Title: Improvements in or relating to data transmission
IPC: H04L1/18
Filed: 1966-03-22
Abstract: 1,096,450. Data transmission systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 22, 1966 [March 26, 1965], No. 12684/66. Heading H4P. In a system in which errors in transmitted digital data are corrected by repetition a first signal is passed from the receiver to the transmitter upon detection of an error. This causes the transmitter store to be reversed and a second signal to be sent to the receiver. When the start of this second signal arrives the first signal ceases. At the transmitter this causes the second signal to cease and the store to be reversed to normal, repetition then taking place. The receiver store is inhibited for the duration of the second signal. A clock train at bit rate accompanies the data signal, which is continuous. An error checking circuit, Fig. 2 (not shown), makes odd/even counts of the clock pulses arriving during the first and second signals. If these differ, transmission is stopped or the receiver store marked. A circuit using a single counter is described, Fig. 3 (not shown).

Title: Improvements relating to locks
Inventor: MCDONNELL VINCENT CLEMENT
IPC: E05B55/00
Filed: 1954-05-04
Abstract: 761,691. Locks. REMPLOY, Ltd. May 4, 1955 [May 4, 1954], No. 12986/54. 'Class 44. Relates to a lock in which a spring-loaded bolt is controlled by co-operation between a pin and a cam track so that after alternate movements of sufficient extent into the lock case, the bolt can be moved by the spring to a partially shot and to a fully shot position, the pin being carried by the look case and the track being carried by the bolt or vice-versa, and the pin being movable relative to the member carrying it, in a direction substantially at right-angles to the direction of movement of the bolt. According to the invention the track consists of four limbs and four stations each at the junction of two limbs, the limbs being so shaped that in travelling round the track, the pin reaches each station by part of a limb inclined to the direction of movement of the bolt, and on reversal of movement of the bolt, leaves each station by part of a limb lying substantially parallel to the direction of movement of the bolt, and the movement of the pin is subject to frictional resistance sufficient to assist the pin in entering the correct limb on leaving each station. As shown, a latch bolt 8 which is operable by a key-operated lock on one side of a door and by a knob on the other side, is movable by means of a crank 32 fixed to a hub 33 coaxial with a hub 24 of the knob and carrying a pin 34 which engages a slot 36 on a lug 38 on the bolt. The pin 34 is loaded by a spring 40 and the slot 36 is curved such that the pin deadlocks the bolt in the fully shot position thereof. A lost motion connection 42 between the hub 24 and the hub 33 and a further lost motion connection 44 between the hub 33 and a tongue 22 permits the bolt to be retracted from a partially shot position without movement of the knob and lock, when the door is slammed. The hub 24 incorporates a cylinder lock by which to lock the knob to the lock case. The bolt is controlled by a pin 46 on a freely rotatable lever 48 and the pin-co-operates with a track 50 in the bolt face. The pin 46 is spring-loaded on to the track which is formed with four limbs providing stations 54, 56, 58 and 60 for the pin corresponding to the partially shot, the fully shot, and the fully withdrawn positions of the bolt 8. Ramps 62 on steps 64 ensure unidirectional movement of the pin round the track. The bolt may be retained in the withdrawn position by a plunger 66. Specification 641,335 is referred to.

Title: Improvements in or relating to systems for reproducing film sound records
IPC: G11B7/00
Filed: 1937-05-10
Abstract: 477,252. Optical sound-reproducing. ELECTRICAL RESEARCH PRODUCTS, Inc. May 10, 1937, No. 13265. Convention date, June 4, 1936. [Class 40 (ii)] Relates to the reproduction of sound from film records 3 of constant-width variablealignment type, i.e. having a transparent or opaque track of constant width oscillating laterally along the centre of the film as shown in Fig. 2, by means of an apparatus comprising a slit 11, Fig. 1, and an optical device 6 for separating the beam of light passing through the film 3 from a source 1 into two parts corresponding to the two halves of the film, each part affecting separate light cells 7, 8, the output of which is combined in push-pull. According to the invention, in order to reduce ground-noise, the effective amount of the light passing through the film is reduced gradually from the centre to the edges of the film or vice versa according to whether the centre track is opaque or transparent. This may be obtained by making the slit 11 narrower towards its ends as shown in Figs. 5 and 6 ; in addition, the slit may be separated into two halves as shown in Figs. 3 and 4. Alternatively, an apertured screen 18, Fig. 8, may be used between the slit 19 and a lens system 15, 16 with a stop 17, the position of the screen 18 along the axis of the system determining the gradation of the light. In a modification, a single lens is used instead of the combined lenses 15, 16 and stop 17. The aperture in the screen 18 may have one of the shapes shown in Figs. 11, 12 and 13. The same result may also be obtained by the use of grey wedges or the like.
