Title: Method and apparatus for casting battery connector straps
Inventor: TIEGEL RALPH GEORGE
IPC: H01M50/541
Filed: 1966-11-24
Abstract: 1,136,009. Casting composite battery-plate connectors. TIEGEL MFG. CO. 24 Nov., 1966, No. 52752/66. Heading B3F. [Also in Division H1] Moulds 14 are plunged into a reservoir of molten lead (21) to fill them and heat them before connector lugs 13 of battery plates (12) are dipped into them and retained there until the connector straps 18 and terminal posts 17, forming in the moulds, weld to the lugs 13; the moulds 14 and their contents are then chilled by coolant such as water or oil passed through passages 47, 48. The relative movements of battery plates (12), moulds 14 and reservoir (19), Fig. 2 (not shown), may be achieved by vertical reciprocation of the moulds; or the moulds could be stationary while the plates and reservoir are moved. The duration of the coolant flow is controlled by a timing device and, when it is finished, air is used to blow coolant out of the passages 47, 48. Before introduction to the moulds 14, the lugs 13 are contacted by a sponge, Fig. 3A (not shown), impregnated with flux. The steel or berylliumcopper mould 14 has a notch 44 through which molten lead flows into the mould when it is almost completely immersed and out through which excess lead and dross flows when the lugs 13 are introduced.

Title: Process for producing carbon fibres from mesophase pitch
IPC: D01F9/145
Filed: 1974-12-10
Abstract: 1496677 Production of carbon fibres UNION CARBIDE CORP 10 Dec 1974 [11 Dec 1973] 53246/74 Heading C1A [Also in Division C5] High modulus, high strength carbon fibres are prepared by spinning carbonaceous fibres from a non-thixotropic carbonaceous mesophase pitch the pitch having a mesophase content of from 50 to 65% by wt., wherein less than 50% of the molecules in the mesophase have a molecular weight greater than 4000 while those molecules with M.Wt. of 4000 or less have a number average M.Wt. of from 1400 to 2800, and wherein molecules in the non- mesophase portion of the pitch of a number average M.Wt. of from 800 to 1200 and less than 20% of the molecules in the non-mesophase portion having a M.Wt. of less than 600, the carbonaceous fibre being thermoset by heating in an O 2 - containing atmosphere to render it infusible, and then carbonizing the thermoset fibre by heating it in an inert atmosphere. Suitable mesophase pitches having the improved rheological and spinning characteristics are prepared by heating a carbonaceous pitch in an inert atmosphere at 380 to 440 C. while agitating (e.g. by stirring or rotation of the pitch) the pitch during the formation of the mesophase to produce a homogeneous emulsion of the immiscible mesophase and non-mesophase portions. Alternatively, the pitch may be subjected to reduced pressure (i.e. less than 100 mm. Hg) or by passing an inert gas through the pitch during formation of the mesophase, the gas (e.g. N 2 Ar, Xe, He or steam) being passed at a rate of at least 0À5 scfh per pound of pitch while agitating the pitch. The fibres may be thermoset in air at from 250 to 400 C. (e.g. for 5 to 60 mins at from 275 to 350 C.). Carbonization in an inert atmosphere such as those listed above may be effected by heating to a temperature greater than 1000 C. for 0À5 to 25 min. It is preferred to heat the fibres at 700 to 900 C. for 30 sec. to 5 mins. prior to the carbonization step. The carbonized fibres may be further heat treated at from 2500 to 3300 C. in an inert atmosphere (e.g. as those above) of 10 sec. to 5 mins.

Title: Apparatus for variably weighting received echoes in a moving target indicator radar
IPC: G01S13/528
Filed: 1969-11-05
Abstract: 1291239 Pulse radar WESTINGHOUSE ELECTRIC CORP 5 Nov 1969 [18 Nov 1968] 54260/69 Heading H4D An MTI system comprises means for generating radar transmissions at variable time intervals, means for extracting one or both of the in-pulse or quadrature components of the echo signals with respect to a reference signal, means for sampling the components and coding into a digital word, means for storing a sequence of said words, means for applying weighting coefficients to the sequence and to the most recent received word, the coefficients being dependent on the intervals between all the transmitter pulses corresponding to the words being considered, means for summing the weighted words and means for converting the sum to an analogue video signal. Video signals are produced by phase comparison of IF echo signals with a reference oscillator 2 phase locked to the transmitter 4. In phase and quadrature video signals are produced by detectors 12, 14 and multiplexed into A-D converter 16 by switch 18. The converter samples the analogue signal every 2.7 ÁS and produces an eight bit digital representation of the sample amplitude which is read into register 30. At the same time the words already in registers 30, 32, 34 are shifted by one place. The four pulse canceller 6 then forms the sum aA-bB+cC+ dD where a, b, c, d are the weighted coefficients and A, B, C, D are the echo amplitudes, A being the oldest echo. The coefficients are functions of the time intervals T 1 , T 2 , T 3  between pulses A-B, B-C, C-D respectively. Since the coefficients are dependent of the interpulse periods which vary there is stored in memory 19 a number of sets of coefficients, e.g. for a four pulse variable period there will be four sets of coefficients. The sums of the weighted pulses are read into two registers 80, 82 and then into D-A converters 84, 86 to the MTI video output via peak detector 88. The timing of canceller 6 is controlled from unit 22 which also controls the memory 19 and range counter 28. The radar working range is determined by the counter which counts a 185 KHz clock and operates the memory 19 between predetermined minimum and maximum ranges. A sequence control 24 determines the interpulse periods and provides trigger pulses to the transmitter 4. The cancelled sum is produced in canceller 6 by a high speed adder whose inputs are connected to gates providing the echo words directly or shifted in order to multiply or divide, the required coefficient being. produced by a combination thereof which is decided by a master control (Fig. 4, not shown). The use of such weighted coefficients produces a velocity response with a wider clutter notch than with constant weighting (Fig. 1, not shown) but retains the sensitivity to the normally "blind" velocities of conventional MTI systems.

Abstract: 1376337 Electro-photographic copier PITNEY-BOWES Inc 24 Nov 1971 [9 Dec 1970] 54657/71 Heading G2A Reciprocation of an original-bearing carriage 12 between home and transfer stations, with illumination at a stationary station during the home return stroke (to the right as shown), is effected by means of a reciprocatory endless chain 94 having a pin 116 co-operating with slotted member 118b and bifurcated member 120a, depending from the carriage, to provide a lost motion coupling at the end of each stroke and with switch-actuating sensing members 140 and 140a at the end of each stroke to reverse the direction of movement of chain 94 or terminate the movement at the home station. Carriage drive chain 94 is driven by a copy drive chain 52 through a transmission 82 (and intermediate chain 86) having forward, reverse and neutral positons and operated by solenoids 186 and 182 energized on sensing of means 140 and 140a. The carriage is driven through the forward stroke at a faster rate than through the return stroke. Simultaneous engagement of forward and reverse gears is mechanically and electrically prevented. During the forward stroke, a tab 190 depending from the carriage triggers a feed switch 64 to operate the copy feed rollers 28 and, after a delay by means of timing device 60, the illumination lamp and charger. During the return stroke, an arm 210 (adjustable for length of copy sheet desired) depending from the carriage triggers a knife switch 66 to terminate operation of copy feed rollers 28 and cut the copy material.

Abstract: 1,158,998. Ammonium sulphate. STAMICARBON N.V. 8 Dec., 1966 [9 Dec., 1965], No. 55097/66. Heading C1A. In a process of preparing caprolactam from cyclohexanone oxime in a sulphuric acid medium the crude product is neutralized with ammonia and the crude lactam oil, which separates as an oil-phase, is extracted with an organic solvent, e.g. benzene, to leave an aqueous ammonium sulphate solution containing more than 25%, based on the weight of the sulphate, of organic components which are soluble at room temperature; ammonium sulphate is recovered from this solution by evaporating sufficient water to form an organic phase and an aqueous phase, removing this organic phase and crystallizing ammonium sulphate from the remaining aqueous phase. Ammonium sulphate may also be crystallized from the aqueous phase from which the crude lactam oil separates.
