Title: Vehicle suspension systems
IPC: B60G17/08
Filed: 1972-09-15
Abstract: 1450765 Automatically adjustable fluid dampers; valves D C WITT 17 Sept 1973 [15 Sept 1972] 42947/72 Headings F2S and F2V [Also in Division G3] A vehicle suspension system includes a fluid damper (Fig. 1) with a restricted orifice 18, and control means which vary the cross-sectional area of the orifice automatically in response to a signal related to the vertical velocity of the vehicle body. A signal from an accelerometer (Fig. 3) is integrated and filtered and causes electromagnetic (Fig. 2) or hydraulic (Fig. 4) adjustment of the orifice in response to transient variations in vertical vehicle body velocity. Obtaining the signal. Fig. 3.-The mass 51 of the accelerometer is mounted on the vehicle body 13 in the vicinity of the damper. Vertical acceleration of the mass is sensed by a piezoelectric element 54. The signal is integrated by an amplifier 65 and the resulting velocity signal is filtered by the resistor 66 so that the low frequency velocity signal components generated by a steady vertical acceleration of the vehicle body 13 are removed and only the transient components of the velocity signal remain. This filtered signal is passed either to an electrohydraulic transducer (not shown) influencing the spool valve of Fig. 4, or to coils 45, 46 influencing the electromagnetically operated valve of Fig. 2. Adjusting the orifice electromagnetically, Fig. 2.-Fig. 2 shows in more detail the flow path 17 of Fig. 1 and its restriction 18. Flow in each direction is controlled by one of the orifices 30A, 30B, the other being by-passed by its associated non-return flap valve. The size of the orifices is adjusted by electromagnetic actuation of a rod 39 carrying enlargements 49A, 49B, when current flows in the coils 45, 46. Bowed leaf springs 48A, 48B engage between fixed discs 28A, 28B and flanges 47A, 47B on the rod 39 to bias the rod to its central position. Adjusting the or flee hydraulically, Fig. 4.- Fig. 4 shows in more detail the flow path 17 of Fig. 1 and its restriction 18. Flow in each direction is controlled by one of the orifices 83, 84 the other being closed by its associated ball valve. An increased pressure is supplied from the transducer to one or other of end ports 80, 81 to move the spool 87 to restrict one or other of the orifices 83, 84.

Patent GB-1031517-A (GB)
Title: Methods of producing vapours having at least two components
IPC: C23C16/448
Filed: 1962-12-04
Abstract: A vapour mixture of constant composition is continuously produced by the evaporation of a liquid mixture 4 of corresponding composition from the surface of a porous glass frit filter 2, or other capillary diffusion barrier, saturated with the liquid mixture by capillary flow of the liquid to the filter from vessel 5.  The underside of the filter is packed with glass beads 3.  At the commencement of the evaporation, a carrier gas, e.g. hydrogen, is passed through evaporation chamber 1 from source 13 via valves 15 and 16. Initially, the vapour mixture obtained in chamber 1 is richer in the more volatile component of the liquid mixture, and the mixture of vapour and carrier gas is exhausted from the system via valves 18 and 20. After this initial period, the vapour mixture obtained in chamber 1 by evaporation of the liquid is identical in composition to the liquid on the filter surface, and may be passed with the carrier gas into vessel 6 via valve 17. The capillary flow of liquid to filter 2 is maintained by keeping the bulk liquid 4 at a level 21 below the filter, and heat may be supplied to vessel 5 to aid the evaporation if necessary.  Other capillary diffusion barriers mentioned are bundles of capillary tubes, bundles of rods, layers of particulate material, and porous media such as blotting paper.  The vapour mixture entering vessel 6 may be thermally decomposed to deposit a layer of crystalline material on a heated substrate wafer 11 on support 7.  An induction coil 8 provides the heating means for the wafer, and the temperature of the wafer and support is measured by the thermocouple 10 enclosed in quartz support 9.  The composition of the crystal layer may be altered by changing the rate of evaporation of the liquid mixture or by changing the rate of flow of the liquid to the filter, since these changes will temporarily change the composition of the vapour mixture. The method can be used for the production of superconducting compound films or epitaxial layers. Two examples are given, illustrating the evaporation of a mixture of vanadium tetrachloride and silicon tetrachloride to obtain a superconducting compound V3Si, and the evaporation of a mixture of phosphorous trichloride and silicon tetrachloride to obtain an epitaxial layer of N-type silicon, respectively. Production of Nb3Sn and Nb-Ti alloys, germanium and intermetallic compounds is referred to.

In a toothed Reduced/Direct two-speed gear for a washing machine, wherein a hollow output shaft 2 integral with a V-belt pulley 11 and coaxially surrounding a gear input extension shaft 1 is selectively clutched to a reduced speed gear member 5 or the input extension shaft 1, the Direct drive clutch is a coil spring friction clutch which comprises a coil spring 23 frictionally secured to the input shaft extension and contractible or expansible into clutching engagement with the hollow output shaft and is actuated by a spring-returned stationary solenoid 40 through a rotating or non-rotating shift sleeve 19 and at least one shift pin extending axially through the pulley or radially through the hollow output shaft. The Reduced drive clutch between the toothed gear and the pulley may be a plate or dog clutch actuated by a further or the said solenoid, or, as shown. a double-acting one-way clutch 14 permitting Reverse operation. The gear may provide two speeds when used with a single speed electric driving motor or two speeds for each speed of a multi-speed motor. As shown, an epicyclic gear comprises a carrier 5 having planets 6 meshing an input sun 3 and a fixed ring 8. A solenoid rod 16 has an end directly engaging the sleeve 19 against which is spring-urged a disc 15 carrying pins 13 extending through the pulley 11. For Reduced drive, the hollow output shaft 2 is connected through the one-way clutch 14 to the carrier 5, and for Direct drive the solenoid is energized to axially move the pins so that one is engaged by the bent-up end 24 of the contractible spring 23 to clutch the shafts 1, 2 together, the one-way clutch 14 releasing. In a two-speed countershaft gear (Fig. 2, not shown), one of the pins 13, directly connected to the sleeve 19, is engaged by the bent-up end of a drag spring frictionally entrained by a beaker-shaped member which surrounds the contractible clutch spring 23, is rotatable on the shaft 1, and has a recess through which projects the clutch spring bent-up end 24. In Fig. 3 (not shown), the sleeve 19 has a conical bore by which one or more pins radially extending through the hollow shaft are cammed into the path of the bent-up end of a drag spring frictionally entrained by a bush engaged by a clutch spring expansible into engagement with the bore of the hollow shaft. In Figs. 4, 5 (not shown), the solenoid acts on the sleeve 19 through a fork having sleeve groove engaging rollers of synthetic plastics. The sleeve 19, pins 13 and other gear parts may be of synthetic plastics.
