Patent GB-1229892-A (GB)
IPC: C08J7/046
Filed: 1968-04-09
Abstract: 1,229,892. Coating. MBT CORP. 9 April, 1968 [5 May, 1967], No. 16933/68. Heading B2E. A method of treating plastics or elastomeric materials to improve the surface characteristics thereof, comprises contacting the surface of a plastics or elastomeric material in a moisturecontaining atmosphere with a hydrolyzable, essentially water-free organic silicic ester having a functional organic group which is bonded to silicon through an oxygen atom and no direct carbon-silicon bond, or a silane having an organic group bonded directly to silicon through a carbon-silicon bond and three hydrolyzable groups bonded to silicon, to form a bonding film having an interface with said surface, and contacting the thus-formed film in a moisture-containing atmosphere with a second hydrolyzable silicon compound such as a silicon halide having four halogen groups bonded to silicon or a silicic ester having a functional group which is bonded to silicon through an oxygen atom and having no direct carbon-silicon bond, in the presence of a suitable catalyst when a silicic ester is used, to effect formation on said bonding film of a layer of silica or silica gel which is stabilised at said film and which is characterised by being hydrophilic, oleophobic when wet, and harder and more electrically conductive or antistatic than the surface treated. The formation of the bonding film and the silica or silica gel deposit may either be effected in the vapour phase or by applying the compounds in the form of dilute organic solvent solutions. In one embodiment, the treatment is carried out with a solution containing both a hydrophobic bonding film-forming compound and a silica- or silicagel-forming compound, said compounds having different evaporation and hydrolysation rates. The film and silica or silica gel deposit are preferably formed in an atmosphere having a relative humidity above 10%. Typical examples of silicic esters employed to form the bonding film are tetramethylorthosilicate, tetra-beta-chloroethylorthiosilicate, tetra (2-methoxy-ethoxy) silane, triethoxysilane, vinyloxytriethoxysilane, &c, whilst suitable silanes used for forming this bonding film are vinyltrichlorosilane, vinyltrimethoxysilane, vinylsilanol, triallyloxyvinylsilane. Typical compounds used for forming the silica or silica gel deposit are tetrachlorbsilane, trichlorosilane or tetramethylorthosilicate. The bonding film may be formed from a reaction mixture comprising a silane containing an amino group, e.g. gamma-aminopropyltriethoxy silane and a silane containing an epoxy group, e.g. beta-(3, 4 epoxycyclohexyl)-ethyltrimethoxy silane. The method may be employed to treat a dampening roller employed in offset printing, ophthalmic lenses arid dentures.

Abstract: 1,230,920. Roller conveyers; selective retrieval. FLUGHAFEN FRANKFURT AM MAIN A.G. 16 May, 1969 [23 Aug., 1968], No. 25035/69. Addition to 1,230,916. Headings B8A and B8E. A stand-by system, particularly for luggage pallets of a conveyer at an airport, comprises stand-by tracks 113 which preferably slope downwards towards releasable barriers 115. Pallets moving along an entry track 114 are diverted, e.g. according to a flight number or time, by points 125 into the stand-by tracks 113. When the pallets are required, the barriers 115 are opened and the pallets, due to belt driven wheels 2<SP>11</SP>, pass to an exit track 116. The drive for each stand-by track is via a magnetic clutch 123, but all the tracks 113, 114, 116 include idler wheels 91. For transferring pallets from one track 113 to one or more other stand-by tracks, the pallets are moved to an exit track 116, then to a return line 117 whence they are distributed by points 125 to other tracks 113 as required. If a required track 113 has been filled, pallets may be transferred to a bypass track 118 and then back, via tracks 116, 117, to the entry track 114, ready for feeding to another track 113. A number of track arrangements as above may be superimposed, the tracks at various levels being interconnected by tracks 119, 120 (also Figs. lb, 1c, not shown). The drive for the exit track is preferably more rapid than that for the stand-by tracks.

A valve adapted to be inserted as a unit in a flow conduit of an I.C. engine cooling system, comprises a substantially cylindrical member 10 having a transverse wall 11 formed with a seat 17, and spaced from the wall a spring abutment 14 with a flow passage 15, a valve head 18 movable towards and away from the spring abutment against the action of a compression spring 19, and a temperature responsive actuator 21 disposed coaxially of the member 10 and attached to the wall by means of a stirrup 22 on the side opposite the abutment 14 and having its actuator member 23 attached to the head 18. The head 18 is formed by a cup-shaped member shaped so that initial movement produces only a relatively small opening. The wall 11 is attached to the member 10 by a turned over portion which produces a rim so that the valve can be fitted in a rubber hose 25 and secured by clips 26, 27.

A shoe support, e.g. for use in a shoe bottom roughing machine of the type described in Specification No. 1,137,254, has a template T which can be rotated through 180 degrees so that it can be set for operation on a left or right shoe and a safety device which prevents the machine from operating unless the shoe S corresponds to the setting of the template T. The shaft 302<SP>1</SP> which carries the template T has two cams 610, 612 one of which opens a first valve when set for a left shoe and the other of which opens a second valve when set for a right shoe. The heel clamp 197<SP>1</SP> is pivoted at 602 such that a left shoe will cause it to depress a valve plunger 606 (full line, Fig. 2) and a right shoe causes it to depress a valve plunger 608 (shown dotted). The two sets of valves are interconnected and are included in the control circuit of the machine so that the machine will not operate unless both the template sensing valves and shoe sensing valves are both set for operation on a left or right shoe. If the wrong shoe is placed on the work support the machine will not operate until the template T is turned through 180 degrees by the actuation of a manually operated valve (not shown).

Abstract: 1289847 Photo-electric position finding GRAVIMETKICS Inc 3 Oct 1969 48679/69 Heading H4D [Also in Divisions G1 and H2] A seismograph comprises an electromagnetically levitated body 8 which is held in a stable horizontal and vertical positions by the spatial distribution of the magnetic field of an electromagnet. Three photo-detectors 26, 28, 20 are spaced apart at the vertices of an equilateral triangle so that detectors 26, 28 measure horizontal movement and detector 20 vertical movement. A light source 14 is energized by oscillator 10 through modulator 12 to produce a pulsating light of narrow bandwidth which is collimated by lens 16 into a beam which passes around the periphery of disc 8 to illuminate the detectors. The apparatus is contained within a transparent vacuum tight housing 6. In operation a disturbance will result in relative movement of body 8 and cause the output of one or all the detectors 26, 28, 20 to charge. The output of detectors 26, 28, since they will normally charge in opposite directions, are added at resistor 40 and applied to amplifier 42 whereas the output of detector 20 is applied direct to amplifier 42. The output of amplifier 42 is integrated at capacitor 43 and applied to winding 44 of electromagnet 48. The energization level of winding 44 is monitored by winding 46 whose output can be recorded or supplied to a computer as a measure of the disturbing force.
