Abstract: 1467013 Separating acetylenic hydrocarbons TENNECO CHEMICALS Inc 3 Sept 1974 [19 Sept 1973] 38492/74 Heading C5E Diacetylene and vinylacetylene are separated from a hydrocarbon pyrolysis gas containing 1-10 mol. per cent of such compounds by selective adsorption on activated carbon, the surface of which has been saturated, before contact with the pyrolysis gas, with an inert non- explosive compound having carbon adsorption characteristics similar to those of diacetylene and vinylacetylene, the adsorbed C 4  acetylenic compounds being desorbed by passing a stream of inert gas through the bed of activated carbon to form a gas stream containing 30-50 mole per cent C 4  acetylenic compounds in the inert gas. The inert non-explosive compound may be n-butane, isopentane, 2,2-dimethylpropane or ethyl chloride. Preferably the carbon is pretreated with 1-5% of n-butane in N 2  and is cooled to 25-60 C. before contact with the pyrolysis gas, or is treated with liquid n-butane which is allowed to evaporate thereby cooling the carbon. The pyrolysis gas may mixed with 30-70 wt. per cent of the inert compound before contact with the pre-treated carbon. The process may be adapted to separate C 3  and C 4  acetylenic compounds by passing the pyrolysis gas through two beds of activated carbon in series only the first of which has been pre-treated with the inert compound, the C 4  acetylenic compound being adsorbed on the first bed and the C 3  hydrocarbons (methylacetylene and alkylene) passing through the first bed but being adsorbed on the second bed. The inert gas used for desorbing the adsorbed acetylenic compounds may be steam or N 2  saturated with methylene chloride.

Abstract: 955,484. Hair driers. GENERAL ELECTRIC CO. Nov. 10, 1960 [Nov. 12, 1959], No. 38623/60. Heading A5R. A hair-drying bonnet comprises inner and outer flexible walls 3, 4, having an elastic band 9 at the bottom and being connected together at spaced locations to define air distributing channels 11, 15, a ring 22 to space the bonnet from the head and air discharge openings in the inner wall. An air supply pipe 2 is connected with an aperture in the outer wall. The walls are made of vinyl plastic sheet, the walls being heat-welded together along longitudinal lines 12 and a circumferential line 10 to define the channels. The portion between the circumferential welding line and the bottom edge in use forms a barrier to prevent air blowing over the face and neck from within the bonnet. The open top of the bonnet may be pleated and its size adjusted by a drawstring. In an alternative construction the channels are defined by spot-welding the inner and outer walls together.

IPC: H01Q19/28
Filed: 1973-08-16
Abstract: 1375680 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 16 Aug 1973 [16 Aug 1972] 38719/73 Heading H4A A directive beam aerial arrangement comprises a central driven monopole element P, Fig. 2, and S sets of parasitic elements, each comprising one reflector and p directors, arranged in respective radial planes at angular spacings of # = 360 degrees/S. The elements are disposed normally to a circular metal ground plate, and they have heights of approximately a quarterwavelength at the operating frequency. A feed source is connected between the base of the driven element and the ground plate, and a diode 2, Fig. 3, is connected between the base of each parasitic element and the ground plate. By applying suitable bias voltages through a choke 3 the diode 2 may either be rendered substantially non-conductive, when the associated parasitic element is ineffective, or said diode may be rendered conductive, when the associated parasitic element becomes effective. As shown, three directors are provided in each radial plane, as well as a reflector. The beam from the aerial arrangement may be directed along any of said planes, by rendering the diodes associated with the parasitic elements therein conductive. Additional directivity may be obtained by making other directors effective, as shown in Fig. 4. Here, as well as the reflector R 1  and the directors D 1 , D 2 , D 3  along the beam axis, directors A, A<SP>1</SP>, B, B<SP>1</SP>, C, C<SP>1</SP>, are made effective. The reflector and the additional directors all lie approximately along a parabola which has P as focus. A control arrangement for providing step-by-step rotation of the beam is described with reference to Fig 7 (not shown). This comprises an S-stage shift register, which is stepped by clock pulses and is re-set by means of a flipflop connected to its first and last stages. Output from each stage of the shift register is utilized for biasing the diodes of the associated parasitic reflector and director elements. Since each director is used three times during each beam rotation, i.e., once when it is in line with the beam axis, and twice when it forms part of a parabolic reflector (Fig. 4), outputs from three stages of the shift register are coupled through an OR-gate to each director diode.

Title: Automatic braking control system
Inventor: BINGEN ROALD
IPC: H01F27/40
Filed: 1959-11-16
Abstract: 899,863. Automatic braking systems. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Nov. 16, 1959 [Nov. 17, 1958], No. 38762/59. Class 105. In an automatic braking system for railway vehicles based on the linear relationship between the square of the vehicle speed under constant deceleration and the distance travelled, a signal is produced on the vehicle which is a function of the square of its speed and this is continuously compared with a signal representing the square of the speed limit for the vehicle, which will ensure that it will stop in a predetermined distance, to produce a difference signal which controls the braking of the vehicle. At each of a number of points on the track section over which the vehicle is retarded a signal is transmitted to the vehicle from track apparatus which initiates a signal thereon which is a function of the square of the speed limit at that point and on this signal is superimposed a second signal which varies with the distance travelled by the train to produce a continuous speed-limiting signal which decreases proportionately to the distance to be travelled by the vehicle and which is corrected at each track signalling point. A signal v which is a function of vehicle speed is produced by a tachometer 1 and applied via a squaring circuit 2 to a comparator 13. As the vehicle passes over a track signalling point a voltage from the sources 5-8 proportional to the square of the limit speed V2(1-4) at that point is introduced into the circuit 4 by the operation of one of the contacts 9-12 and on this voltage is superimposed a voltage u which is a function of the distance travelled by the vehicle derived from circuit 3 in which the voltage v is integrated. The combined signal c is compared in the circuit 13 with the voltage proportional to v<SP>2</SP>. The difference voltage f is used to control the braking of the vehicle.
