Abstract: 1360594 Load handling pallets BAMBERGERS PALLETS & CASES Ltd 28 May 1971 [4 June 1970 8 Dec 1970] 21285/70 and 58253/70 Heading B8H A pallet comprises an envelope formed of upper and lower sheets of flexible plastics material between which a rigid support member 11 may be inserted for lifting the loaded pallet. The member 11, which is mounted on lift forks, is hollow and wedge-shaped and its leading edge 12 is formed with apertures 14 through which compressed air from a compressor issues to facilitate the entry of the member between the sheets. As shown, Fig. 3, the envelope is of flexible material having sealed side edges, a closed end 4 and a mouth 6. At the mouth, the material is folded inwardly at 7 to form pockets 8 which fill with air and provide a seal around the support member 11 as it is inserted. When the member 11 is fully inserted, the air supply is turned off so that the flat upper surface of the member 11 takes the weight of the load. In a modification, the envelope is formed with a mouth at each end to provide two-way entry, Figs. 7, 8 (not shown). A four-way entry pallet may be formed by superimposing two two-way entry envelopes at right angles to each other. In a further modification, Figs. 11-13 (not shown), the envelope is formed from a length of tubular plastics material, one end being closed by heat sealing and, at the other end, the lower portion extends beyond the opening and the upper portion is folded back and heat sealed to support a transverse wooden rod.

Title: Adhesive compositions
IPC: C09J161/24
Filed: 1943-12-24
Abstract: An adhesive comprises a water-soluble ureaformaldehyde condensation product in admixture with fish glue, which may be present in the proportion of 10-25 per cent by weight of resin solids.  As low a proportion as 2 per cent may be used, and higher than 25 per cent if the water-resistance of the bond is not important.  Hardening agents such as acids or acid salts may be added shortly before use, or the surfaces of the adhesive coatings may be coated with a thin film of a solution of a hardening agent. One or both of the surfaces to be bonded may be treated with a priming composition.  Examples describe: (1) the bonding of aluminium sheet to felt with the adhesive containing phosphoric acid, first priming the metal with a composition containing linseed oil-modified glyceryl phthalate; if desired, the felt may be pre-coated with an emulsion of synthetic resin or a cellulose derivative; (2) the bonding of leather to cotton fabric with the adhesive containing ammonium chloride, with a pre-coating as under (1) if desired; a similar technique is stated to be applicable to the bonding of leather to leather.  The adhesives are also stated to be bonding agents for wood, synthetic resins such as phenol-formaldehyde mouldings, woven fabrics, paper and cardboard products, plywood and laminated paper products, and boot and shoe parts.  Specification 582,662 is referred to.

Title: Memory devices providing non-destructive reading
IPC: G11C13/04
Filed: 1972-05-10
Abstract: 1348606 Digital data storage COMMISSARIAT A L'ENERGIE ATOMIQUE 10 May 1972 [14 May 1971] 21809/72 Heading G4C A semi-conductor substrate 10<SP>1</SP> (Fig. 4), having a forbidden energy band E g  and two intermediate levels separated by an energy E i , the lower level being at energy E p  from the top of the valence band and the high level being at an energy E c  from the bottom of the conduction band, has a matrix of diodes formed on it, writing being effected by populating the lower of the two intermediate levels and non-destructive read out being effected optically by raising the electrons at the lower intermediate level to the higher level. As described for a substrate having a trapping level having normal and excited states, writing is effected either by selectively forward biasing the diodes or by using a light source of energy hv p  > E p  (e.g. an argon laser) to bring, for a selected diode, electrons in the valence band to the trapping level. Reading is then effected by applying a light source of energy hv 1 , E i  <hv 1 < E e +E 1 , to a selected diode. If information is stored in the diode the electrons at the trapping level are raised to the exciting level absorbing the light so that there is no output from a detector (comprising a mosaic of scintillator crystals associated with photomultipliers). If however no information is stored the light passes through the substrate to the detector. Alternatively read out may be effected by luminescence or by detecting the rotation of the plane of polarization of a light beam which is different in dependence on whether the light falls on charged or vacant traps. Erasure is effected by illuminating all the diodes with a light beam of energy hv f  where E i +E e  < hv f  < E p  so that electrons in the trapping level pass to the conduction band but the trapping level is not populated with electrons from the valence band.

Title: Improvements in or relating to four stroke internal combustion engines
IPC: F01L5/06
Filed: 1920-07-21
Abstract: 171,740. Meunier, A. F. July 21, 1920. Valves, regulating. - In an engine in which main inlet ports b and exhaust ports care controlled by a single reciprocating sleeve valve d, the admission taking place late in the suction stroke, the resistance during the suction stroke is reduced bv admitting air or combustible mixture during the suction stroke through a port a<1> which may be controlled by an additional port in the sleeve and by a rotary valve j. In order to use the engine as a brake, the timing of the sleeve valve and of the valve j may be altered by axial adjustment of a sleeve on the countershaft. This sleeve has an external thread which passes through the boss of the gear wheel driving the valve j, so that axial adjustment of the sleeve gives a partial rotation to the wheel and alters the timing. The same control lever also operates plug cocks o, p, which shut off the carburettor q from the admission ports a<1>. b, and connect these ports to the atmosphere. When set for braking, the piston draws in air through the exhaust ports c during one down-stroke, and compresses it on the up-stroke; the air then escapes through the port a<1> and the rotary valve j, and a vacuum is formed in the cylinder on the next down-stroke; air is admitted through the inlet port b at the end of this stroke, compressed on the next up-stroke, and discharged through the exhaust port c at the end of the stroke.

Title: A method of and apparatus for controlling and also proportioning flows of combustible fluid
IPC: F02D1/08
Filed: 1922-08-11
Abstract: 204,826. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Aug. 11, 1922. Fluids, regulating volume of flow of; electrically-actuated valves.-Apparatus for controlling and proportioning the flow of combustible fluids to provide a mixture having a constant calorific value, and controlled by a calorimeter in which a sample of the mixture is burnt has the calorimeter arranged to act through a wheatstone bridge and electric ratchetting mechanism. The Figure shows the apparatus arranged to control the flow of one of two combustible fluids of different calorific values. The supply of both fluids may be controlled by controlling the speed of the apparatus inducing the flow or by other means or the supply of one constituent alone may be regulated by means such as a power actuated valve 8. The control apparatus comprises inter alia a calorimeter of the kind described in Specification 153,817, [Class 86, Mixing &c.], in which combustible fluid from the conduit 5, combustion air, and cooling air are supplied to a burner by wet displacement pumps 9, 10, 11, driven by a common motor 12. Resistance thermometers 14, 15 arranged in the stream of the cooling air are connected through an adjustable rheostat 17 to the opposite arms of a Wheatstone bridge 16 so that differences in the rise of temperature produce a deflection of the galvanometer needle 18. This needle is arranged to work between two series of contacts 19<1>, 19, the lower contacts being intermittently raised by an electromagnet 20 controlled by a rotating switch 21 driven by the motor 12 so as to clamp the needle between certain of the contacts. This completes a circuit through the rotating switch 21 so that one or other of the magnets 22, 23 of the ratcheting device 24 is energized so as to move the contact of the rheostat 17 in the sense to restore the balance. This movement actuates a recorder 26 and also moves a contact 30 on a second Wheatstone bridge, so causing defection of a. galvanometer needle 18<a>. This needle also moves between a double series of contacts to control the ratcheting mechanism 24<a> adapted to actuate the valve 8 in a similar manner to the needle 18 and ratcheting mechanism 24. This movement of the valve is arranged to be in the sense to restore the balance of the Wheatstone bridges and maintain the calorific value of the gas at the value set by the adjustable arms 29 of the second Wheatstone bridge and indicated on the scale 33. In a modification a single Wheatstone 'bridge is used to control other mechanism 24a. Specification 136,200, [Class 86, Mixing &c.] also is referred to.

Abstract: 519,520. Purifying gases. GRIFFIN, J. D. July 25, 1938, Nos. 22087 and 23211. [Class 55 (ii)] [Also in Groups I and VI] In order to remove excess sludge collecting 'in a trickling filter charged with aerobic bacteria used for purifying liquids or gases, the filter is filled with liquid up to the surface of the filtering-medium and air or other gas is forced in below the clogged part of the medium. A closed casing 1 containing filter media 2 on a permeable support 3 is connected to a pipe 4 through which air or other oxygen-containing gas can be admitted, and to a pipe 6 through which gas to be purified can be admitted. A blower 8 is provided for forcing the gases through the filter. Liquid containing impurities or nutrient liquid is admitted through a pipe 11 opening on to a rotary spreader 13 which with the blower 8 is rotated by an electric motor 9. The gases are discharged through a pipe 14 and the liquid through a trap 17 into a pipe 18. Increase of resistance to flow may be determined by measuring periodically the flow of gases through the filter by means of a manometer 19 bridging an orifice 20, or the gaseous pressure difference between the top and a lower part of the filter by means of a manometer 21. To clear the filter the speed of the motor may be increased. If this is ineffective the filter is filled with liquid from the pipe 11 or by liquid forced in by a pump 26 and compressed air is supplied through a pipe 29 or a perforated pipe 30 connected to a pipe 29a. The sludge may be discharged through a valve 27. Specification 446,066, [Group I], is referred to.
