Title: Improvements in or relating to bearing structure for viscous crankshaft dampers
IPC: F16F15/173
Filed: 1953-05-27
Abstract: 740,641. Torsional-vibration dampers. HOUDAILLE-HERSHEY CORPORATION. May 27, 1953 [Sept. 27, 1952], No. 14749/53. Class 108 (3). A-vibration damper comprises a closed housing providing a chamber 31 for an inertia member 32, a shear film of viscous damping fluid between opposed working surfaces of the member 32 and chamber 31 the fluid in the presence of direct rubbing together of the material of the housing and member 32 tending to bind them together, the member 32 having on a limited portion of the working surface areas thereof most liable to make frictional contact with the housing, a buffer member which is normally operatively spaced out of contact with an opposing working surface area portion of the housing. As shown, the buffer member comprises bearing means in the form of bronze rings 35, 37 which bear on respective housing surfaces which are separated by a fluid reservoir 40. The rings 35, 37 project axially of the ring member 32 by about 0.004 to 0.008 ins. (which is less than the thickness of the shear film). A thrust plate 43 secured by screws 45 co-operates with the axial surface of the ring 37, and is accommodated by a rabbet groove 47 in the ring member 32. The reservoir 40 is connected with the working surfaces by axial grooves 41 peripherally spaced in the inner surface of the rings 35, 37. The grooves 41 open into radially-disposed grooves in the outer axial faces of at least one of the rings 35, 37. As shown, the latter grooves are formed in the ring 37 and are continued by tapering grooves 42 in the corresponding axial surface of the ring member 32. There may alternatively be a single bearing ring extending the whole axial thickness of the ring member 32 (Fig. 4, not shown). The thrust plate 43 may be dispensed with and the corresponding outer axial face of the bearing ring then terminates adjacent the cover-plate 30. The bearing ring may be an interference or press fit in the member 32 and may be held from relative rotation by pegs. In a modified construction the ring member 32 operates in fully-floating spaced-relation in the casing and carries a bearing ring on its outer periphery (Fig. 7, not shown). This ring may be equal in length to the axial thickness of the ring member 32, or it may project slightly beyond each axial face of the member 32. The casing and flywheel surfaces may be plated with cadmium. The bearing rings may be flash-plated with cadmium, or may be zinc plated. Specifications 636,881 and 638,755 are referred to.

Abstract: 420,100. Control systems for welding- apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and KNIGHT, H. DE B., 108, Eastlands Road, Rugby. May 26, 1933, No. 15276. [Class 38 (iv)] In an arrangement for " shot " welding in which the welding electrodes pass a heavy current for a predetermined short period of time an impedance S in series with the primary of the welding transformer W is short circuited by one or more grid controlled vapour discharge tubes TI whose grid circuits include a timing circuit in which a condenser C2 is charged through a resistance R3 and determines the period of the " shot ". The timing circuit may be supplied with A.C., or D.C. or through a rectifier T2 from the A.C. supply. A switch K2 controls the operation and in its position b short circuits the condenser C2, whilst in position a the welding operation is started and lasts until the condenser C2 is charged sufficiently to block the discharge tube T1. The period of the " shot " may be varied by (a) altering the position of the cathode tap A on the potentiometer R1, R2 from which the timing circuit is supplied, (b) adjusting the resistance R3, (c) varying the capacity C2 by an additional condenser or a series parallel arrangement of condensers. A variable resistance R4 in the primary circuit of the welding transformer may be used to control the welding current and a resistance R5 may be connected across the welding electrodes to minimize the effect of surges on the operation of the discharge tube T1.

Patent GB-235589-A (GB)
Title: Improvements in resinous condensation products and method of preparation
IPC: C08G63/127
Filed: 1925-06-12
Abstract: In order to obtain a resin capable of being hardened by a comparatively short heating, the hardening of the complex ester resins, produced by interaction of a polyhydric alcohol such as glycerine and a polybasic acid such as phthalic acid or its anhydride, is interrupted when the resin is just short of the intermediate stage of condensation, the interruption being obtained by heating the fusible resin dispersed in a solvent of high boiling point so as to effect a partial "curing."  Suitable solvents are diethyl phthalate and benzyl benzoate.  The solution may be heated to 210-290 DEG  C., any evaporated solvent being recovered by condensation, and after a sufficient time the resin is precipitated, for example by pouring the solution in diethyl phthalate into benzene, and dried.  The resulting resin is susceptible of quick hardening and is non-corrosive. Specification 3271/13 is referred to.

Patent GB-354851-A (GB)
IPC: C09K23/00
Filed: 1930-05-20
Abstract: Sulphuric esters of aliphatic alcohols containing at least 9 carbon atoms in the molecule are used in the acid felting of wool, e.g. with sulphuric, acetic, lactic, or formic acid.  The felting process is accelerated, and the material becomes clearer and softer than when the sulphuric esters are not added to the felting liquid.  In an example, octadecyl sulphuric acid ester is added to a sulphuric acid felting liquid.  The sulphuric esters of lauryl and stearyl alcohols are also mentioned.  The esters are prepared by treatment of the alcohols with sulphonating agents, e.g. oleum or chlorsulphonic acid, if desired in the presence of inorganic or organic acid anhydrides or chlorides, or by addition of sulphuric acid to the corresponding olefinic hydrocarbons.
