Title: Improvements in Means for Making or Repairing Roads and like Surfaces.
Inventor: HINES JOHN
IPC: E01C19/21
Filed: 1916-04-17
Abstract: 107,027. Hines, J. April 17, 1916. Cauldrons; surface-heating apparatus; surface treatment with liquid materials. - Relates to portable apparatus for making or repairing road surfaces, and consists in the combination of an air-heating surface with means for forcing or drawing the hot air to a hood or hoods situated over the road surface and means for heating the binding-materials by the hot air and for discharging them on to the road surface within the hod. A suitable filling-material such as sand, chippings, clinker dust, or Portland cement may be heated by the current of hot air and blown upon the road surface. In the form shown, the apparatus comprises an air blower b connected with an air-heating furnace d, the hot air passing between a tar-tank e and a container g for the filler to an outlet pipe h connected to a hood j, the whole being supported on a vehicle framework a adapted for propulsion or trailing. Fig. 4 shows a section through the tar and sand heaters. The air blown through the furnace d passes either directly through a main hot-air trunk f to the outlet h or, by operating dampers k<1>, it may be diverted into a flue k passing around the tar-tank e. Cold air may be admitted through a damper r. The outlet pipe h is connected to the vertex of a hood j, of square pyramidal form, shown in section in Fig. 5. The tar is forced from the tank e by air pressure produced by a pump m and is sprayed within the hood by a pipe l. The filler in the container g is moved by a conveyer n to the outlet h and, by operating a valve q, is blown by the hot air into a passage o delivering inside or outside the hood according to the position of a flap o'. The bottom of the passage o is provided with grooves to distribute the filler.

Title: Industrial trucks
IPC: B66F9/18
Filed: 1962-02-14
Abstract: 938,791. Fork lift trucks. YALE & TOWNE MANUFACTURING CO. Feb. 14, 1962 [March 2, 1961], No. 5618/62. Class 78 (3). The gripping arms 16, 17, Fig. 1, of a lifting truck are movable in unison transversely of the truck as well as in the normal load-engaging manner and to prevent the truck overturning, due to a load being lifted towards the extreme lateral positions of the arms, sensing means are provided which detect lateral movement of the centre point between the arms 16, 17 and operate control and indicating means when a limiting position is reached. The arms 16, 17 are moved by hydraulic rams 26, 27 controlled by the circuit shown in Fig. 10. The sensing means include a cam 33, Figs. 1, 10, which is moved laterally by the arms 16, 17 so that at extreme positions either one or other of ball and check valves 29, 30 are allowed to close by either a rod 36 and pivoted arm 34 or rod 37 and arm 35 as either wheel 68 or 69 runs off the end of the cam 33. When either of valves 29 or 30 are closed further movement of the arms 16, 17 in the same direction is prevented. Movement of the arms 16, 17 is controlled by valves 39, 59, as described in U.S.A. Specification 2,795,346. In one embodiment the cam 33 is moved by rods 86, 93, Figs. 1, 6, which connect the gripping arms with the upper and lower runs of a chain 81, respectively. The chain 81 is supported on sprockets 82, 83 pivoted to a laterally slidable member 78 on which is mounted the cam 33. When the gripping arms move in opposite directions at the same speed the chain 81 merely runs round the sprockets and the cam is not moved. If the arms move in the same direction, or in opposite directions at different speeds, the slidable member 78 and the cam 33 are moved laterally. In a second embodiment, Fig. 11, the chain 81 is replaced by pinions 97 which are interconnected by pinions 98 and the rods 86, 93 are replaced by toothed racks 99, 100 which engage the pinions 97 to move a slider 74 and the cam 33 laterally. Fig. 12 shows a third embodiment in which a lazy-tongs linkage 101 provides the connection between the gripping arms and a slider 74 and the cam 33. In Fig. 13, a lever 106 is supported by cables 112, 114 attached to the gripping arms and to a plate 64. The lever 106 carries mercury switches 109, 110 and is urged downwards by a spring 111. Movement of the arms in opposite directions at the same speed moves the lever 106 up and down. Movement in the same direction tilts the lever, closes one of the mercury switches, and energizes one of solenoids 116, 117 to close one of the ball check valves. In addition one of horns 119, 121 is sounded and one of warning lights 118, 120 is lit. The other embodiments may also incorporate audible and visible signals by using limit switches.

Title: Improvements in and relating to photographic pigment printing
IPC: G03C1/66
Filed: 1924-03-05
Abstract: 234,902. Farmer, E. H. March 5, 1924. Drawings to Specification. Con,tact processes. - A tissue for use in processes of the kind in which a laver of pigmented gelatin is differentially hardened by contact with a silver print when immersed in hot water in the presence of certain re-agents (for example the " Carbro " process) comprises a layer of gelatin, preferably very thin, mixed with two or more pigments having dissimilar chemical properties or solubilities, and coated preferably upon a semitransparent support such as parchment paper, tracing paper, or ordinary paper treated with wax. The pigments may be chrome yellow which is soluble in acid but not in alkali, and prussian blue which exhibits the reverse solubility. A short treatment of a print in such a layer (a) with an acid bath yields a print having blue high lights and green dark tones, and (b) with an alkaline bath yields a print having yellow high lights and green dark tones. If the contact reaction is terminated when the silver in the dark tones is still dark grey, as observed through the translucent base of the tissue, and the pigment print is developed, and treated to modify the colours, upon the silver print as support, the residual silver image, which may subsequently be toned, strengthens the dark parts of the composite colour print. The gelatin of the layer may be mixed, before coating, with a quantity of a hardening agent, such as tannic acid, aluminium sulphate, or chrome alum, determined by the solubility of the gelatin.
Patent GB-1601235-A (GB)
Title: Method and apparatus for detecting ground shorts in electrical systems
IPC: H02H3/17
Filed: 1978-02-13
Abstract: In earth fault protection for a generator in unit connection by measuring the voltage between the star point of the generator and earth, the star point additionally being loaded with an operating-frequency displacement voltage, the problem is that the displacement voltage has to have high amplitudes for the earth fault current detection because of the operating-frequency interference voltages which necessitate that the sensitivity is set comparatively low. To obtain a useful current (Iv) allocated to the displacement voltage (Uv), which is representative of an earth fault, from interference currents (Is) of any type within certain limits and also of operating frequency, the vector of the displacement voltage (Uv) is switched to and fro between two positions (Uv1, Uv2) in the sense of a phase oscillation. The corresponding useful currents (Iv1, Iv2) can be detected with a large signal/noise ratio by phase-selective demodulation or rectification by means of a multiplier (11), which is supplied with the measurement current and a signal corresponding to the phase modulated displacement voltage (Uv). <IMAGE>

Abstract: 373,307. Circular knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Gagne, A. ; Central Falls, Rhode Island, U.S.A.) March 5, 1931, No. 6865. Convention date, March 19, 1930. [Class 74 (ii).] Relates to means for use in splicing stockings &c., functioning either to guide a withdrawn yarn to the cutter and binder or to cause an intermittently withdrawn yarn to avoid the cutter &c. and consequently to float. When a yarn lever 51 is elevated, the length of yarn passing to the last needle 52 taking yarn from it extends, as the needle reaches position 53, under a projection 43<1>, as shown in dotted lines. It is thus brought down into contact with the teeth of a loose plate 44 resting on the fabric. When the last needle gets to position 54 the yarn passes between cutting blades and under the clamping arm. When the pattern mechanism elevates the lever arm 17 to clamp and sever the yarn it also elevates plate 44 and brings it to rest by engagement with the arm 43. During knitting of a high splice or double sole, the plate 44 remains in elevated position a nd the floats 43 pass beneath it, being prevented by the arm 43 from rising above the binder plate 9. Specification 20101/09, [Class 74 (ii), Knitting &c.], is referred to.
