Title: A process for the production of gasoline from kerosene and like hydrocarbon oils
IPC: C10G11/02
Filed: 1920-03-17
Abstract: 165,167. Trotter, J. W. March 17, 1920. Hydrocarbons, cracking.-In obtaining gasoline from kerosine or other partially-refined paraffin oils, the oil is forced through a perforated copper pipe which exerts a catalytic action into a still kept under a pressure of 75-100 lb. per sq. in. and at a temperature of 500-700‹ F. Kerosine, after purification by treatment with fuming sulphuric acid, is heated by admixture with gasoline vapours at 1100-1200‹ F. and is pumped through a perforated copper pipe 71 into a still 69, Fig. 3, heated by burners 271. The vapours from the still are passed either to a condenser or to a second still for further treatment. The residue in the still is treated with superheated steam injected into the vapour space through a perforated pipe 70, and with heated gasoline vapours injected through pipe 71. Further treatment of the vapours is effected in a still 65, Fig. 5, heated by burners 274 and protected by a sand jacket 272. The vapours enter by perforated pipes 185 and rise in contact with nickel-plated steam coils 246. The second still is maintained at a pressure of 50-60 lb. per sq. in. and at a temperature of 800-850‹ F. The vapours from the second still may be treated in a similar still maintained at 40-50 lb. per sq. in. and at 900-950‹ F. A plant comprising two stills for initial treatment and two stills for further treatment, together with condensers, storage, purifying and filtering tanks, superheaters for steam and gasoline vapours, &c. is described.

IPC: G05D23/24
Filed: 1968-02-19
Abstract: 1,191,363. Automatic temperature control systems. PAVELLE Ltd. Feb.12, 1969 [Feb.19, 1968], No.8014/68. Heading G3R. In a temperature control system a solid state temperature sensitive element and an electronic control circuit are capsulated in a compound to form an integral unit. The sensor may be a thermo-electric element or thermistor 1 connected in a bridge network 8-11 across one diagonal of which is connected one transistor T1 of a complementary pair T1, T2 the latter gating a firing potential to a controlled rectifier 2 e. g. a thyristor or triac in series with a heater 3. Alternatively full mane rectification may be employed. A Zener diode 6 in a series with a resistor 7 stabilises the voltage across the control circuit at about 12 volts D.C. The components may be housed in a cylindrical tube of plastics or stainless steel 0.5 inch diameter and 10 inches long having a closed end the components previously being arranged on a printed circuit board in a mould into which an epoxy resin plus a setting agent and possibly a loading of silica flour is poured. The thermistor should be thermally insulated from the other circuit components and if the heating element is also included in the tube this should be thermally isolated also. The potentiometer 11 may be mounted at one end of the tube or separately, and in the latter case the tube may be arranged with sealed and sheathed cables for total immersion in say a photographic fluid bath.

Title: Improvements in or relating to the sorting of articles
IPC: B07B13/00
Filed: 1960-03-07
Abstract: 979,341. Separating solid materials. G. M. BAIGENT. March 7,1961 [March 7, 1960], No. 8020/60. Heading B2H. A method of sorting articles, e.g. stones and beans, in accordance with a physical property thereof, such as hardness, density or elasticity, consists in sensing the quality of impact as an article impinges on a target element, and determining the path of movement of the article as it leaves the target element, according to its quality of impact. In Fig. 2 articles fall from a hopper 9 on to a target element 10 of a sensing device 11, and articles having one quality of impact pursue the path 13 and are received in a bin 14 whereas articles having another such quality are deflected by an electromechanical or electropneumatic means 15 to a path 16. The said quality may be sensed by a transducer coupled to the element 10 so that movement thereof on impact generates a signal pulse ; or the transducer may be in the form of a microphone adjacent the element so that the sound of impact generates a signal pulse. In either case the pulse represents the quality of impact and hence the physical property of the article under examination. The pulses are fed to a discriminator feeding an amplifier controlling a trigger circuit which operates the means 15. In Fig. 3 the device 15 is omitted, and the path determining means is constituted by the target element 10 itself, which may be in the form shown in Fig. 4. In this form a slidable sleeve 21 in a casing 20 has a resilient diaphragm 27 receiving the falling articles, and a microphone 28 is connected to a circuit controlling a supply to a solenoid 30 which may, by attracting an armature 31 on the sleeve, move the sleeve to the left and thereby impart a "kick" to a striking article to deflect it from a particular path. In a modification a casing supports a diaphragm mounted on a pivoted member, movement of the latter being controlled by an electromagnet. The diaphragm is connected to an electromechanical transducer which feeds a circuit controlling the energizing of the electromagnet, and hence the movement of the diaphragm. In Fig. 7 stones and peas are fed by a conveyer 60 and shoot 61 to rows of target elements 62, 64-66 ; stones are deflected to paths 66 and peas follow the path 63.

Title: Variable frequency oscillator with mechanical volume equaliser
IPC: H03L5/00
Filed: 1941-06-27
Abstract: 549,537. Valve generating circuits. STANDARD TELERHONES &, CABLES, Ltd. June 27, 1941, No. 8106. Convention date, July 3, 1940. [Class 40 (v)] In an oscillator, the means for varying the frequency is coupled to means for varying the screen potential of a valve in such a way that the output is constant: throughout the 'frequency range. Fig. 1 shows an arrangement in which the requisite frequency is obtained by mixing the outputs of a fixed oscillator FO and a variable oscillator VO in a modulator M, the output of which is filtered at F and amplified at A. The frequency of oscillator VO is varied by means of dial 17 controlling condenser Cv which is coupled by cam 18, and members 16, 15 to a potentiometer 10 in the screen grid circuit of the oscillator FO. Cam 18 is designed so that variations in the output due to change in frequency are compensated by variations in the screen grid potential and hence the output of the oscillator FO.

Abstract: 1307802 Model aircraft C J GREEN 30 March 1971 [30 Jan 1970] 8186/71 Heading B7W [Also in Division F1] A model aircraft having a body 11 and wings 12 is powered by a jet propulsion engine 13 using Freon (Registered Trade Mark) as the working fluid. After launch the thrust of the engine is insufficient to maintain sustained climb of the aircraft so the latter levels out and , then goes into a dive as movement of the liquid Freon causes the centre of gravity 35 to move forwardly. As the dive speed increases the wing lift increases so the aircraft pulls out and again goes into a climb with movement of the c. of g. 35 rearwardly. This sequence continues until, when all the Freon has been exhausted and the c. of g. 35 is in line with the centre of pressure of wings 12, the aircraft goes into a level glide.

Abstract: 557,175. Packing. ROSE. A. G., and ROSE BROS., (GAINSBOROUGH), Ltd., June 30, 1942, No. 8983. [Class 94 (i)] A method of forming a package of substantially rectangular form consists in moving a wrapper through a guide channel by means of the article to be wrapped to form an openended pouch, folding and sealing the side flaps of the wrapper as it is moved, completing the folding of the open end, and finally transferring the packet on to a preformed blank on a conveyer arranged transversely to the guide channel. The method is intended particularly for packing batches of cigarettes in transparent cellulosic material of the kind which is rendered adhesive by heat, the sealing of the overlapping edges of the wrapper being effected by contact with heated tools. Cigarettes are fed longitudinally from a hopper 11 in a succession of batches 12 each of which is moved forward along a guide channel 17 by a pusher 18 attached to conveyer chains 19. Before entering the channel 17, the batch encounters a strip 21 of cellulosic material, and this strip is carried into the channel 17 and in so doing is folded around one end and the front and back of the batch. The side edges of the wrapper are folded by fixed folders 23, and the overlapping side edges of the folded wrapper are sealed to one another as they pass heated sealing- elements 24 which are pressed resiliently against the side of the batch. The batch, now enclosed in a pouch with one end open, comes to rest at an end-folding station where the pusher bar moves away in the manner described in Specification 4,19,619. [Group XXX]. The open end of the pouch is new folded by side tuckers and end folders 27, 28, as described in Specification 489,935. The packet is next transferred by the folding member 28 into one of a series of open-ended packets 36 carried by a chain conveyer 37, each packet containing a preformed blank 38 which later is formed into the slide of a slide-and-shell carton. The folded end of the wrapper is then pressed and sealed by a heated sealing-member 39 as the packet is conveyed to the mechanism for completing the slide and shell carton.
