Title: A safety ski-fastening device
IPC: A63C9/085
Filed: 1945-08-09
Abstract: 596,836. Skis. LANGLOIS, A. Aug. 9, 1945, No. 20429. Convention date, May 12, 1944. [Class 132 (i)] A device for fastening a boot on a ski comprises a plate provided with upwardly projecting L-shaped members between which the boot is wedged, the plate being mounted on the ski so that it can swing, in a plane parallel to the upper face of the ski, about a pivot located adjacent to the boot-heel but having spring lockmg means so that swing can only take place when the transverse strain exceeds a certain value. In Figs. 1 and 2, the boot is supported on plate 1 which rests on ski A, the plate being pivoted about screw 24. Plate 1 is provided with two L-shaped members 4 and with ribs 22 which run in grooves 23 in the ski, these grooves forming arcs of a circle having its centre at 24. Projection 11, forming part of cross-piece 7 at the front of plate 1, is engaged by a corresponding notch in latch 12, but as soon as the torque is sufficient to cause projection 11 to drive the latch 12 away against the thrust of spring 13, plate 1 is free to swing about pivot 24. The Specification as open to inspection under Sect. 91 contains additional Figs. 3 and 4 (both Cancelled) in which plate 1 has a recess 33 on its underside which is engaged by ball 30 until the torque overcomes the thrust of spring 31.

Title: Improvements in or relating to typewriters
IPC: B41J19/14
Filed: 1951-08-30
Abstract: 714,343. Typewriters. ZINT, G. Aug. 30, 1951, No. 20465/51. Class 100 (4) Letter-spacing mechanism.-In a typewriter the platen carriage is continuously reciprocated at a constant speed from left to right and right to left and typing takes place in both directions of carriage travel so that one line is typed in the normal way but the next is typed starting at the right-hand margin. Letter-spacing is determined by the operator typing in synchronism with an audible signal sounded at regular intervals of carriage travel. As shown the typewriter carriage 98, Fig. 1, is mounted on rollers and guides and is reciprocated by an electric motor 37 mounted on a plate 33 supported from a bracket 29 attached to the typewriter frame. The motor 37 rotates a sleeve 39 and a collar 40 carrying a crank pin 42 engaging with a radial pin 66 on a collar 65 driving a shaft 62 provided with two oppositely directed helical grooves engaged by a follower 80 to which the carriage 98 is adjustably attached. The follower 80 contains a tooth member pivotally mounted so that when it reaches the end of its travel in one direction the end surface of the groove pivots it to engage in the other groove. Rotating with the shaft 62 is a large collar 67 having several radial pins 68 which raise a striker 70 against the pull of a spring 74 which with the passing of the pins 68, causes the striker 70 to hit an anvil 75 giving the letterspacing audible signal. Line-spacing mechanism.-Line spacing occurs automatically at alternate ends of successive lines, the platen 101 being rotated a line space by a squared rod 110 which non-rotatively but slidingly passes through a ratchet wheel 127 fixed relative to the typewriter. Wheel 127 is advanced one space when either of a pair of stops 178, 182 on an extension 175, 180, 181 of the carriage, contacts a rod 189, Fig. 8. The rod 189 is biased into a central position by equal springs 192 and carries an adjustably mounted finger 201 engaging a projection 202 on a collar 147 integral with a pawl carrying assembly 143, 153, 155, 160, 161, 162, 163, Figs. 7a and 8. The movement of the rod 189 slides the finger 201 either to the left or right of the projection 202 allowing the pawl carrying assembly to swing clockwise by the pull of the spring 155 and effect one line space. The assembly is moved backwardly into the position shown in Fig. 7a during the course of the travel of the carriage by a cam 176 engaging a wheel 167 on the pawl carrying assembly. This lifts the projection 202 clear of the finger 201 which is moved by the compressed spring 192 below the projection 202 again. A detent pawl 210 prevents backward rotation of the ratchet wheel during this action on the pawl assembly. Both the pawl 210 and the spacing pawl 162 may be moved away from the ratchet wheel 127 by cam 220a integral with a knob 220 when manual adjustment of the platen is required, e.g. to insert a sheet of paper in the machine.

Title: Improvements relating to steam generators
IPC: F22B37/00
Filed: 1924-08-30
Abstract: 235,752. Oddon, J. E. Aug. 30, 1924. Generating combustion products under pressure.-A steam boiler 1, Fig. 3, is heated by a number of internal-combustion chambers 8 in which combustion of a mixture of petrol vapour and air is effected under pressure within catalytic material consisting of asbestos fibre incorporating powdered platinum sufficiently spongy to allow circulation of the gases. The combustion chambers consist, as shown in Fig. 6, of an outer vessel 21 with vertical grooves and radiating ribs 23 and an inner vessel 27 comprising a wire gauze portion 24 through which air under pressure admitted through the pipe 12 passes to the space between the two vessels containing the catalytic material and into which space the fuel is admitted through the pipe 15. The combustion products escape through a pipe 28 passing through a feed water heater 30. The air supply tank 3 and petrol tank 4 are supplied with air under pressure bv a pump 6 and communicate with the heating elements by means of the pipes 12, 15 respectively passing through the boiler. The fuel and air supply is controlled by valves 44, 45 actuated by a lever 43 and link 66 connected to a corrugated elastic chamber 10 subjected to the pressure in the boiler, increase in pressure causing the chamber to collapse and close the valves. The link 66 is also connected by a lever 40 to the valve 42 in the steam outlet pipe 63 of the boiler in such a manner that upon an increase of pressure the valve 42 is opened to allow steam to escape. The pressure in the tanks and in the heating elements is regulated by the device shown in Fig. 5, consisting of a casing 68 divided by a diaphragm 50 into upper and lower chambers in communication with the air supply system and with the exhaust pipe 28 respectively. A drop in pressure of the air allows an elastic sleeve 53 to open the valve 55 and admit steam to the air pump to restore the pressure. When the pressure in the exhaust pipe tends to increase beyond the pressure in the tanks, the diaphragm 50 is raised and actuates a valve 52 to allow an increased discharge of combustion products. The petrol tank is filled through a three-way valve 14, allowing the tank to communicate either with the atmosphere, when it needs replenishing with fuel, or with the air pressure pipe 13. A float 11 in the boiler controls a valve 47 in a steam pipe 64 admitting steam to the feed pump 7. The boiler is bell-shape and attached at its open end to a base 2.

Title: Improvements in and relating to high frequency signalling systems
IPC: H04B1/18
Filed: 1922-07-27
Abstract: 183,838. British Thomson - Houston Co., Ltd., (Assignees of Rice, C. W.). July 27, 1921, [Convention date]. Atmospherics, eliminating or limiting; amplifiers and detectors.-In order to reduce interference from atmospherics, the aerial 1 is coupled to an artificial line 3 constructed for example as described in Specification 191,125, and having an effective length equal to several wave lengths of the received waves. Couplings 4, located at points corresponding to full or half wave lengths, impress the signal currents on the grids of a number of valve amplifiers 5 having their plate circuits connected to a common battery 6 and coupled by a common transformer 8 to a detector 9. A tuning condenser may be connected across the coil 7 in the plate circuits. The coupling coils 4 are so arranged that the desired signal currents cause variations in the plate currents which are in phase and therefore add in amplitude. Strays giving rise to currents of the signal frequency do not give maximum amplitude at all the couplings 4 and their effect is therefore subdued. Strays which are not of the signalling frequency produce out-of-phase currents in the coil 7 and are partially neutralized. A resistance 11 prevents reflection of waves from the end of the artificial line 3.

Title: Process for removing water from a mixture comprising higher alcohols and water
Filed: 1960-06-14
Abstract: Water is removed from a mixture comprising alcohols having 2 or more carbon atoms and water by extracting the mixture with hexane and separating hexane from the extract obtained, thereby recovering the alcohols.  The process is particularly useful for purifying the mixture of higher alcohols obtained as a result of the partial oxidation of normally gaseous hydrocarbons such as propane.  The formaldehyde and acetaldehyde present in such a mixture are separated first.  The resulting mixture may then be subjected to hydrogenation and the methanol present may be separated by fractionating the resulting mixture at a temperature of about 71-77 DEG C.  The remainder is extracted with hexane and preferably the extract is fractionated to recover substantially water-free alcohols and an azeotrope containing water, hexane and a small amount of higher alcohols.  To recover the alcohols from the azeotrope water is added and a part of the alcohol and hexane recovered from the azeotrope may then be returned to the zone in which the azeotrope is found.  The remaining hexane and alcohol can be recycled to the hexane extractor. The remaining water, hexane and the higher alcohols in the azeotrope and the added water are combined with water from the hexane extract and sent to a water stripper.  After removing most of the water the remainder of the material in the stripper, which includes alcohols, hexane and some water, is recycled to the zone in which the azeotrope is formed.
