Title: Improvements in light machine guns
IPC: F41A3/36
Filed: 1930-11-26
Abstract: 367,862. Machine guns. PELO, C., Tavastehus, Hameensaari, Finland. Nov. 26, 1930, No. 35629. [Class 92 (ii).] A toggle-lever breech action for recoiloperated machine guns has a toothed segment 7 on the lever 4 co-operating with a fixed rack 8 the arrangement being such that, during the first phase of the rearward movement and the last phase of the forward movement of the breech-block 3, when the toggle-lever 4, 6 is in line with the barrel, the engaging teeth of the segment and rack form a lock for the breech-block. The lever 4 is pivoted to the barrel extension 2 at 5 and the link 6 is hinged to the breech-block. On recoil of the barrel and after unlocking of the breech-block, the teeth 7 gear with the rack 8 and rotate the lever 4 to break the toggle mechanism and open the breech.

Title: Temperature control system
IPC: G05D23/24
Filed: 1976-05-27
Abstract: 1537256 Temperature control WARD BLENKINSOP & CO Ltd 27 May 1976 [29 Aug 1975] 35839/75 Heading G3R An on-off valve 11 for supplying heating fluid to a chemical process plant is operated in response to the output of a thermistor 1. The thermistor output is amplified at 2 and passed to a flip-flop 3 which also receives a clock-pulse input from a unit 4. A relay 6 is operated by change-of state of the flip-flop, i.e. whenever the sensed temperature attains a given value, but can only be operated at the instant of a clock pulse. This prevents spurious triggering and, depending on the clock pulse frequency, may also minimize overshoot and/or undershoot.

Abstract: 904,087. Conduit fittings. HUSLER, N. W. Jan. 23, 1961 [Oct. 23, 1959], No. 35913/59. Class 36. An elbow fitting for trunking of rectangular box formation has front and rear cover-plates 10, 11 and wall sections 12, 13, these components being held in their assembled position by screws passing through suitably drilled holes and engaging clip nuts 14 fitted on the various components, the nuts for the rear coverplate 11 being so placed that its screws may be engaged with or disengaged from their nuts from within the assembled fitting after removal of the front cover-plate. The cover-plates 10, 11 are recessed along their sides 101, 111 to receive the side flanges of the wall sections and are further recessed at 141 to accept the nuts clipped to the components, thus allowing flush fitting of the covers. Strips 16 welded to the components limit travel of the attached trunking into the elbow. In an alternative form of the elbow, Fig. 5 (not shown), the wall section 12 is replaced by two parts meeting at the corner of the elbow, these parts being separately removable. Nuts non-rotatably held in cages and nuts otherwise fixed to the components may be used as alternatives to clip nuts, and the method of assembly of the elbow may be applied to junction fittings of arcuate, T, or cruciform formation.

Certain organic nitrogen compounds which are formed during the distillation of coal, such as those contained in commercial anthracene and in the residues obtained in naphthalene production, or the product obtained by mixing coal tar oil or anthracene oil with concentrated sulphuric acid at 300‹ C., may be used as inhibitors. In examples, a substance containing sulphonamide, and thiocarbonilide are employed. The Specification as open to inspection under Sect. 91, includes the use, with the acid, of any substance which delays the solu-. tion of the iron. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,007,061. Seaming non-metallic sheet material; laminates. FACTORIES DIRECTION Ltd. Sept. 14, 1964 [Sept. 12, 1963], No. 36033/63. Headings B5K and B5N. A sheet is made from small strips 1 of material by joining the strips 1 together end-to-end to form a continuous strip which is wound spirally on a drum to form a tubular shell from which a relatively large sheet is obtained by cutting in a direction lengthwise of the shell. The strips 1, e.g. of veneer, may be of various lengths but have a standard width and thickness, and they are scarf jointed end-to-end or stuck to a supporting paper strip to produce the continuous strip 2, Fig. 1 (not shown). The strip 2 is trimmed to uniform width and wound into a coil. The strip is laid spirally on the drum 4 to form a butt-joint between neighbouring coils. The joining together of neighbouring coils may be effected by sticking the strip to a paper carrier which may be applied to the drum surface either before or after the strip is wound on to the drum. The cut along the drum runs along a curved line 5 intersecting the joints between neighbouring coils at right angles to form a rectangular sheet. The projecting end 6 is trimmed off.

Title: Method of and apparatus for the automatic preparation of emulsions by phase inversion
IPC: A23D7/02
Filed: 1961-10-09
Abstract: 966,336. Emulsions, making. ETABLISSEMENTS BRUNEL FRERES. Oct. 9, 1961 [Oct. 11, 1960], No. 36174/61. Headings B1C and B1V. A method of preparing emulsions by an automatic procedure comprising the steps of introducing an emulsifier and a first liquid separately and successively into a zone in a closed circuit in predetermined quantities, causing said emulsifier and said liquid to be mixed in said closed circuit by means of a high delivery centrifugal pump, which causes them to circulate in said circuit, optionally adding colouring agents or other additives in predetermined quantity to said mixture in said zone and thereafter introducing another liquid into said zone in the closed circuit to dilute the mixture to the required extent. As shown in Fig. 1, a cylindrical tank C is fitted with tube T leading to the intake of a centrifugal pump P e  which when controlled by a regulator R 1 , Fig. 2, circulates emulsifier and oil which are provided successively in predetermined quantities through pumps P 1  and P 2 . Stoppage of pump P 2  initiates the addition of any other additive, e.g. colouring agents, through pump P x  which in turn initiates the addition of water through electromagnetic valve V for dilution to the required extent or phase inversion. Closure of valve V stops pump P e  and the prepared emulsion is delivered through pipe S and pump P v  to storage. Pump P v  stops when the delivery pressure measured on pressure device M has dropped to zero or when the regulator R 2  operates to retain a portion of the emulsion in tank C. One or more pumps P x  may be provided and the cycle may be restarted by pressure regulator R 1 , Fig. 2, provided on the storage tank. The apparatus may be operated manually and can be used as a phase inverter. The examples describe the preparation of both oil-in-water and water-in-oil emulsions. Fig. 2 diagramatically represents the control sequence of the feed pumps, valve, and mixing pump.

Two pairs of walls are separated by a partition (122) [Fig. 2 (not shown)] under which the fabric passes, the passages in the walls of the second pair being inclined upwardly.

Title: Well cementing devices
IPC: E21B33/14
Filed: 1946-12-23
Abstract: 619,740. Well and borehole apparatus. DEHN, S. G. (Baker Oil Tools, Inc.). Dec. 23, 1946, No. 37759. [Class 85] A cementing tool is secured between casing sections 11, 12 and comprises a ported tubular member 10 having secured therein a tubular body 13, the centre portion of which is of reduced diameter so that an annular chamber 18 is formed between the body and the member. Mounted in this chamber is a rubber skirt 20 forming a non- return valve to the ports 19 in the body. During operations prior to the cementing, fluid flow through these ports is prevented by a sleeve 23 held in position by a shear screw 24, the fluid passing down the tool through a non-return valve 30. When it is desired to commence the cementing operation, a ball 26 is passed down the casing string on to a seat 25 on the sleeve 23 so closing the passage through the tool. The fluid pressure in the casing is increased parting the shear screw and forcing the sleeve downwards to uncover the ports 24 so that cement grout can be forced down the casing string out into the space between the casing and the borehole through the ports 24 past the non-return valve and through the ports 16. In an alternative construction, the tubular body moves axially of the tubular member, it being held against an upper shoulder of the tubular member by a shear screw so that flanges formed on the lower end of the tubular body seal off the ports in the tubular member from the annular valve chamber. On the increase of fluid pressure in the casing string after the ball is seated on the tubular body, the shear screw is parted and the tubular body moves downwards so that the flanges uncover the ports in the tubular member so permitting outward flow of the cement grout.
