Title: Improvements in or relating to drilling machines with combined rotary and impact action
IPC: E21B6/00
Filed: 1951-08-07
Abstract: 719,223. Percussive drills. WALLRAM HARTMETALL GES. Aug. 7, 1951, [Aug. 7, 1950.] No. 18578/51. Class 124. A rotary and percussive drilling machine comprises means for rotating a drill spindle at a slow speed, means for imparting impacts to the spindle at a rate of more than 40 per minute, and feed mechanism for advancing the drill. As shown a spindle 5 carrying a drilling tool and which is rotatably driven by a motor, has fixed to it a flange 1 having two rings 11 and 12 each of 20 rollers. A sleeve 2 carrying four pairs of rollers is axially slidable on a spindle carrying the flange 1 and a sleeve 3 also carrying four pairs of rollers is slidable on the sleeve 3, the rollers on sleeve 3 being staggered with respect to those on sleeve 2. On rotation of the flange 1 and the spindle 5 the rollers on the flange will run upon a pair of rollers on the sleeves and the latter will be urged forward to produce an impact on an impact plate 4. The percussive action of the drill may also be obtained by magneto striction. The drill may be mounted in a cradle 27 attached to a nut 37 which co-acts with a feed screw spindle 34 rotated by a motor 33 to move the cradle forwardly. The forward part of the drill steel may be supported in bearings 25-26 carried by a guide holder 24 and in which it is capable of axial movement.

Title: Terminal strip for the cover of an electrical appliance
IPC: H01R9/00
Filed: 1978-05-09
Abstract: Connecting strips, which consist of flat plugs (18) and covering strips (24), are arranged on the lateral sides of the cover (12) of a time-switching relay. The covering strips (24) consist of transparent insulating material and enclose the flat plugs (18) in their centre part. Each flat plug (18) is equipped with plug contacts (22) which project outwards at an angle. An electric-shock protection edge (30) extends upwards from the covering strip (24), parallel to the plug contacts (22). The electric-shock protection edge (30) extends considerably beyond the end of the plug contacts (22). This construction results in it not being possible readily to plug connecting leads incorrectly onto the plug contacts (22), and in the electric-shock protection being achieved not by the cover (12) itself but by the electric-shock protection edge (30) of the covering strip (24). <IMAGE>

Title: Improvements in remote indicating systems responsive to speed of rotation
IPC: G01P3/20
Filed: 1943-11-11
Abstract: 578,560. Servomotors. HULME, R. L. Nov. 11, 1943, No. 18789. [Class 135] [Also in Group XIX] A system of the kind, in which pressure or vacuum producing means are connected through a constricted orifice with one of two spaces on opposite sides of a valve, the difference of pressure tending to open the valve, whereas the actuating force tends to close it, the resulting difference of pressure producing a remote indication of the actuating force, is arranged to be responsive to speed of rotation, one of the said spaces being constituted by the interior of a bellows mounted for rotation, the axis of the bellows being at right angles to the axis of rotation. The body, whose angular speed is to be measured, drives a rotor 81 through gears 86, 87. An air supply is led from a pipe 103, a constriction 21 and a passage 102 to the inside 22a of the rotor. The end 39 of the bellows 12 is pressed by centrifugal force to a greater or less extent against a valve 38 so that the pressure on the outside of the bellows builds up until air leaks past the valve, when the speed of the rotor is indicated by a pressure gauge 26 connected to the interior of the rotor 81. The casing of the pressure gauge may be connected by an equalising pipe to the casing 79, especially if the speedometer is for use on an aircraft where local pressure differences may occur. Alternatively, double-beat valves may be used to eliminate the effect of atmospheric pressure. Instead of using a source of air-pressure, a source of suction may be used, 'the valve 38 being reversed. According to the Provisional Specification, the invention may be used to indicate the positions of the landing flaps on an aircraft, radiator temperature and other variables.

Title: Improvements in or relating to sewage effluent renovation
IPC: C02F1/52
Filed: 1966-04-29
Abstract: <PICT:1108834/C1/1> A process for treating sewage effluent comprises clarifying the effluent, filtering the clarified effluent, partially demineralizing the filtrate with a cation exchange material, treating it with active carbon and further demineralising it with an anion exchange material.  As shown, biologically oxidized sewage effluent may be clarified in the first step in an apparatus as shown in Specification 993,335, by treating it with a precipitant, e.g. lime, to precipitate a sludge, continuously re-cycling the sludge, adding further precipitant and untreated effluent to it at each recycle, adding a flocculant, e.g. ferrous sulphate to the recycled and newly precipitated sludge, and separating treated liquid therefrom.  The liquid is then passed through a sand filter 20, a primary cation exchanger 24, which preferably reduces its pH to from 2.0 to 3.0, and through a succession of carbon units 22-24, and a primary anion exchanger 25.  Further demineralization may be achieved by passage through a secondary cation exchanger 26 and a secondary anion exchanger 27.
