Title: Improvements in or relating to pipe cutting devices
IPC: B23D45/12
Filed: 1960-04-07
Abstract: 903,934. Milling-machines. FISCHER A.G., GEORG. April 7, 1960 [April 7, 1959], No. 12392/60. Class 83 (3). [Also in Group XXIII] A pipe-cutting device comprises a vice 1 for clamping the pipe 6, a body 11 mounted for manual rotation in a bearing 7 on the vice, a tool carriage 18 radially slidable in the body and a fixed disc 9 having a notch 22 in which a sliding shoe 24 normally rests so that the tool 37 is out of contact with the pipe but which rises on to the periphery of the disc as the body is rotated round the pipe so that the tool is fed through the pipe wall and maintained in this cutting position until the shoe again falls into the notch after a complete revolution. The tool 37 is driven from a motor 26 through spur and worm gearing and may be a saw or a grinding disc and may have milling cutters 64, Fig. 6, on one or both sides of it. The shoe 24 bears on a collar 25 of a spindle 20 screwed into the carriage and the initial position of the tool relative to the pipe may be adjusted by rotating the spindle. An end stop 47 for setting the length to be cut off is mounted on a shaft 46 adjustably clamped at 48 and spring-loaded jaws 61 prevent the cut-off length from falling. The direction of tool rotation is such that the teeth cut from the inside of the pipe to the outside and this direction is indicated by teeth 66 cast on a cover-plate 13. Air drawn in by the motor 26 is passed through holes 38 to cool the tool and blow away chips.

Title: Improvements in and relating to concrete mixing machines
IPC: B28C5/20
Filed: 1931-04-27
Abstract: 362,824. Concrete-mixing machines. WAGENER, T., 4, Marienburger Strasse, Marienburg, Cologne, Germany. April 27, 1931, No. 12420. Convention date, Aug. 26, 1930. [Class 86.] A machine for mixing concrete comprises a rotating drum into a compartment of which the dry materials are fed in batches, the dry mixture being discharged into another compartment where water is added and from which the complete mixture is continuously discharged. The dry materials are fed by buckets 13 discharging into a shoot 5 leading into the compartment a of the drum. The dry mixture is fed by a fixed or movable shoot 8, mounted on fixed bars 18, through a partition 7 into the compartment b where water is added by a pipe 9 and from which the complete mixture is discharged by a shoot 6.
Patent GB-906390-A (GB)
Title: Improvements in and relating to electrical systems for transmission of information to a distance
IPC: H04L27/12
Filed: 1959-04-13
Abstract: 906,390. Code telegraphy. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 13, 1959 [April 24, 1958], No. 12495/59. Class 40 (3). In a telegraph system in which the code impulse elements, i.e. the marks and spaces, or the " 1's " and " 0's " of a signal, are sent as different carrier frequencies over a transmission path, such as a telephone line, the carrier frequencies, which are arranged to be multiples of the fundamental frequency of the impulses, are determined in such manner that their difference is an even multiple of the fundamental impulse frequency, and that the changing over at the signal impulse frequency is effected at the instants at which the two carrier frequencies are equal in amplitude. In a preferred arrangement, Fig. 3 (not shown), the frequency changes by the impulses occur when the carriers both reach their maximum or minimum amplitudes. In the transmitting arrangement, Fig. 1, a basic frequency fm from a master oscillator 1 is divided in the chain 2 to provide a frequency fd which is further divided by a chain 3 to provide a frequency fi which is arranged to be twice the telegraph frequency, fd. The frequencies fm, fd are applied to a ring modulator 4 passing carrier frequencies to band-pass filters 5, 6, and to switching devices 8, 9 controlled according to the impulse elements from the code generator 10 to allow one or the other frequency to pass to a line 12. The difference between the carrier frequencies is equal to a multiple of the impulse frequency fi which itself is twice the telegraph signalling or fundamental frequency, fd. A network 7 is utilized to ensure the required phase relation of the two carrier frequencies, and the dephasing network 11 can be utilized to effect control so that the frequency change-over by impulses will only occur when both of the carrier frequencies have simultaneously reached their maximum amplitude or their minimum amplitude. In a modification, in which the chain 2 divides the frequency of the oscillator 1 by an even number, the modulator 4 and two band-pass filters 5, 6 are omitted, the carrier frequencies being taken directly from the outputs of the oscillator 1 and of the dividing chain 2.

Title: Improvements relating to low temperature carbonisation
IPC: C10B1/04
Filed: 1936-05-06
Abstract: A combined carbonizing, lime-burning, and electric furnace plant for obtaining calcium carbide, comprises a number of retorts charged with coal and limestone, and enclosed in a water jacket from which steam is obtained for generating electric current which is used in a furnace to which powdered lime and coke <PICT:0475033/III/1> <PICT:0475033/III/2> <PICT:0475033/III/3> <PICT:0475033/III/4> are fed from the retorts for the production o calcium carbide, the electrode for the furnace being made in a central retort.  A boiler 1 is provided with corrugated tubes 2 into which retorts 5, 6 and an electrode chamber 4 are inserted.  Gas from pipe 57 and air from openings 56, Fig. 6, supply heat to the flues 3, the retort door 58 being held in place by a pivoted arm 61.  Coal and limestone in retorts 5, 6 are converted into coke and lime which are discharged into hoppers 15, 16 feeding crushing rollers N, Fig. 2, through which are circulated feed water for the boiler. The powdered coke and lime are air borne through duct S to a container, the larger particles falling on to a conveyer 23.  The coke and lime powder are then fed through tubes 24, 28, in a water heater 25, and pass into an electric furnace 65 into which dips the electrode 7 which is fed downwardly by endless band grips 62. The hot gases evolved from the furnace pass upwardly through a perforated partition 33 and tubes 26 in the water heater 25, and are drawn off through pipe 66 for recovery of byeproducts before being burned in the tubes within the boiler 1.  A plug 40, on withdrawal, allows the molten carbide to flow on to a cooled circular table 46 on which it is divided into sections by a cutter 44.  A turbo-generator driven by the steam raised in the boiler provides a supply of electric current to sliding contacts 70. The furnace pan 29 is carried on arms 34 on a shaft 35 which is raised or lowered by a piston 36 in a hydraulic cylinder 37.  Two pans are arranged on the same shaft at an angle so that when one is in use the other may be cleaned.  The electrode 7 is made by heating a compacted mixture of powdered anthracite and coke in the central retort 4, and the current passes to a hollow electrode 32 through which the molten carbide flows.  The feed water for the water space 25 is heated by a water jacket on the electric furnace, an inlet 68 being connected to a water jacket on the carbide cutter.
