Title: Improvements relating to milk coolers
IPC: F28D3/00
Filed: 1921-03-01
Abstract: 180,442. Turpin, E. B. March 1, 1021. Cooling milk.-In a milk-cooler of the kind employing spaced corrugated sheets, the sheets are provided with eyes and a number of rods engage the eyes so as to connect the sheets together and to form a sinuous path for the cooling- water. In the construction shown, the interior hollows of the corrugated sheet 1 are provided with eyes 2 formed by strips of metal soldered thereto and the interior apexes of the other sheet 3 are formed with juxtaposed eyes 4. In position the eyes 2, 4 register, and rods 5, the length of each of which is about three-quarters of the width of the sheets, are inserted from alternate sides to form a continuous sinuous path. In a modified construction some or all of the hollows of each sheet and some or all of the apexes of each sheet may be provided with eyes and rods. To facilitate cleaning the hollows of the sheets where they join the uprights 6 of the frame are rounded; this may be effected by cutting out a V-shaped piece at each end and bending and soldering the edges 8, 9, or instead of cutting the sheets the ends may be pinched and beaten. To ensure the water chamber remaining full the outlet 10 is arranged above the part 11 of the water chamber.

Title: Improved means for locking containers on vehicles
IPC: B60P1/64
Filed: 1941-05-26
Abstract: 549,611. Road vehicles. NATIONAL FITCH CORPORATION. May 26, 1941. No. 6753. Convention date, Aug. 2, 1940.

Title: Improvements in or relating to knitting machines
IPC: D04B9/20
Filed: 1941-05-27
Abstract: 549,612. Knitting-machines. BOOTON, Ltd., W. E., BOOTON, W. E., STRETTON, J. W. K., and BOOTON,. J. H. May 27, 1941, No. 6763. Addition to 537,965. [Class 74 (ii)] The picker mechanism claimed in the parent Specification and comprising a driving member swung or moved sideways by a control butt and a picking member movable thereby to pick a needle jack so that a butt thereon acts in turn as a control butt, has the picking member 38b of sufficient width to engage and pick two or more jacks. A cam 56x is provided for returning the unwanted jacks to the position they occupied prior to being picked. As described, the mechanism is employed for fashioning at the leading edge of a blank knitted by rotary knitting, and the trailing jacks of a group L of fashioning needles are selected and raised by the picking mechanism. The additional jacks lifted by the mechanism and returned by the cam 56x are the leading jacks of the adjacent group T of needles. The needles and jacks of the group T have already been raised to operative position, and the butts of this group engaged by the member 38b belong to a series of butts 39 arranged lower on the jacks than the butts 38 upon the jacks of the group T engaged by the member 38b. The jacks of the group T are therefore raised to greater height so that butts 40 thereon engage the cam 56x and are lowered to the same height as the newly added jack of group L. The face of the driving member 38a which makes contact with the first butt of the trailing group T, i.e. the control butt, is of such depth that the control butt maintains contact with it while another butt on the same jack is being raised from its line through a distance greater than the height or thickness of this other butt, so that a dividing cam may be used to complete the upward movement of the jack.

Title: Improvements in or relating to electrical artificial tranmission lines
Inventor: ROSENBROCK HOWARD HARRY
IPC: H01P5/02
Filed: 1948-03-04
Abstract: 653,004. Artificial lines. GENERAL ELECTRIC CO., Ltd. March 4, 1948, No. 6788. [Class 40 (viii)] An artificial transmission line comprises a coil of metal strip with its major surfaces in planes parallel to the coil axis and a second similar coil or a metal sheet separated by a dielectric sheet between at least part of the opposing major surfaces of the conductors. A coil 1 of metal strip is wound on a rectangular former 2 and separated from a metal sheet 3 by a sheet of dielectric material 5. The assembly is mounted on an insulating base 6. A balanced line comprises two such lines with the metal sheets lying in parallel planes and conductively connected together. In this case there is little electromagnetic coupling between the coils, but a balanced line with substantial coupling between the coils comprises two coils of metal strip wound on rectangular formers with opposing sides separated by a dielectric sheet. Such a coil has a greater electrical length for out-of-phase currents in the coils than for inphase currents, and a half-wave line can be used as an unbalanced-to-balanced transformer by making the electrical length for in-phase currents equal to a quarter-wavelength. By varying the cross-section of the coil, as described in Specification 653,005, or by varying the width of the metal strip, a line with impedance varying with electrical length is obtained.

Title: Process for the preparation of glass fibre mats
IPC: D04H1/587
Filed: 1975-02-18
Abstract: 1459163 Glass-fibre resin mats KAO SOAP CO Ltd 18 Feb 1975 [28 Feb 1974] 6795/75 Heading D1R A styrene soluble chopped or continuous strand glass fibre mat is uniformly bonded with 2.5 to 10% by weight based on the wt. of the fibres, of particles of a binder resin comprising 25 to 100% by wt. of polystyrene or a copolymer of styrene and at least one comonomer, said copolymer containing at least 50 mole % of styrene units, said polystyrene or copolymer having a m.p. of 100 to 150C and a number average molecular wt. of 2500 to 7000, any balance being an unsaturated polyester resin having a m.p. of 80 to 130C. Preferably a styrene homopolymer is used but α-methyl styrene, acryonitrile, methyl methacrylate, ethyl acrylate, vinyl toluene and butadiene are suitable comonomers. The unsaturated polyester resin is formed from a diacid and a polyol, e.g. ethylene glycol, diethylene glycol, propylene glycol, neopentyl glycol, butane diol, trimethylpentane diol, hydrogenated bisphenol A or wherein R is C 2 H 4  or C 3 H 6 , A is a 2 alkylidene group having 3 or 4 carbon atoms and n and m are integers 1 or 2 with n + m no more than 3. Glycerol may be included when diol I is employed. The diacid comprises 100 to 20 mole % of an α, #-unsaturated dicarboxylic acid or anhydride (maleic acid, maleic anhydride, fumaric acid or itaconic acid) and 0 to 80 mole % of succinic acid, adipic acid, azelaic acid, sebacic acid, phthalic acid or anhydride, tetrahydrophthalic acid or anhydride, isophthalic acid, terephthalic acid, methylisophthalic acid or methylterephthalic acid. The glass strands comprise 200 to 400 9 to 13 micron diameter filaments and may be laid to form a continuous strand mat or out into 1 to 2 inch staple fibres. The binder is applied to the mat as a powder of 40 to 200 mesh (J.I.S.) or as an aqueous dispersion of 200 mesh or finer particles. Up to 2% of a higher fatty acid metal salt or silica may be added to the powder as lubricant. The impregnated mat is transferred to a 180 to 240C oven for 2 to 3 minutes then compressed by a cooling roll. The mat is immersed in a vinyl monomer solution of an unsaturated polyester or vinyl ester resin and the resin cured at low pressure and room temperature in the presence of a catalyst. The vinyl monomer is normally styrene: it may alternatively be vinyltoluene, α-methylstyrene, chlorostyrene, methylmethacrylate or mixtures thereof. A 4 X 5 inch mat sample subject to a 100 g tension breaks after 5 to 20 seconds immersion in styrene, thereby demonstrating the rapid dissolution of the binder.

Abstract: 718,058. Pulse amplifying circuits. GENERAL ELECTRIC GO., Ltd., and PEDDLE, B. A. R. March 17, 1953 [March, 1952], No. 6855/52. Class 40 (6) A pulse amplifying circuit comprises a coldcathode discharge tube which fires when a triggering pulse is applied to the trigger electrode, a capacitor connected to the cathode or anode being charged or discharged when the tube is fired so that the tube is extinguished after a piedetermined time interval and an output pulse is produced across an anode or cathode resistor. Fig. 1 shows a pulse repeater in which cold-cathode tube 1 fires when a positive triggering pulse is applied at terminal 10 and capacitor 5 Which was previously charged from the H.T.+ supply at 3 is discharged through the tube 1 until the fall in anode voltage causes the tube to be extinguished. Capacitor 5 recharges from the H.T.+ supplyand a positive-going output pulse is produced across cathode resistor 4. In a modification shown in Fig. 2 capacitor14 charges during the period when tube 1 is firing and subsequently discharges through resistor 13, a negative-going output pulse being produced across anode resistor 12. The trigger input circuit is arranged to present a high input impedance.
