Title: Improvements in or relating to cable or rope cleats or clamps
IPC: B66D3/10
Filed: 1947-02-25
Abstract: 621,657. Rope stopper. TOWNSEND, C. M., TOWNSEND, C R., and ECCLESTON, J. T. Feb. 25, 1947, No. 5395. [Class 78 (ii)] A rope stopper comprises a pulley 5 around which the rope is reeved; an anchoring and gripping lever 2 to anchor the pulley to a fixed point and to cause the rope to be gripped when the rope is pulled; and a separate spring-loaded hand lever 4 fulcrummed at 10 to the pulley housing and connected (e.g. at 3a) to the inner arm of the anchoring and gripping lever to effect release of the grip on the rope. As shown, rope 20 passes round pulley 5 housed in pulley housing 1, which housing has anchoring lever 2 pivoted thereto at 7 and is secured thereby to fixed point 12. To the bifurcated end of lever 2 is pivoted brake grip 3 by means of pin 3a, the ends of the pin passing through slots 8 in the pulley housing, so that when the rope is pulled there is a tendency for the pulley 5 and lever 2 to align themselves and thus, cause grip 3 to grip the rope 20. Additionally, hand lever 4 is fulcrummed at its bifurcated end 10 to the pulley housing 1 and comprises slots 4e in which the ends of movable pin 4a move, so that as hand lever 4 is moved to the left or right the pressure of grip 3 is increased or decreased. Spring 20a between levers 2 and 4 serves to maintain a predetermined pressure upon the rope.

Patent GB-706816-A (GB)
Title: Process for making 2-methyl-5-ethyl pyridine
Filed: 1952-03-05
Abstract: 2-Methyl-5-ethyl pyridine is produced by reacting aldehyde and ammonia by charging aqueous ammonia to a pressure vessel, heating it to a temperature at which ammonia and acetaldehyde react, slowly introducing acetaldehyde into the vessel, the total amount of acetaldehyde being less than that theoretically required to react with the ammonia and maintaining the reaction temperature until the reaction is complete.  The reaction may be carried out at temperatures in the range 180 DEG  to 300 DEG  C.  Preferably the amount of ammonia used is between 3.2 and 10 times the theoretical quantity necessary.  It is desirable that after the acetaldehyde has been added the reactants should be heated at a higher temperature.  A catalyst may be used for the reaction, suitable catalysts being ammonium acetate, ammonium salts of other carboxylic acids, ammonium carbonate, ammonium chloride or sodium acetate.

Title: Improvements in and relating to the preparation of substituted aralkanolamine and derivatives thereof
Inventor: ADAMSON DONALD WALLACE
IPC: C07D295/08
Filed: 1948-02-27
Abstract: Amines of the formula <FORM:0657302/IV (b)/1> (in which R1 is an aryl group which may be substituted by alkyl or alkoxy groups, R2 and R3 are hydrogen atoms or an alkyl radical, R4 is hydrogen, R5 is hydrogen or an alkyl radical and R6 and R7 may be the same or different alkyl, alkenyl or aralkyl groups or -NR6R7 may be a pyrrolidino-, morpholino- or piperidino group) are prepared by treating with one another the corresponding b -aminoethyl aryl ketone or a salt thereof and the appropriate alkyl magnesium halide or organo-lithium compound and hydrolysing the organometallic compound produced.  The reaction is preferably carried out in an anhydrous mutual solvent by allowing to stand or by heating until reaction is complete.  The product is hydrolysed, suitably by addition of water followed by acetic acid, to give a salt of the base, which, if insoluble, may be separated by filtration and converted to the free base by treating with aqueous alkali, or if soluble in the reaction mixture, is basified with aqueous alkali, and extracted with an organic solvent which is subsequently evaporated.  The 3-aryl-3-hydroxy alkyl tertiary amines formed may be converted into the corresponding quaternary salts by treatment with an alkyl or aralkyl halide.  The quaternization may be effected in a solvent such as acetone, methanol, ethanol or dioxane.  In examples the following compounds are prepared in each case by means of the Grignard reaction: (1) 1-N-piperidino-3-phenyl - nonan - 3 - ol; (2) 1 - dimethylamino - 3 - phenyl - butan - 3 - ol; (3) 1 - N - piperidino-3 - phenyl - 4 - methyl - pentan - 3 - ol; (4) 1 - N - piperidino - 3 - phenyl - heptan - 3 - ol and its salt with methyl iodide; (5) 1-N-piperidino-3-phenyl-pentan-3-ol, and its hydrochloride; (6) 1 - N - piperidino - 3 - phenyl - hexan - 3 - ol, and its hydrochloride; (7) 1-N-piperidino-3-phenyl-octan-3-ol, and its hydrochloride; (8) 1 - N - piperidino - 3 - phenyl - decan - 3 - ol, and its hydrochloride; (9) 1-N-piperidino-3-phenylundecan-3-ol, and its hydrochloride; (10) 1-diethylamino - 3 - phenyl - octan - 3 - ol, and its hydrochloride; (11) 1-dibutylamino-3-phenylhexan-3-ol, and its hydrochloride; (12) 1-N-piperidino-3-p-tolyl-hexan-3-ol, and its hydrochloride.

Title: Improvements in scan tuning circuits for automatically tuned radio receivers
IPC: H03J7/20
Filed: 1969-02-04
Abstract: 1,203,906. Radio receiving circuits. GENERAL ELECTRIC CO. 4 Feb., 1969 [29 Feb., 1968], No. 6060/69. Heading H3Q. A stop on signal receiver is tuned by means of varicap diodes 3, 4 which are swept over the tuning range by the charging of capacitor 20 from source G. Interposed between source 9 and capacitor 20 are the series-connected collector to emitter paths of transistors 21, 31 which are biased conductive in the absence of a signal. When a signal is intercepted, sharply. tuned I.F. amplifier 11 produces an output which is rectified by diodes 23, 33 to generate biases which cut off transistors 21, 33, terminating the tuning sweep. Diode 23 is coupled to transistor 21 via a short time-constant circuit, so that cessation of tuning is rapid: diode 33, however is coupled to transistor 33 via a long timeconstant circuit, comprising capacitor 34 and resistor 35, so that momentary cessation of the signal does not cause the tuning scan to recommence immediately. The tuning scan can be caused to recommence by closure of ganged switches 26, 36 and when complete the system is returned to the initial state by means of unijunction transistor 30, which discharges the capacitor 20.

Title: Improvements in or relating to semiconductive devices
IPC: H01L21/00
Filed: 1956-02-28
Abstract: 826,744. Transistors. PHILCO CORPORATION. Feb. 28, 1956 [May 13, 1955], No. 6151/56. Class 37. A transistor comprises a semiconductor body provided with opposed area emitter and collector contacts one at least of which has an inner boundary curved so that the spacing between the inner boundaries over a major part of the confronting boundaries is at least twice the minimum spacing. The transistor shown in Fig. 1A comprises a base body of 0.1 ohm. cm. N-type Ge in which pits 14 and 15 have been formed and emitter electrodes 11, 12 of, e.g., In deposited by the electrolytic etching and plating techniques described in Specification 805,291. Spring or soldered-on contacts may be made to the electrodes. The emitter and collector pits are spheroidal and have radii of 2 and 4 mils. respectively, the minimum spacing of the electrodes being 0.05 mils. Alternatively the collector electrode may be deposited on a planar or slightly convex surface. In either case dedepressions of very high curvature may be formed in the centres of the pits. e.g. by etching with a smaller jet so that the minimum spacing is confined to a very small region. The socalled area contacts may be replaced by deposits of impurity material characteristic of the opposite conductivity type to that of the body fused to the body to form PN emitter and collector junctions. Electrodes having more than one region of minimum spacing may also be used. The devices are suitable for amplification at frequencies up to 250 Mc/s. with suitable operating bias because of their low base resistance. The difference in minority carrier transit times due to the non-uniform spacing of the emitter and collector has little effect on the operation since the bulk of the current flow is confined to the small area of minimum spacing on account of the much higher diffusion field there. By increasing the collector bias the device may be made to operate in the " avalanche " mode or in the " punch through" mode, that is where the emitter and collector space charge regions overlap to give a very high electric field which appreciably reduces the transit time, which is therefore suited for highfrequency working. Use of the transistor in an oscillator circuit is described. Specification 805,292 also is referred to.
