Title: Improvements in or relating to aerials
Inventor: RADFORD MATTHEW FREDERICK
IPC: H01Q11/10
Filed: 1961-11-03
Abstract: 965,802. Aerials. MARCONI CO. Ltd. May 15, 1962 [Nov. 3, 1961], No. 39424/61. Heading H4A. The invention relates to wideband aerials similar to known logarithmically periodic aerial arrays such as disclosed in Specification 884,889, but in which the taper ratio, that is the ratio of the length and spacing of adjacent elements, is not a constant thus allowing the gain of the array to be greatest at the frequency where this is required. For example, in television reception band III usually requires more gain than band I, thus the taper ratio is preferably greatest at the higher frequency end of the frequency band. One embodiment, Fig. 1, comprises an array of dipoles connected to a two-wire feeder F1, F2 fed at one end, the taper ratio decreasing from a value of approximately 0.95 at the higher frequency (feed) end to a value of approximately 0.8 at the lower frequency end and the dipole spacing varying from approximately #/6 at the higher frequency end to approximately #/8 at the lower frequency end. Fig. 2 shows an array of folded unipoles connected to a single feeder and supported by a guy W from a mast M to hang as a catenary. Fig. 3 shows an array of parallel horizontal dipoles D hung on a feeder F between two masts to also form a catenary, the effective height, in wavelengths, of the higher frequency dipoles being greater than that of the lower frequency dipoles, thereby reducing the elevation of the main beam. Fig. 4 shows a twin zig-zag array each zig-zag Z consisting of coplanar parallel lengths of conductor at right angles to the back bone wire F and joined in series by longitudinal lengths of conductor, the two backbone wires forming a flared twin-wire feeder.
Patent GB-394690-A (GB)
Abstract: 394,690. Calculating-apparatus. EGGERS, F. G. H., 41, Keston Road, and SCHœTT, F. J., 43, Keston Road, Thornton Heath, Surrey. Dec. 31, 1931, No. 36084. [Class 106 (i).] In a machine for keeping accounts and comprising account-storing devices constituted by denominational columns of racks 'as described in Specifications 364,612, 364,639, and 377,988, the storing devices are arranged in compact form for easy assembly and designed to obtain a mechanism of light construction. As shown in Figs. 2 and 6, the connected racks 134 forming an account set instead of being supported by plates as described in Specification 377,998 are supported at the rear in the teeth 2 of comb plates 1 arranged in sections that are connected by tongues 8, 9, passing through slots in supporting plates 5 spaced by tubes 6 surrounding the posts carried by the end frames of the framework. By the use of the plates 5 between every twenty account sets undue sagging of the racks is prevented. The free ends of the sets of racks are supported between the bars forming the usual draw-bars 200. Each draw-bar has a latch 209 co-operating with the known form of segregating mechanism, and is formed with an abutment 209a normally engaging a part 187a to prevent movement of all draw-bars except that selected by the vernier bars 220, 221 on the withdrawal of the usual clearing-bar 211b.

Patent GB-1437025-A (GB)
Title: Method and device for determining the state of charge of galvanic energy sources
IPC: H01M10/48
Filed: 1973-08-23
Abstract: 1437025 Measuring battery parameters DEUTSCHE AUTOMOBIL GmbH 23 Aug 1973 [30 Aug 1972 9 March 1973] 40059/73 Heading G1U [Also in Division H2] A method of measuring the state of charge of a battery involves integrating the charge and discharge currents after they have been weighted to take account of temperature, gassing and the charging response of the battery. A current transformer 7 provides positive and negative voltages representing charge and discharge currents respectively if charging, feedback Dl, R6 operates at inverting amplifier 9 to multiply the voltage by a fixed factor. If discharging, feedback D2, R7 operates. R7 has a negative temperature coefficient reflecting the loss of discharge capacity at low temperatures. The discharge current at terminal 10 is fed to a parallel combination of a fixed resistor R9 and a voltage dependent resistor R8 which raises the input voltage to a power 1 + m where m depends on the type of battery and is of the order À15-À33. The arrangement registers the increased loss of discharge capacity at high discharge current. The charging current voltage from terminal 14 is combined with the discharge current voltage at the input of amplifier 12 whose output represents the difference between the two inputs and which is integrated by meter 13 which may include an alarm to indicate a low level of discharge capacity. In order to register the effect on the charging efficiency when gas begins to be evolved from the battery electrolyte, a potentiometer network R3, R4 provides a voltage which represents the "gassing voltage" (at which gassing begins). Since this voltage is temperature dependent R4 has a negative temperature coefficient. Amplifier 4 compares the gassing voltage UGAS and the battery voltage UB, turning on transistor 11 as the UGAS is exceeded, thereby shunting an increasing portion of the charging current fed to the amplifier 12. In a second embodiment Fig. 2 (not shown) the signal representing U B -U GAS  is further processed by an amplifier (22) with capacitive feedback (C2) to provide a signal representing an ideal charging current. This is compared to the actual charging current to provide a control signal for the charging unit. The relationship between U B U GAS  and the proportion of the charging current resulting in "gassing" may be represented by a linear approximation. Fig. 3 (not shown) and this fact is utilized to provide a signal represented gassing current from an amplifier (15) having two values of input resistance (R16, R17) switched by a Zener diode (D3). The amplifier output signal is integrated and used to provide a warning of excessive loss of electrolyte due to "gassing". In this case, the effective charging current is obtained by subtracting the gassing current from the total charging current. Further, the discharge current is also averaged before being integrated.

Class 89(3) A device for applying clenching-pressure to secure pronged-clips at the intersections of reinforcing-members of containers, comprises a frame, e.g. of rods 1, Fig. 1, each pivoted at one end to a frame 2 and having a jaw 3 pivoted thereto at the other end. The jaws also have pivoted-connection with a member 5 movable against a spring 9 to pivot the jaws inwardly simultaneously, for applying said-pressure. The member may be moved by cams 6 rotated by handles 7. In a modification, the jaws have curved-portions for co-operation with a conical-head on member 5, so that downward-movement of the member pivots the jaws inwardly. In another arrangement, the jaws 11, Fig. 2, are pivoted to a frame 12 and to links 13 pivoted to a ring 14. The ring is movable-downwardly against a spring 15 by, e.g. pneumatic or magnetic-means, to move the jaws inwardly. A number of devices may be coupled together so as to apply pressure on all the clips in one container, in a single operation.

Abstract: 957,258. Frequency modulation. NIPPON ELECTRIC CO. Ltd. Nov. 2, 1962 [Nov. 8, 1961], No. 41610/62. Drawings to Specification. Heading H3R. Two oscillators of different frequency each include in their frequency determining circuits a back biased semi-conductor variable capacity diode or ferrite variable inductor to which modulation is applied to alter the two frequencies in different directions, so that the difference frequency of the two frequencymodulated oscillators taken from a mixer is itself frequency modulated. By selecting the frequencies, tank circuit capacities and bias on the semi-conductors it is shown that non- linearity of the frequency modulation over a wide frequency deviation range can be eliminated from the difference frequency output. The mixer may be a ring modulator. The modulation input may be applied in push-pull to the oscillators.
