Title: Method of preparing a bituminous binder and a construction material containing the same
IPC: E01C7/26
Filed: 1975-09-12
Abstract: In a hot-mixing unit, bitumen is homogenised together with polyethylene and/or polypropylene to give a homogeneous binder for as long as necessary for the initial viscosity of the binder to drop significantly. Only the drop in viscosity beyond the usual drop in viscosity with increasing temperature is taken into account here. If the process is continued for a sufficient time, the viscosity of the binder composition is lowered so much that a road surfacing material produced using a binder composition of this type can be installed in a conventional manner intended for the processing of bituminous road surfacing materials. This allows the use of conventional methods and machines for installing the road surfacing material.

Title: Data transmission systems
IPC: H04B1/707
Filed: 1971-08-12
Abstract: 1497859 Multiplexing SIEMENS AG 12 Aug 1971 [6 Nov 1970] 37983/71 Heading H4M In a data transmission system using time division multiplex or code division multiplex techniques, at the commencement of a transmission an initial synchronization arrangement in the receiver constantly attempts to establish a code synchronization with the signal to be received, prior to switchover to normal synchronization. To this end the transmitter radiates a frequency jump modulated signal in which each frequency element is subjected to digital phase modulation, while the receiver produces an identical frequency jump and phase jump modulated signal with which the received signal from the transmitter is multiplied. The receiver-generated signal has its modulation phase repeatedly shifted until a maximum power output is obtained in a narrow frequency band at the multiplier output. The start of phase synchronism is derived from this criterion which is used to initiate switch-over to the normal operation of the receiver synchronizing devices. The Figure shown illustrates the arrangement of the invention, which replaces the initial synchronization circuit (15) in the known receiver of Fig. I (not shown) although some other elements of the known receiver are duplicated in the Figure. The transmitter is of similar, but slightly different, construction.

Title: Improvements relating to waste disposal units
IPC: E03C1/266
Filed: 1965-09-06
Abstract: 1,117,393. Waste-disposal apparatus; extrusion filter. SOMAT CORPORATION. 6 Sept., 1965 [8 Sept., 1964], No. 38000/65. Headings B1D and B2A. A unit for comminuting waste food, plastics, string, cardboard &c., comprises a tank 20, Fig. 3, a motor-driven disk impeller 21 having fixed cutting teeth 22 on part or all of its upper surface and a tubular sieve 23 encircling the impeller. The sieve has a wear ring 26 forming a peripheral flange of the ring-shaped sieve and extending to form with a head 27 the bottom of the tank 20. The sieve has slots or holes 28 to permit the flow of water and disintegrated material, whilst preventing passage of objects likely to trap an extractor 49. A slurry outlet 44 connects the sieve with a pulp discharge cylinder 47, which supports the inclined hydro-extractor assembly 49. The screw 53 of the extractor is rotated by a motor 57. In operation, material is inserted in the feed tray 65, whence it falls into the tank 21. Fresh water is supplied, the water level being automatically controlled. Material disintegrated in the tank forms a slurry which is raised by rotation of a screw 53, liquid being squeezed out through a screen 48 and returned to the unit via an opening 70 and a baffle 72. At the upper end of the extractor screw is a cutter 59 which cuts up the plug of material in the screw, so that it may be discharged. The cutter is adjustable so that when lowered in the tube, wetter material is discharged. Brushes on the undersurface 55a of the flights 55 of the screw bush the screen 48 and prevent clogging of the holes. Baffles 62 in the head of the tank 20 give a return action to the material being thrown outward by the impeller. A modified form of sieve and impeller are described, having adjustable cutting ears and a cutter ring together with a further rotatable disk having lugs which generate a pumping action tending to force material through the holes in the sieve. The cutting ears are adjusted so as to cover all the holes in the sieve, during rotation. Ears 61, Fig. 5, on the impeller wipe over the sieve 23 and also serve to pump the slurry.

Filed: 1968-08-08
Abstract: 1,272,771. Riveting. AVDEL Ltd. 4 Aug., 1969 [8 Aug., 1968], No. 38000/68. Heading B3U. [Also in Division F2] A fastener placing tool comprises a threaded draw bolt 38 for engaging a threaded part 31 of the fastener and which is rotatable and reciprocable with respect to a housing 37, an abutment 39 displaceable with respect to the housing 37 upon engagement with the fastener during the setting operation to cause the draw bolt 38 to stop rotating and to retract so as to set the fastener and a spring loaded detent 76 for positively retaining the abutment 39 in its displaced position. The tool is adapted to be connected to a drive shaft 25 of a pneumatic rotary motor unit (Fig. 1, not shown) having an overload clutch (24). The shaft 25 is rotated clockwise to rotate a tube 47 which transmits drive through a frictional drive 60, provided by a spring steel clip (63) (Fig. 6, not shown), to the draw bolt 38 and the attached nose assembly 39. The draw bolt 38 is inserted into the fastener so that it is screwed into the nut portion 31 until an anvil face 72 of the nose assembly 39 abuts the fastener. Thereafter, the nose assembly 39 is moved rearwards with respect to the housing 37, the detent pin 76 moving from a groove 82 to an adjacent groove 81 to cause dogs 73 on the nose assembly 39 to engage between dogs 74 on the housing 37. The nose assembly 39 is keyed to the draw bolt 38 by keys 83, 84 so that upon engagement of the dog clutch 73, 74, the nose assembly 39 and also the draw bolt 38 are prevented from rotating and the friction drive 60 is overcome. The draw bolt 38 is thereby retracted by the consequent relative rotation between a nut 59 secured to the rotating tube 47 and a threaded portion 58 of the draw bolt 38. The fastener is sheared at 34 and the nut portion 31 pulled into a tubular portion 33 until the resistance to retraction of the draw bolt 38 is so high that the pre-set torque clutch (24) slips to stop rotation of the drive shaft 25. The draw bolt 38 is then moved forward and rotated in a counter clockwise direction to unscrew it from the set fastener.

Abstract: 1387084 Transparency mounts S G PETTERSSON 10 Aug 1973 [17 Aug 1972] 38002/73 Heading G2X A transparency mount comprises two halves 1, 2, each having a thin portion (3, 7) in which is formed a rectangular opening displaced towards one end, and a thicker shoulder portion (5, 9) at one edge. The transparency 14 is located between the shoulder portions of the two halves, which fit together as shown, and are secured together by means of pins 11 on the half 1 which pass through corresponding holes in half 2, the ends of the pins then being rivetted over. Fig 6 shows a machine for automatically mounting the transparencies. These are fed into the machine in the form of a continuous film strip 23. The frame units 20, with the two halves already loosely assembled together are supplied in a magazine formed by angle rails 26, from which they are fed forward one at a time to the mounting station. At this station a pressure shoe 35, having an oblique lower side, is mounted for vertical movement. When it is lowered, this oblique side engages against the upper face of the shoulder 9 on the upper frame half, and tilts it upwards, as seen in Fig 11. While the two frame halves are thus opened apart, the film strip 23 is fed into it, and one frame 14 thereof is cut-off by a knife 31. Shoe 35 is now raised again, so allowing the upper frame half to pivot back into the closed position again. A vertically movable body 40 carrying a number of rivetting tools 41 (see also Fig. 10 not shown) is now brought downwards, the tools 41 engaging the tops of the pins 11 and rivetting them over, so that the slide unit formed by the transparency and the mount is permanently closed and finished. The completed unit 45 is now discharged from the machine.

Abstract: 985,341. Power assisted steering. INTERNATIONAL HARVESTER CO. Oct. 10, 1962 [Oct. 12, 1961], No. 38330/62. Heading B7H. [Also in Division G3] Relative rotation between a rotary cylindrical valve 33 and a sleeve 32 is damped by pistons 46 coacting with cams 48 in the sleeve so that movement of the valve in either direction from a neutral position causes inward movement of the pistons to compress fluid trapped in a bore 45 by a check valve 53. The fluid can escape slowly past the clearance between the pistons and the bore 45. The arrangement is suitable for preventing " shimmy " in hydraulically-assisted aircraft or marine craft controls or vehicle steering gear in which the valve is actuated by the steering wheel and the sleeve has a mechanical follow-up connection 19 with the steered wheels. A pin and slot connection 42, 55 allows direct manual operation of the steering should the displacement of the valve relative to the sleeve exceed a certain amount. In the neutral position of the parts holes 57, 58 in the sleeve, communicating through grooves 37, 39 in the housing 31 with ports 36, 38 leading to opposite ends of the steering motor, are connected with a fluidpressure supply port 34 through a groove 35, holes 56 in the sleeve and longitudinal channels 43 in the valve, and with an exhaust port 40 through a groove 41, hole 59 in the sleeve and longitudinal channels 44 in the valve, but movement of the valve in either direction causes one of the holes 57, 58 to be connected solely to the pressure supply and the other to exhaust. The check valve 53, which is permanently connected to the supply through a groove 43a, may be replaced or supplemented by a restricted orifice.
