Title: Method of and apparatus for flame-piercing mineral materials and the like
IPC: E21B7/14
Filed: 1947-10-30
Abstract: 639,070. Burners. LINDE AIR PRODUCTS CO. Oct. 30, 1947, No. 28934. Convention date, Dec. 3, 1940. [Class 75 (i)] [Also in Groups XXI and XXII] - An oxy-acetylene blow-torch comprises a central acetylene-carrying bore 16 extending from a header 12 to a tip 11, the bore being surrounded by a sleeve 13 forming an annular chamber 20 for the passage of oxygen to the tip 11 from which it is discharged through a series of inwardly directed ports 21 to intersect the acetylene jet. A further sleeve 22 is rotably mounted concentrically with the sleeve 13 to form an annular passage 23 for carrying cooling fluid, e.g. water, which is discharged in a rearward direction from the tip through ports 34. In use, the oxy-acetylene flame melts the rock face aided by a flux, which may be carried in the acetylene jet, and the liquid slag flows rearwardly to be cooled and solidified into a friable mass which is then disintegrated by the reamer blades 38 attached to the rotatable sleeve 22, the disintegrated particles then being ejected from the hole by the combustion gases and steam generated during the cooling of the slag. The reamer blades may extend parallel to the longitudinal axis of the sleeve 22 or have the front portion inclined to said axis or be in the form of a spiral, whilst the cutting edges of the teeth may have tungsten carbide inserts or a layer of such material deposited on them. The blow-pipe is mounted on a carriage C in a manner which permits the sleeve to be rotated manually or by an electric motor Mb, the oxy-acetyline pipes 13, 16 remaining stationary due to the flexible hoses W, O, N. The carriage C and hence the blowpipe, is advanced towards the rock face by a hand- or motor-operated screw 62, the carriage moving over rails 60 formed on the head A of a tripod T. Surrounding the bore hole is a cowl H with a water spray 124, the detritus being carried back through trunking K to a separator S in which the entrained solid particles are separated from the gases.

Title: Ringer blocking circuit for telephones
IPC: H04M11/00
Filed: 1974-07-01
Abstract: 1477736 Substation apparatus INTERNATIONAL MOBILE .MACHINES CORP 1 July 1974 29035/74 Heading H4K A substation includes means to intercept an incoming ringing signal and to allow the ringing signals to actuate the bell only upon reception of a predetermined code from the caller. As described the invention is applied to a system in which ringing signals are transmitted over a third line wire. The ringing signal initiates operation of .a timer which via an AND gate actuates a relay controlling the bell if the other input to the gate is enabled in response to a three digit multi-frequency code received from the caller over the speech path within a predetermined time. Prior to reception of the code a dummy ringer may be connected into circuit. Additional codes may be recognized to control lamps, ovens, radios, alarms &c.

Title: Improvements in and relating to reversible inward radial flow turbines
IPC: F02C7/00
Filed: 1955-10-12
Abstract: 801,101. Turbines. FUR TECHNISCHE STUDIEN A.G. Oct. 12, 1955 [Oct. 13, 1954], No. 29114/55. Class 110 (3). A reversible inward radial flow turbine has two axially - adjacent, oppositely - extending spiral inlet chambers, designed to impart relatively reverse swirling motions to working medium fed through them selectively to the turbine rotor, which discharge through annular nozzles into a common annular entrance chamber which encircles the periphery of the rotor. The runner 2 having radial blades 3 is mounted on a shaft 4 supported in a housing 1 by a bearing 5. Working medium supplied through a duct 6 may be guided by a pivoted vane 10 into either of the spiral inlet chambers 8, 9. The chambers 8, 9 discharge through ducts 12, 16 containing guide blades 13, 15 into an annular chamber 14 located before the runner. Since the spiral inlet chambers 8, 9 extend in opposite directions, the external dimensions of the housing 1 remain substantially constant over the whole periphery. In a modification, the inlets of the spiral chambers are arranged tangentially and at 180 degrees to one another. In this arrangement, the guide blades may be omitted. In a further modification, the division wall between the chambers is arranged in a plane perpendicular to the turbine axis and the outer axial boundaries of the housing are then formed as helical surfaces. In this arrangement, the common annular chamber 14 is provided with an axially sliding wedgeshaped member to improve the flow conditions into the turbine.

[Class 81 (ii)] An appliance for treatment of an ectopic testicle comprises a ring adapted to be placed around the scrotum above the testicle to retain this in the correct position into which it has been brought by manipulation, and traction means attached to the ring to exert a downward pull. Further means exerting an upward pull may be fitted for safety. The traction means may comprise adjustable straps 2, 3 (Fig. 1) attached to a belt 5. The ring may be either flexible or rigid and placed over the scrotum by being either stretched or opened. It may be a hole 1 in the material of the straps where these are elastic (Fig. 1) or formed by clamping two of the straps together by an adjustable clamp 41 (Fig. 8). Another form has an inflatable perimeter whereby the size can be adjusted. A non-circular and particularly an indented shape (Fig. 8) is particularly advantageous in accommodating the scrotum. Fig. 14 shows a rigid ring 42 with interior adjustable studs 44 producing the indented outline.

Colour kinematography. - Light of two or more colours of the spectrum acting successively is caused, during still or kinematographic photography or projection, to sweep over the film or lens, or to intersect the image beam. As shown in Fig. 1, light from a source b passes through a condenser c, a slot d, and a prism a, to form a spectrum falling on the lens f of a kinematograph camera or projector, and the prism is oscillated in synchronism with the shutter to cause the spectrum to sweep completely across the lens during one, two, or more exposures. The spectrum may, alternatively, sweep across the film, and its light source may be the same as that falling directly on the film. Fig. 2 shows lamps h in casings k permitting light to pass between parallel transparent reflectors o between the components p, q of the lens of a camera or projector. Glass cylinders j stained with some or all the colours of the spectrum are rotated in synchronism with the shutter. The transparent reflectors &c. may be placed between the lens and film, or between the lens and object.
