Title: Method and equipment for supplying machines for producing a continuous tobacco rod, for example cigarette-making machines
IPC: A24C5/39
Filed: 1961-12-08
Abstract: 1,007,308. Pneumatic conveyers; transferring apparatus; shoots. K. KÍRBER. Dec. 8, 1961 [Jan. 4, 1961], No. 44029/61. Headings B8A and B8S. In a method of pneumatically conveying tobacco through selectable suction pipe lines 137, Fig. 2, leading to separate delivery boxes of tobacco utilizing machines, predetermined quantities of tobacco are intermittently fed to one cell 81, Fig. 1, of a multiple cell drum 70 which, after filling, is rotated until the filled cell 81 is aligned with the selected suction line 137 for pneumatic conveyance of the material in one batch. The method reduces to a minimum the drying of the tobacco by the conveying air. The tobacco, which may be of more than one grade, is stored in pairs of multiple containers 11-14 having belt feeders 17, spiked drums 18 and rollers 24, 25 operable selectively for predetermined time intervals to deliver required quantities of tobacco to two pairs of longitudinal belt conveyers 50, 51 and two pairs of transverse belt conveyers 60, 61 delivering the tobacco to a hopper 92 arranged above the cell wheel 70. After delivery the tobacco is pressed into the cell 81 by a pivoted pusher 95 which, on retraction, actuates trip switch 80 controlling the drive of the cell wheel 70. The amount of rotation of the cell wheel is preselected from an automatic control system, Fig. 4 (not shown) set according to the tobacco demand and interlinked with trip switches 112 surrounding the drum shaft 75 and engaged successively by a cam 121. The cam 121 is rotatable on the drum shaft 75 and is automatically coupled by a clutch during rotation of the drum 70 and moves against a torsion spring which automatically returns the cam 121 to its initial position against an end stop 141 after each operation. Specification 1,007,309 is referred to.

Abstract: 1,014,867. Welding by pressure. K. V. SLEE. Feb. 19, 1964 [Nov. 21, 1962], No. 44065/62. Heading B3R.  A welding head 1 carrying an electrode 3 is guided for straight line movement in the frame 2 of a welding machine by rectilinear roller bearings each having a series of rollers 9 movable along V-grooves 14 in races in the frame 2 and head 1, some of the rollers of each series rolling upon different surfaces of the V grooves. The races 10, 13 on the frame 2 are laterally adjustable. The head 1 is actuatable manually hydraulically or pneumatically. The actuating mechanism may be a foot pedal operated lever device connected by a compression spring to the welding head 1. When at the required welding pressure the spring is compressed a predetermined amount, a microswitch operates to cause a pulse of welding current to be supplied to the electrode 3.

Title: Anti-skid braking system
IPC: G01S13/92
Filed: 1971-09-22
Abstract: 1346678 Anti-skid systems BENDIX CORP 22 Sept 1971 [30 Sept 1970] 44140/71 Heading F2F A vehicle anti-skid system is operated by an assessment of percentage slip derived from measurements of vehicle speed and wheel rotational speed, both measurements being made by Doppler-effect radar. There is one vehicle speed sensor 68 directed towards the road at an angle 0, and it receives back slightly modified signals from the road surface, which it mixes with the transmitted signal to produce a difference frequency. This is converted to a linear voltage analogue. The wheel speeds may be detected by conventional tacho-generators but, as shown, are likewise detected by radar transmitters 70, 72, 74, 76 respectively. The signals derived from these sensors passes through Signal Processor 78 which controls a brakepressure modulator 50 acting, as shown, on all wheels. As shown in Fig. 3, the vehicle and wheel-speed sensors 68, 70 feed into the processor 78 in which the received signals are filtered and combined in a divider 88, the output from which passes to an adder 90. The signal from this is combined in another 92 adder with a programmed wheel slip signal derived from the vehicle speed. The output from this is an error signal, i.e. the difference between actual and programmed slip, and this goes to the modulator 50b to eliminate this error. Total slip is in any case, limited by limiter 100. In an alternative circuit (Fig. 4, not shown) rate-of-charge of slip is fed to the logic unit.

Catalysts having an unusual degree of selectivity for hydrogenation and other reactions are prepared by reacting an ion-exchange resin in particulate form with a solution of a metal compound to form a resin-metal complex in which the metal moiety is chemically bonded to the resin, e.g. by ionic or coordinate bonds, and reacting the complex with a reducing agent to reduce the metal to a state of lower valency. The metal may be Cu, Ag, Au, Zn, Cd, Hg, Sc, Y, La, Ac, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Co, Ni, Ru, Rh, Pd, Pt, Os and Ir and is preferably reduced to zero-valent state. After the reduction of the metal the catalyst may be treated with a regenerating agent to regenerate the functional groups of the catalyst. These catalyst can be used in reactions involving hydrogenation, carbonylation, or formylation of unsaturated compounds.

Abstract: 1,149,148. Polymerizing lactones. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 11 Oct., 1967, No. 46405/67. Heading C3R. Polyesters are made by the catalytic polymerization of a #-lactone having a tertiary or quarternary α-carbon atom in the presence of solid particles of the said #-lactone, which solid particles are kept in vigorous motion in an inert gaseous atmosphere. Polymerization is effected in the substantial absence of liquid solvents or diluents by a batch or continuous process. Vigorous motion of the polymerized lactone is achieved by stirring or by keeping the particles in a fluidized state. Suitable inert gases are air, carbon dioxide, nitrogen and saturated hydrocarbons. The monomeric lactone may be supplied to the polymerization vessel in liquid or gaseous state, and if polymerization is effected in a fluidized bed may be added to the stream of fluidizing gas. The initial polymerization reaction may be carried out in the presence of inert particulate materials (e.g. glass beads or ceramic material) which may be gradually removed from the reaction vessel. The particles removed from the polymerization reactor may be heated to polymerize any unreacted monomer, e.g. in an extruder. Various additives may be added to the extruder. Examples describe the polymerization of pivalactone in the presence of triphenyl phosphine (polymerization catalyst) and p-chlorobenzenediazonium hexafluorophosphate (monomer stabilizer).
