Title: Audience sampling system
IPC: H04H1/00
Filed: 1968-01-09
Abstract: 1,209,343. Audience survey systems. TELEVISION AUDIT CORP. Inc. 9 Jan., 1968 [11 Jan., 1967], No. 1277/68. Heading G4H. In an audience survey system of the type in which the frequency of the signal transmitted from a receiver represents the programme to which it is tuned, different frequencies are fed to separate channels, one of which is shown in Fig. 1, each channel being disabled when there is interference in the received signal. In the embodiment described, frequency signals associated with the preselector 16 of the channel of Fig. 1 are passed from an antenna on an aircraft or preferably on a tower to a mixer 18 which also receives a signal from a voltage controlled oscillator 46, fed with a sweep signal as the antenna rotates. The sweep signal is also fed to a blanking circuit 52, including a counter (62, Fig. 3, not shown) and diode matrix (66), the latter being programmed so that, when the oscillator is sweeping through a known interference frequency, e.g. that of an interfering F.M. station, a switch 42 is closed to inhibit the channel. The intermediate frequency signal from mixer 18 is fed via a crystal filter 20 and an amplifier 22 to a further mixer 24 and to a level detector 38 which closes the switch 42 if the input signal is greater than the expected signal from a local oscillator. The output of mixer 24 is fed to a further filter 28 and detector 32 which only delivers an output pulse to a counter associated with the channel if the signal lasts for a predetermined time. In this way short signals due to, e.g. ignition noise are not counted.

Filed: 1948-01-15
Abstract: An elastic product, which may be cured to give an elastomer, comprises a polysiloxane containing both the structural unit -(CH3)2.SiO-and the structural unit -CH3.H.Si.O-, which has been treated with ferric chloride, an alkali metal hydroxide, sulphuric acid or phenyl phosphoryl chloride, as elasticizing agent.  The initial polysiloxane may be prepared by the cohydrolysis of a mixture of the corresponding hydrolysable silanes containing from 50 or 70 to 97 mol. per cent of a dimethylsilane using water or by admixing the separate hydrolysis products.  The initial polysiloxane is contacted with 0.5 to 5 per cent by weight of the elasticizing agent, and allowed to stand at room temperature or heated to give an elastic product.  This may be compounded with vulcanizing agents and fillers, e.g. titanium dioxide, ferric oxide, antimony oxide, asbestos, comminuted glass fibres, whiting, lithopone, tale, zinc oxide, powdered silica, and cured to an elastomeric composition. In examples, dimethyldichlorosilane and methydichlorosilane as mixtures in varying proportions were hydrolysed and treated with phenyl phosphoryl chloride to give an elastic gum which was compounded with titanium dioxide and, optionally, with benzoyl peroxide to give various elastomeric compositions.

Title: A method and apparatus for improving the physical properties of metal members
IPC: B21H7/00
Filed: 1954-01-18
Abstract: 785,533. Altering physical structure; making engineers' toots and gun barrels. WLODEK, T. W. Jan. 18, 1954 [June 11, 1953], No. 1373/54. Classes 83 (2) and 83 (4). A method of improving the physical or stress sustaining properties of highly stressed metal members such as drill steel, drill rods, drill pipes their connectors and attachments, and their welds, joints, fillets, threads and metallurgical notches comprises applying pressure at spaced-apart intervals over all or part of the surface of the member, at temperatures below the recrystallization temperature, to plastically deform the metal at spaced-apart portions of the member, into permanent grooves or depressions to a depth of between one thousandth and one sixteenth of an inch and leaving juxtaposed portions of metal of the member in its normal undeformed elastic form, thus creating in the member locked-in residual stresses to enable said member to resist fatigue, corrosion fatigue and fretting. Fig. 1 shows a member 1 provided with grooves 2 formed according to the invention to leave undeformed portions 3 of metal in its original elastic form and plastically deformed metal in areas A adjacent the grooves. Examples of groove patterns are shown in Figs. 2 to 6 and 8 and their cross-sections are shown in Figs. 9, 10 and 11. Apparatus for carrying out the invention is attachable to a lathe and comprises a base 18 (Fig. 12) and fixed and movable supports 19 and 20 respectively accommodating sleeves 22 within which are slidably mounted spring-loaded contoured rollers 27 which act on the workpiece 30. The rollers may have contours as shown in Figs. 12a to 12i. Alternatively, the rollers are hydraulically operated by pistons 34 (Fig. 13). Apparatus for treating the interior surfaces of hollow members, e.g. cylinders, hollow shafts, marine shafts, tubes, gun barrels, drill pipes are shown in Figs. 13a to 13d. The rollers 27 are carried either by a lazy tongs mechanism operated by adjustable spring pressure (Fig. 13a) or by hydraulically operated pistons 34 (Fig. 13b). In a modification (Fig. 14) the roller 37 is spring-loaded and the roller 38 is mounted on a support 39 the pressure being applied to the support through a lever 41 by a spring arrangement 42. The apparatus is mounted on a lathe having a driving head 43. In another embodiment (Fig. 16) the apparatus consists in a base 47 supporting a movable member 49 slidable in a support 48 said member carrying a roller 60 on an arm 51 and a spring- loaded sleeve 54 carrying a roller 56. When connecting a drill bit 67 to the treated end 63 of a drill rod 64 (Figs. 18 and 22) a metal thimble 66 is placed over the treated end to protect the grooves from fretting and corroding. Specification 785,534 is referred to.

Title: Temperature control circuits
IPC: G05D23/24
Filed: 1975-01-06
Abstract: 1468829 Temperature control ADCOLA PRODUCTS Ltd 6 Jan 1975 [11 Jan 1974] 01379/74 Heading G3R Supply of A.C. power to a heater element 1, e.g. in a soldering instrument, is controlled in accordance with temperature by means of a circuit whose essential components are: a temperature sensor 2; a switching device 17 which changes its state in response to the detection of a too-low temperature; a transistor 20 which is rendered non-conductive when said change of state occurs; and two SCRs 26, 29 which become conductive whenever the transistor 20 is non-conductive. Conduction of the final SCR 29, which is preferably a triac, delivers heating power to the element 1. The temperature-responsive means operates as follows. The resistance of the sensor 2 determines the maximum value which the base-emitter voltage of the transistor 8 will attain during positive half cycles of the applied A.C. and the voltage across the resistor 12 is relatively low or high according as the transistor 8 is conductive or not. Hence the input to the trigger gate of switch device 17 constitutes pulses whose amplitude depends on the sensed temperature. It is arranged that device 17 is triggered in each positive half-cycle so long as the detected temperature is too low, thus supplying power to element 1 as above described. The capacitor 32 is charged during each such positive half-cycle and its discharge in the succeeding negative half-cycle re-triggers the triac 29.
