Abstract: 1,258,103. Trunks. R. J. TORRES. 2 April, 1969 [2 April, 1968], No. 17415/69. Heading A3V. A pair of trunks, which may be used as underpants or for sportswear, is made from three pieces of material namely, a main panel 1, a ventrally disposed gusset 8 and a waistband 14. The main panel 1 is sector shaped with the point cut off to form a rectilinear base 6 and has lateral edges 4a, 4b bent round and stitched to edges 11a, 11b of the gusset 8 which is generally in the form of an isosceles triangle with two corners cut away forming curved edges (12a), (12b), Fig. 3 (not shown) which, together with cut away edges 5a, 5b of of the sector, form the leg apertures of the trunks. The gusset is formed with a slot whose edges (10a), (10b) are joined to form a pleat, the edges (13a, 13b) then forming a straight base edge that is stitched to the base 6 of the main panel 1, and the angle at its point is such that the edges 11a, 11b form smooth extensions of opposed ends 2b, 2a of the curved edge 2 of the main panel 1. The waistband 14, preferably made of elastic fabric, is then stitched at the edge 2 and its extended ends 14a, 14b are stitched along the line of stitching securing the gusset and main panel. Elastic bands 15a, 15b are then applied to the edges of the leg apertures and stitched to the extended ends of the waistband 14. The pieces may alternatively be assembled in a different order.

Abstract: 1,264,255. Two-stage hydrogenation. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 26 June, 1970 [2 July, 1969], No. 31237/70. Heading C5E. Unsaturated hydrocarbons are hydrogenated in two stages, 20-99% of the hydrocarbons being converted in liquid phase in the first stage in the presence of a catalyst in homogeneous phase; and the conversion being completed in a second stage in the presence of a fixed bed of catalyst in heterogeneous phase. The first stage catalyst may be obtained by reaction of a transition metal compound with a compound containing Al-H bonds. Preferred catalysts are the reaction products of LiAlH(OtBu) 3  or AlH(OtBu) 2  with cobalt naphthenate. The second stage catalyst may be a Group VIII metal e.g. Pt, Pd or Ni supported on a carrier. The product of the first stage may be passed though a bed of absorbent e.g. Al 2 O 3  or SiO 2  before the second stage. The feedstock may be monodi- or tri-olefins, acyclic or cyclic. Examples describe the hydrogenation of cyclododecatriene to cyclododecane, cyclopentadiene to cyclopentane, and cyclooctadiene to cyclooctane.

Abstract: 1,265,335. Active filters. WESTERN ELECTRIC CO. Inc. 27 Feb., 1969 [29 Feb., 1968], No. 10449/69. Heading H3U. The number of multiplier circuits required in a digital filter is reduced by repetitively using a modified nth order filter on each digital input, with the multiplier constants of the filter being changed with each use. In one embodiment, Fig. 1, each digital input is temporarily stored in a register 11, and while stored, is applied to a filter 12 whose outputs are accumulated in accumulator 13. Sets of multiplier constants for the multipliers in filter 12 are supplied sequentially by circuit 14 which, together with circuits 11, 13, is timed by circuit 15. In operation, register 11 is timed so that each digital input is applied to filter 12 until all the sets of multiplier constants have been read out of memory 14, and accumulator 13 is timed so that each of its outputs comprises the accumulation of a particular number of outputs from filter 12. In a modified arrangement, Fig. 4 (not shown), the circuits 11, 13 are replaced by switches which in one position recirculate the filter output back to its input. The filter 12, Fig. 3, comprises delays 57 ... 64, multipliers k 1 , k 2  feeding back to an input adder 50, and multipliers l 0 , l 1 , l 2  feeding an output adder 51.

Abstract: 1311875 Vehicle driving means HERBERT MORRIS Ltd 4 Sept 1970 [6 June 1969] 28794/69 Heading B7H [Also in Division H2] Motor vehicle drive means comprises a rotary induction motor having a rotor disc B coupled to the propeller shaft of the vehicle and two pairs of coils C energized through forward and reverse switch means from an alternator A2 driven at constant or variable speed by a gas turbine or I.C. engine A. When the alternator is driven by an I.C. engine the alternator output is controlled by the engine speed according to the position of an accelerator pedal. In Fig. 3 the alternator supplies the coils C through an isolating switch SW1 interlocked with the bonnet of the vehicle and a forward contactor 12 or a reversing contactor 13 controlled by switches SW5, SW6 respectively. An inertia switch SW4 opens the forward contactor 12 in the event of a collision or other violent stoppage of the vehicle. In a modification, Fig. 4, the coils C are supplied through a static thyristor controller in which thyristors D9, D11, D15, D17, D21, D23 are turned on for forward drive and thyristors D12, D14, D15, D17, D18, D20 are turned on for reverse drive.

Abstract: 1322701 Temperature control of exothermic reactions N WADDLETON (ANDERSON LUEDEKA FITCH EVEN & TABIN) 29 June 1970 [1 April 1969] 16930/69 Heading B1X Exothermic reactions are controlled by means of indirect cooling fed from a constant level surge drum, wherein any coolant losses due to evaporation are replenished with fresh coolant. In the particular application of converting fatty nitriles to amines reactants are fed into a reactor 1 via an inlet 6, and stirrer 29 is started. The mixture is first heated by passing steam through coil 31 and any excessive condensate collecting in surge drum 32 is removed via lines 36, 50. Pressure control 66 opens valve 34 to atmosphere during this time. Pump 22 circulates the reactants via line 7, heater 2 and header 21 and when the reactants are at the required temperature the valve 34 is closed and the steam heating stopped by closing valve 55. Hydrogen is then introduced into the reactor via sparger 15 and NH 3  through line 16. Heat emitted is controlled by passing a coolant, e.g. H 2 O through the surge drum 32, line 36 and the coil 31. Any coolant vaporising is vented via pressure relief line 33 whereupon the level in drum 32 drops. The level controller 35 then causes valve 40 to open to admit make up coolant. Upon completion of the reaction valves 34, 51 are opened and valve 52 is closed so that the mixture may be further cooled.

When the material reaches a desired level in the container 10 an indicator 55 actuates a control panel 60 through which the direction of motor 30 is reversed and thus the direction of operation of the blower 40 is also reversed such that air is drawn in through conduit 41 and forced by the blower 40 through conduits 44, 46 consecutively into the container 10 to convey the material out through the discharge conduit 48 which is connected by a fitting 49 to a line (not shown) leading to a utilization area. In the event of a pressure build-up in the discharge line a valve 47-V is opened automatically to permit air to pass directly into the line to remove the blockage. When the container 10 has been emptied the control panel is actuated to cause reversal of the motor and blower to reinstigate the filling of the container.
