Abstract: 1443343 Flame drilling TSENTRAL GEOFIZICHE TREST 15 Nov 1973 [7 June 1973] 53136/73 Heading E1F For the boring of a hole in the ground by a gas jet discharged from a nozzle of a non-anchored rocket, the rocket is so designed that firstly a balance can be achieved, at a given stand off distance between the nozzle and the face of hole, between the reaction force of the jet and the counter pressure arising from the face and the oppositely directed forces urging the rocket towards the face so that variation from this stand off distance as the face is burnt away causes appropriate movement of the rocket with respect to the face to maintain the stand off distance and secondly the velocity of the waste gases of the jet will exceed the velocity at which maximum sized particles of rock broken off from the face will become weightless when entrained in the gases. Preferably the stand off distance is greater than four times the diameter of the nozzle and there is created between the rocket and the wall of the hole a radial gap of about half the diameter of the rocket. Appropriately directed auxiliary gas jets can be used to create the required balance of the rocket when the reaction force and counter pressure cannot be balanced by the oppositely directed forces for a desired stand off distance.

Title: Time-bandwidth reduction system
IPC: H04N1/413

Abstract: 1,090,098. Data transmission system; pictorial communication. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Dec. 23, 1965 [Dec. 28, 1964], No. 54584/65. Headings H4F and H4P. In a system for transmitting a binary coded pulse train, bandwidth requirements are reduced by transmitting a single signal in place of each successive group of n bits, the single signal representing the associated group of n bits by either its amplitude, its frequency or its phase. As described a binary pulse train derived by scanning a printed or typewritten document is divided into groups of two or three bits, and each group is transmitted by a single signal significant by either its amplitude (Figs. 3, 5, 9, 16), its frequency (Figs. 18, 20) or its phase, to control a remote display tube. In a first embodiment a binary pulse train 40, Fig. 3, is fed into a two-stage shift register (described in detail in Fig. 4, not shown), and successive pairs of bits are sampled 70, 72, 66, 67, 68, 69, so as to energize one of four leads 51, 61, 71, 81, which in turn cause a pulse of amplitude level 1 (taken to be zero) level 2, level 3 a level 4 to be transmitted. Video sync pulses are also transmitted. At the receiver a threshold circuit 110 Fig. 5 (described in detail in Fig. 6, not shown) opens one of four gates 132, 133, 134, 138 in accordance with the amplitude of the pulse received. One of these gates is thus able to pass a strobe pulse 146, which causes an appropriate pair of clock-pulses from a generator 139, which is triggered by each incoming data pulse, to be applied to a display tube. In a second embodiment (Fig. 15, not shown) groups of three bits are transmitted by 8-level pulses. In a third embodiment the amplitude significant pulses are replaced by bursts of frequency significant A.C. This can be achieved either by using a voltage-controlled oscillator and appropriate demodulator in association with the first embodiment described above, or by the use of four oscillators at the transmitter (Fig. 18, not shown) and four band-pass filters (Fig. 19, not shown) at the receiver. The Specification also mentions that phase modulation could be used.

Abstract: 1319100 Battery terminals GENERAL MOTORS CORP 19 Nov 1970 [24 Nov 1969] 55055/70 Heading H1B [Also in Division B3] In a method of making a terminal of a lead acid storage battery, a temporary carrier member 26 is formed by casting lead or lead alloy in a cavity 20 of a mould 18 into which is placed a core 12 having a threaded aperture 14 designed to receive a complementary cable connector. The composite comprising the carrier 26 and core 12, which may be of stainless steel, is then placed in a second mould 28, Fig. 4, in which lead is cast to form a bushing 36, Fig. 5. Adhesion between the parts 26 and 36 is prevented by ageing the carrier 26 to form an oxide film. The bushing 36 is then moulded into a wall 38 or a cover of a battery case, the active plates are positioned within the case, and a lug 41 of a plate strap 40 is fused to the bushing 36. The battery plates are then electrochemically formed by current supplied through a clip 44 which has been attached to the carrier 26. When manufacture is complete, the carrier 26 is removed to expose the bore 14 for the cable connector. In an alternative embodiment specially adapted for thin-wall battery cases, the rear end of a modified bushing (56, Fig. 7, not shown) is passed through two apertures in the case wall and plate strap lug (58) respectively. The end of the bushing (56) is then riveted to the lug (58) and the riveted joint is fused with a torch.

Abstract: 1,185,556. Digital transmission systems; automatic phase lock systems. INTERNATIONAL BUSINESS MACHINE CORP. 7 Dec., 1967 [8 Dec., 1966], No. 55706/67. Headings H3A and H4P. The frequency of an oscillator in a digital data receiver is controlled by transitions through a preset voltage level in the data and also by transitions in the differentiated data. As described the inupt data is multilevel as generated by the transmitter of Specification 1,154,648, the received signals comprising pairs of significant digits separated by pairs of non-significant digits, the digits being at rate d. The data is preceded by a synchronizing signal 1010 at rate d/2. The received signal is fed at M to a first channel comprising delay RET and to a second comprising differentiator DIF. The channels feed gates 1-4 and inverters I to switch triggers T3, T4 by positive-going transitions. The triggers' outputs control the frequency of an oscillator OsP via gates 5, 7, 8 and filter Fi. The output M1 of the first channel also controls the oscillator, via gates 6, 8 and Fi. The oscillator produces clock trains P, Q, Fig. 3, 90 degrees apart, P being fed to divider triggers T1, T2. Gates 9, 10 are so connected to P and the outputs of T1, T2 that they output clock signals 9<SP>1</SP>, 10<SP>1</SP>, as shown, 180 degrees apart, the signals gating triggers T3, T4 which are also fed by Q so that the triggers will output pulses (T3, T4, Fig. 3) which have a width dependent on the state of synchronization of the oscillator with the received input signals. The signal M1 also passes to a shift register R1-R4, whose second stage R2 outputs the binary data R<SP>1</SP>2 represented by the received input signals. The signal M1 is gated to stage R1 by pulses 15<SP>1</SP> derived from pulses Q via gate 15 so that R1 is switched by the bits of the significant bit pairs. The output of R1 (R<SP>1</SP>1) switches R2 when gated by the output of T1 so that R2 outputs data at bit rate d/2. The data is also gated by R<SP>1</SP>3, R<SP>1</SP>4 to stages R3, R4. During the sync. signal 1010 ... trigger SL prevents the differentiated signal M2 from reaching the oscillator, so synchronization takes place on M1 only. When sync. is attained both Ml and M2 control the oscillator, as described above. Because transition in the differentiated signal M2 tends to occur late if it is the next transition to occur after a transition in the signal M1, such a transition in M2 is prevented from affecting the oscillator. Thus, if stages R3, R4 contain different bits a signal X<SP>1</SP> appears at gate 19 which blocks gate 1 in the output M2. If the data applied to the transmitter input is at half the oscillator frequency and is then converted to the form in which each bit is inverted for half its duration, the resultant signals being transmitted as described in Specification 1,154,648, the receiver is modified as shown in broken line.
