Abstract: 1,254,295. Television. FERNSEH G.m.b.H. 16 July, 1969 [27 Nov., 1968], No. 56357/68. Heading H4F. To facilitate editing magnetic tape on which is recorded a television signal, additional information, such as the tune of recording, is simultaneously recorded during the vertical blanking periods. Thus, in Fig. 1, incoming television signals 1 are mixed at 2 with signals from a camera 7 viewing a representation 8 and fed to a recorder 9 and a monitor 14. A synchronizer 3 and pulse generator 4 provide the camera 7 with horizontal sync. signals H, vertical sync. V delayed for half a field period at 6 so that video signals produced on viewing a centrally placed representation 8 occur during the vertical blanking period of signal 1, and blanking signals A which blank the output of camera 7 during the horizontal and vertical sync. pulses of signal 1. The recorder 9 provides an output at 15 for transmission purposes, at which the additional information has been blanked out again, and an unblanked output at 10 for viewing on a monitor 13 which shows the information at the picture margin. In a second embodiment, Fig. 4 (not shown), a readout unit delivers information simultaneously available at the outputs of a digital quartz clock, i.e. the time and date, as successive pulses to the mixer 2, under the action of integrated or differentiated horizontal and vertical sync. signals derived from the signal 1.

Title: Data compression methods and apparatus
IPC: H04B1/66
Filed: 1972-12-08
Abstract: 1413340 Digital transmission; coding; facsimile systems XEROX CORP 8 Dec 1972 [10 Dec 1971] 56668/72 Headings H4P and H4F An OR-gate three Fig. 2 is used to encode a multibit word for transmission and serves to reduce the amount of redundant information being sent. The word may be derived for example from an arry of photosensitive devices in a document scanner. In the embodiment a 128-bit word is divided into 4-bit groups fed to respective OR gates 111a to 111n. The outputs of these OR gates are again grouped into fours at the inputs to respective OR gates 112a to 112m; and so on until a single output AO is achieved. The transmitted signal is to consist only of the inputs to those gates which produce a 1 (black) output; all groups consisting entirely of O's being ignored. The transmitter (11-16, Fig. 1, not shown) achieves this by storing 12 all the OR gate inputs, plus the output AO, and sampling 13 the OR gate outputs sequentially starting with AO. If this is 1, then 1 is stored for transmission (15) and the inputs A1, A2 to OR gate 114 are sampled. If either is 1 (say A1) then 1, 0 (= A1, A2) is stored (at 15) for transmission, and the inputs A11-A14 of OR gate 113a are sampled. This continues until all gates have had their outputs sampled, and those producing 1's have had their imputs sorted at 15. Transmission may be effected in serial or paralle read-out (from 15) using optional modem and/or multiplex techniques. The receiver (21-26, Fig. 1, not shown) effectively re-inserts the missing all-O groups. The received signal is sampled in groups (at 24): if a 1 is sensed a transfer unit (22) feeds in to group store (23) the next group of received digits which represent the inputs to the OR gate whose 1-output has first been detected (at 24); if a O is detected, however, an appropriate group of O's is fed into the store (23) by the unit (22) from the shift control (25). Details of the transmit-receive circuits of Fig. 1 are described (Figs. 4, 5, not shown).

Filed: 1978-12-13
Abstract: A flow passage L within an exhaust gas manifold C which, in use, is at substantially constant pressure serves to guide exhaust gases from the cylinders of an engine to a turbine. The passage L communicates with the buffer space formed between the passage wall and the outer wall of the manifold. At each exhaust gas impulse, a fraction of the exhaust gases is permitted to pass into the buffer space. The exhaust gas impulses are thus prevented from giving rise to increases in pressure within the passage L whilst the kinetic energy of the impulses remains approximately the same. The buffer space may communicate with the passage L through openings (O), Figs. 3 to 6 (not shown), in a passage defining a wall or walls. <IMAGE>
