Patent GB-1302839-A (GB)
IPC: F28D17/00
Filed: 1969-12-05
Abstract: 1302839 Heating and cooling buildings THERMO-BAUELEMENT AG 5 Dec 1969 [8 Jan 1969 3 Feb 1969(2)] 33678/72 Divided out of 1298674 Heading F4U [Also in Division E1] A building panel comprises an enclosed hollow body filled with a heat insulating gaseous or vaporous medium and control means are provided for varying the thermal conductivity of the medium so that the panel may be used to heat, cool or insulate a building structure. As described a panel 60, Fig. 1, encloses a layer of thermal storage material 62 resiliently supported on foamed material or air filled tubes 63 and parallel flexible ducts 67, 68 are formed between the material 62 and an outside wall 66 of the panel, to which ducts gas under pressure is fed by control means (not shown). In use, the gas pressure is controlled in the ducts to vary the thermal conductivity of the panels. In a further embodiment, a building panel 232, Fig. 2, is sealed and has parallel ribs or fins 231, 236 on the inner faces of the panel walls. A perforated plate 235 is suspended from electromagnetic vibrators 234 between the fins. A heat storage material layer 230 is combined with the panel. In use, maximum heat insulation is achieved by still air within the panels but by varying the amplitude and frequency of vibrations of the plate, the air turbulence is altered and hence thermal conductivity. In a further embodiment a surface 130, Fig. 5, of a hollow building panel forms a heat sink behind which a thermal storage panel 132 of crystalline material is positioned. The panel is filled with the saturated vapour of a low-boiling heat carrier which at operating temperatures is condensed at the cold surface 133 of the panel to be collected in a channel 136 which is shut off from a space 134 above the panel 132 by a bimetallic-controlled valve 137 so that the evaporation-condensation cycle may be controlled and hence thermal conductivity of the panel regulated. The thermal storage panel 132 may withdraw heat from the room of a building during day-time and yield it to atmosphere at night. In summer the panel acts to maintain a room at a cool temperature, and in winter to insulate the room. Condensate is distributed uniformly over the panel 132 by the capillary action of an absorbent paper layer 138 above which a space 134 is filled with a permaeble porous insulating material.

Title: Improvements in or relating to a method for providing golf balls with a wear resisting surface
IPC: C08J7/046
Filed: 1932-11-29
Abstract: Moulded golf ball shells, vulcanized or unvulcanized, are treated with a halogen element or elements, to facilitate adhesion of paint thereto.  The halogen elements may be used in admixture or chemical combination, and in gas or vapour form or dissolved in a solvent such as water, ethylene dichloride, chloroform, glacial acetic acid, the solvent in some cases being one which will retard the treatment.  A mixture of solvents may be used, for example, ethylene dichloride with ethyl acetate or carbon tetrachloride or carbon disulphide with glacial acetic acid.  The halogens may also be used in conjunction with a halogen derivative of a non-metallic element such as sulphur and the reaction of the halogens with the rubber and/or guttapercha ball may be stopped by treatment of the ball with an antichlor solution, such as, sodium thiosulphate, sodium sulphite, or sodium nitrite.  In one example, a ball is immersed for a period of from 1/2 to 5 minutes in a saturated solution of chlorine in a mixture of glacial acetic acid, 80 parts, ethylene dichloride 30 parts and sulphur dichloride 1 part.  The ball is then washed in alcohol for 1 minute, then in an antichlor solution for 1 minute and finally in running water for 30 minutes.  The treated ball is then dried and allowed to stand at room temperature for 20 hours after which it is ready for painting.  Other examples are described wherein halogens in admixture or chemical combination are used.
Patent GB-337775-A (GB)
Abstract: 337,775. British Thomson-Houston Co., Ltd., and Johnston, A. J. April 30, 1929. Totalizators.-In a totalizator system, applicable to electric integrating meters, multidenominational bet impulses are transmitted to counter switches over rotary commutators, the transfer impulse from any counter passing to the counter for the next higher denomination by way of the rotary commutator related to the latter denomination. The contacts of the transmitters (rotary commutators) A, B, C and D corresponding to 2/-, ú1, ú10 and ú100 bets are in circuit with contacts 9, 38 ... which are closed when a ticket is issued at a corresponding machine. The arms of these commutators are continuously rotated and when the arm 7 (say) of the 2/- transmitter passes over bank contacts 6 marked by a closed contact 9 the notch relay 11 is actuated to step the 2/- counter E comprising the rotary switch banks E1, E2, E3, E4; and so on for the other denominations. Transfer mechanism. On the ninth step of the relay 11 a relay 41 is energized over bank E1 to open normally closed contacts 43, 45. When the tenth 2/- bet is collected, relay 41 releases, and the magnet 42 being "slow" a momentary circuit is made over contacts 45, 44 to operate relay 46 which locks, up over contacts 49, 48, the contact 50 marking, over lead 13, the contacts 34 of the transmitter B. When the arm 35 reaches a contact 34 the notch relay 15 is energized and actuates its associate counter F comprising banks F1 F2, F3, F4 to register a ú1 bet. At the same time the arm 36 of the bank B2 passes over a contact 37 whereon an impulse is sent through the relay 47 which breaks contact 48, resetting the relays 41, 42, 46, 47 for the next transfer. Transfer between ú1 and ú10 denominations is identical, but for transfer to the ú100 counter a relay 25 is energized on the tenth step of counter G1, G2, G3, and locks up over its contact 28. The transfer. impulse is sent to transmitter D1 over contact 27, the release of relay 25 being effected by relay 31 on its intermittent energization through the commutator D2. The various counters G, H, I, for ú10, ú100, ... are duplicated by means of counters K, L, M, N driven in synchronism with the former, their driving magnets OM, being operated over second contacts of the relays 21, 63. As no tickets of value above ú100 are issued transfer to the counters I, J, M, N is direct. Each counter has a resetting wiper, E3, E4; F3, F4; G2; K2; ... &c. being zeroized when contacts RR are closed by a reset re:lay. The ú10 and higher denominational counters have each banks G1, H1, ... &c. from which monogrammic lamp indicators may be actuated. Reference has been directed by the Comptroller to Specification 329,631.

Title: Automatic control of machinery by bands of paper and the like
IPC: G03B27/16
Filed: 1937-12-08
Abstract: 507,073. Photographic printing-apparatus. I. G. FARBENINDUSTRIE AKT GES. Dec. 8, 1937, No. 33981. Convention date, Dec. 14, 1936. [Classes 98 (i) and 98 (ii)] For automatically controlling machinery with the aid of an intermittently advanced control band, each factor or quantity to be controlled ia determined by the distance of a mark provided on the band from a predetermined datum line, for example, the beginning of a new control section of the band, which datum line is perpendicular to the direction of movement of the band relative to a scanning or feeler device adapted to be affected by the mark. In the band shown in Fig. 1, the effective distances are the distances b ... g, from a line A-A, of a number of apertures located, on lines 1 ... 6. When a different set of conditions occurs, the band is advanced and the various factors readjusted to correspond to a fresh set, of distances b<1> ... g<1> from a line A<1>-A<1>. In the arrangement shown in Fig. 2, the band moves over a plate 11 provided with a toothed surface 16. The devices to be adjusted are coupled to rods 7 each of which has a projecting pin 20 acted on by a spring 18. A bolt 23 sweeps all these pins forward, as the crank 24 is operated, until the trailing pawls 17 reach the far end of the control section of the band, and is then released. The rods 7 are retracted by the springs 18 until the pawls drop through apertures in the band and are engaged by the teeth 16, thus bringing the rods 7 to rest in positions corresponding to the positions of the apertures in the band. The control band is fed forward during this setting operation by the arm 26, the end of which strikes pin 27 carried by the sprocket 13, which is thereby rotated. As applied to photographic copying apparatus, the rods 7 may bring field lenses into or out of operation or may operate a Venetian blind screen for adjusting light intensity. Specification 497, 753 is referred to.

Abstract: 1,020,996. Hydrostatic gear control. SOC. INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE S.I.G.M.A. Aug. 29, 1963 [Sept. 15, 1962], No. 34255/63. Headings F2C and F2D. A hydrostatic transmission for a vehicle comprises an engine driven variable displacement pump 2 connected through a flow dividing valve 12 to two fixed or variable displacement motors 4, 4a which drive vehicle wheels 5, 5a and auxiliary pumps 18, 18a delivering liquid to chambers 20, 20a at the ends of the flow dividing valve 12, the outlets 25, 25a of which chambers 20, 20a are controlled by a manually operated throttle valve 24. During normal operation, with the throttle valve 24 in the central position shown, the pressures in the chambers 20, 20a are equal and the valve spool 12 is centred by springs 27, 27a to provide equal flow through each motor 4, 4a. If a pressure differential occurs in the chambers 20, 20a due to one wheel slipping, the flow dividing valve spool 12 is automatically moved by the differential pressure to alter the fluid flow to each motor and thus counteract this differential. Manual movement of the throttle valve 24 creates a pressure differential in the chambers 20, 20a and causes movement of the flow divider valve spool 12 to alter the flow to each motor and produce a speed differential between the wheels 5, 5a to steer the vehicle. For a vehicle with a train of non- steerable wheels as endless tracks the throttle valve 24 may be connected to a steering control lever 29 whilst for a vehicle having steerable wheels and a train of non-steerable wheels or endless tracks the valve 24 may be operated by the control for the steerable wheels.

Abstract: 919,734. Friction clutches. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 22, 1961 [Oct. 6, 1960], No. 34321/60. Class 80 (2). In a centrifugal mechanism, such as that for actuating a disc clutch, centrifugal weights are associated with axial thrust transmitting means in such a way that the mechanical advantage of the arrangement, defined as the ratio of the axial force to the centrifugal force, first decreases with increase of speed of rotation through a lower speed range and then increases with increasing speed through a higher range so that the mechanical advantage is a minimum at a speed representing the upper end of the lower range and the lower end of the upper range. In the arrangement shown, pivoted clutch weights 13 bear against rollers 17 on the pressure plate 10 through cam-shaped nose portions 16 giving the desired operating characteristics. Alternatively, radially operating weights may move between appropriately shaped surfaces on the cover and pressure plates. The invention may also be applied to centrifugal governors.

Filed: 1937-12-13
Abstract: 507,567. Gas manufacture. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Dec. 13, 1937, No. 34454. [Class 55 (ii)] [Also in Group IV] Gaseous olefines are obtained from the products of the catalytic hydrogenation of carbon monoxide, the constituents of which contain more than one carbon atom and may or may not contain oxygen, by leading them at elevated temperature with hydrogen over a hydrogenation catalyst and cracking and/or dehydrogenating the resulting hydrocarbons. The initial products may be led with hydrogen at 180-200‹ C. and ordinary or elevated pressure over metals of Groups 6 to 8 or their compounds, e.g. nickel on carriers. The subsequent crackling is effected in known manner, e.g. at above 700‹ C., using apparatus inhibiting carbon deposition, e.g. comprising coatings of silicon or titanium or chromium steels as described in Specifications 403,647 and 469,101, [both in Group III], respectively. The products may be separated, liquid products being returned to the hydrogenation or constituents boiling at 80-120‹ C., mainly aromatic hydrocarbons, being removed. Gaseous products may be treated to remove acetylenic compounds, olefines then being separated with ammoniacal cuprous salts. Ethylene may be separated by pressure distillation, and the higher olefines hydrogenated as described in Specification 506,832, [Group IV], and wholly or in part subjected to cracking or dehydrogenation. In an example, an oil obtained from CO and H2 is hydrogenated at 200‹ C. and 180 atmos. using a nickel-alumina catalyst, and led with cracking gas through a packed tube of chromium steel at 750‹ C. A gas of the percentage composition : ethylene 35, higher olefines 20, hydrogen 10, methane 30, methane homologues 5, and an oil containing benzene hydrocarbons are obtained.
