Patent GB-1210394-A (GB)
Title: Improvements in and relating to braking systems
IPC: F16D65/28
Filed: 1967-11-09
Abstract: 1,210,394. Vehicle braking systems; diaphragm pistons. ROYAL INDUSTRIES Inc. 9 Nov., 1967 [14 Nov., 1966], No. 51109/67. Headings F2F and F2T. A service/emergency braking assembly comprises two diaphragms separated at their peripheries by a spacing ring with undercut portions on its opposite faces and urged together at their centres by a resiliently mounted brake actuating rod extending axially through the housing, ports being arranged to apply fluid pressure alternatively to the space between the diaphragms or to the space between one diaphragm and the housing opposite to the brake actuating rod. In Fig. 1 the brake actuator 13 is driven for normal braking by a diaphragm 33, for emergency braking by a diaphragm 35 and for parking or " fail-safe " purposes by a spring 16 acting through a diaphragm 14 and rod 18 which bears on the diaphragm 35. Normally compressed air is admitted to chamber 22 to hold the parking brake off. For normal braking, compressed air is admitted to chamber S between the two diaphragms through a port in the sealing ring 34 (details in Fig. 8, not shown) and moves the actuator 13 against a spring 32. In an emergency, compressed air is admitted through a port (not shown) into chamber E in controlled increments, thereby increasing the braking effect. The sealing ring (details in Figs 3-7, not shown) is of such a thickness as to accommodate the fluid-entry port and yet permit the two diaphragms to be close enough for effective operation of the emergency diaphragm 35. The sealing ring has a flange (34b) defining an undercut portion to receive the diaphragms and is grooved (34c) to prevent bulging and leakage. A non-friction material is applied to the parts of the diaphragm which rub against one another. Control system (Fig. 9).-Air from a compressor 50 passes via reservoirs 51 and 52 and the normal brake pedal 56 to a valve 57 whence it flows to the ports 34P giving access to the chambers S in the brake actuators. Air for the spring-loaded booster chamber is supplied from a further reservoir 53 connected to 52 via a non- return valve 54. This air is normally supplied via a quick-release valve 64 to hold the brakes off but can be vented to the atmosphere by a valve 61, e.g. as a parking brake. The emergency supply for operating the diaphragm 35 is taken from the reservoir 53 through a manually controlled valve 62 which allows the pressure to rise incrementally. The quick-release valve 64 may be replaced by a differential-pressure check valve 70 (Fig. 10, not shown). This control system is the subject of Specification 1,210,395.

Title: Process for the gas chromatographic separation of hydrocarbons
Inventor: EPPERT GUNTER
IPC: G01N30/00
Filed: 1966-11-16
Abstract: Hydrocarbon mixtures are analysed into classes such as straight chain, branched, aromatic, unsaturated or cyclic by gas chromatography in a molecular sieve column maintained at a temperature high enough to loosen the binding of the components to the sieve (some of the components not being bound at all) with flow reversal through the column as soon as the unbound components are detected.  In the figure "Phase 1" carrier gas from line 4 passes through valve 5, injector 1, vaporizer 3, valve 6, column 7 in heater 8 maintained at 300-550 DEG C, detector 9, valve 11 and line 12. After detection of the unbound components on recorder 10, controller 13 reverses valves 5, 6, 11 so that carrier gas now flows from valve 5 to valve 11 and hence by detector 9 back through the column and out through valve 6 and line 12.  After a predetermined time interval controller 13 again reverses the valves and causes another sample to be injected.  The whole apparatus is in a thermostatted enclosure. Specified molecular sieves are Types 5A and 10X.

Title: Fluid resistors
IPC: F16K47/04
Filed: 1974-11-27
Abstract: 1483474 Fluid regulation SYBRON CORP 27 Nov 1974 [3 Dec 1973] 51408/74 Heading G3H [Also in Division B3] A fluid resistor comprises a laminated member 36, Figs. 3 and 4, having a rigid substrate provided with a flat surface and a metallic layer, e.g. copper, of substantially constant thickness deposited on the surface. The member 36 has a groove 35 formed through the metallic layer by photoetching. A rigid plate 42 co-operates with the grooved surface of the member 36 to close the groove and thereby define a capilliary passageway extending between inlet and outlet passage means. In the embodiment shown the plate 42 is formed with an inlet passage (60) therethrough, Fig. 2 (not shown),and is angularly adjustable to vary the effective length of the capilliary passageway between the inlet passage and an outlet passage 40 in the member 36. Alternatively the member and plate may be relatively adjustable along a linear path. In another embodiment, Figs. 9 to 14 (not shown), the laminated member (140) and plate (134) are relatively fixed. However, the member (140) has a pair of grooves (160, 162) formed therein and the plate (134) has two pairs of inlet and outlet apertures, whereby two different resistance paths are available. Alternatively, the apertures may be so arranged in the plate (134) that by its assembly in one of two alternative orientations only one of the grooves is effective. The substrate of the laminated member may be of aluminium in which case it is initially coated with a layer of material resistant to photoetching, e.g. polyethylene, epoxy or polyester adhesive, before receiving the copper layer. The etched copper layer may be coated with a layer of nickel. The substrate may instead be formed of a substance resistant to photoetching, e.g. fibreglass, in which case the initial coating is not necessary. The plate may be of carbon-filled p.t.f.e.

Filed: 1972-11-08
Abstract: 1373883 Knitting machines IRO AB 8 Nov 1972 [29 Nov 1971] 51530/72 Heading D1C A yarn storage feeder may operate in either a positive yarn feed mode, or an intermittent yarn feed mode: when operating in the positive feed mode (see the Figure) the textile machine is switched off if the yarn reservoir V falls below a specified minimum quantity. Yarn F from a bobbin 8 is wound on a drum 2 tangentially and pressed down by a transport element 9, which if it tilts too far causes a rod 15 to open a switch 17 thus switching off the textile machine motor 6 which drives the drum 2 also. If the yarn breaks between the bobbin 8 and the drum 2 a stop motion switches off the machine, but as the machine slows down yarn continues to be drawn from the reservoir, but is not replaced. After several such breaks the reservoir could fall below the specified minimum and the machine will be stopped to enable the yarn reservoir to be replenished by hand or by auxiliary devices. The pivoted arm 24 may also act as a stop motion. In a modification the arm 24 may be swung downwards parallel to the drum axis, to provide intermittent yarn feed. In this case the transport element 9 is modified to switch a clutch or separate drive to the drum 2 so that the drum can be driven independently of the textile machine drive.
