Abstract: 687,651. Razor-blade magazines. GILLETTE SAFETY RAZOR CO. June 28, 1948 [June 30, 1947], No. 17286/48. Class 18 In a razor blade magazine from which slotted blades are fed alternately from opposite ends by finger pressure on the blades through an opening 27 in the magazine upper wall, a spring 29 urges the blades upwardly against projections 26 bordering the opening 27. The projections 26 maintain the blades below the top of locating studs 13, 14 and when a blade is withdrawn so that its inner solid end engages its respective stud, the adjacent projections 26 fit into the cut-away corners of the blade, permitting it to be raised by the spring clear of its stud for complete withdrawal. The slot of the issuing blade is engaged by a projection 25 extending into the respective exit, so that the blade is located clear of the magazine walls during the whole of the withdrawal movement. The magazine comprises a moulded integral top and side walls which are interlocked with and may be fused to a bottom wall 10. The spring 29 is introduced through a slot 16 in the bottom wall 10 after assembly of the magazine round a stack of blades a notch 17 permits the spring to be pressed into engagement with a shoulder 18 for retention in the magazine. Specifications 687,133 and 687,134 are referred to.

Abstract: 612,957. Electric resonators. HAZELTINE CORPORATION. June 11, 1946, No. 17467. Convention date, June 14, 1945. [Class 40 (viii)] A wave signal selector system comprises one or more wave-guides or resonators, means for adjusting their electrical length to tune the system over a relatively wide frequency range, and wave signal coupling means, which involve a resistance component which increases the width of the band-pass, connected at a point in the guide or resonators such as to provide maximum band width for the guide when it is adapted to resonate at substantially the mean frequency of its range. For this particular point of connection it is found that the band width will remain substantially constant over the whole range of adjustment. In the example shown, a selector system 13 is connected to an antenna 10 and a receiver or transmitter 15 and comprises two coaxial lines 16 and 17. They are tuned by pistons 23 and 24 with a common operating handle 25. Coupling elements 26 and 27 are positioned at points fulfilling the conditions above. The two lines are coupled by members 28 and 29 at points determined by similar conditions. Inductive coupling loops may be used instead of the capacity elements shown and hollow waveguides may be used instead of the coaxial lines. The tuning may be effected by telescopic sections of the inner conductor.

Abstract: 1526494 Lining reservoirs ATELIERS J HANREZ SA 29 April 1976 [9 May 1975] 17482/76 Heading E1T [Also in Division G6] A reservoir e.g. for corrosive liquids and preferably formed of reinforced concrete 1 is lined with metal sheets e.g. of stainless steel joined together by soldering so as to provide closed cross section drainage conduits 14 to allow the liquid in the reservoir to escape in the event of a leak without the liquid contacting the reservoir structure 1. Light weight concrete 15 may be infilled between the lining and the structure 1. A plurality of drain points may be provided so that any leaks may be traced to certain sections of lining. Leaks may be identified by pressuring the drainage conduits with liquid or gas and inspecting the lining for liquid leak or gas bubbles. Leaks may be stopped by additives in the liquid pressurising the conduits in test. The reservoir may contain boric acid solution from the primary circuit of a nuclear reactor.

Title: Improvements in or relating to electrical or electro-mechanical control systems of the error correcting type
IPC: H03H7/01
Filed: 1938-06-13
Abstract: 515,843. Television. BAIRD TELEVISION, Ltd., and NUTTALL, T. C. June 13, 1938, No. 17507. Drawings to Specification. [Class 40 (iii)] [Also in Group XXXV] The deviations of a variable frequency current from a standard frequency current are corrected by applying both to a detector whose output is a measure of the deviation, and applying the output to correct the variable frequency. According to the invention,. the output is applied through a low-pass filter so as to prevent fluctuations above a predetermined frequency in the standard frequency having much effect on the correction, and the filter produces a phase advance which is a maximum near the limiting frequency to prevent instability. Suitable filters are shown in Figs. 6, 9 ... 16 (not shown). The invention is applied to television (in which the variable frequency current is the scanning oscillator and the standard-frequency current is a mains supply), and to gramophones (in which the variable frequency current is derived from the turntable). The variable frequency may be derived from an oscillator whose frequency is determined by a condenser varied by an electromagnetic system under the control of a dash-pot.

Abstract: 1,056,159. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 27, 1965 [April 28. 1964], No. 17568/64. Heading H3P. In a pulse generator of the type described in Specification 1,053,656 in which a pulse forming network PFN is first charged and subsequently discharged through a load to generate a pulse and having a clipping capacitor C2 into which excess energy is diverted from the charging inductor L1, arrangements are made for limiting the rate of recovery of energy from the clipping capacitor C2. As shown, thyratron V2 is arranged to be triggered when the PFN voltage is excessive, so as to divert energy from L1 into C2 after which C2 is allowed to discharge slowly via L4 into C3 which in turn will discharge via D1, D2 and L2 into the PFN on subsequent cycles. This arrangement prevents oscillation of the smoothing circuit L3, C1 due to the resistance of the pulse generator becoming negative. In Fig. 7 (not shown) L4 and C3 are omitted, an inductor being included in the negative side of L2 and a capacitor being connected from the intermediate point of the inductors to the cathode of V2.
