Title: Improvements in or relating to control devices for hydraulic equipment
IPC: F16K11/072
Filed: 1958-10-31
Abstract: 865,785. Valves. SCHLEPHERWERK NORDHAUSEN VEB. Oct. 31, 1958 [May 24, 1958], No. 34996/58. Class 135. A control device for a double-acting actuator has four control positions arranged in a single plane of movement corresponding to " raise," " hold," " free movement " and " lower " actions. In Fig. 3 the valve member 3<SP>1</SP> is in the " hold " position and pressure fluid flows from the inlet 5 through a sleeve port 7, radial ports 8 and an axial bore 9 in the valve member to the outlet 12, while flow to and from the control ports 17, 22 is obturated, Figs. 4, 5, 6. On rotation of the valve member to the " raise " position, Fig. 4, by means of the handle 4<SP>1</SP>, fluid flows from the inlet 5 through sleeve ports 60 and longitudinal grooves 13 in the valve member and sleeve ports 61 to the control port 17, while the other control port 22 is in communication with the outlet 12 through the sleeve ports 20, radial valve bores 18 and axial bore 9. Rotation of the valve member to the " lower " position reverses these connections and in the " free movement " position all of the above connections freely interconnect. The valve member is loaded by a torsion spring 62 and has detent means so that if the handle 4<SP>1</SP> is released in the " lower " position it returns to the " free movement " position and if it is released from the " lifting " position it returns to the " hold " position. An additional set of control ports 17<SP>1</SP>, 22<SP>1</SP> for further equipment may be provided in the valve housing and are brought into use and ports 17, 22 are obturated by moving the valve member axially to a second position, Fig. 2, not shown, in the housing by means of the control lever 4<SP>1</SP> when a second set of ports in the valve member (shown by the same reference numerals primed) comes into operation. A lever 28 connectible to the valve member 3<SP>1</SP> when it is in its second axial position, by a dog clutch 26, is connected to the further hydraulic equipment operated by the valve so that when the equipment reaches a preset position the valve is rotated to the " hold " position.
Patent GB-472465-A (GB)
Title: Improvements in and relating to the puffing of cereals
IPC: A23L1/18
Filed: 1935-12-17
Abstract: Cereals, having a fat content of 4,5 per cent or more such as oats, are heated directly by means of steam under pressure and of such degree of superheat that the sudden reduction of pressure required to effect puffing can be and is effected after a period insufficient to permit of appreciable modification of the fat content of the grain: this period is never more than five minutes and is generally between one and a half and two minutes.  In a specific example, oats having a moisture content of between 6 and 8 per cent are placed in a container and steam at a pressure of about 220 lb. per square inch and carrying about 150 DEG  F. of p  superheat is fed in.  In about half a minute the pressure in the container rises to line pressure, and this pressure is maintained for a period of about one minute, the steam supply then being shut off and the closure of the container opened, thus releasing the pressure and causing the oats to puff.  A suitable form of apparatus for carrying out the treatment is described in Specification 472,466.  The Specification as open to inspection under Sect. 91 comprises also the application of the process specifically to wheat, maize, rye, barley and rice.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in brakes for vehicle wheels and other rotary elements
IPC: F16D55/00
Filed: 1930-11-20
Abstract: 373,592. Disc brakes. GASS, E., 28, Rue Villeneuve, Clichy, France. Nov. 20, 1930, No. 35041. Convention date, Nov. 20, 1929. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] A disc brake for vehicle wheels comprises a flexible disc 8 secured to the wheel 16 and arranged between two fixed plates 10, 4. The plate 10 is fixed on the vehicle axle by a support 12 on which the disc 4 is mounted by a flexible part 103. The support 12 carries a series of hydraulic cylinders around its periphery the pistons 87 of which are adapted to press the plates 4, 8 against the plate 10. The cylinders are mutually connected by conduits 82 and are supplied through the inlet by a main pipe 90. The brake is operated by a high-pressure piston 38, Fig. 4, depressed by a foot-pedal 35. When wear in the brake occurs the piston 54 is released to the extent required to compensate for the wear by means of the screw 59 which allows the sheave 53 attached to the low-pressure piston 54 to engage a slope 52 on the piston 38. When the brake is applied the slope 52 operates the piston 54 and drives fluid through pipe 44 to the brake conduit until the sheave reaches the top of the slope 52 when the application is continued by the highpressure piston 38. Fluid is supplied from tank 58 through a port 51. In a modified form when wear has occurred the piston 37, Fig. 6, is rotated by loosening the guide-pin 47 to close a port 50 by means of a slope 39 by the amount required to compensate for wear. On brake application the fluid which cylinder 46 contains as it is prevented from returning to the tank 58 through the port 50 is drawn by the piston 37 through valve 45 to the highpressure cylinder 40 until the port 50 is uncovered, when the piston 38 continues moving to produce the high pressure. A safety device to prevent leakage in case of a pipe breaking, comprises a piston 91, Fig. 13, having ports 98, 99 supplying conduits 100, 101. If one pipe breaks the pressure falls therein and the piston moves so as to close this pipe from the supply pipe 95. To prevent excessive braking on a lightly-loaded vehicle a device, Fig. 10, is used in which the pressure of a spring 63 may be released thus allowing a piston 61 to close the supply through the port 65 at a certain pressure.

Title: Packaging foils
IPC: B65D65/42
Filed: 1976-08-24
Abstract: Sheet consisting of aluminium or of an aluminium alloy for wrapping goods which contain fat, and process for the production thereof. With conventional sheets, there are often processing difficulties if, before the individual portions are packed or wrapped, sheet sections are separated off from their roll arranged in a packaging machine. Such sheet sections then no longer lie flat in the feed channels and, as a result, they cause operation to be disrupted. These disadvantages are eliminated by a sheet which is provided on both sides with a coating (3, 4) and in which at least the coating layer (4), intended to come into contact with the fat-containing goods to be packed, is provided with longitudinal ribs (6) which form grooves (5) therebetween. A sheet of this type is produced with the aid of a process in which the sheet body (2) is provided at least on one of its principal surfaces with a coating layer (4) and, on this priming coating layer, a top layer (7) is applied, grooves (5) being formed at the same time. <IMAGE>

Title: Improvements in or relating to apparatus for Measuring the Twist of a Helically Stranded Cord
IPC: D07B7/02
Filed: 1966-08-09
Abstract: 1,161,557. Measuring the twist of a helically stranded cord. ALGEMENE KUNSTZIJDE UNIE N.V. 9 Aug., 1966 [13 Aug., 1965], No. 35671/66. Heading G4H. The twist in a moving length of helically stranded cord is determined by passing the cord 1, Fig. 1, around a disc 2 and using a counting device to count the cord humps that pass a counting station whilst the disc 2 rotates through a predetermined angle. The counting device may be a photo-cell 8, Fig. 3, receiving light from a source 16 via a mirror 17 and a stop 18. In Fig. 3, the light path between mirror 17 and photo-cell 8 is preferably directed on the helix formed between the strands of the cord to obtain the largest possible variation in the signal from the photo-cell 8. The output from the cell 8 passes to an amplifier 9 and then to a counter 10. The period during which the counter 10 is permitted to operate is that period during which a further photo-cell 7 receives light from the source 16 via an aperture 6 in the disc 2. The size of the aperture 6 may be varied. The counting device may alternatively be pneumatic means.

Title: Improvements relating to negative feedback amplifiers
IPC: H03K4/43
Filed: 1946-12-04
Abstract: 629,898. Sawtooth shaping circuits. BULL, E. W. Dec. 4, 1946, No. 35893. [Class 40 (vi)] In a negative feed-back amplifier for amplifying signals having transient portions, e.g. sawtooth waveforms, distortion of the waveform caused by the delay time of the feed-back loop is corrected by lengthening the duration of the transient portion so that it exceeds the delay which occurs when these portions pass round the feed-back loop of the amplifier. Fig. 1 shows such an amplifier in the frame deflecting circuit of a television receiver. The incoming signals after amplification are separated and the frame synchronizing signals appear at 7 to trigger the discharger 10 which may be a blocking oscillator. A sawtooth waveform is produced across capacitor 8 by charging it through resistor 9 from the H.T. supply and discharging it through the discharger 10. The sawtooth voltage is amplified in the stage 11 and a sawtooth current flows through the deflecting coils 16, the linearity of the sawtooth waveform being improved by feed-back to the input of the amplifier over conductor 20. The delay in the feed-back loop causes the maximum negative feed-back to be applied when the flyback portion of the input sawtooth voltage has terminated and an input voltage as shown in Fig. 3 is applied to the grid circuit of valve 11, the negative going portions of which are rectified by the valve and prevent the frame and line components of the television raster from interlacing correctly. This distortion of the input waveform is corrected by lengthening the flyback time of the voltage produced across capacitor 8 by means of the network 25, 26. During the charging period both capacitor 8 and 26 charge up from the H.T. supply and during discharge capacitor 26 rapidly discharges through the discharger 10 but capacitor 8 is more slowly discharged via resistor 25. If the discharging of device 10 terminates before capacitor 8 has fully discharged the remainder of the discharging current flows into capacitor 26.
