Title: Improvements in or relating to starting handles for internal combustion engines
IPC: F02N1/02
Filed: 1924-05-14
Abstract: 228,051. Brown, H. N. May 14, 1924. Turning-gear.-In a starting-device which is disconnected if the engine turns backwards, a handle shaft k and a driven shaft a carrying a clutch member c are movable longitudinally together against the tension of a spring d, the shaft a being driven from the shaft k through a casing t rotating with the shaft k and fixed as regards longitudinal movement; within the casing is a clutch and a member which disengages the clutch when the shaft a turns backwards. As shown in Fig. 1, the casing t is connected to the shaft k by a keyway 3 and a key 2, which also secures a flanged sleeve p connecting the shafts k, a as regards longitudinal movement. The clutch connecting the casing t and the shaft a comprises a smooth sleeve 6 connected to the shaft a by a key 7 and keyway 8. Between the sleeve and the casing are floating segments 10 having clutch rollers 11 in inclined recesses 12, which transmit the clockwise rotation of the shaft k to the shaft a. The disengaging member is a loose ring 15, carrying pawls 17 in engagement with ratchet teeth 19 on the fixed bearing b, and having projections 16 engaging between the segments 10. When the engine and the shaft a turn backwards, the ring 15 is held, and the segments 10 are arrested by the projections 16, so that the rollers 11 come into the deeper ends of the recesses 12 and the rotation is not communicated to the shaft k. In a modification, the shaft k is replaced by a sleeve, a key on the casing t entering a key-way in the sLeeve and an annular recess in the shaft a. In a further form, the roller clutch 10, 11 is replaced by a floating ring having pawls engaging teeth on the casing t and on the sleeve 6; if the engine turns backwards the connection is released by the projections 16, which have inclined faces acting on corresponding faces on the pawls in engagement with the sleeve 6.

Title: Improvements in and relating to domestic washing machines
IPC: D06F13/02
Filed: 1941-09-18
Abstract: 550,669. Washing machines. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 18, 1941, No. 11963. Convention date, Sept. 19, 1940. [Class 138 (ii)] For controlling the supply and distribution of liquids of a machine for washing and centrifugally drying clothes, the pump 7 drives liquid from the bottom of the casing through a discharge tube 15, Fig. 3, having ports 17 at its lower end and a nozzle 16 at the upper end rotatable so as to discharge, for washing, on to' the filter ring 28 of the tub 2, for drying, between the tub and the casing; and for draining, into the inner, open end of a conduit 30 mounted on the casing and leading to a drain. The tube 15 is mounted in a hollow post 12 fixed in a casting 11 secured to the bottom wall of the casing and supported in a rubber bushing 13a in the bottom 13 of a trough 14 fixed to the wall of the casing above the liquid level therein. The tube end is fixed to the enlarged end of a rod 19 extending through a stuffing box 20 in the casting 11 and having an arm 21 pin-andslot connected to a hand-lever 25 adjustable to the three positions for use. Above the drain 9 feeding the pump from the floor of the casing is a drain 32 from the trough 14 leading to a depending sleeve 33 with external ribs on which slides a sleeve 35 having a rubber ring 36 to enclose the drain 9 and movable up and down by a rod 37 sliding in brackets 38 on the casing and pressed down by a spring 42 acting on a cam 43 fixed to the rod which engages a cam 44 on the discharge tube 15. Thus, when the nozzle 16 discharges into the tub in washing, the rod 37 and sleeve 35 are up and liquid is pumped from the casing floor. When the nozzle delivers to the drain 30 the sleeve 35 is. down and liquid from the trough is pumped to the drain. While the discharge nozzle 16 thus engages the drain conduit 30 the casing may be emptied by lifting the sleeve 35 and rod 37 by a pull on the ring 47 attached to the top of the rod. During centrifuging rinsing water may be supplied through a pipe 49 into the receptacle directly or through a pipe 50 on to the filter to act as a brake to limit the speed of rotation. Ribs along the outside of the sleeve 33 allow liquid over the top edge of the sleeve 35 to run to the pump and thus define the liquid level in the outer casing.

Title: Improvements in and relating to the construction of roofings, partitions and the like
IPC: E04C2/08
Filed: 1931-04-22
Abstract: 377,235. Roofs, decks, partitions, and like surfaces. PLUMMER, H. L. and IRWIN, D. L., Lincoln House, High Holborn, London. April 22, 1931, No. 11964. [Class 20 (iv).] A flat metal sheet for roofs, decks, partitions, and like surfaces, of the kind provided with reinforcing ribs 12 and with a plain flange 2 and a curved flange 3 for engagement with adjacent sheets, is formed with slots 15, 18 which facilitate assembly of the sheets. Adjacent to the slots 15, the ribs 12 are of reduced cross section for engagement within parts of ribs formed on an adjacent sheet. Hook bolts may be passed through the overlapping base portions of the ribs to secure the sheets to a portion, rafter, or like member, the slots facilitating access to the bolts. Portions 16 of the rib flanges exposed by the slots 15 serve as seatings for metal covers. Where the sheets overlap, the effective thickness of the surface may be only that of two sheets, by the arrangement of the overlapping portions of the ribs, as shown in Fig. 6, the lower rib 12 having exposed flanges wide enough to accommodate the flanges of the upper rib 14. The flanges 2, 3 are cut away, as shown, at one end of the sheet, and at the opposite end are formed with pressed-in portions 8, 9, adapted to be overlapped by portions 10, 11 of an adjacent panel. In a modification, the flanges are cut away and pressed in at the same end. The sheets when used in making a roof may be covered by bituminized felt in sheet form with an intervening layer of heat-insulating material.

Title: Improvements in fluid pressure operated devices
Inventor: DAVIDSON ROBERT
IPC: B30B1/08
Filed: 1956-04-20
Abstract: 860,191. Mechanical presses. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 21, 1957 [April 20, 1956], No. 12138/56. Class 87(2). [Also in Group XXIII] A bell crank is pivoted at 10 for the frame of the press, with a shorter arm 11 pivoted at 13 to one end of air cylinder 14 and a longer arm 7 connected through a link 5 to the press ram 3. On the upper pivot pin 9 of the link 5 are also mounted rollers 9. An arm 18 is pivoted at 19 to the press frame and at its upper end, at 17, to the piston-rod 15 and is extended at its lower end to form two cams 20. The cams 20 are shaped as shown to provide curved recesses and to fit over the rollers 9 in the position shown, where they are restrained by adjustable stops 21. Compressed air enters the cylinder 14 in a direction to force the piston-rod 15 inwards, but, due to the engagement of the cams 20 with the rollers 9, the cylinder 14 moves towards the pivot 17 and in so doing rotates the bell crank so that the arm 7 lowers the ram nearly to the bottom of its stroke. The rollers 9 then move out of engagement with the cams 20 and, as the distance between the pivots 12, 17 continues to shorten, the arm 18 turns the cams 20 which ride on the rollers 9 and give the ram a short, final pressure stroke. In a modification the bell crank is replaced by a lever 7a pivoted to the frame at 10a and connected at its other end to the ram 3a through pivoted links 5a. Rollers 9a are mounted on the pivot pin 8a. The air cylinder 14a has one end pivoted at 13a to the lever 7a at a point nearer the end 10a than 8a, and its piston-rod is pivoted to an arm 18a which operates cams 20a. At the position shown, with the ram 3a at the top of its stroke, the recesses in the cams 20a fit over the rollers 9a, and thus when air enters the cylinder 14a to force the piston-rod outwards the latter is restrianed from movement and the cylinder 14a moves in the opposite direction, lowering the arm 7a through a distance which is magnified at its far end and bringing the ram nearly to the bottom of its stroke. The rollers 9a are then clear of the cam recesses and further movement of the pistonrod causes the cams to ride over the rollers 9a so imparting the required short, final pressure stroke to the ram. The movement of the cams is limited by an abutment on a plate 21a.

Title: Improvements in or relating to the manufacture of toilet soaps
IPC: C11D15/00
Filed: 1928-04-26
Abstract: 319,804. Villain, P. April 26, 1928. Soaps, compositions for making.-In the maufacture of perfumed soaps, ordinary rosin is replaced by an aromatic composition consisting of terpenes, sesquiterpenes or polyterpenes; synthetic or ordinary resins; and the residues from the extraction of flowers by fats or solvents, known as resinoids, resinodors, floral wax or resinaromes. These are dissolved in a suitable solvent, e.g. methyl alcohol, diacetone, cyclohexanol, propyl alcohol, isopropyl alcohol, monobuty alcohol, ethylene glycol or trichlorethylene, and emulsified with a mixture of ammonium sulphoricinoleate and glycerine, or other wellknown emulsifier. The whole mixture is heated to 70‹-90‹ C. and stirred to obtain a homogeneous emulsion, which is dissolved in the soap during the saponification of the whole. The terpenes may consist of the pure bodies, or mixtures thereof, e.g. residues from the removal of terpenes, by-products of the distillation of essential oils, or admixed with essential oils, isolates, e.g. geraniol, or perfumery chemicals, e.g. phenyl ethyl alcohol. In an example, the composition suitable for an Eau de Cologne soap comprises 8-10 lbs. of a mixture of terpenes, 6-4 lbs. of synthetic or natural resin, 1 lb. of gum benzoin and 8 oz. wax residue from orange flower oil extracted by solvent, added to a mixture of 8 lbs. industrial methylated spirit at 65‹ O.P., 7 lbs. cyclohexanol or propyl alcohol, 1¢ lbs. glycerine, and 1 lb. ammonium ricinoleate. The whole mixture is heated gradually to 80‹ C., and stirred to obtain a homogeneous, clear emulsion, which is then added to a soap base consisting of 65 lbs. tallow and 20 lbs. copra, when the same is " boiling on strength," caustic soda being added if necessary, and the saponification completed. For a transparent soap, a small excess of alkali must be left, and the soap base, after solidifying, flaking and drying, is transferred to a vacuum still with reflux and remelted with 40 per cent to 50 per cent of industrial methylated spirit and 8-10 per cent of glycerine, the whole being heated to 80‹ C. and then raised gradually to 97‹ C., and boiled under 5 per cent increase above atmospheric pressure for 3 hours. When transparent, it is cooled to 75‹ C., 1¢-2 per cent of an Eau de Cologne mixture of essential oils is added, stirred and poured into frames or moulds. For a milling soap, the soap base after saponification must be neutral.

Title: Improvements in or relating to Tipping Mechanism for Railway and like Wagons.
Inventor: PATTISON WILLIAM
IPC: B65G67/00
Filed: 1916-08-30
Abstract: 102,906. Pattison, W. Aug. 30, 1916. Rotary tipplers.-Railway and like wagons are chained to a platform f and supported by spindles q so arranged that, on the removal of the supports g from beneath the platform, the wagon tips automatically. The spindles q are mounted in the upper ends of hydraulic jacks, the rams m of which are mounted on shafts e, which can be rotated to bring the jacks into the position shown in dotted lines in Fig. 1, to permit the passage of a wagon on to the platform. Means (not shown) are also provided for moving the rams m along the shaft c, in order that the spindles q may be arranged so that the line connecting them is below and a little to one side of the centre of gravity of the loaded wagon. An eccentric strap s<2> mounted on the end of the spindle q raises the plunger t, Fig. 6, of a pump u when the wagon tips, and since the suction valve of the pump communicates with the reservoir n and the delivery valve with the pressure cylinder of the ram m, when the empty wagon commences to swing back, water will be forced into the pressure cylinder and a braking action will be exerted. In addition, the spindles q will be raised, so that the platform comes to rest in a position in which the supports g can readily be put in place. A return valve z' allows the water to flow back into the reservoir, and the platform descends on to the supports.

Patent GB-962087-A (GB)
Title: Signal responsive apparatus
IPC: G01H9/00
Filed: 1963-03-29
Abstract: 962,087. Photo-electric systems. SPERRY RAND CORPORATION. March 29, 1963 [April 4, 1962], No. 12497/63. Heading G1A. [Also in Division G4] A device responsive to one or a combination of frequencies in a signal comprises one or more light-transmissive rods rigidly supported in a mounting at one end and free to vibrate at the other, means for supporting a mask at the free end or ends and a photo-cell behind the mask receiving light passing through the rod or rods and the mask. In the case of a single rod 3, Fig. 1, the mounting 2 is connected to a vibrator 7 e.g. a plate of piezoelectric material. The mask 4 is adjacent the free end of the rod and the photo-cell 5 receives light passing along the rod and through the mask. The output of the photo-cell is amplified in a triode 6. If the rod is vibrating in a sine wave and the mask 4 is half clear and half opaque, the output signal is a rough square wave. In the form of Figs. 3-5 there are two rods, the mask being shown adjacent the ends. The mounting is sloped so that the rods are of different length and accordingly vibrate at different frequencies. The mask is made photographically by shining light along the rods and with a photographic plate in the mask position, developing the plate and using it as the mask. Fig. 3 shows that each rod is aligned with an opaque area so that if each rod is stationary there is no light transmitted and no output. If one or both of the rods vibrate a corresponding signal is generated by light passing on each side of the opaque areas. In Fig. 4 the mask is made with the upper rod vibrating and the lower one stationary. This mask gives zero output when the applied signal causes the upper rod only to vibrate. To obtain a maximum signal in a matching condition, the mask is made as in Fig. 4 but using a positive image film and a mask of the kind in Fig. 3 is added to cut out light from stationary rods. The resultant mask, Fig. 5, therefore gives zero output when the rod is stationary but a maximum when vibrating. An assembly of rods 9, Fig. 6 responding to different frequencies gives a maximum signal when the signal applied to vibrator 11 contains the combination of the resonant frequencies of the three rods opposite the transparent areas of the upper mask and zero signal when no signal is applied. In Fig. 7 a large number of rods 17 are mounted on an opaque base 18 to be vibrated by the plate 22. A photographic mask 20 is made to respond by a maximum signal to a particular input signal by passing light through all the rods while they are vibrated by the input signal, then developed as in Fig. 5, combined with a mask as in Fig. 3. The input signal may be a speech signal derived from a microphone or a signal derived by scanning a character or a line of characters. The photoconductive plate 21 provides the photo-cell. A pair of devices as in Fig. 7 may be connected to recognise a two-syllable word by connecting one of the devices, responding to the first syllable to a relay which switches on the lamp for the second device, responding to the second syllable.
