Title: Impulse correlation function generator
IPC: G01S13/10
Filed: 1964-08-04
Abstract: 1,073,024. Correlation techniques. STANDARD TELEPHONES & CABLES Ltd. Aug.4, 1964 [July 24, 1963], No.30885/64. Heading G1U. [Also in Division H4] In a pulse radar (Fig. 1) a relatively long pulse coded signal S1 is formed from a sub-pulse and transmitted, a pulse coded signal S2 is formed, delayed relative to signal S1, and signals S1 and S2 are fed to a correlation circuit (2) together with the echo signal S3; in the correlation circuit signals S1 and S2 are simultaneously and variably delayed (12) and thereafter fed to individual multipliers (10, 10') each fed also with echo signal S3, the multiplier outputs are integrated (11, 11') and the integrator outputs are multiplied in a further multiplier (15) and thereafter integrated (16) to form the final output signal. The code for signal S2 is made such that the final output signal is a single "spike" without time side-lobes and is much shorter than the transmitted signal. As the variable delay (12) is increased in steps corresponding to multiples of the sub-pulse duration the final output signal is zero at all instants other than that in which the variable delay is indicative of target range. The codes utilized for signals S1, S2 may be steps of positive, zero and negative amplitudes (Figs. 2, 3, 4) or may be amplitude steps of sub-pulses of 0‹ and 180‹ relative phase of a reference oscillator (Fig. 5).

Title: Improvements in or relating to a method of producing steam by utilizing waste-heat
IPC: F22B1/18
Filed: 1956-10-11
Abstract: <PICT:0806017/III/1> The waste heat from a reaction generating a gas at about 300 DEG  to 400 DEG  C. is utilized by causing the gas to heat water under a pressure of several atmospheres, which pressure is then relieved by a valve whereby steam is generated; the steam being used to pre-heat and saturate a gaseous component of the main reaction. In a suitable apparatus, the gases from a reactor 1 in which natural gas is reacted with steam to generate hydrogen and carbon monoxide, pass through a tube 2 and heat water pumped through a tube 3 which is under 10 atmospheres pressure.  The pressure on the heated water is relieved through a valve 5 and the resulting steam passes at atmospheric pressure downwards in a saturator 6, in counter-current with a gas, e.g. natural gas entering at the base. The gas, heated and saturated with steam, passes to the reactor 1. The condensed water in the saturator 6 is recirculated by a pump 8.

Title: Coin-freed vehicle-parking timers
IPC: G07F17/24
Filed: 1936-11-17
Abstract: 485,201. Time-alarm signals. MICHAELS, F. L. Nov. 17, 1936, No. 31505. Convention date, May 12. [Class 118 (ii)] [Also in Group XVIII] In a vehicle parking time meter, a time indicating pointer 83 is displaced from a zero position by manual rotation of a shaft 22 after insertion of a coin, and is slowly returned by a spring 73 under the control of an escapement 100. As shown, two such pointers 83 are visible through front and rear windows 50, and are carried by a segment 77, loose on shaft 22 and fast with a toothed segment 74 geared to the escapement. The shaft 22 drives the segment 77 to displace the pointers 83 by means of a pawl 97 which engages one or other of two pins spaced around the periphery of the segment. This enables an extended period to be prepaid initially, the pawl engaging each pin in turn upon successive rotations of the shaft 22. The pins can be set in alternative holes in the segment to vary the extent of the initial and extended periods, and the pawl 97 is adjustable on shaft 22 to allow fine adjustment to be made. Flags 49 for indicating expiration of the prepaid period normally obstruct the pointers 83, but are lowered from view against the action of a spring when shaft 22 is rotated and held by a latch engageable with their operating mechanism. At the expiration of the period, an abutment 75 on segment 74 trips the latch so that the flags rise into view to attract the attendant's attention.

Title: Improvements in and relating to article delivery apparatus
Inventor: ZOLLMANN PETER MARTIN
IPC: H01J9/46
Filed: 1968-07-02
Abstract: 1,254,293. Feeding lamp filaments from conveyer belts. BADALEX Ltd. 8 Aug., 1969 [2 July, 1968], No. 31554/68. Heading B8A. An article delivery apparatus having a conveyer 2 movable regularly between a supply station A and a delivery station B, a plurality of carriers 9 engaged by the conveyer and movable relative thereto, a carrier loading control element 19, at the supply station operable to hold a carrier 9 at that station until loaded, and a carrier delivery control element 18 to receive carriers 9 released by the loading control element 19 and moved therefrom by the conveyer 2 and to present carriers 9 at predetermined intervals to the delivery station B the conveyer 2 being operable at a speed greater than that corresponding to the rate of presentation of the carriers 9 to the delivery station B. As shown, applied to the feeding of filaments to a mount mill 8, the carrier loading control element comprises a pair of sprockets 19 the teeth of which are engageable by the carriers, the sprockets being indexable in response to loading of an article. The carrier delivery control element comprises a pair of delivery sprockets 18 the teeth of which are engageable by carriers delivered thereto by the conveyer, the sprockets 18 being indexable according to a predetermined timing. The latter is synchronized with the drive of a pick-up member 20 associated with the mount mill 8. The sprockets 19 are stepped forward in response to a signal generator by photo-electric means when a filament appears at the station A. The same signal causes an air jet to blow the filament through an opening 4 on to a carrier 9. As the sprockets 19 are stepped onwards, the filaments are successively engaged by the conveyer 2. The latter comprises an endless belt which is driven continuously by a drive wheel 7 mounted concentrically with the sprockets 18, 18. The filaments are fed to the station A by the action of a vibratory table 1 on to which they are thrown in random disposition. Some pass down an aperture 35 and are displaced by an air jet 37 (Fig. 4) along passages 36, 38 being untangled in the process. As they then pass an air jet 28, the latter tends to eject a tangled pair of filaments since they extend above a given height. As a photoelectric device is passed at 25 an air nozzle is operated at 27 to eject a filament which might be immediately behind the filament at 25. A similar action occurs at 29 and the filament then reaches the light source which activates the air jet at the station A.

Title: Trainable system of cascaded processors
IPC: G06N20/00
Filed: 1971-07-06
Abstract: 1353936 Trainable processing systems TEXAS INSTRUMENTS Inc 6 July 1971 [6 July 1970] 31619/71 Heading G4R A trainable system comprises a number of non-linear trainable processors connected in cascade. The processors are trained in turn, the three inputs to a processor being trained being a sequence of signals I derived from a system input signal U(t), the output X of the preceding processor, now operating in execution mode, and a desired response signal Z corresponding to the class to which U(t) belongs. The input signal U(t) may be digital or may be an analogue signal, e.g. a speech signal. In the latter case the signal is sampled and normalized and used to provide k sequences I each consisting of m signals, there being k cascaded processors, Fig. 1. A signal sequence Xo is also derived from the signal U(t). Processor 1 is trained first, receiving as inputs sequences Xo, Io and desired response sequence Z. The processor includes a tree storage system which is set up by the training signals to define paths through the tree. Each successive pair of signals (I, X) in the training sequence Io, Xo defines a node in the tree, and either accesses that node location in the store or in the absence of such a location sets up a new node location (e.g. as in Figs. 7-11, not shown). Registers associated with the node location store the number of times that that node has been associated with each particular response Z. Thus a particular node may have been associated with a desired response Z1 twice and a response Z2 once during the training sequence. Processor 1 is now operated in execution mode (inputs Io, Xo only) to generate a signal X1 which is the processor's best estimate of the desired response to a second system input U(t). In response to this second input U(t) a signal I1 is generated and used, together with X1 from processor 1 and the desired response Z to U(t), to train processor 2. Training of processor 3 now takes place, trained processors 1 and 2 operating in execution mode and the system input signal being a third signal U(t), and so forth until processor k has been trained. When the trained system is operating in execution mode an input signal U(t) is applied and signals Xo, Io-I k-1  are generated. These signals are applied as shown to the processors 1-k, each signal of the sequence Xn applied to  the (n + 1)th processor being a function of the number of times the various desired values Z1, Z2, ... have been associated with the node defined by the corresponding (I, X) signal applied to the nth processor. Processor k provides an output Xk which is the best estimate of the desired response to U(t). In one embodiment the signals Io-I k-1  are so related that the signal sequence In applied to the nth processor is the signal I k-1  applied to the kth processor delayed by k-n time units, a time unit being the mth part of the duration of a sequence I.
