Title: Improvements in or relating to endless track vehicles
IPC: B62D55/02
Filed: 1927-10-14
Abstract: 279,442. Kegresse, A. Oct. 20, 1926, [Convention date]. Endless-track vehicles.-In an endless-track vehicle the track-driving pulleys 1 are mounted directly on .the chassis and are arranged at the forward ends of the tracks, the idler pulleys 2 and carrier wheels being mounted on a single axle 3 connected by springs 4 to the chassis. The top run 6 of the track is thus the taut or driving run, and it is stated that lack of alignment between the driving- pulley and the carrier wheels due to flexure of the springs does not tend to cause the track to leave the pulley.

Title: Quick-action release and braking valve for vacuum brakes
IPC: B60T13/46
Filed: 1958-08-26
Abstract: 838,585. Vacuum brakes. KNORR-BREMSE G.m.b.H. Aug. 26, 1958 [Aug. 30, 1957], No. 27358/58. Class 103 (1). A quick-action release and braking valve 1 for an automatic vacuum brake having a twochamber brake cylinder 27, comprises a diaphragm 5 separating a chamber 9, connected to the lower brake cylinder chamber 25, from a chamber 15 connected to brake pipe 39. For braking, an increase in brake pipe pressure moves diaphragm 5 and a rod 7 down to open a valve 11 to admit atmosphere pressure to chambers 9 and 25, valve 11 closing when the pressures in chambers 9 and 15 equalize. For quick release, increase in vacuum in the brake pipe moves diaphragm 5 upwards and rod 7 opens a valve 21 to connect the upper and lower brake cylinder chambers 29, 27 via pipe 23, valve 35 and chambers 19, 17 for rapid pressure equalizing and brake release. The valve 1, brake cylinder 27 and reservoir 31 are initially evacuated from the brake pipe 39 via non- return valve 41 and chamber 17. Should the quick release not be required, e.g. on trains only partially equipped with valves 1, then valve 35 is rotated to block the pipe 23 to chamber 19, so that on brake release the vacuum in the brake pipe acts through non-return valve 37 and valve 35 to the lower chamber 25, brake application being as before. The inlet valve 11 may be throttled for more uniform braking, and a choke 43 may be inserted between valve 41 and chamber 17 to produce the release process as a function of time by controlling the rate of flow of air from chamber 17 to pipe 39 after equalization of brake cylinder chambers 25 and 29.

Abstract: 1490182 Heat-treating heat-recoverable alloys RAYCHEM Ltd 15 Nov 1974 [17 Nov 1972] 27937/76 Divided out of 1490181 Heading C7A A heat-recoverable alloy is treated to reduce loss of reversibility at ambient temperature between its austenitic and martensitic states (austenitic being the form which is stable at high temperatures and capable of undergoing transformation to the martensitic state on cooling) by ageing at a temperature above M s  while in the austenitic state. Before ageing it may be necessary to heat the alloy to a temperature at which it is fully austenitic (e.g. in the case of brass to 800‹C to put it entirely in the beta phase) and then quenching to retain that state. Suitable quenching temperatures are 20- 50‹C, and ageing conditions 50‹ -100‹C for 10 minutes to 24 hours. Alloys particularly referred to are those defined by lines 40 in Fig. lb, 20 in Fig. 4b, and 20 in Fig. 4c and also 26À3% Zn - 4% A - balance Cu, 37À3% Zn - 0À5% Al - balance Cu, and 10À5% Al - 9% Mn - balance Cu. The process is also applicable to alloys based on gold and silver. Typical treatments carried out after ageing include deformation at -50‹C or -79‹C in the martensitic state followed by slow or rapid heating to 40‹C or 200‹C for recovery.

Filed: 1976-07-07
Abstract: 1499257 Fluidic control circuits HORIX Mfg CO 7 July 1976 [11 Nov 1975] 28215/76 Heading F1P [Also in Division B8] A pneumatic pressure system controls the operation of means for opening a filling valve of a container filling machine, by the use of three fluidic control devices. Device 98 directly controls pneumatic relay 82 to open the filling valve, but is itself controlled by the state of the other two devices 45, 59, so that the initially actuated device 45 may operate at a lower pressure to improve response and repeatability, while the actuating pressure of control device 98 is sufficiently high to operate relay 82. The raising of a bottle to be filled closes by-pass 86 and opens by-pass 38 to stop air-flow through tube 54. When valve 68 is opened by actuating member 69 (operated by a cam), control device 59 changes state so that no deflecting airflow enters control device 45, thereby causing this device to change state also. Valve 68 closes and control device 98 changes state to allow air-flow through tube 81 to operate relay 82 and open the filling valve. A line from valve 68 to control chamber 80 of control device 98 ensures that the filling valve is not opened until after the valve 68 is closed, to prevent over filling if the machine stops moving while valve 68 is open.

A surface of a polyvinyl fluoride film is continuously brought into intimate contact with a moving, relatively highly thermally conductive solid surface maintained at a temperature of 40 to 135 C., whereby the film passing thereover is heated to the temperature of the moving surface and the film while in contact with this surface is passed through the secondary envelope of a steady flame of a burner disposed parallel to the film and transversely to its direction of travel. The flame is free from yellow luminosity and is supplied with a gaseous mixture consisting of a paraffinic or olefinic hydrocarbon fuel, preferably propane, oxygen and nitrogen, the " fuel equivalence ratio " of the gaseous mixture being 10À5 to 1À20 and its oxygen ratio 0À15 to 0À25. The distance from the free surface of the film to the discharge opening or openings of the burner is greater than the length of the unimpeded primary envelope of the flame, and the film is exposed to the flame for 0À01 to 0À5 second. The film is maintained in contact with the moving surface for a time after it has left the flame. The " fuel equivalence ratio " is defined as the ratio of the amount of hydrocarbon fuel present in the gaseous mixture supplied to the burner to the amount of hydrocarbon fuel necessary for complete stoichiometric combustion. The " oxygen ratio" is the ratio of the amount of oxygen present in the gaseous mixture supplied to the burner to the total amount of non-fuel components in the mixture, said components including chiefly oxygen and nitrogen. The " primary envelope" of the flame is defined as the luminous, pale blue inner portion of the flame nearer the discharge opening of the burner and the " secondary envelope" of the flame is defined as the fainter, less luminous sheath surrounding the primary envelope. Fibre-reinforced polyester structures clad with polyvinyl films treated by the process of the invention may be produced by moulding and curing a mixture comprising at least one linear polymeric ester containing recurring ethylenic unsaturation, at least one addition-polymerizable ethylenically unsaturated monomer, and reinforcing fibres, using as a mould release sheet a polyvinyl fluoride film of which at least the surface in contact with the mixture has been treated by the process of the invention.
