Title: Improvements in and relating to automatic firearms
IPC: F41A3/70
Filed: 1940-04-06
Abstract: 598,227. Automatic guns. BREVETS AERO-MECANIQUES, SOC. ANON. April 6, 1940, No. 6248. Convention date, Oct. 14, 1939. [Class 92 (ii)] Relates to automatic guns of the kind in which the breech-block 6 is held in firing position by a pivoted locking-bolt 7, itself held in locking position by inclines 8 on a safety device in the form of a striker-post 9 having limited motion relatively to the breech-block, all as described for example in Specification 515,248. According to the invention, rebound of the breech-block from its forward firing position is prevented by a forwardly sliding mass M which acts to resist movement of the safety device rearwardly to a position in which it releases the locking-bolt 7.

Title: Improvements connected with beer and wine casks and like containers
IPC: B65D81/18
Filed: 1935-02-28
Abstract: 454,325. Casks with cooling means. ALLEN, B., 25, Park Avenue, Solihull, Warwickshire. Feb. 28, 1935, No. 6336. [Class 29] [See also Group XVII] The temperature of the contents of a cask is controlled by a removable flexible jacket of low heat conductivity and having in its walls a tubular circulation space or system connected to a heating or refrigerating source. The jacket consists of two sections 2, 3, each section comprising a foundation layer 4 of rubber, enclosing a series-connected liquid circulation system 5, a wall 6 of sponge rubber vulcanized to the layer 4, and a thin covering 7 of rubber or rubberized fabric. The sections are connected by webs 8 integral with, or vulcanized to the layer 4, and which admit of access to the spile 9. The ends of flexible strips 16, (e.g. of spring steel or cane) provide anchorages for adjustable securing straps 18, and also retain in position, flaps, Fig. 4, (not shown), which cover the cask ends. These flaps may be separate from, integral with, or vulcanized to, the layer 4, and one is provided with an opening to give access to the tap hole. Each foundation layer, with or without the external coverings, may have a single passage, or several longitudinal or circumferential passages, independent of each other, or connected in series, or formed as a volute.

Title: Improvements in auxiliary gear, particularly mole-draining gear for tractors and other vehicles
Filed: 1932-03-03
Abstract: 397,916. Stands or supports for -tractors ; winding and propelling gear; anchoring devices. MOXONS, Ltd., Whetstone, London, and SHEPHERD, J. N. K., Mymswood Cottage, Shepherd's Way, Potters Bar, Middlesex. March 3, 1932, No. 6440. [Classes 79 (i), 79 (ii), and 79 (iii).] A combined jacking and ground-anchor device for tractors comprises a frame 5 pivoted to the vehicle and adapted to be brought under the vehicle into a position, shown in broken lines, in which it anchors the vehicle and jacks the driving wheels 19 clear of the ground. The frame 5 comprises a pair of channel members pivoted on a rod 1 and connected near their lower ends by an angle bar 7 which forms a stop and prevents the members 5 sinking beyond the bar 7. Spade members 9 are fixed to the lower ends of the members 5. The device is particularly intended for use with mole-draining gear in which a mole plough is attached to a rope 28 wound on a drum 11 driven from the tractor driving gear. To anchor the tractor it is driven backwards until the spades 9 dig into the ground and stop further movement. The drum 11 is then driven so as to haul on the rope 28 and the tractor is drawn backwards until the members 5 are vertical and come against stops 10. The drum 11 is driven by double chains 15 from twin sprockets 16 on a normal kind of back axle 18 adapted or converted for use as a countershaft, this axle being mounted in brackets 27 on the frame 3. The road wheels 19 are mounted on a dead axle 23 adjustably mounted in brackets 25, and are normally driven by two pairs of chains 21 at each side of the tractor, these chains passing over sprockets 16, 22 on the countershaft. When the drum 11 is to be driven the outer chains are removed from the driving wheel sprockets and the drum shaft 12 is connected by chains 15 to the sprockets 16 so that the propeller shaft 17 now drives the road wheels and the drum 11. If desired, a clutch may be provided in the drive to the drum 11. Adjustable torque rods 26 are provided between the brackets 25 and the frame 3 or the brackets 27. The drum shaft 12 is adjustable for chain-tensioning purposes.

Title: Improvements relating to electrical communication systems
IPC: H04B1/56
Filed: 1945-03-15
Abstract: 589,159. Two-way transmission. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. March 15, 1945, No. 6574. [Class 40 (iv)] [ALso in Group XL] In an electrical communication system, a cathode-ray beam traces a regular path over a composite target area and message signals are transmitted by displacing the trace to produce current changes in circuits associated with the target. Fig. 1 shows an arrangement in which the cathode-ray beam traces a straight line path under the influence of a symmetrical saw-tooth waveform applied to deflection plate VP through transformer TR1 at a recurrence frequency much greater than the frequency of the message signals to be transmitted. Shift controls VR1, VR2 are adjusted to make the trace lie symmetrically over the two segments of the target in the absence of input signals, so that the output in balanced transformer TR2 is zero. Message signals from input transformer TR3 are fed in push-pull to separate deflection plates VSP to upset the symmetry of the trace relative to the target in accordance with the amplitude and polarity of the signals so that equivalent oscillations occur in transformer TR2. In Fig. 2 (not shown), a rectangular trace is produced by feeding symmetrical sawtooth waveforms in quadrature to separate deflection plates HSP disposed at right angles to plates VSP and with similar shift arrangements. The rectangular trace may be used to provide two-way transmission by arranging the target in four segments as shown in Fig. 3, and feeding input and output signals through conventional hybrid transformers T9, T10 coupled to balancing networks BI, BO. During forward transmission, the trace is influenced by plates VSP and the output from segments t1, t2 appears only across terminals O, a null effect being produced in transformer TR6 so that plates HSP are not energized. During reverse transmission deflection plates HSP are effective and the output is taken from segments t3, t4. Specifications 567,451, 567,674 and 589,158 are referred to.
