vehicle is slowing to a stop the wheel' signal will remain below threshold, and the antiskid circuits will not be operative.

Abstract: 1345108 Television NIPPON KOKAN KK 28 Feb 1972 [3 March 1971 (2) 7 May 1971] 9065/72 Heading H4F Apparatus for inspecting the internal surface of a pipe 1, and having means for driving it therethrough, includes a television camera 2 having a lens 21 and a rotatable camera head 14 containing a light source 24 illuminating the surface through a lateral window 22 from which it is reflected on to mirror 23 and then to lens 21. In order to provide a reference point indicating the position of the window with respect to the vertical a spot light 30 is pivotally mounted on the front of head 14, its energizing battery 28 acting as a counter-weight to maintain the light in a vertical position. The light may be adjusted so that the resulting reference spot appears at the top of the display and it may be coloured or caused to oscillate. The apparatus is mounted on castors bearing on the internal surface of the pipe and is driven through the pipe either by a drive unit on the carriage or by a separate device pivotally attached to the back of the carriage. This  carries a reversible electric motor which drives the unit selectively through a high speed or a low speed clutch to which a wheel of the unit is connected by a belt or chain drive. Preferably the apparatus is driven through the pipe until a region of interest is reached, whereupon the device is stopped. The speed of rotation of head 14 may be varied or rotation may be stopped. Preferably the apparatus carries forwardly facing lamps (17), Fig. 2 (not shown), for additional illumination and it is stated that the combined illumination in axial and radial directions enables stereographic images of defects to be formed. The apparatus may be retrieved from the pipe by reversing the driving motor. The drive speed may be continuously variable.

Patent GB-641949-A (GB)
Title: Improvements relating to television and like receivers
IPC: H04N5/18
Filed: 1947-04-03
Abstract: 641,949. Television receivers. COSSOR, Ltd., A. C., and WYNN, A. H. A. April 3, 1947, No. 9168. [Class 40 (iii)] [Also in Group XL (c)] A circuit for a television receiver which provides D.C. restoration and an automatic gain control potential comprises a rectifier and a valve which is " gated " to conduct during the occurrence of synchronizing pulses, connected in shunt with the grid of the cathode-ray tube. In one embodiment, signals are applied to the grid of a cathode-ray tube V2 over a condenser C1 and resistance R2. The resistance R2 is shunted by a valve V3, the grid of which is driven positive during each frame synchronizing period by means of a positive pulse derived from the frame scanning coils. The pulse is arranged to cease while the frame synchronizing, pulse is at its base level, so that the grid potential of the tube V2 is brought to the black level by conduction in the valve V3 immediately prior to the commencement of the video signal. The time-constants C1, R2 and C2, R5 respectively are sufficiently long for this potential to be held and also for the valve V3 to remain at cut-off between frame synchronizing periods, being biassed by the charge on the condenser C2 due to grid current during the application of positive pulses. The negative-going . synchronizing pulses are passed by a diode D and charge a condenser C3 from which A.G.C. potentials are taken via an adjustable potentiometer R7 and a filter network. A delay bias is obtained by returning resistance R8 to a source of positive potential. In a further embodiment, Fig. 2 (not shown) in which the peaks of the synchronizing pulses are brought to ground potential the diode D serves for D.C. restoration, and its anode is connected to the ground line. Positive gating potentials are applied to the grid of the valve V3 to render it conductive during part of the interval between frames, producing a current in the valve which-is dependent upon the amplitude of the frame synchronizing pulses. This current flows in a resistance connected in the cathode lead and produces a positive charge in a shunting condenser which may be used for A.G.C. Specification 507,239 is referred to.

Title: Improvements in photographically recording sound
IPC: G03C5/14
Filed: 1934-03-23
Abstract: 435,473. Developing sound-films. I. G. FARBENINDUSTRIE AKT.-GES., Frankforton-Main, Germany. March 23, 1934, No. 9171. Convention date, March 25, 1933. Drawings to Specification. [Class 98 (ii)] [See also Group XXXVIII] Relates to the photographic recording of sound by the variable density method, and to the preparation of a positive print from an original negative in such a manner that the product of the gammas of the positive and of the negative may be unity. According to the invention, the negative film is developed to a gradation of # greater than 1, the exposure having been such that the blackenings corresponding to the maximum and minimum lie on the straight part of the characteristic curve ; a print is then made on an undyed film, the exposure being such that the blackening lies on the straight part of the curve, and the development of the positive is such that its y is the reciprocal of that of the negative. In this way, instead of producing from an original having a flat gradation a relatively dense print, as hitherto, a print having a high average transmission is obtained. Graphs are given in the Specification, to explain the principle of the invention, and a specific example of the procedure to be followed is described, with details including formulae of metol and metol-hydroquinone developers.
