Abstract: 1,124,876. Data transmission systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Feb., 1967 [26 Feb., 1966], No. 8625/67. Heading H4P. In a data transmission system, to reduce the number of errors passed to the receiver output, each bit is transmitted three times, the receiver including a majority decision unit and means to pass to the receiver output either the output of the decision unit or one bit of each of the groups of three bits. Source 1 supplies data to channels C1, C2, C3, there being unequal delays 5 and 6 as shown. The channels are time-division multiplexed at 7 and pass to a demultiplexer 11 at the receiver. Delays 12, 13 remove the time differences between the pulses in the three channels. The channels feed majority decision unit 14. Units 23, 24 compare the bits in the channels and control a unit 20 which controls switch 16. If, after aperiod equal to the delay of delay 12 in which there has been no error, unit 23 detects an error, unit 20 sets switch 16 to receive pulses from channel C1 for a duration equal to that of delay 12, after which the switch resets to the position shown, and is held in that position for a duration equal to that of delay 12. If an error is detected by unit 24 when the switch is as shown the switch is held in that position for a duration equal to that of delay 12.

Filed: 1917-06-16
Abstract: 111,059. Warmer, A., and Owen, A. E., (trading as Owen & Co., R.). June 16, 1917. Tapping.-In a releasable-tap machine for tapping nuts &c., the tap is replaced by hand. The tap-holder C is carried by a driven spindle which is raised and lowered by rack-and-pinion gear actuated by a sprocket wheel J over which passes a chain carrying a weight at one end and secured to a treadle at the other. The top is held in the chuck by hand until it has entered the work. When it has passed through the work it falls out of the chuck and is replaced by hand. When the treadle is depressed to raise the spindle a camplate L co-acts with a roller M to swing a lever W carrying a pawl N by which the work table E is rotated to bring another nut under the spindle. At the same time a second cam-plate P withdraws a spring-pressed locking lever Q from the notch O<1>, O<2> &c. with which it was engaged. The pawl N rotates the table by means of these notches. When a finished nut is brought over a recess R in the bed of the machine, an ejector S operated by the chain removes it and it falls down a shoot into a receptacle below.

Patent GB-739728-A (GB)
Title: Improvements in or relating to method of producing a culture medium for propagating hog cholera virus, the culture medium resulting from said process and a hog chlorera vaccine
IPC: A61K39/187
Filed: 1953-03-31
Abstract: A hog cholera vaccine is prepared by subjecting virulent hog cholera virus to serial culture containing living pig tissue for at least 15 serial passages until said hog cholera virus acquires a reduced virulence that will no longer produce pathological symptoms when injected into a normal pig but retains self-propagating characteristics and gives rise to the production of protective antibodies.  Hog serum is ultrafiltered to remove hog cholera immune fractions, diluted with a physiological solution, sterilised, a small quantity of comminuted living reticuloendothelial tissue of a pig susceptible to hog cholera added, the pH adjusted to 7.4 to 7.5 and the medium so formed inoculated with virulent hog cholera virus which is incubated at 37 DEG  C. for three days and at room temperature for one day.  A cysteine salt, e.g. the hydrochloride and a small amount of pig spleen hydrolysate or p-aminobenzoic acid may also be present in the culture medium.  The virus is serially propagated through similar media until the desired attenuation has been obtained. The modified virus is then mixed with an equal volume of a diluent such as sterile skim milk, placed in the final market container and is quick frozen and dried, the containers being stoppered, evacuated and sealed.  Specification 627,584 is referred to.
Patent GB-551317-A (GB)
Title: Improvements in or relating to high pressure hydraulic systems
IPC: F15B1/027
Filed: 1941-07-14
Abstract: 551,317. Hydraulic apparatus. RUBERY OWEN MESSIER, Ltd., and PERRICHES, A. A. July 14, 1941, No. 8907. [Class 69 (ii)] In an apparatus for supplying hydraulic power systems with liquid under pressure which comprises a supply pump 11, delivery pipe 17 and a non-return valve 12 connected to an accumulator 15 and the supply pipe 13, improved means are provided for by-passing the liquid to tank 18 when the supply liquid reaches a predetermined pressure, the by-pass pipe 16 being arranged between the pump 11 and valve 12 and being controlled by a valve 20 supplied with operating fluid by a control valve 26 which is similar in construction to the valve described in Specification 515,804. The valve 20 is normally closed by a spring and is opened by a piston 22, its construction being similar to a valve described in Specification 425,207, and the valve 20 is opened by means of pressure fluid supplied by a pipe 24 when the valve 26 opens upon the pressure in pipe 13 reaching a value such that pressure on the valve face 38 overcomes the action of a spring 28. As soon as pressure acts upon the piston 33 to which the valve face 38 is attached the valve 26 opens quickly and fluid passes to valve 20 which is opened by the raising of piston 22. The motion of piston 33 to the left closes a valve 31 and cuts off an outlet 30 to the tank 18. Pressure then becomes equalized on both sides of the piston 33 through passage of fluid through a leak passage 35 and the pressure acting upon the valve 29 maintains the valve 26 open against the action of spring 28 until at a predetermined low pressure the spring 28 closes the valve 26 and the valve 20 then closes under spring action as pressure is cut off from the piston 22 owing to the opening of valve 31. A restriction 19 is arranged in the by-pass which permits passage of only sufficient liquid to keep the pump lubricated. Specifications 461,453 and 501,100 also are referred to.

Title: Method and apparatus for the production of random signal sequences
IPC: G06F7/58
Filed: 1953-03-31
Abstract: 750,090. Code telegraphy. LORENZ AKT.- GES., C. March 31, 1953 [April 2, 1952], No. 8944/53. Class 40 (3). In an arrangement for producing random sequencies of signal elements which are one or the other of two kinds and a number of which are combined to form a signal, such as a fiveunit teleprinter signal, pulses from an oscillator circuit having a frequency determined by factors which may be subject to random variation are applied. Bistable trigger arrangement, the final state of which depends on the number of applied pulses, corresponds to a signal element of one of the two kinds. The oscillator may be operated a number of times in sequence to produce the elements of a signal, or a number of oscillators with associated triggers corresponding to the number of signal elements may be operated simultaneously. In the circuit shown, the operation of a key Ta effects the charging of capacitor CL1 from a voltage source Ust. Subsequently, capacitor CL2 charges, causing the valve I to strike, effecting the discharge of the capacitor CL2 and the production of impulses whilst the key is held down and subsequently until the capacitor CL1 is discharged. The pulses, amplified by the valve II, are fed simultaneously to the grids of valves III, IV of a bistable trigger arrangement 2, each pulse reversing the trigger by rendering non-conductive the valve which is conducting. A relay R having windings in the anode circuits of the valves is operated to a final position dependent on the number of pulses (odd or even) derived from the oscillator. The groups of signal elements may be recorded on a perforated tape employed to cipher a coded message or may be employed to modify the elements of a signal to produce the ciphered version. The signals produced by the arrangement may be utilised to provide sequences of random values for statistical analysis.

Title: Method and device for generating a signal dependent on and indicative of the distance of an object from the generator of said signal
IPC: G01B11/00
Filed: 1976-03-05
Abstract: 1536496 Optical position finding W WITTE 5 March 1976 [19 March 1975 27 Sept 1975] 08948/76 Heading H4D The detection of a target within a predetermined space is performed by apparatus which is arranged to project the image of a pattern into the target space along with an inverted image of the same pattern (reflected by means of a mirror extending parallel to the optical axis of the apparatus). The pattern, of checkerboard nature (see Fig. 6, not shown), is arranged to be moved such that its pattern changes cyclically. Hence if an object exists within the target space, the light reflected from the pattern imaged on same, will have an alternating component due to the interaction of the upright and inverted patterns and this may be detected by an optical system which images the target space on a photocell connected to, e.g., a loud-speaker. The pattern is also arranged to cyclically occupy a range of positions along the optical axis during a pattern cycle whereby a given depth of field may be scanned with the pattern image thereby realizing the target space within which an object will be detected.
Patent GB-349201-A (GB)
Title: Process for the manufacture of yeast of high enzymatic activity
IPC: C12N1/22
Filed: 1930-03-20
Abstract: Yeast of high enzymatic activity is prepared from yeast multiplied in any known process by a further development in two working stages in such a manner that in the first stage, by assimilation, nitrogenous substances complete the plasm of the yeast cells with simultaneous inhibition of multiplication and in the second stage, by setting up a strong fermentation, the enzymes of the cells are caused to develop. In the first stage the yeast is transferred to a fresh mash and nitrogenous substances and small quantities of fermentable carbohydrates are added and the aeration is strongly reduced, or suitable additions may be made to the original mash.  If organic nitrogen compounds are used these are preferably opened up by biological processes (by lactic acid bacteria or yeast autolysis) or by means of oxyacids under pressure.  In the second stage the amount of fermentable carbohydrates in the mash is increased to about 6 per cent after acidulation of the mash, preferably by fermentation.  In an example, there is added to a mash after completion of multiplication of the yeast a yeast extract opened up by lactic acid fermentation combined with autolysis and also molasses or malt extract, so that the assimilable nitrogen amounts to 0,12 per cent and the sugar 1 per cent.  After some hours thick molasses or malt extract is added and the mash strongly fermented. Another example is given using a fresh mash for the first stage and an example using inorganic nitrogen compounds. Specifications 264,795 and 277,476, [both in Class 14 (ii), Beverages &c.], are referred to.
