Title: Process for the hot mixing of light-coloured wet-precipitated silica fillers
IPC: C08J3/215
Filed: 1961-12-22
Abstract: A process for hot mixing of light-coloured, wet-precipitated silica fillers with natural or synthetic rubber or rubber-like elastomers is characterized by the filler being used in the form of a rubber-filler masterbatch which has been obtained by wet coagulation of natural or synthetic rubber latex in an aqueous suspension of a silica filler produced from a precipitated silica which, after being precipitated, has been subjected to a treatment with an acid in a pH range from 2 to 4, whereafter the suspension is adjusted to a pH value of 4 to 7.5, then admixed with the latex and the rubber coagulated whereafter the coagulated latex/filler master-batch is dried at a temperature of 100 DEG  to 140 DEG  C.

Abstract: 1,210,756. Moderating neutrons. MITSUBISHI DENKI K.K. 1 Oct., 1968, No. 46558/68. Heading G6P. The calorific value of petroleum is measured by observing the thermal neutron flux within the petroleum produced by the moderation of fast neutrons by the petroleum hydrogen atoms. The neutron count rate is a measure of the hydrogen per unit volume and the calorific value corresponds to the carbon-hydrogen ratio. The pipe-line 10; mounted in stand 14, carries the petroleum to be measured. A measuring tube 16, which extends through 10, encloses both the fast neutron source 18 and the thermal neutron detector 20 which are supported from 14 by the rod 22. The vibrations in the pipe 10 are not transmitted to detector 20.

Abstract: 1286652 Air intakes for gas turbine engines ROLLS-ROYCE Ltd 23 Sept 1969 56751/69 Heading F1G A gas turbine engine comprising a bladed compressor has an air intake in the form of a duct the downstream end of which faces a number of blades of the compressor, the number of blades being sufficiently small so that in operation a pressure wave generated across the opening by the passing blades is defined by substantially parallel pressure bands; the duct comprises also an upstream flow portion the height of which perpendicular to the length of the bands is smaller than the corresponding height of the downstream opening to the extent of substantially producing acoustic cut-off in respect of a discrete tone generated by the pressure wave. In the embodiment shown the compressor is of the centrifugal type comprising a rotor 32 having blades 33.

Title: Manufacture of dimers
Inventor: BAIZER MANUEL MANNHEIM
IPC: C25B3/29
Filed: 1962-12-11
Abstract: In the process of forming hydro-dimers according to the parent Specification in which a solution of aliphatic olefinic esters, carboxamides, carboxylic acids or nitriles are treated electrolytically, in the presence of a conducting salt, the electrolysis is effected using a 5-10% concentration by weight of the olefinic compound, the concentration of the conducting salt is 5-30% by weight, and polymerization is minimized by operating in an atmosphere of oxygen, or by adding an inhibitor.  Preferably pH is maintained at or a little above 7, by adding acid e.g. from the anolyte using a diaphragmed cell at lower pH values, polymerization may be prevented by circulating the electrolyte and applying high C.D.e.g.15-40 A.S.Dm. at 5-20 V.  The cathode used may be Hg, Cd, Sn, Zn, Al, Ni, Pb, stainless steel or graphite, which have an H-overvoltage exceeding Cu. Inhibitors of polymerization include quinone, catechol, and amino-naphthol.  The salts, used at high concentration, are preferably quaternary N compounds e.g. tetramethyl ammonium sulphonate.  A table of product results at different pH values is given.

Title: Retractable ball-point pens
IPC: B43K24/08
Filed: 1964-11-19
Abstract: 1,029,358. Retractable ball-point pens. J. RITTER, [trading as J. RITTER KOMM. GES.]. Nov. 19, 1964 [Nov. 26, 1963], No. 47261/64. Heading B6P. A rear push-button actuated ball-point pen has an operating member or turn button 5 connected to the push-button 4, Fig. 1, by torsionally elastic intermediate members 6. In Fig. 1, pressing push-button 4, which is provided with serrations 11 to prevent the push-button from rotating relative to the human operator's finger and therefore the barrel 1, results in the storing of torsional energy in the intermediate members 6. A pin 10, integral with the pushbutton, engages the turn button 5 to displace the cams 7 thereof from the grooves 8 on the inside surface of the barrel, which grooves define the retracted position. Upon leaving the grooves, the turn button is rotated by the stored torsional energy in the members 6 so that on releasing the push-button 4, the cams 7 of the turn button engage the grooves 9 on the inside surface of a barrel, which grooves define the projected position of the refill 2. In Fig. 3 the push-button is prevented from rotating relative to barrel by radial ears 14 on the push-button engaging grooves 15 on the inside surface of the barrel. However, since the push-button is integrally formed with the turn-button via the torsional members 6, and therefore rotates at the end of an actuation because the turn-button has rotated, the push-button is formed in two parts 12 and 13 with a one-way ratchet mechanism between the parts. Furthermore, in Fig. 3, the turn-button is formed with a tubular extension 18 having an axially resiliently deformable portion 18a. The refill 3 co-operates with a pressure member 22 axially slidable in the tubular member, and this pressure member engages with a pressure pin formed integrally with the upper portion 12 of the push-button. The operation is similar to Fig. 1 with the cams 20 of the turn-button 17 engaging in the grooves 8 for the retracted position and in the grooves 9 for the projected position under the force of the resilient means 18a. In the projected position, the pressure member 22 will engage the lower surface of the turn-button 17. As an alternative, Fig. 4 (not shown), the grooves 8 and 9 may be formed on the turn-button and the cams formed on the inside surface of the barrel. In a modification of the construction shown in Fig. 1, a stop pin of rectangular crosssection enters a recess in the turn-button and prevents the overstraining of the intermediate members 6. In an alternative construction, Fig. 4a (not shown), the stop pin is attached to the intermediate members and engages both the push-button and the turn-button when the push-button is pressed.

Abstract: 1476109 Position control CINCINNATI MILACRON Inc 18 Nov 1975 [25 Nov 1974] 47482/75 Heading G3N In a position control apparatus e.g. for a machine tool an input instruction is modified by a stored compensation signal, to reduce positioning errors, before feeding to an actuator control circuit 14. The compensation signal is derived over repeated cycles of the input instruction by comparing the intended final position of the controlled element, represented by the input signal at 18, with its actual final position, measured by a measuring circuit 26. The sign and/or magnitude of the difference between the intended and actual final positions is used to modify at 32 the existing stored compensation signal whereupon the new compensation signal is entered in store 22 in its place. In order that the response to long term errors e.g. due to tool wear or temperature changes is maximized and the response to random errors, which may change sign from one cycle to the next, is minimized, the correction to be applied to the existing compensation signal is preferably a fixed increment which is added or subtracted according to the sign of the position error. Alternatively it may be a percentage of the error.
