Title: Method and apparatus for evaluating coded binary signals
IPC: H04L1/00
Filed: 1971-04-27
Abstract: 1342505 Data transmission; error detecting LICENTIA PATENT - VERWALTUNGS. GmbH 27 April 1971 [27 April 1970 22 Oct 1970] 11656/71 Heading H4P In an error detecting data transmission system, particularly for video data, where the same signal can be repeated, the receiver checks for parity a first and a second signal transmission and replaces the first by the second if the second is parity error free and also compares the two transmissions and gives an indication if they are not identical. A third transmission may replace the preferred one of the first or second if it is parity error free and there is also lack of identity between the first and second. In Fig. 1, during a first transmission, counter 12 set to 1, data received in register 7 is subject to a parity check by device 8. By means of writing in signal Ts, AND gate 11 opens gate 9 to read in to register 5 a received signal (A-G) and the result of the parity check (P). The register 5 and delay line 4 form the memory circuit of a CRT display S. The signal received in register 7, during the second transmission is compared with the first signal by device 15 and checked for parity by device 8. The writing signal Ts only reads into register 7 the second transmission if gate 13 is open as a result of no parity errors, otherwise the first transmission remains and only the result of the identity check (1,0) is written into register 7 at position N. The signal from a third transmission (counter set at 3) is only written in if it is parity error free and there is no lack of identity signal in position N, thereby allowing gate 17 to open and open gate 9. In a modification of Fig. 1 (Fig. 2, not shown) longitudinal block parity is also checked and the transmission of the second and third signals is optionally automatically or operator controlled.

Title: Improvements in starting apparatus for internal combustion engines
IPC: B07B1/42
Filed: 1937-04-24
Abstract: 481,468. Thermal switches. BOSCH AKT.-GES., R. April 24, 1937. No. 11767. Convention date, May 8, 1936. [Class 38 (v)] [Also in Group XXXV] In starting and fuel-vaporizing systems for internal-combustion engines in which the electric starting circuit is rendered operative in response to a certain heating effect on the fuel, one terminal of a thermostatic switching member engages a frictionally held contact permitting further expansion of the thermostat after contact permitting further expansion of the thermostat after contact has been made, yet allowing of immediate separation. The bifurcated bi-metallic member 31 is mounted by two pedestals 26, 27 on a base 25 which also carries a conductive strip 40 and a support 35 for a rocking member 30 pivoted frictionally at 36. When spring contact 41 is pressed as by a button, into contact with strip 40, current is supplied from the battery along lead 15, bimetallic member 31. and lead 17 to the fuel heater. As member 31 heats and bends, it finally engages contact 34 and completes a circuit to the starter along lead 23. Further bending of member 31, pushes contact 34 before it, the rocking member 30 moving on its frictional pivot 36. As soon as member 31 starts to return, it is disengaged from contact 34 and, after further movement, engages an insulated adjustable stop 39 on the rocking member 30. In a modification, the rocking member is held frictionally on the end of the bi-metallic strip. The bi-metaltic strip may itself heat the fuel pipe or a separate heating resistance may be provided, the strip not then being used as the current conductor. If compressed air is used for starting, a valve replaces the contact device.

Abstract: 929,779. Prepayment meters. SANGAMO WESTON Ltd. March 30, 1960 [April 7, 1959], No. 11769/59. Class 27. [Also in Group XXIV] A credit and arrears registering device for coin-freed apparatus, such as an electricity meter, comprises two discs 10, 15 which have notches 12, 17 and are driven at slightly different speeds in the same direction from a spindle 20 connected, for example to the planet wheel of a credit and measuring-out differential, the notches being in line when the credit/arrears condition is zero so that a feeler pin 21 on a switch arm 22 enters the notches and closes an associated switch; as the discs rotate in either direction to establish credit or arrears, the switch is closed or moved to a position where it can be closed by means such as a press-button, and the notches are out of alignment after the first revolution and do not come into alignment again until after a number of revolutions. The discs are connected to gears 11, 16 having teeth which are of the same general dimensions but are slightly different and both gears mesh with a gear 19 on the shaft 20. The disc 10 is fast on a shaft 13 connected to a pointer 14 and the disc 18 is rotatable on the shaft 13 and held by a collar 25 which can be moved axially to allow adjustment of the meshing of the gears 11, 16 and 19; In alternative constructions, the input drive is made direct to the spindle 13 and the pinion 19 acts as an idler gear between the gears 11 and 16, or the pinion 19 is made in two halves interconnected by dog teeth so that they can be separated for adjustment of the slot alignment. The lever 22 may operate the switch directly or through a shaft 23. The stress in the spring 24 when the lever is deflected may be used to operate the switch itself or, preferably, a latch lever which allows the switch to trip.

Filed: 1974-03-18
Abstract: 1442281 Fibril-bearing filaments HOECHST AG 18 March 1974 [17 March 1973] 11870/74 Heading B5B [Also in Divisions D1-D2] In a process to manufacture filament yarn having protruding filament ends from melt spun filaments heat melt-spun filaments are subjected to a cooling process along certain sections of their length only to give sections of differing drawability, the filaments subsequently being drawn by an amount lying between the drawability of the respective sections and hence fracturing the filaments. An apparatus for carrying out this process comprises means 4 for conveying a plurality of filaments 1 and a rotatable roller 3 having one or more recesses or spiral grooves which produce a staggering of the filament breaks. The sectional cooling may alternatively be by means of cold gas jets. The cooling roller 3 should be arranged within one metre of the solidification point of the filaments emulating from the spinneret 2. The yarn produced can contain additional filaments of uniform drawability, e.g. by bypassing the roller 3, to give a stronger product. The protruding ends may be temporarily integrated, e.g. by sizing, twisting or interlacing with gas jets for further processing. An example is given employing 64 polyethylene terephthalate filaments and temperature and apparatus dimensions are given. Reference is made to Specifications Nos. 924,086 and 777,625.
