Abstract: 778,065. Drilling-machine details. BUSWELL & SWEENEY, Ltd. Nov. 5, 1954 [Nov. 5, 1953], No. 30552/53. Class 83 (3). [Also in Group XIX] A measuring appliance for jig-boring &c. machines has a carriage 1 with spaced, separate, gauge-blocks 2, the interblock spaces being pitched apart by distances equal to a unit of measurement, any one space being engageable by a datum-plate 3 and the carriage being displaceable through fractions of a unit by a micrometer 6. The carriage 1 moves longitudinally on bearings 4b in the recess 4a of the machine-saddle 4. A spring 13 urges the micrometer-head 7 against the operating-member 8 of a dial-gauge 10 in a housing 11 secured to the saddle 4 by a bracket 12. A sleeve 15 in the machine-table 16 carries a stop 18, located below the plane of the blockfaces, in grooves 19 to abut the datum-plate 3. With a workpiece on the table, the micrometer is zeroized and the member 8 adjusted by rotation of shaft 20 so that the gauge-reading is zero. The stop 18 is adjusted in the sleeve 15 till it abuts the datum-plate. The table 16 may then be moved through any multiple of unit distances by engaging the datum-plate in the appropriate space and abutting the stop 18 against it, and through a fraction of a unit by operating the micrometer before bringing the stop into abutment with the plate, ensuring each time that the gauge-reading is zero. The device may be arranged vertically, the datum-plate being mounted on a cursor carrying a stop to contact the work. The gaugeblocks and stop are removable. . Reference has been directed by the Comptroller to Specification 718,548, [Group XIX].

Patent GB-341443-A (GB)
Title: Process for manufacturing dispersions
IPC: B01F3/12
Filed: 1929-10-09
Abstract: Aqueous dispersions of asphalt, tar, pitch and the like, prepared with the aid of finely divided solids such as bentonite or colloidal oxides hydroxides or silicates, are treated with an electrolyte, in quantity sufficient normally to cause flocculation of the dispersion or with two or more electrolytes added in admixture or in succession, flocculation being prevented by adding the electrolytes gradually and with continued beating of the dispersion.  The beating may be effected in the apparatus described in Specification 334,100, [Class 81 (i), Disinfecting &c.], and may be continued after the electrolytes have been added.  Electrolytes may also be added to the dispersing agent. Protective colloids such as gums, starch dextrine, tapioca flour or tannin may be added before, during, or after the treatment. Suitable electrolytes are sulphuric, hydrochloric, phosphoric, chromic, oxalic, or benzoic acid; acid salts such as potassium dichromate, aluminium sulphate, or acid sodium or calcium phosphate; and magnesium or calcium oxide or hydroxide.  In examples: (1) Mexican asphalt is dispersed with an aqueous suspension of equal parts of bentonite and New Jersey pottery clay, to which 10 per cent of potassium dichromate has been added.  The dispersion, containing 20 to 50 times as much asphalt as dispersing agent is then beaten during the gradual addition of 0,3 per cent phosphoric, 0,4 per cent chromic, or 0,1 per cent hydrochloric acid, or 1 per cent potassium dichromate, relative to the weight of the dispersion.  The addition is preferably made in small increments, each being added only when the beating action has dissipated the flocculation induced by the previous one.  The dispersion gives a rust inhibiting coating to metal surfaces.  (2) Coal tar is dispersed in water with a bentonite suspension made alkaline with sodium carbonate, or ammonium or trisodium phosphate.  An acid salt, an acid, or a mixture of a basic and an acid substance, in similar quantities as are used in (1), is then added while beating.

Abstract: 882,478. Liquid meters; fluid-pressure servomotor control systems. CANADIAN INDUSTRIES Ltd. Sept. 7, 1960 [Sept. 10, 1959], No. 30804/60. Classes 69 (1) and 135. Apparatus for measuring the flow of liquid in which large fluctuations in temperature and viscosity occur comprises a flow divider to the downstream arms of which are connected a pair of constrictions, a constant volume pump controlling the flow in one stream and means for determining the pressure drop across each constriction. In the apparatus shown for measuring the flow of fluid taken from a conduit 1 the fluid is passed through a flow divider 3 to the limbs of which are connected two preferably identical constrictions 4, 5. These may be capillary tubes, nozzles, orifice plates or Venturi tubes. The first stream passes through a constant volume pump 6 and back to the conduit 1. If the pump is placed before the constriction 4, the streams are passed through coils in a temperature equalizing bath before passing through the constrictions. The pressure drops across the constrictions are measured either by manometers when the flow in the second stream is calculated manually or by pneumatic or electrical pressure differential cells 7, 8 from which signals are sent to a divider 13 and the flow rate is shown and recorded by recorder 14. A pneumatic signal from divider 13 may be transmitted through tube 15 to a pneumatically-controlled diaphragm valve 16 to control the flow of fluid to its point of use.

Title: Devices for sowing, growing and transplanting seedlings of sugar beet or other root-crop vegetables
Inventor: NIIMOTO YATSUO
IPC: A01G9/10
Filed: 1959-09-10
Abstract: In order to facilitate the transplanting of root crops, the seedlings are grown in open ended tubes containing soil and made of material which will break when eventually subjected to pressure from the growing root.  Initially, the tubes are placed vertically in a hot-bed and are each filled with a suitable soil into which one seed is sown.  When the seedlings have grown sufficiently, they are transplanted by removing the tubes from the hot-bed and burying them in the planting ground.  Alternatively the tubes may be placed initially in a box provided with a removable, waterproof lining into which is poured a fertilizer solution, in which case the lining of the box may be used eventually as a bag to transport the tubes and seedlings to the planting ground.

Abstract: 212,856. Vickers, Ltd., and Elia, G. E. Jan. 2, 1923. Press-button switches; cases.-A switch for use on cables attached to submarine mines for firing the mine when actuated by contact with a passing vessel is enclosed within a flexible sheath m<7>.

Title: Improvements in and relating to electric circuit breakers with arc extinguishing means
IPC: H01H33/76
Filed: 1936-11-17
Abstract: 484,011. Fluid - blast switches. STRAUSS, (nÚe RUPPEL), F. Nov. 17, 1936, No. 31429. Convention date, Nov. 25, 1935. [Class 38 (v)] In a circuit-breaker with arc - extinguishing fluidblast produced by the pressure due to the heat of the arc in a blow-out chamber which is closed with the exception of the opening through which the movable switch - member is drawn out, devices under the influence of the pressure in the blow-out chamber are provided, which act, along at least a portion of the switching-off movement in opposition to the accelerating forces exerted by the pressure in the blowout chamber on the movable switch-member. In one construction, Fig. 2, the arc formed on separating the movable contact 2 from the fixed contact 1 is drawn through a tube 3 of gas-yielding material. An insulating extension 4 of the contact 2 carries a piston 5 movable in a cylinder 6. During the first part of the switching-off movement, the space 9 below the piston is connected with the space 8 subject to the pressure of the arc gases by means of grooves 7 in the wall of the cylinder 6, but during the latter part of the movement the spaces are shut off from one another by the piston, and the pressure of the arc gases in the space 8 exerts a retarding effect. In a modification, Fig. 3 (not shown), the contacts are separated in a chamber filled with water, oil or other liquid, and a piston carried by an extension of the movable contact rod moves in a cylindrical extension of the chamber. In another construction, Fig. 4 (not shown), the movable contact rod is tubular, and carries the piston at its lower end. The Specification as open to inspection under Sect. 91 describes a further modification, Fig. 5 (Cancelled), in which the piston 5 is fixed and the cylinder 6 forms an extension of the hollow movable contact rod 2. This subject-matter does not appear in the Specification as accepted.
