Abstract: 881,312. Sawing. GIDLEY, R. June 23, 1960 [April 21, 1959; July 16, 1959], Nos. 13524/59 and 24400/59. Class 145. A power hacksaw has its saw frame 18 mounted for movement in a holder 22 which is connected by a post 23 to a piston in a jack 25 so that the saw can be fed into and out of the work 16 along a line perpendicular to the work; the saw blade 20 is the end portion of a coiled blade within a cassette 24 mounted on the saw frame 18. The frame 18 either slides in ways 21 in the holder 22 or is pivotably mounted at the centre of the holder and is given a reciprocating or a rocking motion by a crank 15 connected to a crank-pin 14 driven by a motor 5. The saw frame is lifted by hydraulic pressure from a pump 29 and may be pulled down by hydraulic pressure or allowed to fall subject to a controlled escape of pressure from the lifting side. The pump is operated by a rod 32 oscillated by a cam on a countershaft 10 and a triple action valve has one position for lifting the saw frame and two other positions between which it alternates during the working of the saw so that the saw is intermittently lifted from the work during the return stroke. For heavy work, the lifting and lowering means could be duplicated. The work is gripped by an arm 17 controlled by a screw-and-nut mechanism and hand wheel 33 or by a jack 35 to which constant-pressure fluid is supplied; the arm may be rotable out of the way of the work. Coolant from a tank 42 within the cylindrical base 2 may be supplied to slots 40 in a plate 39 which fills in the saw frame and passes into the kerf behind the saw.

Title: Improvements in and relating to air and gas compressors
IPC: F04B49/16
Filed: 1923-05-22
Abstract: 218,799. Bryant, C. W., and Brotherhood, Ltd., P. May 22, 1923. Regulating compression.-The actual or virtual volume of the clearance space of a compressor is regulated by means dependent on the speed or torque exerted to drive the compressor; an automatic relief valve may be provided in the discharge pipe. As shown, clearance vessels a, bare connected with the ends of the compressor cylinder c by ducts d, e controlled by piston valves f, h mounted on a spindle. which carries a piston k working in a cylinder m. Ports n, o at the ends of this cylinder are controlled by a pilot valve r, the casing of which is formed with an inlet duct s for air under pressure and outlets t, u to atmosphere. The main valve spindle i and the spindle w of the pilot valve are connected to one end and an intermediate point of a floating lever v, the other end of which is connected through a spring-controlled bell crank &c. with a speed governor x on the compressor crank shaft. Variation of the speed thus varies the throttling effect of the valves f, h. Alternatively, the actual clearance volume may be similarly controlled by valves admitting liquid, or by altering the position of a piston in the clearance vessel. The pilot valve may respond to variations in the torque, being operated, for example, from a coupling consisting of two discs with a spring-driving connection. The pressure in the discharge pipe may be regulated by a piston valve 4. Fig. 2, loaded by a spring or weight and controlling a passage 9 leading to atmosphere or to the compressor suction pipe.

Title: Improvements in apparatus for determining the direction of sources of sound
IPC: G01S1/72
Filed: 1931-05-07
Abstract: 363,600. Locating sounds. AKT.-GES. C. P. GOERZ OPTISCHE ANSTALT, Pressburg, Bratislava, Czecho-Slovakia. May 7, 1931, No. 13576. Convention date, May 17, 1930. [Class 118 (ii).] The indication given by a sound-direction determining device is corrected for the refractive effect caused by the variation of atmospheric temperature with altitude. The correction applied, which is a maximum when the sound source is in the horizontal direction and zero when it is vertically above the apparatus, is dependent upon the altitude of the source and upon the ground temperature. The altitude is accordingly independently determined or estimated. Three receivers 5 are attached to a support 4 which can be swung about a horizontal axis 3. Secured to the support 4 is a lever 6 having a pin 6a engaging a slotted link 7 pivoted at 8 on a lever 10 which is itself pivoted at 9 to the support 4. A pin 11 is pivoted in a forked part of the lever 10 and has rotatably but not slidably mounted in it a screw 12 the threaded part of which engages a part 7a of the link 7. A pointer 14 is also secured to the link 7. With the axis of the support 4 in the horizontal direction the link 7 is adjusted by the screw 12 an amount dependent on the altitude of the source or on the ground temperature or on both. The receivers are then swing about the axis 3 until the axis of the support 4 is in line with the direction of the incident sound. This direction is then indicated by a pointer 17 secured to the arm 6 and the corrected direction or direction of the source is indicated by a pointer 15 integral with the lever 10. The whole device is rotatable about the vertical axis of the stand. In a modification, the link 7 and screw 12 are dispensed with and an indicating point on the lever 6 is kept by the operator on one of a series of curves pivotally mounted on the lever 10.

Title: Improvements in the manufacture of composite glass webs
IPC: C03C27/12
Filed: 1964-04-02
Abstract: 1,027,853. Laminates. SPIEGELGLASWERKE GERMANIA A.G. April 2, 1964 [April 6, 1963], No. 13627/64. Heading B5N. [Also in Division E1] A method of making insulating glass panels consisting of two panes of glass held in spaced relationship to each other by a cast intermediate peripheral layer which defines a hermetically sealed air space between the plates comprises, casting on to one surface of a first pane 11, Fig. 5, between mould-defining strips, a peripheral layer 15, curing the layer, removing the mould-defining members, inverting the pane on to a larger second pane 14 to the edges of which is attached a detachable strip 17 which, together with the edges of pane 11 and layer 15, defines a mould, and casting a further layer 16 which, when cured, forms with layer 15 a unitary L-shaped frame. One mould-defining strip for the layer 15 may comprise a gaspervious foamed material 13 adhesive-coated on both edges and forming part of the finished product, its use permitting pane 14 to be superimposed over pane 11 before the cast strip 15 has cured, thereby obviating the soiling of the inner surface of pane 11. In another embodiment, the foregoing procedure is modified in that the first layer 15 is cast only to a thickness equal to half the gap between the panes, thus when panes 11 and 14 are superimposed the layer 15 together with the member 17 defines an L-shaped mould into which layer 16 is cast. This allows of a reduction in the amount by which the second pane is larger than the first. The preferred material for layers 15, 16 is an epoxy resin containing a curing agent, e.g. polyamine or polyamide and a plasticizer, and optionally fillers such as quartz powder or titanium dioxide. The mould-defining members may be of cellulose and adapted for heating.

Title: Improved record-player
IPC: G11B17/04
Filed: 1955-05-11
Abstract: 820,563. Phonographs. WINTER, P. E. May 11, 1956 [May 11, 1955], No. 13657/55. Class 40 (2). A transportable record-player for disc records comprises a case having an edge-wise slit 10 for insertion of a record, a pair of gripping members 11, 12 for supporting and positioning a record for rotation about its central axis and an actuating element adapted to be moved by the record to cause one of the gripping elements to be moved towards the other and hence grip the record between them. The member 12 is mounted for free rotation about a member 16 whilst the member 11 is carried by a shaft 13 which is slidably and rotatably mounted on a member 15, the member 11 being urged towards the member 12 by a spring-loaded bearing 17. The record is first lowered on to a roller 47 and then pressed downwardly so as to move a lever 20 and actuate a trigger 73. The trigger 73 applies a pull to a wire 71, thereby releasing a latch 42 to free the member 11. As the member 11 moves, a fork member 40 is swung about its pivot, thereby allowing a wire 33 to slacken sufficiently to permit the pick-up head 27 to engage the record under the action of a spring 32. Movement of the lever 20 also actuates the electric motor which is embedded in a mass of sponge rubber 49 and incorporates a rheostat control, the record being rotated through a roller 47 in frictional contact with its rim. At the end of the playing period an arm 53 is engaged by a counterweight 34 to switch off the power supply. A key 93 is depressed to withdraw the member 11 from the member 12 and pull the tone-arm 26 away from the record. Downward gravitational movement of the tone-arm causes upward movement of the counterweight 34 to release the arm 53 and allow the switches to return to the " on " positions. Withdrawal of the member 11 releases the record so that the lever 20 swings upwardly displacing the record into a withdrawal position. In a modification, Fig. 4 (not shown), the member 12 is replaced by two rollers and the member 11 is mounted on a lever pivoted about one end.

Abstract: 561,908. Automatic control systems for chemical processes. AMERICAN CYANAMID CO. Oct. 2, 1942, No. 13870. Convention date, Nov. 26, 1941. [Class 38 (iv)] [Also in Group III] The ion removal capacity of a material is automatically maintained within definite limits by automatic control apparatus responsive to the pH of a fluid after passing over the material. The apparatus comprises reservoirs 70, 71 of alkali 80, 81 of acid and 90, 91 of water, piped as shown in Fig. 2 to containers 11, 21 for the material and comprising spring closed valves adapted to be opened electrically. The effluent from the containers 11, 21 may pass to glass- and reference-electrode cells 10, 20 for measuring its pH after passing downwardly through the material, or after passing upwardly when normally opened valves 156, 256 are electrically closed. The containers 11, 21 are preferably glass cylinders containing, or sintered, to a glass filter bed and hold a measured sample of resin. The apparatus comprises a normal pH recorder which is connected to the electrode cells in turn. It comprises a type-wheel for printing identity symbols on the record so that the progress of the ion removal value of each sample may be followed. An electric motor 100 drives cams 101, 111, 121 controlling the electromagnets of the valves to produce a given timed sequence of treatment of the samples and an electric motor 300 drives selector switches 301, 302, 303, the aforesaid type-wheel and cams closing switches 52, 62 in turn, each a short time after the selector switches have rendered the system responsive to a selected electrode cell. Cams 50, 60 operated by the recorder and responsive to the pH value measured close a switch 51, 61, one at a maximum value and the other at a minimum value so that the appropriate valves are actuated to change the electrolyte when the effluent reaches either pH value. The sequence provided by the arrangement described is : upward flow of water for 1 minute ; downward flow of water 20 minutes ; sodium hydroxide (I per cent) 30 minutes or until pH = 10.2; acid (.003N- two parts by weight H 2 SO 4'  one part HCl) until pH = 4.2, followed by water for 20 minutes. Both samples are simultaneously regenerated by alkali or the apparatus may be modified to effect regeneration individually. More than two samples may be handled by an extended apparatus, indicating lamps show the treatment in progress in each container.

Filed: 1917-10-03
Abstract: 129,041. Wilson, W. G. Oct. 3, 1917. Stroke, varying; valves, arrangement of.-The Specification describes a measuring-pump for introducing liquid into a projectile fuse in which the timing is controlled by the escape, of the liquid. The pump comprises a piston 2 which is movable in a cylinder 1, a reservoir 8, a filler 7, and a stop device for regulating the stroke of the piston. This stop consists of a nut 3, adjustable on a fixed screw 4 through which the piston-rod passes, and having an arm 5 adapted to be clamped in a predetermined position to the inclined graduated edge of the filler 7. A spring- pressed sleeve 26 on the cylinder 1 has a bellmouthed end 30 for fitting over the nose of the fuse, and the cylinder has a valve nozzle 23, for entering the fuse. In use, when the piston is pressed down, against the action of a spring 17, to the position shown in Fig. 10, it first of all closes ports 20 leading from the reservoir to the cylinder, and then forces out the liquid in the cylinder through the valve 21 into the fuse-body. The quantity of liquid discharged is dependent on the stroke of the piston, which' is determined by the position to which the stop 3 is set.
