Title: Improvements in and relating to metal cutting and grinding machines
IPC: B23B29/06
Filed: 1946-02-01
Abstract: 607,405. Combined turning and boring &c. machines. ANDERSON, J. Feb. 1, 1946, No. 3319. [Class 83 (iii)] [Also in Group XXIII] In a metal facing, boring, turning or grinding machine, a tool slide having tools on at least two sides is mounted on a slide bracket rotatably adjustable on a support member supported at both ends and is fed towards the work by a hydraulic cylinder, the tool slide having a slot through which the support member passes; to adjust the tools initially relative to the work, the support member can be rotated on eccentric mountings on its two supports, swung about a pillar forming one of the supports and adjusted along and at right angles to the pillar axis. The tool slide h, Figs. 7 and 8, is recessed round three sides to receive tools j, j<SP>1</SP>, j<SP>2</SP>, and the fourth side is connected to the ram g<SP>1</SP> of a hydraulic feed cylinder g carried by a slide bracket f having guides for the slide. The slide bracket is rotatable on a support member d so that the feed movement towards the workpiece t held in a chuck t<SP>1</SP> may be at any angle, and the bracket is locked in the adjusted position by a sleeve r and nut q. A slot i in the tool slide accommodates the sleeve rand permits feed of the slide relative to the support member. The support member is carried by two brackets b, c, Fig. 5, the bracket b being fixed by a screw x to a pillar u rotatably mounted in the machine table, and the bracket c being adjustable circumferentially round the pillar u in a slot o<SP>1</SP>, Fig. 2, in which it may be locked by a nut o<SP>2</SP>. The support member is attached to the bracket b by an eccentric spindle e and to the bracket c by a collar l slidable on a rod m on the bracket ; the collar has a locking screw l<SP>1</SP> and a pin k<SP>1</SP>, coaxial with the spindle e, on which an eccentric k on the support member is rotatable and slidable. The support member has tommy holes e<SP>3</SP> for rotating it and the adjustment is locked by a nut e<SP>1</SP>. The rod m is supported between pins n eccentric to the axis of the rod and has a knurled head p to enable it to be rotated to provide a fine circumferential adjustment; a hand wheel p<SP>1</SP> locks this adjustment. Adjustment along and at right angles to the axis of the pillar u, after release of the screw x and, in the first case, the collar locking screw l<SP>1</SP>, is provided, respectively, by a hand wheel b<SP>6</SP> engaging a screwed spindle b<SP>3</SP> on the bracket b<SP>2</SP> engaging the bracket b ; tommy holes w are provided on the pillar. One or more such tool rigs may be provided on the machine and motor-driven drills or grinding-wheels may be substituted for the cutting tools j, j<SP>1</SP>, j<SP>2</SP>.

Abstract: 1372964 Recording and playback ING C OLIVETTI & C SpA 26 Jan 1972 [28 Jan 1971] 3730/72 Heading G5R In a recording/playback system, a cartridge 69 containing a closed loop of magnetic tape 68 is loaded on to a unit 10 in order to engage the tape with a head 27 and a capstan 17, and a pressure roller 76 is rotatably supported in the cartridge by two biased lever arms 83, 84 independently pivotable about a shaft 86 whereby to press the tape against the capstan with uniform pressure. In the arrangement shown, the arms are biased by a U-shaped fork 104 which is in contact with an adjustable lever 107 (Fig. 3) and loading spring 113, and the roller 76 is formed with raised outer portions 77 underlying a resilient layer 78 which is thick in the centre but thin at the edges in order that the capstan and pressure roller can directly contact each other at the edges, and thereby subject the tape to less wear. Among other features, the drive to the capstan 17 is applied through an electrically controlled clutch 18, and the cartridge is located in the unit 10 by means of two arms 66, 67, two hooks 22, 52 which co-operate with two cartridge slots 137, 138, and four notches 36, 37, 44, 46 in four arms 33, 34, 42, 43 which cooperate with the exposed end portions of each of two cartridge shafts 132, 86.

Title: Improvements in or relating to pit-props
IPC: E21D15/28
Filed: 1953-02-12
Abstract: 745,654. Pit props. BUSCHMANN, A. Feb. 12, 1953 [March 4, 1952], No. 3936/53. Class 20(2). In a telescopic pit prop having vertical drag wedge 3 and horizontal pressure wedge 4 the wedge 3 has projections 5 and an intermediate plate 9 has projections 13 which engage in horizontal slots 6 in the snap lock and move therein when the plate is moved by either wedge. The drag wedge 3 is maintained in its topmost position by a spring 14. The prop is set by wedges inserted in slots 19 and engaged alternately with the bottom of the part 2 and an opening 21 in the part 2.

Patent GB-1463773-A (GB)
Title: Periodically actuated pneumatic ratemeter
IPC: G01P3/26
Filed: 1975-01-29
Abstract: 1463773 Fluidic rate-meters DRESSER INDUSTRIES INC 29 Jan 1975 [13 Feb 1974] 3952/75 Heading F1P An apparatus for monitoring the rate of pressure impulses in a fluid-pressure line comprises tanks 14, 15, Fig. 1, for storing a gas, a restriction 16 for allowing leakage from the tanks at a predetermined rate and gating means 13 responsive to impulses from the line for alternately connecting the tanks to the restriction 16 and to a pressure gauge 18. As described, the apparatus is used to indicate the rate of pump strokes, and a pump rod operates a valve 2 on every stroke of the pump. This causes pulses from an air source 19 to be amplified by valves 3, 5 and counted by a pneumatic counter 6. The output of the valve 5 also changes the state of a bi-stable binary counter 9 so that every time a signal is received the output is switched from one of output ports 31, 32 to the other. If a range charge switch 11 is connected to counter 9, alternate actuations of valve 2 will operate a valve 12, whilst if the valve 11 is connected to a counter 10 every fourth actuation of valve 2 will operate the valve 12. The latter amplifies the signal and transmits it to the gating valve 13. When the latter is not receiving a signal the tank 14 is connected, as shown in Fig. 1, to a supply of compressed air 24 and the tank 15 is connected to the pressure gauge 18. When the valve 13 receives a signal the two tanks are connected together and to the bleed restriction 16. Thus, when the valve 13 is not receiving a signal the pressure remaining in the tank 15 is proportional to the time between pump strokes. The system is calibrated either by adjusting the regulator 17 or making the restrictor 16 variable. The embodiment shown in Fig. 3, is similar except that two gating valves 62, 71, are provided and also two pairs of tanks 63, 64 and 72, 73. The valves are arranged so that whilst one pair of tanks is connected to the bleed restrictor 80 one tank of the other pair is being charged and the other is connected to the pressure gauge 78. Thus, a pressure reading, and therefore a pumping rate, can be read at each stroke of the pump instead of at alternate strokes as in the case of the apparatus shown in Fig. 1

Title: Process for the production of beryllium compounds from beryllium-bearing minerals
IPC: C01F3/00
Filed: 1934-02-06
Abstract: Beryllium-bearing minerals such as beryl or pegmatite are mixed with sufficient alkali metal bifluoride or other alkali metal compound containing the HF group to form with the beryllium an alkali metal beryllium fluoride and the mixture heated say to 550--800 DEG  C., whereafter the pulverulent or sintered decomposition product is leached, for instance with hot water, to bring into solution the soluble double fluoride formed.  In place of alkali metal bifluoride a mixture of substances adapted to form such bifluoride, for instance calcium fluoride and sodium bisulphate, may be used.  The double fluoride solution may be treated with ammonium silicofluoride to form ammonium beryllium fluoride solution and alkali silicofluoride which is precipitated and removed.  By concentration the ammonium beryllium fluoride is recovered, and this may be directly heated to form beryllium oxyfluoride, or be first mixed with beryllium oxide, hydroxide, or carbonate and then gently heated to give the oxyfluoride. Alternatively the double fluoride solution may be treated with caustic soda to precipitate beryllium hydroxide, and the latter be suspended in water and treated with ammonia and carbon dioxide, whereby on boiling the resulting solution beryllium basic carbonate is obtained.  Examples of procedure are given. Literature references include mention of French Specification 476,465.

The widths of the targets 29, 30, 31 may increase successively. In another modification, the envelope is semicircular and the targets are semi-annular, the envelope lying in the field of a horseshoe magnet the lines of force of which follow approximately the targets.
