Title: Improvements in or relating to the manufacture of safety fuses for mining or blasting
IPC: C06C5/08
Filed: 1927-04-06
Abstract: 293,479. Fritzsche, J. April 6, 1927. Blasting fuzes having a core of powdered or granulated material are dried during their manufacture, after the spinning operation and prior to impregnation, by means of hot air &c. In making the powder core, the mixture may be wetted or moistened with any suitable liquid to minimize danger, and to facilitate proper filling of the wrapping by the powder. This moisture is then expelled after the fuze leaves the last winding unit by passing the fuze through any suitable drying apparatus, after which it may be coiled on a drum, for subsequent impregnation. To prevent any soluble constituent of the powder from being carried out to the surrounding covering, the core may be wrapped with sized paper or the like, through which permeation of a liquid cannot readily occur.

Abstract: 1,117,145. Analogue calculators. INDUSTRIAL NUCLEONICS CORPORATION. 15 June, 1965 [19 June, 1964], No. 9532/68. Divided out of 1,117,142. Heading G4G. In apparatus for computing the values of spectral power-variance in a measured characteristic, e.g. thickness a travelling-material, the output 60 of a gauge responsive to the measured characteristic is applied alternately to a moving recording medium 210, 210a under control of a programmer 202, recording on one medium taking place at a low speed while the other medium is played back at a high speed, and the frequency - transposed signals are applied through filtering means to a statistical variance computer which may be as described in Specification 1,117,144. Separate filters 242, 244, 246 and computers 248, 250, 252 may be provided for deriving the long-term, short term and cross-sheet variances, and a further computer 254 may be used to derive the total variance. The apparatus is suitable for determining statistical variances when the output of the gauge occupies a frequency range which is too low for normal electrical filters to be used directly.

Title: Improvements in or relating to the production of injection mortar or porous concrete
Inventor: WINKLER FRITZ A SCHENKER
IPC: C04B22/14

Abstract: 1,205,664. Porous mortar and concrete. F. A. SCHENKER WINKLER, and R. B. SCHENKER. 28 Feb., 1968 [3 March, 1967], No. 9556/68. Heading C1H. Porous concrete and injection mortar are made from a mix containing Portland cement and, based on the weight of the cement, 0À01- 0.6% of a nitrogen releasing compound having a nitrogen-nitrogen bond and 0.01 to 0À5% of an activator to decompose the nitrogen compound with release of gaseous nitrogen. Suitable nitrogen releasing compounds are (a) azo compounds, such as p-nitrobenzene diazonium salt of naphthalene disulphonic acid and salts of diazotized nitroaniline, which are decomposed by reducing agents such as iron-II-gluconate and (b) hydrazine compounds, such as benzenesulphohydrazide, hydrazine sulphate, dihydrazine sulphate, and diphenylsulphon-3,3<SP>1</SP>- disulphohydrazide, which are decomposed by an oxidizing agent such as potassium copper tellurate, potassium persulphate, lead peroxide, sodium perborate and a mixture of copper sulphate and sodium aluminate. Lignin sulphonates, protein decomposition products, hydroxy- or polyhydroxy-carboxylic acids and their derivatives can be added in amounts of 0.01 to 0.4 wt. per cent (based upon the cement) as plasticizers. The mix can also contain stone powder, quartz powder, bentonite, infusorial earth or chalk as a filler and methyl cellulose as a water retaining agent.

Abstract: 1,207,106. Pneumatic separators. METALLGESELLSCHAFT A.G. 21 Feb., 1969 [30 March, 1968], No. 9577/69. Heading B2H. Blast furnace sinter is fed on to a porous bottomed rotary cooler 1 in the form of a layer. Air is blown by a blower 4 up through the porous bottom of the cooler to remove fines from the sinter and carry them into a hood 5. The fines are transported by a conduit 6 to a separator 8 where they are collected and then returned to the sintering apparatus. A fan 7 draws the air through the separator 8. The air pressure required to effect separation is dependant upon the thickness of the sinter layer on the cooler, ranging from 100 to 180 mm H 2 O for 0.5m thickness sinter to 400 to 700 mm H 2 O for 1.4m thickness sinter.

Filed: 1955-04-01
Abstract: 771,464. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. April 1, 1955, No. 9603/55. Class 40 (4). Dialled digits are recorded in code on a magnetic drum which is driven only while each digit is being received, the drum being subsequently driven continuously to recover the digits for ticketing purposes. Line relay R110 operates over the calling loop followed by hold relay R120. Dialled digits are repeated over contacts 113, 125 to set up the connection in known manner. The first impulse of a digit energizes change-over relay R130 so that the digit advances wipers 153-156 step-by-step. R130 also energizes timing relay R140. At the end of the digit R130 falls back slowly to energize motor 201 and to apply a lowfrequency signal over wipers 153-156 to one or more recording heads 210-213, the L.F. signal being superimposed on a H.F. bias voltage supplied through capacitors 221-224. The L.F. signal is thus impressed upon that part of the magnetic drum passing the selected recording heads. A predetermined time after R130 falls back the timing relay R140 also falls back to cut off the L.F. signal and the circuit to the motor which stops the drum after providing a short spacing. R140 also completes a homing circuit for wipers 153-156. Succeeding digits are recorded in like manner. Recovering information. When the calling subscriber hangs up line relay R110 and hold relay R120 restore to re-energize the motor over contacts 124 and off-normal contacts 202. Pick-up heads 214-217 impress the.recorded signals on the grids of related tubes 225-228, so operating related relays R260-R290 according to the registered digit to mark the appropriate conductor 1-0 for use in toll ticketing apparatus. The record is erased by erase head 219. The prior state of the art is represented by a reference to Specification 317,817, [Class 40 (iv)].

Title: Improvements in or relating to methods of manufacturing aluminium nitride
IPC: C01B21/072
Filed: 1966-03-07
Abstract: Aluminium nitride is manufactured by contacting gaseous ammonia and a solid mass of an aluminium-zinc alloy, at a temperature between 900 DEG  C. and 1200 DEG  C.  The preferred alloy has a zinc content between 5% and 20%.  According to an example, a bar of the alloy was heated in a corundum crucible in a furnace in a current of ammonia at 780 toors, and when the strongly exothermal reaction began the ammonia current was strengthened.  The product was cooled in an ammonia current.  It is stated that magnesium-aluminium and lithium-aluminium alloys have been used but lead to an impure product.

During normal horizontal flight the shutters 15 and 5 remain closed with the shutters 1 and 19 open. To achieve a vertical take-off the valves 1 and 5 are operated so that they are respectively closed and open to direct the gases through branch 12. When the valve 5 is opened the gyroscope and servomotor are connected automatically to the cables 21 and 22, which to maintain the aircraft substantially level at a particular altitude, can open or close the shutters 15 and 19 in the appropriate sense. When the aircraft is taking off the cables 21 and 22 may be connected to the pilot's control member.

Title: Hybrid data communications system
Inventor: CLARK ALAN
IPC: H04L12/40
Filed: 1996-08-01
Abstract: A hybrid data communication system comprises synchronous line cards (3) and asynchronous line cards (2) connected to a common data bus (1). The common data bus (1) includes a contention bus (7) arranged to communicate contention signals between the line cards (2, 3). The synchronous line cards are arranged to transmit a high priority contention signal to suspend any ongoing transmission by an asynchronous card (3) and to gain access to the bus (1) for the immediate transmission via the bus (1) of synchronous data. The contention bus includes an acknowledgement line (ACK) which is driven low by a receiving line card to indicate that it is receiving data. The receiving line card performs error checking and only releases the acknowledgement line when the received data is determined to be error free. In a preferred example the asynchronous line cards (2) are arranged to monitor the contention line (7) to detect the initiation of a contention cycle by a synchronous line card (3). Subsequently on the completion of the contention cycle the asynchronous cards (2) interrupt any ongoing transmission of a data frame to allow the transmission of data by the synchronous card (3).
