Patent GB-274341-A (GB)
Abstract: 274,341. CalgÚer, W. Dec. 4, 1926. Clock-driven indicators.-Apparatus for indicating the times of arrival and departure of trains at and from railway stations comprises a board 1 for five railway lines a - - e, Fig. 1; for each line there is an arrival indicator Aa &c., and a departure indicator Da &c., the indicators having the general appearance of clocks; 2 is an ordinary secondary clock which is synchronized from a master clock which controls the step by step movement of the indicator hands. Fig. 2 shows the indicator construction, the successive arrival (or departure) times being marked on glass discs 4 set in the non-transparent face 3. Each disc is backed by a separate compartment containing a lamp 7 for illuminating the disc at night, controlled by contact 12 and wiper 11 rigid with the hand 10. The step by step movement of the hand 10 from one disc 4 to the next is effected from an electric time switching device; a worm wheel 14, driven from the master clock 13 one revolution in two hours, rotates a shaft 15 having ten ratchets 16, Figs. 3 and 4, having staggered teeth so that ten sets of contacts 17 are closed successively once a minute. Contacts 17 remain closed fifteen seconds. Geared to the shaft 15 so as to rotate once in twenty-four hours is the shaft 19 of a drum 20. This drum has five sections 20<a>, 20<b> &c., one for each railway line, and each section has ten peripheral rows 22, each row having a hundred and forty-four holes which are screw-threaded to receive studs 24, 23. The rows are staggered by <1>/10 th of the pitch of the holes. There is one short stud 24 and one long stud 23 for each row, and these studs are set in the row to correspond with the time of arrival (or departuure) of the train. Studs 24 closes contacts I and II, Fig. 5, and stud 23 closes contacts I, II, and III. In this manner the switches 17 and 21 selectively control electric circuits so that at the time a train is due to arrive on a particular line, an impulse from the master clock is transmitted to the appropriate indicator, the hand of which is moved on one step to show the time of arrival of the next train. The discs 4 may be differently coloured to distinguish fast from slow trains.

Title: Improvements in and relating to the glazing of bricks, tiles and the like
IPC: B28B11/04
Filed: 1935-10-10
Abstract: Relates to a machine of the kind described in Specification 437,968 for glazing bricks, tiles, or the like, and in which the glaze is maintained in a state of continuous flow by being circulated through a series of receptacles and pipes.  According to the invention, the receptacles have downwardly converging sides in order to prevent settlement of the solids suspended in the glaze.  The glaze reservoir 10 has a converging lower part 11 which merges into a pipe 16, and this pipe leads to a container 17 the lower walls of which converge to a mouthpiece 20.  The glaze flows from the moutpiece <PICT:0445170/III/1> on to the bricks which are supported on a conveyer 21, and any surplus glaze falls into a trough 22 from which it flows into a receptacle 24, also with converging sides.  A pump 30 returns the glaze to the reservoir 10.

Title: Loading device for mine galleries

Abstract: 694,199. Conveyers etc.; loading &c. GROETSCHEL, K. M. Nov. 17, 1950. [Oct. 1, 1948] No. 28163/50. Classes 78 (i) and 78 (iv). Nov. 17, 1950. [Oct. 1, In a loading device for underground gallery mining having a scooping or scraping loading tool for feeding material from a heap to a conveyer, the loading tool and its driving means is suspended above the bottom of the gallery from a rail or the like fixed to the gallery roof in such a manner that said mechanism is slidable along said rail or the like longitudinally of the gallery. The conveyer 30 has its lower feed end disposed below the floor of the mine gallery in a trench 31, and its upper discharge end is suspended by a cable from a carriage carried on an overhead rail 8 in the gallery roof. Coal is fed from a heap by a reciprocating scoop 5 onto the conveyer 30 which discharges it into trucks. Scoop 5 is pivotally mounted at 32 to a crosshead 4 attached to the pistons of two side-byside cylinders 2 forming part of a frame which rests at one end by means of rollers 7 on a horizontal U-shaped rail 6 arranged with the limbs of the U pointing towards the material to be loaded, and is suspended by cables towards its other end from a carriage 9 travelling on the rail 8. The scoop 5 is also pivotally attached by arms 18 to a cylinder 17 whose piston rod 20 is supported at the remote end 21 on the frame. Each cable bv which the frame is suspended is attached to the frame at 13, passed around a pulley 10 on the carriage 9, and a pulley 11 on the frame, and wound on a motor driven winch 12 mounted on the frame. A flap 29 of substantially the same area as the mouth of the scoop is pivotally mounted for movement within the scoop on a shaft 28 journaled in the scoop, and a pair of arms 26 carrying rollers 27 are mounted on the ends of shaft 28. In operation, the end supported on rail 6 is moved along the rail 6 to manoeuvre the frame into any desired position, whereby the scoop can operate forwardly or to either side of the gallery. The frame is then raised by means of winch 12 and the scoop is protracted forwardly by extending the piston rods of cylinders 2 and 17 to the chain line position, Fig. 3, and the frame is then lowered by the winch until the scoop touches the top of the pile of material. The pistons of cylinders 2 are then retracted somewhat while holding the piston of cylinder 17 in position, causing the scoop to dig into the pile of material, after which all the pistons are retracted simultaneously so that material is pushed by the scoop onto the conveyer. Towards the end of this movement rollers 27 engage stops 25 on the frame causing the flap 29 to discharge the material from the scoop onto the conveyer. Stops, not shown, are provided for limiting the forward protraction of'the scoop to suit the width of the gallery.

Abstract: 852,541. Electric tests. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 18, 1958 [Sept. 6, 1957], No. 28206/57. Class 37 In apparatus for gauging the thickness of a material such as a zinc coating, the " Q " factor of an inductive circuit positioned at a predetermined distance from the surface of the coating is detected. Fig. 1 shows a coil wound on a core and the central limb of which is spaced from the plate 4 to be gauged. In Fig. 4 this coil is shown as 21 which, with capacitor C1, constitutes the toned circuit of transistor TR1 the negative resistance characters two of which produces oscillations. The amplitude of the oscillations is controlled by the " Q " of the inductive circuit which is said to be dependent on coating thickness. The voltage developed at the emitter load is amplified by TR2 and is of sufficient amplitude to prevent a multivibrator TR3, TR4, capable of producing an audible tone, from operating. If the oscillator out-put falls the audible tone is heard in an earpiece. Fig. 2 shows the arrangement in which all the elements except the earphones are mounted in the exploded assembly shown. A brass face-plate 8 is provided with free rolling ballswhich space the assembly from the work under test. Inside head 10 is the core assembly 14 while the electronic circuit is mounted in aluminium tube 6 on a tay board 16. Batteries 17 are mounted on a "Perspex" (Registered Trade Mark) block. A switch is provided on the end of tube 6 and a flexible lead connects the assembly to the earpiece.

Recording apparatus for television signals comprises magnetic tape 11 wound on cylinder 12 within which is rotated a support 6 for the recording head. The support 6 is driven by an electric motor 10 which also drives conductive disc 1 having aperture 2 co-operating with lamp 3 and photo-resistor 4. The pulses produced from the photo-resistor are passed to a shaper 13 after which they are applied to stage 14. If the frequencies of raster synchronizing pulses R and of the light-pulses are equal, the frequency-comparison stage 14 applies the pulses to a phase-comparison stage 15 which measures the phase difference between the two pulses.
