Title: Improvements in telephone systems
IPC: H04M3/32
Filed: 1925-03-17
Abstract: 256,659. Standard Telephones &. Cables, Ltd., (formerly Western Electric Co., Ltd.), and Baker, J. H. E. March 17, 1925. Selective signalling apparatus for indicating the receipt of a number of trains of impulses consists of two banks of ten lamps and two step-bystep switches SO, ST which are stepped round to light particular lamps by the received impulses, the first impulse train operating the switch SO, the second the switch ST, the third the switch SO, and so on. To make a preliminary test of the lamp banks a key LK is thrown each way in turn and the digit 9 dialled on the slow dial SD to operate the stepping magnet R1 or R2 of the switch SO or ST and light the lamps in turn. When the key LK is released, the restoring magnet RL1 or RL2 is energized over a restoring wiper and a relay K which lights a signal lamp RSL. The incoming impulses are received by the relay A which repeats the first digit to the magnet RI, which steps the switch SO to a corresponding lamp. Relay C energizes in series with magnet RI, closes a circuit for relay D, and energizes relay N over its half-step upper winding. At the end of the impulse series, relays C, D relapse, and the relay N fully energizes over both its windings in series and switches the impulse circuit to the magnet R2 of the second switch ST, which records the next digit. During this digit relay C closes a halfstep circuit for relay M and when the relay C relapses on the cessation of this digit, the relay M energizes fully over contacts of relay D, releases relay N and closes a circuit for the release magnet RL1 of the first switch SO in series with relay E, which lights the signal lamp RSL. The relapse of relay D de-energizes the relay M and the third digit is sent to the switch SO. At the end of this digit, the relapse of the relay D closes a restoring, circuit for the switch ST. This cycle continues, the received digits being alternately recorded on the two switches. When all the digits have been transmitted, ground is removed from the private wire and causes the relapse of all the operated relays P, A, H, and B. Reference has been directed by the Comptroller to Specification 241,521.

Title: Automatic measuring lead screw compensator
IPC: B23Q11/00
Filed: 1966-02-22
Abstract: 1,133,229. Compensating for temperature fluctuations in machine tools. PRATT & WHITNEY Inc. 22 Feb., 1966 [23 Feb., 1965], No. 7614/66. Heading B3B. [Also in Division G3] Pneumatic or electrical means are used to measure the thermal expansion of a feed screw of a machine tool carriage or table and to compensate therefor by applying suitable rotation to the feed nut associated with the carriage. In a first embodiment the thermal expansion of a feed screw 28 is measured by means of an air pressure nozzle 45 positioned adjacent -the free end of the screw, any rise in pressure being employed to adjust the position of a pivoted linear cam 48 which through a follower 47 and lever arm 46 attached to the feed nut 35 imparts compensating rotation thereto. Compensating movement of the linear cam 28 causes a fall in pressure at a second air nozzle 51 positioned adjacent a part of the cam, the two nozzles being connected to a common amplifier, Fig. 6, so that a null or balanced pressure point is reached when compensating movement is is complete. A reversible motor 50 is arranged to raise or lower the cam in accordance with the pressure signals. The cam is pivoted adjacent the fixed end of the feed screw and extends generally parallel thereto. The cam surface is preferably ground to compensate for any manufacturing errors in the screw. The system is described as applied to two feed screws (Fig. 1, not shown), one for the carriage of a boring or drilling machine and the other for a table mounted thereon. In a second embodiment (Fig. 7, not shown), thermal expansion of the feed screw (28) adjusts the position of a movable core (153) associated with a first transformer (150); the latter has two windings (151, 152) connected in a bridge circuit with a second similar transformer, (155) having a core (198) movable with the cam member (48). Electrical imbalance in the circuit is caused by expansion of the feed screw and is utilized to operate a motor (163) which adjusts the position of the cam till electrical balance is restored and the thermal expansion of the screw compensated for.

Title: Method of producing pressed yeast
IPC: C12N1/18
Filed: 1948-03-12
Abstract: Pressed yeast is obtained from molasses by a modification of the aeration process in that the propagation is carried out in several stages using in all, or at least some of said stages a mixture of molasses and a de-yeasted or de-alcoholized wort as propagating medium.  In an example pitching yeast is obtained in a four stage process in which 200, 800, 3,500 and 6,000 kgs. of fresh molasses are successively utilized, at each of these stages de-yeasted wort or thin or thick residual liquid is added.  The pitching yeast may then be utilized in 16 commercial yeast fermentations in each of which 2,000 kgs of molasses and 130-150 hectolitres of de-yeasted wort is utilized.  The de-yeasted wort should be heated to 85 DEG C before use.  Generally the yeast shows no sign of exhaustion but should this occur then an intermediate fermentation making use of molasses alone should be effected.

Abstract: 577,672. Dirigible radiant beam systems. HAZELTINE CORPORATION. June 6, 1942, No. 7752. Convention date, May 26, 1941. Drawings to Specification. [Class 40 (v)] A radiant-signal system having a sharplydirective characteristic which is variable in direction with frequency comprises a number of radiant-signal " translators ", (e.g. dipole antennae), physically spaced in one direction by pre-determined wave-length valves, a wavesignal translating circuit, and wave-delay devices coupling this circuit to the translators and providing between each pair of adjacent translators an electrical spacing of a higher order of magnitude (say 5 to 50 times) than that of the physical spacing, thereby giving the system a sharply-directive characteristic the direction of which varies with the wave-length. The form of the invention described is that illustrated in Figure 1 of the drawings of Specification 577,674, and described in the abridgment of that Specification. Assuming that the dipole " translators " are spaced from one another by half a wavelength at the mean operating frequency of 100 megacycles, and that the delay networks introduce a delay of ten periods between adjacent dipoles at this frequency, then a frequency variation of Œ5 megacycles will cause the direction of the beam to change by 180 degrees.

Filed: 1927-03-21
Abstract: 292,669. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). March 21, 1927. Materials and compositions for purifying.-In separating sulphuretted hydrogen and ammonia from coke oven and illuminating gases by absorp. tion in solutions of oxygen compounds of sulphur, such as polythionates, thiosulphates containing sulphur dioxide, and sulphite-bisulphate solutions, a part of the ammonia is first separated as an aqueous condensate on cooling the gas for example, and is added in the later stages of the washing operations. Ammonia from a separate source may be used if the gas does not already contain it. The first stages of the washing are carried out with solutions of ammonium polythionates or of thiosulphate with addition of sulphur dioxide to the gas or the washing liquid, and the second stages with ammonium polythionates to which the separated ammonia has been added or with ammonium sulphite-bisulphite solutions obtained from the separated ammonia and from sulphur dioxide obtained from the sulphur obtained by the decomposition of the thiosulphates. The solutions of thionates or thiosulphate obtained from the second washing stages are used in the first stages. Pressures of 5-15 atmospheres may be used particularly in the later stages. Sulphuretted hydrogen and ammonia may also be separated from gases by treatment with water under pressure. The solution obtained, before or after releasing the pressure may be treated with the washing liquids, or the pressure may be released to allow escape of sulphuretted hydrogen or gas while the ammonia remains in solution. Sulphur dioxide may be added to the gas before or during the compression. The ammonium salts in the washing liquid may be replaced by salts of the alkali metals or of zinc, magnesium &c. Specification 10147/12 is referred to.

Filed: 1933-03-15
Abstract: 416,723. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and BROWNE, C. O., 29, Monk's Drive, West Acton, London. March 15, 1933, No. 7896. [Class 40 (iii).] A synchronizing signal is produced before the scanning of each line of a film 1, which moves to give one component of the scanning, solely by the motion of the scanning-element 5 corresponding to that line or by means of a corresponding special synchronizing element which duplicates any error in the position of that scanning element. The synchronizing signal is produced by the mirror 5 sweeping over an aperture 16 an image of that part 15 of an illuminated slot which is not covered by a rotating disc 14. If there is delay in the synchronizing transmission circuit, the signal is produced while the previous line 11 is being scanned ; otherwise it is produced between the scanning of successive lines. A long frame synchronizing signal is generated between successive complete images by the uncovering of the whole of the slot 12 by a notch in the edge of the disc 14 which is geared to the drive of the film. The illumination of the film is interrupted during the production of the synchronizing signal by an arm on the disc 14. The synchronizing signals control 'the duration of oscillations from an independent generator of sub-carrier frequency, which are transmitted on a single high-frequency carrier, Fig. 7 (not shown). When an apertured scanning disc is used, a special set of holes generates the line synchronizing signals, and each scanning hole and its corresponding synchronizing hole are formed by two punches rigidly connected together with their axes in fixed positions relative to the axis of the disc. Specification 398,228 is referred to.
