Title: A process for making light-coloured bituminous road constructions and pavements
IPC: C08K3/08
Filed: 1935-02-11
Abstract: Light coloured road and pavement construction, such as road coverings, floors, traffic lines and joint and crack fillings, are made by applying a mixture of bitumen, mineral aggregate and aluminium powder to form a wearing course of the required thickness. Tiles, plates and blocks for road construction, traffic lines &c., may be provided with a top layer of the required thickness of the composition of bitumen, aggregate and aluminium powder.  The aluminium powder may be about 2 per cent of the weight of the whole mixture or 30 per cent of the weight of the bitumen.  Specification 212,106, [Class 22], is referred to.

Title: Improvements in or relating to the overload protection of electric motors
IPC: H02H7/085
Filed: 1951-02-23
Abstract: 704,977. Control of motors. BOOTH, S. Nov. 22, 1951 [Feb. 23, 1951], No. 4481/51. Class 38(3) An overload relay for a compound wound D.C. motor has a series coil 4 and an auxiliary coil 5 which is connected to a switch 7 controlled by a discriminating relay winding 8. When the speed of the motor increases, with a consequent increase of back-electromotive force, the switch 7 closes to energize the winding 5 so that the trip circuit is opened at a lower overload current than that for the starting period. In a modification, Fig. 2 (not shown), the coil of the discriminating relay is in series with the motor armature, and the auxiliary winding of the overload relay is shunted thereacross. The contact of the discriminating relay is open during the starting period and is closed to bring the auxiliary coil into operation when the current falls as the working speed is reached. In another arrangement two of the main conductors 33, 34, for a three-phase motor incorporates normal overload coils 35, 36, whilst the third conductor 37 includes a winding 38 of a discriminating relay. Auxiliary overload coils 40, 41, are connected in series with a centrifugal switch 42 which is manually closed for starting and automatically opened at a predetermined speed just below the normal running value. An alternative circuit for the coils 40, 41, is completed through resistance 43 and switch 39 which is operated by winding 38. During starting, the coils 40, 41, oppose the coils 35, 36, so that the motor can take a higher starting current. When the centrifugal switch 42 opens, the excitation of the coils 40, 41, is reduced by the resistor 43. Upon further reduction of current, the contact 39 opens to disconnect the coils 40, 41. The switch 42 may, be replaced by a push button which is held closed for starting.

Apparatus for classifying solid particles comprises a swirling chamber b in which the unclassified particles are mixed with and given a rotary motion by air supplied to the chamber through a tangential inlet c, an accelerator duct g and a diffuser h defined by the space between an outer conical casing i and an inner coaxial conical core k through which space the discharge from the chamber b passes in a spiral path and is separated at the outlet q of the diffuser into fine and coarse particles collected respectively in a funnel r opening into a pipe p and in a chamber m leading to a shoot n. The unclassified material is fed to the chamber b through a shoot a and an admission tube d having mixing slots e or deflectors f. The core k is part of a double-coned core mounted in a stationary casing and carried by a hollow spindle t1 slidable on a spindle t2 attached to the funnel r which is slidable in the pipe p. The core and the funnel r can each be raised or lowered by means of hand wheels u1 and u2 respectively to control the degree of classification which may also be varied by admitting external air through a circumferential slot s formed in the casing wall i and controlled by a ring-shaped valve element having adjusting screws v. The finer particles issuing from the pipe p may be separated from the entraining air in a separate separator (not shown). In a modification, Fig. 2 (not shown), the funnel r is modified to form a cyclone separator from which the fine particles are discharged through the pipe p and the air is exhausted through a central pipe extending upwards through the diffuser and the swirling chamber b.

Abstract: 935,772. Roller conveyers. HERBERT MORRIS Ltd. April 11, 1962 [Feb. 10, 1961], No. 5034/61. Class 78 (1). Apparatus for aligning and feeding lengths of rail longitudinally in end-to-end relationship to a welding machine incorporates a main conveyer 1 having rollers 3 with a set of cross-conveyers 4 and a set of pusher dog conveyers 5. Rails are deposited across the cross-conveyers 4 and pusher dog conveyers 5 at a position 26. The cross-conveyers 4 move more slowly than the pusher dog conveyers 5 dogs 6 of which engage the last rail of the batch at position 26 and move the batch to a reservoir position 27, across the cross-conveyers 4, where transfer trolleys 8 are stationed. When the first rail of the batch reaches the trolleys 8 a limit switch (not shown) is operated to reverse the direction of the pusher dog conveyer to return to position 26, dogs 6 being pivoted at 7 to pass under a fresh batch of rails at position 26. The rails in the reservoir 27 are moved forwardly by the cross-conveyers 4 until the leading rail is engaged by clamping means 11 on the transfer trolleys 8. When a rail on the main conveyer 1 reaches the end of the main conveyer it actuates a sequence means (not shown) causing guide rollers 15 on the main conveyer to swing down below the conveying level, clamping means 11 to grip the rail on the trolleys 8, the trolleys 8 to move along a guideway 10 until the web of the rail comes into contact with a set of guide rollers 13 mounted on fixed vertical axes, the guide rollers 15 to resume their initial position so that the web of the rail is guided between roller sets 13, 15 while the base of the rail rests on the main conveyer rollers 3. The clamping means 11 is released, the trolleys 8 return to their starting position and the cycle repeats. The main, cross and dog conveyers are driven by electric motors 20, 22, 24, the transfer operation being pneumatically operated by a cylinder 17 acting on the rollers 15 and a cylinder 19 acting on the trolleys 8.
