(Representative of Bayliss, L.), 96, Grand Drive, Raynes Park, and BUCKLAND, W., 5, Jane Street, Blackfriars Road, all in London. Nov. 7, 1929, No. 34022. [Class 79 (iii).] A trailer draw-bar G is mounted between a pair of pivoted links N so that a forward pull against a retracting spring J causes the front end to dip imparting downward pressure to the rear wheels of the tractor. The draw-bar, which may be of tubular or hollow formation affording passage for a brake operating cable s, is preferably carried by a forecarriage B connected to the trailer chassis A by a turnplate with a peripheral connection C to avoid the use of a king pin, a spring catch T locking the parts when the draw-bar moves into alignment. Brackets D, E, connected by one or more stays F depend from the turnplate. The draw-bar passes freely through the front bracket E between renewable thrust plates R and at its rear end carries a rod H bearing the retracting spring J, the rod and spring passing through a gripping sleeve d<1> trunnioned in the rear bracket D. The spring is confined between an endplate g<1> and nut M, the rod H passing through the plate g<1> and being secured to an inner plate or abutment g<2> enabling the compression of the spring to be regulated by adjustment of the end nuts M, g<3>.

Abstract: 769,038. Transformers. BENDIX AVIATION CORPORATION. Nov. 30, 1954 [Dec. 1, 1953; June 9, 1954], No. 34686/54. Class 38 (2). In an inductive coupling, the output voltage of which varies in a desired non-sinusoidal relationship with relative angular movement of primary and secondary windings of the coupling, e.g. as shown in Fig. 3, the secondary winding includes a series of coils lying in slots with the same or a different number of turns N1-N4 and a different slot pitch for each coil, the coils all being symmetrical about an axis normal to the axis of rotation. The coil turns are distributed in a manner which is calculated by a method which involves solving a number of simultaneous equations. Each equation represents a different harmonic of the non-sinusoidal relationship, as derived by analysis into a Fourier series. The unknown quantities of each equation are the number of turns in coils whose number and angular spacing # has been predetermined, the number of equations and of coils being the same. Each equation includes as parameters, functions of the displacement angles, and the coupling factors of the various coils. The latter which depend on the mechanical configuration of the coupling, may be known by experience, or may be determined by iteration, one set of equations with assumed coupling factors being used to obtain turn distributions which are employed in an actual construction of transformer. From the waveform obtained a new set of equations is derived, giving another set of coupling factors. This process may be repeated as necessary. Specifications 671,632 and 680,503 are referred to.

Title: Improvements in the treatment of cotton, linen and rayon fabrics
Inventor: MILLER WILLIAM STUART
IPC: D06Q1/08
Filed: 1966-08-03
Abstract: The wet and dry crease recovery properties of a fabric consisting wholly or partly of cotton linen or viscose rayon are improved by (1) impregnating the fabric with 50-150% by weight of an aqueous solution containing at least one nitrogenous cellulose reactant resin and an acid suitably buffered so that the solution has a pH of 0.5-3.  (2) partially drying it to a residual moisture content of above 6% by weight, (3) holding it in a smooth crease-free condition for at least 2 hours at a temperature of 10 DEG -50 DEG C during which time reaction takes place while the fibres are still in a swollen state, (4) heating it at 90 DEG -150 DEG C. for 1-5 minutes either with or without intermediate drying, (5) washing it in aqueous alkali e.g. sodium carbonate and then water to remove the acid and any unreacted material and (6) drying it. The nitrogenous cellulose reactant resin may be dimethylol cyclicethylene urea, dimethylol-1, 3-propylene urea, dimethylol dihydroxyethylene urea, dimethylol 4-methoxy, 5-dimethyl propylene urea, dimethylol hydroxy propylene urea or dimethylol methoxyethyl carbamate.  Suitable buffer systems are mixtures of sulphuric acid and sodium dihydrogen phosphate, hydrochloric acid and sodium acetate, citric acid and disodium hydrogen phosphate. The treating solution may also contain a polyethylene emulsion softener.  After partial drying the fabric may be wound on to a mandrel to form a roll and covered with a polyethylene sheet to prevent drying of the fabric during the lying period.

Title: Improvements in and relating to hand grenades
IPC: F42B27/08
Filed: 1937-12-15
Abstract: 485,739. Hand grenades. JANECEK, R. Dec. 15, 1937, No. 34782. [Class 9 (i)] The detonator 4 of a hand grenade is mounted on a plate 2 carried by a longitudinal spindle 1, and the firing pin 9 is carried by a mass 7 which is slidably mounted on the spindle and which is urged towards the detonator by a spring or springs 8. Further, the pin is normally prevented from striking the detonator by a tube 27 on a lever 24 which is automatically swung aside to uncover the detonator when the pin is withdrawn from the tube by centrifugal force when the grenade is whirled before throwing. In the construction shown, the disengagement of the firing pin from the tube, during transport, is provented by pins 22 which limit the outward movement of the mass 7. These pins are carried by a body 18 mounted in the cap 17 of the grenade. Before the grenade is thrown the body 18 is pulled by hand to a position in which spring-urged balls 20 carried thereby fit into an outer recess 21 of the cap. In this position, the pins 22 are out of the path of the mass 7. When the grenade is whirled, the mass is urged outwardly against the action of the springs 8 and is temporarily held in this outward position by spring-pressed balls which engage in recesses 11 of the spindle 1. The firing pin is then clear of the tube 27 and the lever 24 is urged by a spring 26 to a position in which the detonator is uncovered. The lever normally constitutes an abutment for a locking pin 6 actuated by a thumb-piece 31 but, when rotated by the spring 26, is moved clear of the pin. If, after whirling, the grenade is not thrown the locking pin is moved by the thumb-piece to a position in which it forms an abutment for a pin 10 on the mass 7 and thus prevents the firing pin from striking the detonator.

[Also in Division H1] In a power amplifier, comprising at least one power stage having a plurality of transistors 1-6 connected and fed in parallel and being simultaneously driven by an input signal applied to a common input terminal 7 connected to similar electrodes of the transistors, a transformer 18 is provided having a single secondary winding connectible to a load and a plurality of primary windings 21-26 corresponding in number to the transistors and each primary winding is connected to the output electrode of a different one of the transistors. The circuit shown is a power amplifier of a transmitter feeding an aerial 27 which is tuned by capacitor or inductor 20. Protection resistors 41-46 are provided in the collector circuit of each transistor to prevent thermal runaway and to limit their collector current as does resistor 29 which is switched out of circuit by switch 30 when the amplifier is receiving a signal which may be low, very high or ultra-high frequency. The parasitic admittance between the collector and base of the transistors may be neutralized by connecting an impedance 40 between the output and input of the amplifier and by arranging the transformer windings so that the input and output voltages at 7 and 19 are of the same phase but of opposite phase to that at the collectors. Negative temperature coefficient resistors or thermistors can be included in the collector circuits of the transistors to regulate the circuit against temperature changes. An inductor L in anti-oscillation elements 11-16 damps oscillations which may be produced by parasitic coupling in the circuit of a transistor or between different transistors. Several amplifiers of Fig. 1 may be connected in parallel (Fig. 2, not shown). Measurement and testing.-The current flowing through each collector circuit of the transistors may be measured in turn by switching a voltmeter calibrated in current across shunt resistors 51-56 in each collector circuit. Transformer construction and circuit mounting.-The transistors are mounted on a conductive earth plate (61, Figs. 3 and 4, not shown), around a toroidal transformer which has a coaxial output (57, 58) from a single turn secondary around which the primary windings 21-26 are wound.
