Abstract: 1415408 Moulding hulls WILLARD BOAT WORKS 9 Feb 1973 [10 Feb 1973] 6607/73 Heading B5A A large glass fibre reinforced plastics (g.r.p.) boat hull is made by curing a layer of g.r.p. placed on the non-stick surface of an upwardly concave split mould 10 comprising two major sections with two or more removable sections 23 adjacent the adjoining edges of the major sections; removing the removable sections and supporting the cured hull at the portions thus exposed; separating the major mould sections from the mould and moving them away to permit withdrawal of the hull in a generally horizontal direction. The mould sections are bolted together along peripheral flanges 22, 24 the removable sections being omitted initially to provide openings for a ventilating fan and for passage of men and materials. Blocks 21 and shoring (not shown) stabilize the mould. Removable sections to form windows and recesses for rails and fittings are fixed to the mould. A wax or water soluble pasting agent is applied to the polished face of the major mould sections, followed by a white and a black polyester gel coat and several layers of glass fibre cloth and rovings with polyester resin, utilizing the walkways 31 on scaffolding 29 suspended from the top of the mould 10. The removable sections 23 are then attached and g.r.p. laid over them and feathered into the remainder before curing. After curing sections 23 are removed from the hul using air or water applied through fittings 26. Blocks 35 (Fig. 7, not shown) are placed under the keel and wedged until they take the weight of the hull, and shoring (34) is applied to the exposed parts of the hull. The major mould portions are then separated from the hull by air or water and wedges and wheeled away. The mould is made by placing layers of g.r.p., balsa, and g.r.p. on a waxed former and incorporating hollow stiffening ribs 14 and wheeled support legs 18.

Abstract: 680,424. Automatic gain control. PHILIPS ELECTRICAL, Ltd. March 3, 1948 [March 6, 1947], No. 6700/48. Class 40 (v). [Also in Group XL (b)] In a photo-electric image transmission system (see Group XL (b)) employing line-by-line scanning and in which pulses A, Fig. 2, corresponding to whiter-than-white and further pulses B corresponding to blacker-than-black are added to the transmitted signal train C at the end of each line, the receiver has a circuit comprising two oppositely-connected rectifiers in series with two condensers arranged to derive a potential proportional to the difference U between the pulses A and B, the potential being employed, according to one aspect of the invention, for automatic gain control, whereby the reproduction of the received image is maintained within a desired range of intensity. In Fig. 4, the received signals at 1 are applied to an amplifier 5 which feeds a final valve 15 controlling a glow-discharge tube 18, 19 to reproduce the image photographically. In accordance with the invention, the signal range U is controlled to remain within the marking range of the grid characteristic of valve 15 by a peak-to-peak measuring circuit connected to the cathode of valve 5 comprising biased diodes 23, 26 and condenser 28, 29. The potential across resistor 30 and milliammeter 31 corresponds to the difference U and may be applied to the grid circuit of one or more earlier amplifier stages to effect the automatic control.

Title: Improvements in frequency multiplier
IPC: H03K5/156
Filed: 1947-03-11
Abstract: 639,556. Valve circuits. BENDIX AVIATION CORPORATION. March 11, 1947, No. 6800. Convention date, April 30, 1946. [Class 40 (vi)] In a frequency multiplier in which a train of pulses derived from a sinusoidal source are fed to an amplifier having a feedback path including a delay network, the delay period is adjusted to be an integral submultiple of the pulse repetition period so that the output pulse train which may be converted into sinusoidal waveform has a frequency which is a multiple of that of the input source. The Figure shows a pulse generator 14 which is synchronized from a sine wave oscillator 10, the pulses then being fed into an amplifier 20 which has a feedback path associated with it comprising a delay network 24. The delay time of the network is adjusted to be an integral sub-multiple of the pulse repetition period by varying the delay, e.g. by varying capacitors 52, 54 until a dip is obtained on the amplifier output current meter 30. The output pulse train which has a repetition frequency which is a multiple of that of the input pulse train is amplified in a Class C amplifier 34 having an output circuit 42 which is tuned to the required multiple frequency to produce a sinusoidal output voltage across coil 48. The variable capacitors 52, 54 of the delay network and that of the tuned output circuit are preferably ganged so that they can be tuned together to a given output frequency. In a modification, Fig. 2 (not' shown), a blocking circuit is included which is synchronized from the pulse generator and renders the feedback circuit of the amplifier inoperative during any given portion of the input pulse interval. Thus any given pulse of the input pulse train will be followed by a given number of pulses which have been delayed in the delay network and then by an interval before the commencement of the next pulse of the input train.

To clear a selected store, say 1a, a long negative pulse is applied via lead 9a simultaneously with the application of a long pulse to the second input of a gate 21a which is thus opened and which effectively shortcircuits every tube in store 1a thus clearing the store.

A centrifugal pump comprises an impeller having balance passages leading from the impeller eye to a space adjacent the side of the impeller remote from the eye, an exhaust connection to the space, and rotatable vanes in the space. The pump shown is primed by withdrawing air from the impeller eye 24 via balance holes 28 and an annular space above the impeller, by means of an air pump (not shown) communicating with the annular space. Any liquid leaking past wear rings 26 into the annular space and tending to prevent complete removal of the air is mixed with the air by means of rotating vanes 29 to form an air-liquid mixture which can be withdrawn by the air pump. The vanes 29, which also reduce the leakage past the wear rings 26, are radial or curved and extend between the impeller hub and an annular flange 27 which also carries the inner wear ring 26. The vanes 29 may instead be carried by the impeller shaft 15. After removal of an elongated coupling 19 which connects the impeller shaft 15 to the motor shaft 20, cover plate 5 can be unbolted from the pump casing 1 and the cover plate, impeller and impeller shaft can be raised as a unit and then removed through a large opening at one side of the motor pedestal 21.
