Abstract: 150,213. Phillips, J. E. W. Dec. 10, 1919. Side-car attachments.-Relates to means for attaching side-cars to motor or other cycles, of the kind in which the connecting means, after the side-car has been detached, are capable of being folded up or collapsed against the side-car or cycle to reduce the overall width to a minimum, and consists in arranging at least one set of such connexions, preferably that at the rear end of the cycle, so that no relative sideway tilting between the cycle and the side-car is possible. The end of a hinged bar a, Fig. 2, engages with a lug g on the chassis cross-member b, whilst the terminal eye f, Fig. 5, simultaneously comes into alinement with corresponding pierced lugs h, i, Fig. 7, on the hinged bars a, c respectively. This joint, which holds the bar c rigid and prevents any sideway tilt, is secured by a pin j, retained in position by a cross-pin q engaging a circular slot r in the lug i. To withdraw the pin j, it is rotated against a spring s, until the cross-pin q comes into line with a longitudinal slot t. The front connexions n, o, n may be of similar construction, or may be of any simpler form capable of affording vertical support to the side-car; they need not be collapsible.

Abstract: 690,183. Animal byres. DICKIE & SONS, Ltd., W., and DICKIE, T. June 15, 1951 [June 16, 1950], No. 15053/50. Class 20(i) [Also in Group XXXIV] In byre cleaning equipment of the kind comprising a conveyer 1 in a muck channel 4 having an extension 4a, in which the conveyer is drawn through the channels 4, 4a by a cable 2 which is wound on a winch drum 5, and in which the conveyer is retracted by a cable 3 which is wound on a winch drum 7, the drums 5, 7 are driven by a main clutch 11 and through manually controlled clutches, one being 27, which can be selectively operated e.g. by a lever 29, to drive either of the two drums. In operation a motor 10 drives a pulley 9, and on closing the clutch 11 by means of a lever 25, the drive is transmitted by a shaft 16, and gears 12, 12a to a shaft 13 freely carrying the drum 7, and by further gears 14, 14a to a shaft 15 freely carrying the drum 5. The lever 29 is moved to engage the clutch for the drums 5, which is inside the drum, the clutch 27 being disengaged. Hence drum 5 winds up the cable 2 until a lug 45 on the end of the belt 1 engages a bent part 44a on an arm 44 to pull a cable 42 and pivot a spring-loaded arm 36 carrying a point 35 which serves to hold the lever 25 in one of its two operative positions. On the pawl 35 being moved, the lever 25, which is spring-loaded, moves automatically to its inoperative position and the clutch 11 is disengaged. To retract the belt 1, the lever 25 is moved as before and the lever 29 moved to close the clutch 27 and hence transmit drive to the drum 7, upon which is wound the cable 3. As before a collar on the cable 3 eventually engages a forked arm 39 which pivots at 40 to pull a cable 37 and pivot the arm 36 to release the lever 25 and open the clutch 11. Two conveyers are shown in Fig. 2, and the drums 5, 7 have friction brakes (see Group XXXIV) to control them when unwinding. Specification 525,294 is referred to.

Abstract: 610,818. " Q " measure ment; phase-difference and power-factor measurement. BENDIX AVIATION CORPORATION. June 14, 1945, No. 15177. Convention date, May 3, 1944. [Class 37] The Q of a circuit, e.g. a resonant line, is ascertained by measuring the phase-shift that it produces in the envelope of a wave having a carrier frequency equal to the natural frequency of the circuit and a modulation frequency which is a known fraction of the carrier frequency. As shown, a Hartley oscillator 30 having two tuning ranges and a low-frequency oscillator 108 tuned by a selected one of a number of adjustable delay networks 110, 112, 114, 116, 118 feed a heptode mixer 68 coupled to an anode bend detector 210 by the impedance of the circuit, the Q of which is being measured. The output of this detector feeds the moving coil 240 of a phase meter, the fixed coils of which are fed from the output and from a mid-point on the delay network of the lowfrequency oscillation. In each' tuning range of the carrier oscillator, any one of four of the five delay networks may be selected. The tuning controls of the networks are, however, ganged to the tuning condenser of the carrier oscillator so that the modulation frequency is always a selected fraction of the carrier frequency. The Q value is obtained directly by reading one of two scales on the meter or by multiplying one of these readings by 10 in accordance with the range of modulation frequencies selected. In a modification, Fig. 8 (not-shown), the circuit of which the Q is to be measured forms the secondary of a loose transformer coupling between the mixer and detector.

Abstract: 420,234. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and COLLINGS, R. H. P., 4, Dean Place, Liskeard, Cornwall. May 26, 1933, No. 15297. [Class 40 (v)] A peak-voltage measuring instrument or indicator comprises a thermionic valve the internal impedance of which is varied in dependence upon the voltage applied to its control electrodes, the anode voltage controlling a gas-filled discharge relay between the cathode and anode of which is connected an auxiliary voltage, the flashing of the relay determining the voltage conditions applied to the instrument. The instrument can be employed as a modulation indicator, the applied voltage being rectified and the rectified voltage may supply a number of triode and relay groups flashing at predetermined percentages of modulation. The instrument can also, without a rectifier, be employed to control voltage levels on telephone transmission lines. A modulation meter comprises a pick-up circuit LC shunted by a potentiometer resistance P<1> connected through a rectifier V<1> to a triode V<2>, this circuit including an ammeter A and resistance R<1>. The anode circuit of the triode V<2> includes a variable resistance P<2>, the tapping on which is connected to a grid bias battery E<2> for a gas filled relay V<3>. The anode circuit of V<3> is connected to a separate source of alternating- current T. The circuit LC is first tuned to the unmodulated carrier as shown by maximum deflection on the ammeter A for distortionless working of the apparatus. On modulating, the tapping on P<2> is adjusted until the total grid bias on V<3> just causes the relay to flash. Modulation is then stopped and P<1> adjusted until flashing again occurs, the difference in current values expressed as a percentage of the original reading giving the measure of modulation.

Title: Improvements in or relating to the catalytic alkylation of paraffins and olefins
IPC: C07C2/60
Filed: 1943-09-17
Abstract: Aluminium chloride, isobutane, ethylene and hydrogen chloride or ethyl chloride are contacted at elevated temperature and pressure until all the metal halide is converted to a liquid hydrocarbon complex which is used as the catalyst in the productive phase of the process comprising feeding isobutane and ethylene, in a molar ratio of at least 2 : 1, with ethyl or hydrogen chloride to a reaction zone at 90-175 DEG  F. and 100-1000 p.s.i., a product containing 2,3-dimethyl butane being recovered. Ethyl chloride equivalent to 2-6 per cent by volume of the isobutane is the preferred promoter.  The activity of the catalyst may be periodically renewed by withdrawing part of the spent catalyst and adding a corresponding amount of aluminium chloride, e.g. about 1 lb. per 29 gals. of alkylate, followed by treatment with isobutane, ethylene and promoter to form the complex.  In examples, the complex is formed by reaction in a turbomixer at 150 DEG  or 110 DEG  F., the product being separated into an upper hydrocarbon layer and a lower layer containing the complex which is used for alkylation catalyst.  Results are given to show the improvement in octane number and yield after the complex has been formed as compared with the use of free metal halide.

Abstract: 258,018. Marks, E. C. R., (Barber-Colman Co.). June 15, 1925. Yarns, warping and beaming.-The yarns from the cheeses a of a warping and beaming apparatus are guided in their passage from the V-shaped creel, Fig. 2, solely by electric stop-motion detectors mounted on the pivoted gates 12 of the creel. The yarns pass below a guide-rod, through a warping comb 244, and over a roll to the section-beam B. The spindles in each section of the creel carry four cheeses, and each gate 12 comprises four tubes 26. Each detector comprises a looper wire 27 pivoted in the tube 26 at 28, Fig. 8, and normally held by the yarn 29 against a stop rod 30. The rod 30 connects plates 34, 32 on either side on the detector, the latter being mounted on the tube and carrying also a plate 31 situated between the legs of the detector. In preparing the machine, the yarns from each column of cheeses are drawn to the bottom of the creel and twisted together; the gates are then closed, and the bunches of yarns are drawn through the gates in contact with the respective tubes 26 towards the warping apparatus, and during this movement, the yarns are automatically guided up the plates 32, 34 to the detectors, which are pushed up against their respective stop rods. An electric conductor 37 in each tube is connected above the gate to a conducting strip 38, Fig. 10. A wire 39 is wound between insulating sleeves 40, 41, surrounding the upper pivot 19 of the gate, and connects the strip 38 to a terminal 42 from which a lead passes to the stop-motion device. The detector pivot 28 carries a wire arm 36 positioned by flats on the pivot. When the thread becomes slack, it is taken up by the detector moving between the plates 31, 32 and forming loops in the yarn. When the yarn becomes excessively slack or gives out, the detector falls to the position x, Fig. 8, and the arm 36 contacts with the conductor 37 to close the stop-motion circuit. To put a detector out of action when the creel is not filled, it is turned downwards from the position x, Fig. 8, forcing the arm 36 round on its flattened pivot through 180‹, when the detector may fall to the position y without closing the circuit. The gates are held closed by spring- pressed pivoted latches.
