Title: Improvements in and relating to circuit arrangements for filtering out a fluctuating frequency from a frequency mixture
IPC: H04B1/10
Filed: 1936-09-11
Abstract: 478,605. Echo distance - measuring apparatus. SIEMENS APPARATE UND MASCHINEN GES. Sept. 11, 1936, No. 24840. Convention date, Oct. 9, 1935. [Class 118 (ii)] [Also in Groups XL and XXXIX] Apparatus for selecting a desired sound or other vibration out of a background of noise or other mixed vibrations comprises a set of filters 3 having contiguous pass bands and provided with current-limiting devices 4 for eliminating noise currents. The invention is applicable to depth-sounding from aeroplanes. In the latter instance the echo is received by a microphone 1 and the sound currents are transmitted through an amplifier 5 to a receiver 6. The pitch of the echo may vary as a result of the Doppler effect and for other reasons, and the total pass band is accordingly widened by tuning the filters 3 to have contiguous pass bands. Attenuating networks 4 are provided for eliminating noise currents, which are at a lower energy level than the current corresponding to the desired sound. In a modification, Fig. 2 (not shown), the threshold at which the current-limiting device acts is automatically varied in accordance with the noise level by means of rectified microphone current. Alternatively the threshold may be adjusted manually.

Title: Method and apparatus for winding up travelling webs
IPC: B65H18/20
Filed: 1969-05-15
Abstract: 1,260,004. Winding webs. A. AHLSTROM OSAKEYHTIO. 15 May, 1969 [15 May, 1968; 26 June, 1968], No. 24849/69. Heading B8R. In a web winding machine the pressures acting on the roll being wound are controlled so as to ensure the formation of a uniform roll. As shown, a roll 14 is supported on two winding rollers 10, 12, one of which is driven, whilst a rider roller 18 is urged against the top of the roll 14 by an arrangement including an hydraulic cylinder 28; the rollers 10 and 12 are each arranged so that deflection of the roller axis under stress is compensated for, whereby straight line contact between roller and roll is always maintained despite increase in weight of the roll during winding and despite the fact that the position of the contact line moves, relative to the centre of the winding nip between the rollers 10, 12, as the diameter of the wound roll increases. Thus, roller 10 comprises a rotatable shell 30, a hollow interior and a supporting beam 34 which takes up the bending stresses; roller 12 is similar, and the beams 34, 36 of the two rollers are linked by a pantograph mechanism to the core 15 of the roll so that the beams are turned, as the roll diameter increases, to compensate for the changing pressures on the rolls, whereby straight line contact between the roll and each roller is maintained; at the same time the pantograph mechanism operates a valve 78 which controls the supply of oil to the cylinder 28 so that the pressure applied by the roller 18 decreases as the weight of the roll increases, whereby the load on the rollers 10, 12 is maintained constant to ensure uniform winding tightness from layer to layer. Another valve, similar to valve 78 also controls the pressure in expansion chambers 54, 56 provided in the rollers 10, 12 and adjustment of this pressure enables the winding tightness to be varied from layer to layer in a predetermined manner. Modified arrangements for the mechanical linkage between beams 34 and 36 and for the support mechanism associated with the roller 18 are described with reference to Figs. 3 to 9 (not shown). The machine may also include a roller associated with a pressure cell for detecting variations in tension of the web supplied to the roll, the pressure in chamber 56 being automatically adjusted in dependence upon these variations.

Abstract: 1304741 Semi-conductor devices MATSUSHITA ELECTRONICS CORP and MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 22 May 1970 [28 May 1969] 24874/70 Heading H1K The breakdown voltage of a PN junction 3 is raised by extending the space-charge region at the surface emergent part of the junction: the two narrow metal annuli 8, 9 on the silicon oxide passivation are connected to the ohmic contact 7 by narrow conductive tracks or by external connections so that the depletion layer is extended into the higher resistivity one 1 of the two junction-forming regions 1, 2. The use of narrow annuli gives the same effect as known extensions of the ohmic contact but gives less chance of failure caused by extension of deposited metal through faults in the passivation. The electrodes need not be continuous so long as the depletion layer beneath them is.

A filler container is made by first injecting a plastic material from a cylinder 9 into a two part mould 3, 4, having a filling duct 29, a rod 90 is then lowered to break off the sprue, and the duct 29 is withdrawn. The injection cylinder and mould part 3 are then moved along rails 37, Fig. 1, plan to free the injected material from the part 3 and leave it in the part 4. The part 4 is then rotated to bring it opposite a mould 68 and a filling cylinder 50 is slid along rails 67 to engage the mould parts 4 and 68, and filling material is injected into the plastic material to blow it out into the shape of the mould. The filling material is fed from a tank 51 through a non- return valve 62. After filling, the cylinder 50 is slid back along its rails and the mould part 4 is returned by a spring. Arms 44, 45, and 46 are then rotated to bring the part 68 opposite a mould part 70, where a piston 74 injects plastic material through a duct 112 to seal the container. After retraction of the mould part 70, the arms are again rotated to bring the mould part 68 to a point where the duct 87 is open to a supply of compressed air, which ejects the finished container from the mould. In modifications, the injected plastic material may be originally in hollow form, the injection filling and sealing devices may be arranged in a vertical instead of a horizontal plane, and the container may be sealed by squeezing or stretching its end.
