IPC: F41A13/12
Filed: 1918-07-02
Abstract: 129,413. Rice, J. T. July 2. 1918. Machine guns.-Consists in providing a Lewis gun with a receiver readily detachable from the barrel casing so that the receiver, together with the barrel, may be withdrawn rearwards, after which the barrel may be readily detached from the receiver. Fig. 1 shows the barrel 13 detachably connected with the receiver 17 by a locking- pin 53. When thus connected, the barrel is pushed forwardly through the radiator 42, and a flange on the receiver is registered by pins 28 with a flange on the barrel casing 15, these flanges being then fastened together over a projecting ring 14 on the barrel by pivoted locking-bolts 20 arranged as shown in Fig. 10. The bolts have right and left-handed screws respectively and are pivoted at 19 to the casing 15 so that, after releasing clamps 23, they may be swung aside through lateral gaps in the flanges to permit of rearward withdrawal of the receiver and barrel from the casing 15. The locking-bolts are each provided with a milled nut 22 and a loose washer 26, between which is loosely mounted the clamping-lever 23. This lever has a diametral projection 24 normally seated in a corresponding groove in the washer. After screwing up the nut, the lever is turned and the parts are clamped as the projection moves out of the groove. The washer is prevented from rotating by pins 27 engaging recesses in the adjacent flange. Fig. 12 shows modified locking-bolts, which are seated at their front ends in the casing flange 15 and hinged for turning aside on pins 51, which lie within the nuts when these are in clamping position. The gas chamber 30 is made integral with the barrel band 31, and the gas-regulator 32 is provided with a spigot 33, which serves to lock the barrel to the casing. The barrel mouthpiece 40 is screwed to the radiator 42 in Fig. 5, instead of to the barrel, so as not to prevent the rearward withdrawal of the barrel. The radiator casing is provided with a split circular band 45 having an internal projection 47, which engages recesses in the upper most radiator fins 44.

Patent GB-836091-A (GB)
Title: Improvements in or relating to arrangements for correcting distortion in start-stop telecommunication systems
IPC: H04L25/24
Filed: 1958-04-03
Abstract: 836,091. Telegraph regenerative repeaters. SIEMENS & HALSKE A.G. April 3, 1958 [April 3, 1957], No. 10900/58. Class 40 (3). The invention relates to a distortion correcting arrangement for start-stop code combinations in which the condition of an input circuit St1 is transferred to an output circuit St2 by means of switching elements K5, K6 which are actuated by sampling pulses occurring at the theoretical centres of received signal elements, i.e. at 10, 30, 50, &c. milliseconds in the example considered. The sampling pulses are derived from a counter Z1 responsive to high-frequency pulses from a source Tb, the pulses being applied to the counter to initiate a cycle of operation in response to the reception of a start (mark) signal which causes the triggering of a cycling switch US and the consequent closure of a gate K2. Counter Z1 also produces pulses at 20, 40, 60, &c. milliseconds which are applied to a further counter Z2 which operates after seven pulses, i.e. at 140 milliseconds at the end of a code combination comprising a start element, five permutable code elements and a stop element, to reset cycling switch US and terminate the operation until a new start signal is received. The resetting of switch US also closes a gate K3 which causes a pulse to be applied from source Tb to switches K5, K6 via a switching device D and a mixer M7. This operation ensures that the output circuit St2 is positively aligned with the condition of input circuit St1 at the termination of each code combination. In accordance with the invention, a gate K4 is included between counter Z2 and cycling switch US and is controlled by the output circuit St2 so that the resetting of switch US only takes place if the output has been set to a normal stop (space) condition for the last signal element. If a mark condition exists, gate K2 remains open, a new cycle of operation is immediately started and the output and input circuits are not positively aligned at 140 milliseconds. The arrangement according to the invention allows the apparatus to repeat a long mark switching signal, e.g. a dialling signal. In the event of such a signal which terminates in the interval between 130 and 140 milliseconds the invention prevents distortion, since, in the absence of gate K4, the positive alignment of the output circuit at 140 milliseconds would cause the signal to be reduced in duration to 130 milliseconds. Triggering of switch US by a start signal is effected by an input switch ES which is actuated by the start signal transition via a differentiation circuit Di and closes a gate circuit K1 whereby pulses from a source Ta are applied to the switch US. A pulse from the differentiating circuit is also applied to close switching device D for a period sufficiently long to prevent a pulse from source Tb passing through gate K3 (which is open until switch US is triggered) to mixer M7 and gates K5, K6. The pulses from Ta are 180 degrees out of phase with those from Tb.
