Title: Electromagnetic Pump
IPC: F04B17/04
Filed: 1980-09-08
Abstract: An electromagnetic pump of the built-in electromagnetic valve type including an electromagnetic plunger actuating electromagnetic coil 4 and an electromagnetic valve operating electromagnetic coil 5 disposed coaxially in adjacent relationship and having magnetic paths of their own separated from each other by a non- magnetic portion, to obtain a desired magnetic flux distribution. The two electromagnetic coils have the same direction of windings to obtain an improved magnetic flux distribution, thereby providing improved pump operation. By passing a half-wave rectified current or a pulse current of a predetermined cycle to the two electromagnetic coils connected in series with each other, a magnetic flux can be produced in each electromagnetic coil and made to flow in the magnetic path exclusive to each electromagnetic coil, so that mutual interference of the magnetic fluxes produced by the two electromagnetic coils can be avoided. <IMAGE>

Title: Improvements in Unsaturated Polyester Resins
IPC: C08F299/04
Filed: 1980-12-18
Abstract: A composition comprises an unsaturated polyester resin and including at least one terminally unsaturated ???-olefine containing from 18-40 carbon atoms inclusive, preferably in an amount of from 0.1 to 1% inclusive by weight. The ???-olefine imparts thixotropy to the polyester composition and, when the composition is made up into a laminate structure, prevents air inhibition of the surface of the laminate and, where styrene is present, reduces emission thereof. The composition can be made up by heating a mixture of the polyester resin and the unsaturated ???-olefine to dissolve the ???-olefine in the resin.
Patent GB-2070751-A (GB)
Title: An apparatus for processing a powdered or particulate product
IPC: B01J8/36
Filed: 1981-02-10
Abstract: An apparatus for processing, e.g. drying, a powdered or particulate product, such as milk powder, operates with a so-called vibrated fluid bed and comprises a bed plate (12) placed within a housing (11). This bed plate is made from thin sheet metal in which a great number of openings (55) of the "lipped" type are punched. The stiffness of the plate is obtained by means of corrugations (52, 53) which extend transversely to the flow direction of the product (P) to be treated in the apparatus. In operation the housing (11) and the bed plate (12) mounted therein are vibrated by means of a vibrator (15), and gas is passed upwardly through the bed plate openings (55) which are formed so that at least the major part of the gas flows will obtain a horizontal flow component directed towards the outlet (26) for the dried product, whereby it is obtained, that despite the transverse corrugations of the bed plate the apparatus is self-emptying, when the supply of a product (P) to the apparatus is stopped. <IMAGE>

Patent GB-2085179-A (GB)
Title: Thermal recording sheet
IPC: B41M5/333
Filed: 1981-09-03
Abstract: A thermal recording sheet has a paper or plastics support coated with a layer which color-forms on heating containing essentially (a) an electron- donating colorless dye as particles of volume average size not exceeding 2.0  mu m and (b) particles of an electron acceptor. The particles are formed by ball milling or sand milling the colorless dye (chromogen), e.g. by using balls of size 1 to 5 mm, in an aqueous solution of a protective colloid, e.g. polyvinyl alcohol. The dispersions are mixed together and with other coating components e.g. pigment and binder. The chromogen can be a triaryl methane, diphenyl methane, xanthene, thiazine or spiro compound. The electron acceptor can be a phenolic or aromatic carboxylic acid derivative, especially a bisphenol. The fine particle size of the chromogen gives rapid color forming with adequate color density with short heat pulses of 2 ms.

Patent GB-2104988-A (GB)
Title: Automatic adjuster for a vehicle brake
Inventor: HENSON ERIC
IPC: F16D65/14
Filed: 1982-08-24
Abstract: An automatic adjuster for a shoe drum brake has a strut composed of a pair of threadedly interengaged parts (11, 20) one of which has a helical gear portion (22) engaged with a similar gear portion (25) on an adjuster member (23). The latter includes a clutch formed by a flange (26) and a normally non-rotatable ring (28), which flange and ring are normally urged into engagement by a spring (29). When wear of the brake shoes occurs, outward movement of the strut causes strut part (21) to be rotated by relative movement of the helical teeth with the adjuster member (23) held stationary by the clutch and the strut length increases. Adjuster operation ceases when the strut load is sufficient to move member (23) against spring (29), thereby rendering the adjuster operation load- insensitive. <IMAGE>

Title: Method and reagents for the use of  beta -D-galactosidase as a tracer in immunocytochemistry
Inventor: CHIEREGATTI GIORGIO
IPC: C12Q1/34
Filed: 1983-01-18
Abstract: beta -D-galactosidase is used as tracer in an immunoenzyme cytochemical method for the identification of antigens in tissues. The enzyme tracer may be linked to the antigen via a specific binder e.g. an antibody specific to the antigen and the antigen can then be revealed by action of the enzyme tracer on a chromogenic substrate which converts to an insoluble coloured product. A reagent kit for use in the method comprises (1) an antibody specific to the antigen, the tracer enzyme which can be in the form of a conjugate and (2) the chromogenic substrate. A universal reagent comprises the chromogenic substrate and a  beta -D-galactosidase conjugated anti-antibody. The use of  beta -D- galactosidase has many advantages over the use of the conventional peroxidases.

Title: Burners
Inventor: RILEY ERIC KEITH
IPC: F23D14/32
Filed: 1984-08-31
Abstract: Oxygen is introduced through oxygen supply line (5) into an annular gallery (6) which it leaves at high velocity through annular channel (7). The outlet of the annular channel (7) is shaped so that, by virtue of the Coanda effect, the oxygen travels towards the downstream end of the burner (1) substantially parallel to the wall of the tubular body (2). Combustion gas from combustion chamber (13) is induced between bars (4), which support the burner body (2), into the tubular body (2) by the flow of oxygen, and mixes with the oxygen and subsequently with natural gas introduced through fuel supply line (8). The mixture burns at the outlet (9) of the fuel supply line (8). The maximum temperature reached by the gas leaving the burner (1) is substantially lower than that which would be obtained by a conventional oxy-fuel flame. The burner may be used in radiant tubes. The oxygen may be replaced by oxygen-enriched air. <IMAGE>

Title: Surface-activated amorphous alloys for electrodes in the electrolysis of solutions
Inventor: HASHIMOTO KOJI
IPC: C22C45/00
Filed: 1984-09-19
Abstract: Amorphous alloys for electrodes in the electrolysis which are surface-activated and consist of 10-30 atomic percent P and/or Si, 20 atomic percent or more Pd and 20-50 atomic percent Ru, Rh, Ir and/or Pt. The alloys sometimes contain further 15 atomic percent or less Ti, Zr, Nb and/or Ta. By surface activating certain amorphous alloy electrodes (generally known from GB 2051158B) their electrocatalytic activity is enhanced. The electrodes may be surface activated by diffusing zinc into the surface and then leaching the zinc from the surface. The electrodes may be used from the electrolysis of dilute sodium chloride solutions to produce sodium chlorate, for the electrolysis of bromides or of organic compounds or as electrodes in batteries or fuel cells.
