Title: Liquid-phase condensation reactions
IPC: B01D3/14
Filed: 1982-03-11
Abstract: An apparatus suitable for carrying out liquid-phase condensation reactions at atmospheric pressure, consists of a single plate column (6) having three zones. The actual reaction takes place in the central zone, distillation of the reaction product takes place in the upper zone, and separation and discharge of the water of condensation takes place in the lower zone, to provide products in a practically pure condition. A solution of methanol and boric acid is fed to the central zone. The solution descends from plate to plate, reacting to give water and trimethylborate. The latter is stripped by rising methanol vapours into the upper enrichment section for the purpose of increasing the concentration of trimethylborate thereat. The liquid phase descends from the central zone into the lower water/methanol rectification zone for the evaporation of the methanol vapours. <IMAGE>

Title: Linear bipolar transistor circuits
Inventor: MALLINSON ANDREW MARTIN
IPC: H03F1/52
Filed: 1982-12-01
Abstract: A linear bipolar transistor circuit has at least one bipolar transistor (Q1) capable of having voltages greater than the sustaining voltage applied across it, and means to vary automatically the operating point of the bipolar transistor when the voltage applied across the transistor is greater than the sustaining voltage, so that the transistor operates satisfactorily in the manner of a linear amplifier irrespective of the voltage applied across it, usually the means being arranged to cause the ratio of the emitter and base currents, or voltage, to alter in the appropriate way. The means may comprise a feedback connection (D3, D4, Q4, Q2), whereby, when the transistor is an NPN transistor, at least a portion of, any base current flowing out of the transistor is substracted from the instantaneous current flowing in the emitter circuit, when a voltage greater than the sustaining voltage is applied across the transistor.   <IMAGE>

Title: Paper sheet dispenser
Inventor: MARSHALL GREGORY VICTOR
IPC: B65D83/08
Filed: 1983-03-29
Abstract: A paper dispenser (10) has a container body (12) containing a stack of paper (28) and a lid (14) closing the container. A slider (16) is slidable along a slot (20) in the lid to move a member (24) away from and towards a dispensing end (22) of the dispenser. One end of the member (24) is pivoted to the slider while its other end rests on the topmost sheet (26) of paper. To extract the topmost sheet of paper from the stack a user slides the slider (16) away from and then towards the dispensing end of the container. This causes the member (24) first to slide over the sheet and then to push the topmost sheet towards the dispensing end and partially out of the container. The user then draws the sheet from the dispenser by its projecting edge. <IMAGE>

Title: Vibrator unit and apparatus for reclaiming particulate material including such a unit
Inventor: MERRION PETER DEREK
IPC: B07B1/28
Filed: 1983-10-07
Abstract: Material for reclaiming is loaded into a tub 12 resiliently mounted on a base. A motor 17 rotates an out-of- balance weight assembly 15 journalled on the tub 12, so that the latter follows the resultant gyratory movement of the assembly 15. The material is thus vibrated, enabling foreign bodies to be dislodged therefrom and removed. As shown, the material to be reclaimed is foundry sand, lumps of which are broken down by the vibration to pass through coarse and fine sieves 22, 23. Bottom 24 of the tub acts as a conveyer, moving the sand under an adjustable wall 26 into a chamber 27 where airjets 31 agitate it, light particles being carried off at 33. The sand passes through a further sieve 35 to a bin 37. The out-of- balance weight assembly 15 includes sector-shaped weights each with a split clamping portion by which it is clamped to a drive shaft, (Figs 3,4, not shown). <IMAGE>
Patent GB-2147825-A (GB)
Title: Wallcoverings
Inventor: WARREN CHRISTOPHER BERNARD
IPC: D21H11/02
Filed: 1983-10-14
Abstract: A vinyl wallcovering having a base paper ply and a P.V.C. ply is characterised in that whilst the paper ply is conventionally about 85 g/m<2> the P.V.C. ply is significantly lower (e.g. 35 g/m<2>) than the conventional 85 g/m<2>. The loss of reliable strippability and opacity which could follow from the reduction in weight of the P.V.C. ply is made good by arranging that the paper ply has at least two sub-plies one of which is splittable from the other. The sub-ply which does not carry the P.V.C. is typically a low cost mechanical, de-inked or waste furnish with a little woodfree furnish added for extra strength and is of poor colour and brightness. The sub-ply which carries the P.V.C. is a chemically refined woodfree furnish having good colour and brightness. Loss of bulk feel, and some increase in opacity can be made good by causing a degree of foaming of the P.V.C. ply.
