Title: Apparatus for indicating movements of the centre of gravity of aircraft
IPC: B64C25/00
Filed: 1932-05-13
Abstract: 387,887. Indicating position of centre of gravity of aircraft. ADAMS, D. R., 27, Mowbray Road, Edgware, Middlesex, and ALLEN, T. G., 6, Albert Court, Kensington Gore, London. May 13, 1932, No. 13845. [Class 97 (iii).] To indicate deviations from the designed centre of gravity of an aircraft, weighing mechanisms are interposed between the ground and points of support of the aircraft, and means are provided for indicating changes in the relationship between the weights carried by the individual weighing mechanisms or by chosen groups of weighing mechanisms. The weighing mechanisms may comprise fluidpressure devices built into the undercarriage and tail wheels or skid of the aircraft. In the form shown a piston 1 attached by a rod 2 to the wheel axle 3 works in a cylinder 4 which is mounted to slide against the tension of a spring 7 in a cylindrical guide 5 attached to the aircraft body by struts 6. The cylinder 4 is filled with oil and communicates through pipes 8, 9 with the indicating device. A similar hydraulic device is arranged to carry the weight transmitted to each of the wheels of the undercarriage and also to the tail skid. The indicating device, Fig. 3, comprises a lever arm 21 carrying pointer 25 and pivoting on an adjustable fulcrum 24. A rod 22 attached to a piston 23 working in a cylinder 17 in communication with the cylinder above the tail skid, thrusts against one end of the lever 21 and a rod 20 carrying two pistons 19 working in cylinders 18 communicating respectively with the two cylinders 4 above the wheels of the undercarriage thrusts against the other end. The movements of the lever 21 may be spring retarded in both directions.

Title: Improved process for making decorative panels
IPC: B44C3/04
Filed: 1942-10-02
Abstract: A process for producing a decorative, advertising or display panel consists in forming a die with a design thereon in relief or intaglio, transferring the design reversed to thermo-setting plastic material, and using the negative thus produced as a mould or as an impressing or embossing die for reproducing the design. The design may be thus reproduced in plaster of Paris, clay, powdered resin or resin solution plus siliceous material (by using the negative as a mould) or in papier mach<\>ae, leather, plastic wood, resin-impregnated paper or fabrics (by using the negative as an embossing die).  The die may be of hard steel formed from an original drawing by photo engraving, and the negative may be produced therefrom by setting the die in a frame and pouring over it partly-cured semi-liquid phenol-formaldehyde condensate or heat-hardening glue and heating the latter, with pressure if necessary.  The hard steel die may be covered with chromium when urea compounds are used, to prevent chemical interaction.  The reproduced design may be coated or filled with clay, enamel or paint.  The original metal die and the negative produced therefrom can be used in combination to impress the design on thin material, if thin material or an oil film is interposed between the die and negative when the latter is being made.  Specification 554,529 is referred to.
Patent GB-378105-A (GB)
Title: Improvements in or relating to electric time switches
IPC: G05D23/275
Filed: 1931-05-11
Abstract: 378,105. Time switches ; thermal switches. HALLETT, C. G. H., Minto, Chestnut Avenue, Esher, Surrey, and MORGAN CRUCIBLE CO., Ltd., Battersea Works, Church Road, London. May 11, 1931, Nos. 13916/31 and 7213/32. [Class 38 (v).] A desired temperature or pressure is produced at a predetermined time by means of a switch comprising two co-operating contacts, one of which is actuated by a temperature-sensitive or like element and the other by a clockworkdriven cam. In the form shown the contact 2 is actuated by an expansible bellows 8 against the action of a spring 10 and co-operates with a contact 3 actuated by the clockwork-driven cam 1 to close a circuit to a relay 16 which switches heaters 19 on or off, the arrangement being adapted to heat a school room to a definite temperature at a given time in the morning, to keep it at this temperature during the morning, to switch off the heaters during the midday interval, to heat up the room again for the afternoon session and to retain it at the required temperature during the session, the heaters finally being switched off. This is all achieved by shaping the cam, which rotates once in twenty-four hours, as shown. A stop 14 prevents the engagement of contacts 2, 3, no matter how low the temperature, when the pin 12 which engages the cam rests on its narrowest portion. In modifications the relay 16 is replaced by a relay which permanently closes the heating circuit as soon as it is actuated, and the heater may then be automatically switched off at a later time by means of a third contact 13 engaged by the contact 3. The strip 4 may also be bimetallic or coupled to a bimetallic strip. In another modification the contact 2 is controlled by a thermopile and relay and in another the temperature and time controlled contacts move along the arms of a Wheatstone bridge the usual galvanometer of which is replaced by the relay 16.
Patent GB-715316-A (GB)
Title: Improvements in or relating to the separation of volatile components from mixtures containing pitch, by distillation
Inventor: DUMMETT GEORGE ANTHONY
IPC: B01D1/22
Filed: 1950-06-06
Abstract: <PICT:0715316/III/1> Volatile components are separated from liquid mixtures containing relatively non-volatile material, such as pitch, by causing the liquid mixture to flow by gravity in the form of a thin film over a heated surface at a pressure of 10 to 100 mm. Hg., and subjecting the film to contact with steam.  The temperature conditions are selected with regard to the nature of the mixture so as to effect volatilization of the volatile components without causing polymerization of the volatiles or decomposition of the relatively non-volatile material.  The process is applicable in the distillation of unrefined tall oil, crude tar acids, coal tar, acid-washed benzole, gasoline, and naphthalene.  Falling-film type evaporator 1 comprises vertical tubes 3, 31 housed in a jacket 4 through which a heating medium, such as steam, hot oil or Dowtherm, is circulated via pipes 5, 6.  The open upper ends of the tubes project into chamber 8.  Steam injection pipes 2, 21 enter the upper ends of the tubes.  The liquid to be treated is supplied to chamber 8 through pipe 7; and flows from chamber 8 down the tubes, wherein it is partially evaporated.  The vapours together with the non-volatile components are discharged from the lower ends of the tubes into sump 9, which is connected to centrifugal separator 10.  The liquid separated in the separator is returned to the sump via bypass 11. The vapours are passed via line 12 to condenser 13, which is connected to a vacuum pump.  The liquid in sump 9 may be recycled. In an example, crude tar acids containing phenols, cresols, xylenols, water (10 per cent.) and pitch (55 per cent.), are distilled under an absolute pressure of 50 mm. Hg., the mean temperature in the tubes being 115 DEG C.  In this case the water content of the mixture provides the steam to contact the film.  A high yield of volatile constituents, and a pitch having a softening point of 110 DEG C., are obtained.  In another example, crude tall oil is supplied to the evaporator, together with 1 lb. of steam per gram of oil.  The tubes are maintained at about 170 DEG  C., and the absolute pressure at 30-40 mm.  Specification 703,476 is referred to.

Title: Improved polyolefin articles
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: D01F6/20
Filed: 1960-04-22
Abstract: Shaped articles having improved dye-affinity are produced from polyolefins by shaping a composition containing a polyolefin and a compatible, covalent polymer containing acid halide groups, characterized in that the acid halide groups are treated to convert them to the corresponding free acid, salt or amine groups The polyolefin may be derived from ethylene and/or propylene and the covalent polymer may be phosphochlorinated polypropylene, phosphochlorinated polystyrene or a phosphonitrile halide. Treatment with water gives acid groups and with alkali gives salt groups, thus producing affinity for basic and disperse dyestuffs. Treatment with a nitrogenous base gives amine groups having affinity for acid dyestuffs. The compositions may be shaped into filaments, fibres or films. Specifications 810,023, 881,981 and 907,765 are referred to.

Title: Purification of olefin polymers
IPC: C08F6/06
Filed: 1962-04-13
Abstract: Solutions of olefinically-unsaturated polymers in hydrocarbon solvents which contain an insoluble gel by-product are purified by emulsifying the solution with sufficient water to cause the specific gravity of the emulsion to be greater than that of the gel, separating the gel from the emulsion and recovering the polymer.  The water may contain a surfactant and/or a chelating agent. The polymer is recovered by breaking the emulsion e.g. by heating the emulsion to a temperature in excess of 150 DEG F.  The polymers are preferably prepared with Ziegler-Natta type catalysts.  The polymer may be polypropylene, or a copolymer of ethylene and propylene.  The surfactant may be an alkyl phenol-ethylene oxide condensate, or a condensate of ethylene oxide with fatty alcohols or acids or resin acids, or tall oil. Specified chelating agents are citric acid, oxalic acid, or ethylene diamine tetraacetic acid.  The polymers may be vulcanized or cross-linked using conventional techniques.

Title: Improvements in motor cycle change-speed gearing
IPC: B62M11/06
Filed: 1931-05-19
Abstract: 371,188. Controlling motor-cycle changespeed gearing. ELITEDIAMANTWERKE AKT.-GES., Erbisdorf, Brand, Saxony, Germany. May 19, 1931, No. 14737. Convention date, Aug. 23, 1930. [Class 79 (v).] In a motor cycle in which the change-speed gear is controlled by two pedals one for each foot, each pedal is locked in the neutral position as long as the other pedal is in the operative position. In the construction shown the gear box 1 has four speeds and is controlled by right and left pedals 6, 5, having stirrups 10, 9 acting on arms 14, 13 fixed to gear-controlling shafts 12, 11. The pedals are rocked fore and aft about their shafts 8 each pedal controlling two speeds. The pedal stirrups 10, 9 are slotted at 16,15 so that when the gear box is moved longitudinally along slots 4 to adjust the chain the connection between the pedals and the arms 14, 13 is not affected by this movement. The shaft 11 carries arms 27, 28 connected to a sliding clutch fork 31 which moves a clutch sleeve 25 into engagement, either with clutch teeth 19 for the direct drive or third speed, or with clutch teeth on a pinion 18 for the second speed. The shaft 12 similarly controls a clutch fork 32 and clutch 26 which can engage either the first or low-speed pinion 17, or the fourthspeed pinion 20, the last speed being an " overspeed." The interlocking devices comprise shafts 33, 34 on which are fixed guiding pieces 35, 36 and locking arms 37, 38. The guiding pieces are adapted to engage and be engaged by members 39, 40, connected to the gear forks 32, 31 so as to slide therewith. When a gear fork 32, say, is operated to engage a gear the member 39 acts on the guiding piece 35 and rotates the shaft 33, thereby causing the locking arm 37 to rise and engage a notch 41 on the arm 27 connected to the clutch fork 31 so that the arm 27 and clutch 31 are prevented from moving. The clutch fork 32 is similarly locked by the arm 38 when the clutch fork 31 is operated. Springs 42, 43 act on the shafts 33, 34 and return the locking arms 37, 38 to the inactive position.

Abstract: 459,504. Coin-freed apparatus. DEAN, H., Mount Street Works, Mount Street, Notting- ham. May 21, 1935, No. 14767. [Class 27] Testing coins.-A device for preventing the insertion of unmilled coins into a coin-freed apparatus comprises a barrier 9 pivoted at 10 and normally obstructing the coin entrance. An inserted coin passes between a fixed milled inset 3, and a milled eccentric roller 4 secured to a shaft 5 journalled in a frame 6 pivoted at 7 to allow slight upward movement. If the coin is milled, it rotates the roller 4, and an arm 8 secured to the shaft 5 of the roller swings rapidly upwards, carrying with it the barrier 9 by means of an off-set part 14, so that full insertion of the coin is permitted, Fig. 5. If the coin is not milled, the roller 4 is not rotated, but is raised slightly with the frame 6 turning about its pivot 7: the off-set part 14 of the arm 8 binds against the front of the barrier 9 which consequently remains in a position to prevent full insertion of the coin, Fig. 6. Fraud, preventing.-Any attempt to rotate the roller 4 and raise the barrier 9, by means of a smooth coin or inserted instrument, is frustrated owing to the frame 6 first rising and causing the locking of the parts as shown in Fig. 6. The front face of the barrier 9 is concave to prevent raising of the barrier by the rotation of a smooth coin in contact with it.

Title: Encoding apparatus
IPC: H04L13/16
Filed: 1973-03-27
Abstract: 1427429 Encoding apparatus ADDRESSOGRAPH MULTIGRAPH CORP 27 March 1973 [30 March 1972] 14773/73 Heading G4H Apparatus for supplying data to a recording device 21 comprises a keyboard equipped with alpha-numeric data keys 20, and addressing keys 30 each used for accessing a plurality of consecutive character locations in a programmable memory 32. As described, device 21 provides a binary record on punched tape; alternatively, the recording may be, e.g. magnetic and/or on tapes or cards. Depression of a key 20 causes an encoder 22 to send a binary coded signal to a buffer 26 connected to puncher 21, the keyboard being inhibited until the data in 26 has been punched. Each key 30 corresponds to the address of the first of up to 64 consecutive locations in memory 32 which contain a message to be recorded. The provision of a shift key allows keys 30 to be " split " so as to represent up to two 32-character strings stored in first or second halves of their allotted character locations in memory 32. A key encoder 36 and a split key detector 37 place the key address in a register 41, whence it is fed to a comparator 40, and cause the register to set flip-flops 38, 39 according as the selected key was split and the shift key was up or down: the flip-flops cause a counter 46 to be set to 0 or 32 according as the required storage locations in memory 32 constitute the first or the second half (or both) of the storage space allotted to that key. The contents of memory 32 circulate via a circuit 52, the contents of the first character storage location also being copied into a shift register 54. The clock which shifts 32 also increments counters 42a-42c (counting bits, 8-bit characters, and 64 character locations). When the count in 42c equals the output from 41 and when the count in 42b equals the value in 46, a gate 45 causes a circuit 60 to set a flipflop 62 after an 8-bit delay to allow the contents of the sought character location to appear in register 54. The setting of 62 enables a gate 64 and the character passes to buffer 26 to be punched, 62 then being reset by a signal 67 and counter 46 being incremented by one so that the next character can be accessed. This continues until either counter 46 attains its maximum count or a code of all 1's is detected in 54-this corresponds to all 0's in memory 32 and indicates the end of a character string of less than maximum length. The above description relates to the read mode R. A detailed description is given with reference to Fig. 1 and Figs. 2-5 (not shown) of four other modes: (1) Memory 32 loaded from the keyboard (keys 20) tape punched with a " rub-out " code (all 1's) the key address, and the data stored. (2) Memory 32 loaded from a paper tape loader PTL 100; tape punched as before. (3) Menory 32 read out and a check tape prepared. (4) A tape prepared without loading or reading from memory 32.
