Filed: 1922-12-28
Abstract: 212,674. Forbes, Sir C. S. Dec. 28, 1922. Colour photography; films.-A roll film spool or cartridge comprises a front film sensitized mainly for one particular colour (e.g. green), and a rear separable opaque strip sensitized mainly for another colour (e.g. red). The rear strip may be the ordinary backing strip of a roll film. Ordinary prints may be obtained from the front film discarding the second image, or for colour work a filter may be used filtering out ultra-violet rays and the two colour records used to obtain colour prints by any known process. The rear film may be developed as a positive. Specifications 5641/08, 873/15, and 14511/15 are referred to.

Title: Improvements in a process for the preparation of crustless cheese
Inventor: DUBBERS HANS
IPC: A23C19/082
Filed: 1937-06-04
Abstract: A melting salt for use in making crustless cheese consists of a fusion mixture of alkali metal orthophosphates with magnesium salts or magnesium oxide, said fusion mixture being free from water of constitution.  In an example, sodium dihydrogen orthophosphate and sodium monohydrogen orthophosphate are heated to about 700-900 DEG C. with magnesium oxide or carbonate to the point of quiescent fusion.ALSO:The process described in the parent Specification for the manufacture of crustless cheese is modified by using as the melting salt a fusion mixture of alkali metal phosphate with magnesium salts or magnesium oxide, said fusion mixture being free from water of constitution.  Known melting salts may also be added.  In an example, the melting salt is prepared by heating sodium dihydrogen orthophosphate and sodium monohydrogen orthophosphate to about 700-900 DEG  C. with magnesium oxide or carbonate, to the point of quiescent fusion.  If a salt richer in alkali is desired, more of the sodium monohydrogen orthophosphate may be included in the melt or other phosphates, e.g. tetrasodium pyrophosphate may be added to the fusion mixture.

Filed: 1920-12-16
Abstract: 175,833. Metall - Industrie und Handels Ges., and Ilseman, F. Dec. 16, 1920. Jacks.-In fluid-pressure jacks the piston i is mounted on a tubular stem k which is slidably but non-rotatably mounted in a cylinder c and is threaded internally. The stem k is prevented from rotating by the engagement of a boss l with .a rod m of square cross-section fixed to the bottom of the cylinder. The end q of the handle r is threaded to engage with the stem k and is formed with a conical recess s to receive the conical end t of the rod m.

Title: Improvements in or relating to valve controlling means for internal-combustion engines
IPC: F02D1/00
Filed: 1935-12-21
Abstract: 468,360. Valve gear. AMERY, G. Dec. 21, 1935, Nos. 35438/35 and 4292/36. [Class 7 (vi)] In an engine having fuel-injection valves provided with opening-pistons and closing- pistons, fluid pressure is supplied to the pistons of the several valves by a distribution unit, so that when the pressure is relieved from the closing-piston the valve is opened, and when the pressure is applied to the closing-piston the valve is closed against the action of the fuel pressure thereon. Fig. 3 shows the invention applied to the actuation of the fuel-injection valves 15 of an engine, which are opened by the fuel pressure in pipes 13, 14 acting on shoulders 19 on the valves, when fluid pressure acting on pistons 20 at the top of the valves is cut off by a distribution unit 25. This fluid acting on the pistons 20 may be the fuel supplied by a pump 11 to the pipes 13, 14, and is conveyed by a pipe 26 to an annular pipe 36 surrounding the distributer and having branches 37 leading to valve chambers 32, 33, 34, &c. which have pipe connections 21, 31, 41, 51 to the various injection valves. Each of the chambers 32, 33, 34, &c. is fitted with a piston valve 43, Fig. 1, contacting with a central cam 53. When a valve 43 is in the position shown at the top of Fig. 1, fluid is supplied to the piston 20 of the corresponding injection valve, to maintain it closed; but when the valve is actuated by the cam, as shown at the bottom of Fig. 1, the fluid is released through passages 143, 59, 60, and the corresponding injection valve is opened. The cam 53 is tapered at 58, so that the duration of fuel injection can be varied by sliding the cam axially. The time of injection is advanced or retarded by axial adjustment of a helical gear 56 which drives the cam. According to the first Provisional Specification the invention may be applied to ordinary inlet and exhaust valves. Specifications 353,621 and 442,532 are referred to.

Abstract: 1,262,447. Frequency discriminators. HONEYWELL Inc. 23 July, 1970, No. 35651/70. Heading H3A. [Also in Division G4] A frequency discriminator comprises: a signal source 11 having a frequency which is high compared with the maximum frequency of a frequency modulated signal to be detected; means 12 for counting the high frequency signals to provide a count signal representative of the time period of a cycle of the frequency modulated input; and means 14 for operating on the count to provide an output having a linear relation to the frequency of the modulated signal. At a predetermined point in a cycle of the modulated signal, a gate in control unit 13 is opened to feed pulses from clock source 11 to a counter in unit 13. At a count of 202, the gate closes and another gate opens to feed the clock pulses to a counter 12 which commences counting with a count of 202. At the corresponding predetermined point in the next cycle of the modulated signal unit 14 divides a constant by the count attained in unit 12 to produce a signal proportional to frequency, and subtracts from this signal a further constant dependent on the mean frequency of the modulated signal to produce a signal proportional to the frequency deviation. A serial digital output is directly obtainable from unit 14, a parallel digital output is obtainable via a hold register 16, and an analogue output is obtained from a D/A converter 17 fed with the hold register output. Details of the units 13, 14 are given, Figs. 2, 3 (not shown).

Abstract: 1308207 Controlling friction clutches L SCHULER GmbH 24 July 1970 [24 July 1969] 35990/70 Headings F2F and F2L  A friction clutch for a press is engaged by a compressed air servo 1, 35, Fig. 1, against compression springs 36, the compressed air being delivered from a reservoir 30 via a manual valve 31 and a check valve 14 in parallel with a choke 12, and the check valve being closed by actuating means, e.g. an electromagnet controlled by an electric switch 39 actuated by a rod 37 fast with the piston 35 to close the switch 39 and valve 14 to restrict the flow of compressed air to the clutch-apply servo and hence cushion engagement of the clutch. When the clutch is fully engaged, the valve 14 is again opened. As shown in Fig. 2, the switch body 40 is mounted on a slide 58 itself mounted by a friction ratchet 56 on a bolt 41 fast with the cylinder 1. The slide is self-adjusting for clutch wear so that the switch actuating member 38 is always depressed a predetermined distance K by rod 37 on engaging the clutch. The piston 35 carries bolts 55 on which are mounted the compression springs 36. The piston acts on a thrust plate 47 to urge a driven plate 50 against a flywheel 54. Again, as shown in dash-dot lines on Fig. 2, the rod 37 and switch are replaced by a rod 60 on the thrust plate 47 and a switch 61 on the piston 35, or vice versa. A compression spring 63 urges the piston and plate 47 apart to take-up the play between the piston and a ring 48 fast with the plate 47. Again, Figs. 3 and 4 (not shown), in a spring-applied, compressed-air released friction brake, cushioned engagement of the brake is provided by situating the choke (74) and the piston-controlled check valve (77) in the air exhaust line.

[Also in Groups XL (a) and XL (b)] In an electronic scanning system employing a pick-up tube of the kind utilizing the variation in resistivity with applied radiation of a mosaic of semi-conductor material, a rectangular-waveform generator is synchronized with a tube beam deflection signal generator so as to interrupt the beam current periodically in such a manner that following each scanning of any part of an image with the beam current uninterrupted, at least the next time that the deflection signal corresponds to that part of the image, the beam current is interrupted. Blurring of moving objects on reconstituted images, due to persistence of the effect of radiation on the mosaic, is thus avoided. The beam interruption may be synchronized with either line or frame deflection. Beam intensity during scanning may be controlled to vary inversely as the recurrence factor of the periods of uninterrupted beam current.
