Title: Submarine mine anchors
IPC: B63G6/00
Filed: 1974-05-06
Abstract: 1418276 Anchored mines THULINVERKEN AB 6 May 1974 [10 May 1973] 19737/74 Heading B7A [Also in Divisions B8 and F2] To anchor a mine 2 at a preselected depth the mine, after it has been launched, initially floats on the surface whilst its anchor 1 sinks to the bottom as a mooring cable 14 unwinds from a winch drum 8 carried by the anchor 1 under the control of a brake shoe and, after the anchor has sunk to the bottom, a pneumatic jack drives the winch drum 8 until a predetermined length of cable (corresponding to the preselected depth) has been hauled in whereupon a cable stopper mechanism (not shown) is released to arrest the cable and the remaining air supplied to the jack is exhausted. Pneumatic jack. Drive system (see also Division F2).-The jack has a cylinder which is reciprocated by alternately supplying compressed air from bottles 13 to either end via a directional control (not shown) itself switched between two positions when either one of two tappets carried by the jacket abuts against a tappet operated directional control valve. The reciprocatory motion of the jacket is translated into unidirectional rotary motion of the winch drum 8 by two spur gears rotatably mounted on the shaft 9 of the drum 8. The spur gears engage a drive disc keyed to the shaft 9 and are rotated by respective racks carried by the cylinder of the jack. Between the abutting faces of the gears and drive disc are detents which only allow drive from the gears to be transferred to the disc in one rotational direction. Prior to hauling in the cable 14, the cylinder is at one extreme end of its travel and in this position, the drive disc abuts the brakeshoe and the two gears are spaced from the drive disc by two wedges to permit the drum to rotate and unwind the cable 14. Cable stopper mechanism (see also Division F2).-As the cable is wound on to the drum 8, it passes over a pulley 16 carried by an arm 21 pivoted in a housing 22 to permit the pulley 16 to traverse across the drum 8. The rotation of the pulley 16 causes the retraction of a spindle into an axial bore within the pulley's shaft and when the outer end of this spindle has retracted a certain distance, it releases a cable stopper (Figs. 6 and 7, not shown), also pivoted to the arm 21. At the same time, the pivotal movement of the stopper opens a valve to vent air bottles 13. The amount by which the spindle initially extends and thus has to be retracted before the stopper is released is preset in accordance with the preselected depth.

Title: Improvements in or relating to electric signal generating arrangements having provision for frequency control
Inventor: HADLEY JOHN
IPC: G01S7/40
Filed: 1961-06-02
Abstract: 1,019,943. Automatic frequency control. GENERAL ELECTRIC CO. Ltd. May 30, 1962 [June 2, 1961; Sept. 15, 1961], Nos. 20082/61 and 33264/61. Heading H3A. In a signal generating arrangement means are provided for controlling the frequency of operation of the generator to a value substantially equal to that of a signal supplied to the arrangement in short bursts from an external source. The external source may be a radar transmitter and the arrangement may supply an output signal from which a simulated return pulse is obtained for testing the radar system. The generator, backward wave oscillator 2, is approximately adjusted by manual frequency control 4 to the frequency of the radar system 1. A pulse generator 24 operates at the pulse recurrence frequency of the radar system and via phase splitter 25 and relay contacts R2, which change over at a frequency which is a submultiple of the P.R.F., supplies continuously a sequence of positive pulses followed by a sequence of negative pulses to a frequency control electrode of the B.W.O., each pulse occurring during the pulse period of transmission of the radar system. The output of the B.W.O. shifted in frequency above or below its normal value depending on the polarity of the applied pulses is applied with the radar signal to a mixer 3. The output of the mixer being a series of pulses at P.R.F. and having an amplitude which is a function of the comparison between the B.W.O. and radar frequencies is amplified and applied to a pulse stretcher 8 which includes a capacitor charge circuit which is switched to one or other of two capacitors in synchronism with the switching of relay contact R2. During one switch period the pulse stretcher provides a steady output having an amplitude which is a function of the frequency comparison when the B.W.O. frequency is shifted below its normal frequency and during the other period it provides a steady signal having an amplitude which is a function of the comparison when the B.W.O. is shifted above its normal frequency. This substantially square wave output signal is applied via an A.C. amplifier to a phase splitter which includes a phase reversing output contact R1 also synchronized with relay contact R2. The switch supplies a D.C. output having an amplitude and polarity which is a function of the amount and sense of the deviation of the normal frequency of the B.W.O. from the radar frequency. This output is smoothed in integrator 23 and supplied as an automatic frequency control voltage to the B.W.O. During the period between radar pulses the B.W.O. supplies an output from which a simulated return radar pulse can be obtained.

Filed: 1925-08-13
Abstract: 258,060. British Dyestuffs Corporation, Ltd., and Hodgson, H. H. Aug. 13, 1925. Chloro- and nitro-chloro derivatives of mhydroxybenzaldehyde. - 2-Chloro-3-hydroxybenzaldehyde is prepared by dissolving m-hydroxybenzaldehyde in glacial acetic acid, and passing in chlorine till the necessary increase in weight is attained. The 2-chloro aerivative crystallizes out on standing, and the solution on evaporation yields a mixture of the 2-chloro and 6-chloro derivatives, which can be separated by treating with hot aqueous sodium carbonate which dissolves the 2-chloro-derivative. The 6-chloro-derivative is removed with ether on cooling. 2 : 6-Dichloro- 3-hydroxybenzaldehyde is obtained by further chlorination of the 2-chloro-derivative in glacial acetic acid. If 2-chloro-3-hydroxybenzaldehyde is nitrated in 50 per cent acetic acid and the product cooled and filtered, 4-nitro-2-chloro-3- hydroxybenzaldehyde is obtained. If, however, the mixture after nitration be diluted and the product filtered, a mixture of the 4- and 6-nitro- 2-chloro-derivatives are obtained which can be separated by steam distillation. Nitration in acetic acid of the 2 : 6-dichloro-derivative gives 4-nitro- 2 : 6 - dichloro - 3 - hydroxybenzaldehyde, which, if the acetic acid is of the strength of 5 parts of glacial acetic acid to one of water, separates in crystalline form.
