Patent GB-536187-A (GB)
Abstract: 536,187. Wash fountains. THORNTON, A. A. (Bradley Washfountain Co.) March 6, 1940. No. 4207. [Class 69 (i)] [Also in Group I] A washfountain comprises a basin and a water supply conduit extending upwardly through the drain passage to distributing means above the basin, the conduit being separated from the drain passage by a spaced member which leads leakage from said passage direct to atmosphere. In Fig. 1, the basin 10 has a tubular member 12 provided with drain openings 13 and seated on a spud 14 threaded to a drain fitting 17 provided with a threaded boss 25 supporting an elbow fitting 28 ; hot and cold water connections 32,33 lead through a mixing valve 31 to the fitting 28, from which the water passes through pipe 30 to a spray head 16. A pipe 24 is threaded at 23 to the fitting 17 and is spaced from the pipe 30 so that drainage water leaking into the pipe 24 passes to atmosphere. In Fig 5, the water first passes downwardly through pipe 40, and then by pipe 42, a foot-controlled valve, and pipes 43, 54, to the spray-head. In another form, the drain fitting 17 is associated with a trap from which a bent pipe passes upwardly through the water supply pipe, a manifold corresponding to elbow fitting 28, Fig, 1, being sweated to the vent pipe, or to a pipe between the vent and water supply pipes; a modification of this form is also described in which the water supply initially passes downwards as in Fig. 5.

A light-sensitive body is made dispersing CdS of size less than 1À5 Á in a thermosetting resin having a specific resistance by volume of at least 10 inches ohm cm., applying the dispersion to a support and heating the coated support to harden the resin. The photoconduc. tive layer may be used for electrophotography, photo cells, or image intensifiers or converters. Electrophotographic elements are made by mixing (20-60 volume per cent) CdS with resin with or without an organic solvent. The resin may be of the methacrylate, epoxy, phenol, amino, silicone, polyurethane, or cellulose type whilst polyesters or acetic acid vinyl chloride copolymer may also be used. The support may be paper, iron or aluminium and a thermosetting binding agent may be used.

Abstract: 1378489 Sludge granulation AMES CROSTA MILLS & CO Ltd 8 Nov 1971 [14 Nov 1970] 54296/70 Heading B5A [Also in Divisions B1 B2 and F4] Dewatered sludge cake is granulated by passage through a screw mixer-granulator, the granules are fed to a heated drying chamber and some of the dried and heated granules are recirculated to the granulating stage to assist in the breakdown of the cake and effect a measure of pre-heating. In the Fig. 1 embodiment, the sludge from dewatering units 10 is mixed with the hot granules in a screw mixer 16, passed to a granulator 15, and fed to an inclined air-pervious carrier 21 in a chamber heated to incandescence at one end 23 by one or more oil burners 44. Hot air from the top of the chamber is recirculated by ducts 35 to beneath the carrier 21 to heat and fluidize the bed of granules. Two weirs 25 and 22 restrict the flow of granules and effect a build-up so that a proportion can be by-passed by a screw 26, and re-circulated up the elevator 28, the remainder being burnt on the inclined grate. If desired all of the granules may be discharged in which case the burners must supply all of the heat for drying. In the Fig. 2 embodiment, cake is fed to a first screw 52 of a mixergranulator which breaks it up and conveys it to a second screw 55, where it is mixed with recirculated granules 57. The outlet from 55 terminates in a drying chamber in the form of an inclined rotatable drum 59 which discharges into a hopper 60. This hopper is fed with hot gas at 79 from a cumbustion chamber 66 so that these hot gases pass up the dryer and return to the combustion chamber, via ducts 81 and 83 and fan 82. The heated granules discharged into the hopper 60 are divided by a butterfly valve 61 into two streams: one stream 63 being recirculated by a screw conveyer 58 to the granulating screw 55 and the other 63 being passed up a feed elevator 65 into the combustion chamber 66. A by-pass outlet 67 is provided together with a flap-valve so that any desired proportion of granules may be discharged, e.g. for use as fertilizer, the remainder being burnt. The combustion chamber is oil-fired; ash is discharged from an outlet 78 and flue gases are removed to a cyclone 72, via a water spray 73, the scrubbed gases being vented through a chimney 75 and the ash recovered from the "U"-outlet 77.

The components 1, 2 are supported in pins 4, 5 rotatable about axes a 4 , a 5 , which are separated by a distance d which satisfies (r 1  - r 2 ) # d # (r 1  + r 2 ). The pins are fixed in their adjusted positions, e.g. dry soldering, welding, clamping or glueing, or by shrinking by cooling the previously warmed housing. The coupling losses between the fibres 1, 2 can be reduced by altering their refractive indices at their ends, e.g. by heating, and a reflection-reducing substance, e.g. an immersion oil, may fill the space between the ends. In a modification, adjustment is made by rotating only one pin about its axis of rotation, and the housing about the axis of rotation of the other pin which is held rigidly in the housing.

Abstract: 1372599 Keyboard data entry apparatus INTERNATIONAL BUSINESS MACHINES CORP 4 Dec 1972 [30 Dec 1971] 55852/71 Heading G4H Keyboard data entry apparatus comprises a signal generator 10-12 operated by depression of a key 28, Fig. 2, to send a signal to a switching circuit 40, an encoder 46 responsive to an output 45 from circuit 40 to produce an output data signal 48 and a signal 49 which is delayed and which disables the switching circuit so that, on depression of a key, a corresponding data output signal is produced only for a time period terminated by the occurrence of the delayed signal.  Depression of a key 28 effects a capacitive coupling between a drive pad 11 and a corresponding sense pad 12 formed as printed circuits on a substrate 14: an oscillator 10 sends a signal via an integrator 33, Fig. 3 (not shown), to a Schmitt trigger 39 which in turn sends a negative signal to AND-gate 41 in circuit 40. Gate 41 is enabled by this signal and the negative signal from a gate 42 to send a signal 45 to encoder 46 which outputs signals 48 and 49; signal 49 passes via a delay 50 to a gate 43 which sends a negative signal to enable gate 42 whose positive output disables gate 41. The data on one of lines 48 passes via a gate 66 to a latch 69 in a keyboard data register 67; if there is no data already stored therein, gates 52 and 57-80 ensure that a signal passes to a single shot 78 which then actuates a magnet and arma ture 75, 76 to produce an audible click as the data is stored. If data is already present in the latches then gate 53 co-operates with the above gates to produce a "keyboard register overrun" signal until the latches are cleared by a signal 70.

A lasting machine of the type in which a last is supported bottom down in the machine and is operated on by wipers which are mounted for limited universal movement so that the wipers conform to the contour of the bottom of the insole includes means for preventing the limited universal movement during the early part of the wiping stroke and until the wipers have commenced to wipe the lasting margin against the insole. As described the means for preventing limited universal movement is incorporated in the heel seat lasting section of the lasting machine described in Specification No. 1,158,743. The heel seat wipers 138 (Fig. 9) are mounted on a back-up plate 120 which can pivot about a longitudinal axis 124 with respect to a support plate 112. Springs 128 are interposed between the back-up plate 120 and the support plate 112 at either side of the longitudinal pivot 124. The support plate 112 can pivot about pins 110 (Fig. 4) on arms 92 fixed to an adjustment plate 74 and a spring 114 is interposed between the support plate 112 and the adjustment plate 74. Thus the back-up plate 120 and wipers can partake of limited universal movement with respect to the adjustment plate 74. During the early part of the wiping stroke the ends 153 of the wiper drive bar abuts lugs 162 (Fig. 11) mounted on bars 160 fixed to the arms 92 thus preventing movement about the pins 110 and the ends 153 also abut lugs 166 fixed to the support plate 112 thus preventing movement about the longitudinal pivot 124. As the wiper drive bar moves forwardly in its wiping stroke its ends 153 clear the lugs 162, 166 thus allowing the wipers to partake of limited universal movement. The bars 160 carrying the lugs 162 are adjustably mounted on the arms 92 by bolt 242 and slot 244 connections and the lugs 166 are similarly mounted on the support plate 112.
