Abstract: 1,147,339. Moulding fluidic elements. INTERNATIONAL COMPUTERS Ltd. 5 Dec., 1966 [7 Dec., 1965], No. 51759/65. Heading B5A. [Also in Divisions B3 and G3] In a method of making a fluid logic element, a master element 1, Fig. 1, e.g. of soft metal such as brass, is first produced, tested and modified until it has the desired characteristics, an inverse pattern 20, Fig. 2, is then made from this master e.g. by the casting of an epoxy resin, plaster of Paris or type metal, and a copy of the master is made from the inverse pattern by a moulding process e.g. by casting an epoxy resin or type metal. This latter moulding process is repeated as desired. The inverse pattern of the master may be made by coating the master with a layer of metal and then dissolving the master, a reinforcing layer of resin or metal being applied to the metal layer. A network of separate fluid elements made as described may be assembled and interconnected by machined channels. The network may be moulded as a unit from an array of inverse patterns and their interconnections.

Title: Magnetic bubble domain chip
IPC: G11C29/00
Filed: 1974-12-05
Abstract: 1482998 Magnetic bubble devices INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1974 [28 Dec 1973] 52613/74 Heading H3B The propagation of a "scout" bubble through a magnetic bubble chip is monitored to determine the location of a fault and a magnetic switch is operated to cause subsequent bubbles to take a different path on the chip to bypass the fault. In the shift-register shown, a scout bubble generated at 14 is propagated through the first loop 1, the drive field reversed and the bubble magneto-resistively sensed at 44. The process is repeated through all the loops in series until the bubble is either not sensed at all or at the incorrect time, indicating that a fault exists in loop 3 (say). A bubble is then sent out to the beginning of the faulty loop and a conductor 22 pulsed to transfer the bubble to a permalloy retaining disc D3. Subsequent scout and data bubbles are repelled by the captured bubble and pass to the following loop via a Y-bar element 36-3. Continuously energized or synchronously pulsed switches may replace the permalloy discs. If a fault develops in use, the whole chip is saturated and the complete test programme repeated.

Abstract: 1,267,518. Indicating brake wear. SELF ENERGISING DISC BRAKES Ltd. 4 Nov., 1969 [6 Nov., 1968], No. 52665/68. Heading F2E. A device for indicating the operating condition of a vehicle brake; said device including, or consisting of, a first indicator electrically connectible to a first switching element, a second indicator electrically connectible to a second switching element, the first and second switching elements each being settable into a first state where electrical conduction therethrough is prevented or a second state where electrical conduction therethrough is permitted, each element being normally in its first state, and means for supplying electrical power only when the vehicle brake is operated, said means being connectible to the indicators and associated switching elements so as to be capable of energizing either of said indicators whenever its associated switching element is in its second state; wherein the first switching element is disposed in co-operable relationship with the brake so that it is set to its second state when brake adjustment is required and the second switching element is disposed in co-operable relationship with the brake so that it is set to its second state when excessive brake wear has occurred. In the example shown in Fig. 1, indicators 21-24, which may be lamps, movable arms carrying flags or devices giving an audible or both audible and visual signals, are mounted on a panel disposed in the driving cab of a vehicle, one terminal of each lamp being connected to the stop light S of a trailer and the other terminal of each lamp being connected to two-state switching elements 29-31 of the make-andbreak type and operatively associated with the brakes of the trailer. When the brake pedal is depressed an indication of the state of the brakes of the trailer is given. The circuit may have incorporated therein means for testing the indicators. In Fig. 3, the switching element comprises a stem 40 of electrically conductive material disposed in a brake shoe 42, the head of the stem being coated with a film 46 of insulating material; when the lining 44 and consequently the film have worn away the stem 40 is brought into contact with the brake drum to energize the associated lamp. In modifications, switching contacts are mounted on an axle housing and a cam-shaft, the latter being pivoted to apply the brakes associated with the axle and the contacts engaging when pivotal movement of the cam-shaft is large enough to indicate excessive brake wear, (b) the push rod of a pneumatic diaphragm for applying the brakes carries a contact which is engageable with a contact on an axle housing, and (c) a limit or micro-switch is mounted within a pneumatic diaphragm housing.

Abstract: 1397759 Multiplex pulse code signalling; exchange systems SIEMENS-ALBIS AG 16 Nov 1972 52875/72 Headings H4L and H4K A chain of P.C.M.-T.D.M. exchanges VA, VB, VC, VD is synchronized by insertion at appropriate exchanges of blind bits (stuffing bits) and the end exchanges VA, VD are further synchronized, if necessary, to permit use of a direct link between them by the use of additional (preferably higher frequency) blind bits at one or both of VA, VD. The exchanges are thereby connectable in a loop. Each exchange say VA has an input buffer store with a maximum delay time of #, so that a sync word start-bit Be1 Fig. 2(a)A, from an adjacent exchange, which arrives within the period # before the exchange's own start bit A;, may be delayed and thus synchronized with the exchange VA. If it arrives within a prohibited portion γ of the # period as does Ae1 at station VB, Fig. 2(a)B, the exchange VB generates a blind bit, to move its own frame later in time (to the right in Fig. 2) thereby causing Ae1 to fall in the permitted portion of #, Fig. 2(b)B. In this way, VB, VC are synchronized to the stations on either side of them sufficiently for the buffer stores to effect final synchronization. At VD however, the start pulse Ae2 is still outside the # period, and the extra higher frequency blind bits are generated at one or both of VA, VD to pull the two exchanges together. Whichever exchange senses that its received sync word bit (say Ae2) is relatively unmoving compared with its own Di, under the action of the "normal" blind bits, generates the additional blind bits. If more than one exchange needs to generate additional bits, their frequencies must differ.

Abstract: 1364727 Unsaturated carboxylic acids and esters ROUSSEL UCLAF 15 Nov 1971 [13 Nov 1970] 52897/71 Headings C2C and C2P 3,11 - Dimethyl - 7 - ethyl - trideca - 2,6,10- trienoic acid and alkyl (C 1-5 ) esters thereof are prepared by reacting triphenyl 4-methyl-5- carboxy - pent - 4 - enyl phosphonium halide with 7 - methyl - non - 6 - ene - 3 - one in the presence of a strong base to form the acid which may then be esterified. The strong base may be an alkali metal alkoxide, e.g. potassium tert.- butoxide, reacted in a polar solvent such as dimethyl formamide. The ester may be formed by reaction with a diazoalkane, e.g. diazomethane in an organic solvent. The 7-methyl-non-6-ene- 3-one is prepared by reacting 1-bromo-2-methylbut-1-ene with lithium, the product being reacted with ethyl vinylketone in the presence of cuprous chloride, bromide, or iodide. Tert.-butyl diethylphosphonoacetate is obtained by reacting triethyl phosphite with tert.- butyl bromoacetate. Triphenyl 4 - methyl - 5 - carboxy - pent - 4- enyl phosphonium halide is prepared by reacting a 5-halo-pentan-2-one with an alkyl dialkylphosphonate of formula in which R 1  represents a methyl or ethyl radical and R 2  represents a methyl, ethyl or tert.-butyl radical) in the presence of a strong base to obtain alkyl 3-methyl 6-halo-hex-2-enoate which is hydrolysed to the acid and reacted with triphenyl phosphine to form the phosphonium halide. The preparation of the bromide is described. Reference has been directed by the Comptroller to Specification 1,209,903.

Title: Improvements in or relating to a starting up device for diesel engines or the like
IPC: F02P19/02
Filed: 1969-10-29
Abstract: 1293364 Systems for starting prime movers AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 29 Oct 1969 [5 Nov 1968 8 Oct 1969] 52927/69 Heading H2H A system for starting a diesel engine includes an engine heating circuit which is energized by a manual switch. At the same time, a thermal delay device is actuated, and this closes a switch to the starter supply circuit after a time dependent on the ambient temperature. In the embodiment shown in Fig. 1, each cylinder of the engine is heated by a heater plug 10, and the delay device consists of a resistor 7 which heats a bimetal contact 11. To start the engine, an anti-theft switch 1 is first closed, resulting in the closure of a contact 3 in series with a starting switch 4. Contacts 5 of this switch are now closed, and current is supplied to the resistor 7 and heaters 10. After a delay, the contact 11 closes, energizing a coil 13 which simultaneously makes a contact 15 to supply the starter 16, and moves a switch 9 over to a contact 14 which removes current from the resistor 7 and enables the heaters 10 to be supplied direct from the battery B. The removal of the resistor 7 from its previous connection in series with the heaters 10 compensates the latter for the voltage drop due to the connection of the starter 16. As the bimetal 11 cools, its contact will open, and if the engine has not started, the switch 5 is held closed and a further heating cycle takes place. If the engine is already warm, a contact 6 of the switch 4 can be closed, thus energising the starter immediately indicator lamps 18, 19 may be included in the circuit. Further embodiments are described with reference to Figs. 2-6 (not shown). The bimetal 11 may be shunted or replaced by a thermocontact responsive to engine temperature, or by a thermistor. The system may also include a switch operable to open and close a fuel conduit during starting and stopping of the engine respectively.

Abstract: 1,160,747. Radioactive borehole logging. BRITISH PETROLEUM CO. Ltd. Dec. 15, 1966 [Dec. 16, 1965], No.53452/65. Heading G1A. A borehole logger comprises a sonde containing a gamma-ray detector, a multi-channel pulse height analyzer and means for transmitting the channel contents to the surface by time division multi-plexed position modulated pulses, and means at the surface monitoring the contents of selected combinations of the channels to provide a display of the energy spectrum of the gamma-rays detected. Pulses produced in a scintillation detector D due to gamma-rays from natural or induced radioactive isotopes in the formations surrounding the borehole are separated by a pulse light analyzer PD into 23 channels. The pulses are standardized by mono-stable circuits M1-M23 and integrated by integrators I1-I23 to produce signals representative of the number of pulses received in each channel. The outputs of integrators I1-I23 are fed in turn through sequentially operated AND gates A1-A23 to a multi-plex transmitter TT. In TT the analogue signals from the integrators are converted into pulse position modulated signals by an integrator and threshold device and transmitted up the logging cable to a multi-plex receiver TR which distributes the position modulated pulses through 23 AND gates B1-B23, to stores ST1-ST23. The contents of the stores may be displayed on a C.R.T. in the form of the spectral distribution of gamma-rays received by the detector, and the contents of selected combinations of stores may be displayed on indicators IND1-IND5 by suitable closure of switches SS1-SS115. The signals from the units TT and TR for opening the gates A1-A23 and B1-B23 are provided by a twelve cathode discharge tube, each cathode of which is connected to two gates selectively operable by a bi-stable circuit controlled from the final cathode of the tube, Fig.2 (not shown).
