Filed: 1962-10-09
Abstract: 984,666. Rollers. HERR EQUIPMENT CORPORATION. Oct. 9, 1962, No. 38212/62. Heading F2U. [Also in Divisions B3 and B6] Apparatus for winding strip material comprises a rotatably mounted drum having a generally spiral peripheral surface with circumferentially adjoining portions offset different distances from the drum axis to provide a step for receiving the leading edge of the strip to be wound. The drum comprises a rotatable arbour 10 to which is secured an arcuate segment 13 having pivoted thereto at 14 arcuate drum segments 15, 16. These are expanded by radial movement of a wedge member 18 caused by axial movement of a rod 23 formed with inclined surfaces engaging pins 22 on the member 18. The end of a strip 5 to be wound is gripped between a serrated surface 20 on the member 18 and an inclined surface 17 of the member 15, the arrangement being such that in the expanded state of the drum a radial step of a depth substantially equal to the thickness of the strip 5 is formed where the segment 15 meets the member 18, this prevents bumps forming in the overlapping turns of the strip 5 as it is coiled. The drum in its expanded state has a generally spiral periphery. Stops 25, 27 on the arbour 10 and segment 15 interengage to limit inward and outward movement of the segment 15.

Abstract: 1284018 Carrier frequency generators; frequency multipliers LICENTIA PATENTVERWALTUNGS-GmbH 10 Aug 1970 [12 Aug 1969] 38415/70 Headings H3T and H4R In a method of producing a harmonic of a fundamental frequency, e.g. for use as a carrier frequency in a carrier frequency system, the fundamental frequency is converted to a square wave or pulse stream of the same fundamental frequency and applied to a selection device, e.g. a tuned circuit, tuned to the desired harmonic and which shifts the phases of the adjacent harmonics in opposite directions by the same amount so that they appear as modulation, at the fundamental frequency, of a carrier at the desired harmonic frequency. The resulting signal is then converted to a square wave at the required frequency by amplitude limiting, triggering, or gating; which removes the modulation. The process may be repeated to improve the purity of the required frequency. The harmonic selector is suitable for realization as a printed or integrated circuit.

As shown in the Figure, the valve i is withdrawn from the supply conduit c by the application of a match near the opening g. The cool base of the attenuated flame q cannot supply enough heat to maintain the valve i open. The necessary heat is therefore supplied by a number of small flames s provided by slits in a boss t adjacent the opening g. The valve i is urged open against the natural tendency of the diaphragm by a spring k abutting a partition wall m clamped with the diaphragm to the casing a. A cock p also controls the supply to the burners o. Igniting gas which byepasses the valve i may be supplied by a pipe v. In a modification, a small pipe branching off the casing a is led round the edge of the diaphragm to provide a small flame near the opening g. In another form, flames issuing from several small apertures in the diaphragm are deflected towards the latter by a small baffle plate spaced from it. In this form, there is no partition wall and a disc or leaf spring on the valve spindle tends to close the valve.

Abstract: 1,105,717. Selective signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 8 Sept., 1966 [15 Sept., 1965], No. 40129/66. Heading G4H. In a digital-to-analogue converter having a non-linear characteristic comprising fourteen straight line segments (Fig. 2, not shown) divided into seven symmetrically disposed pairs each segment of a pair having the same slope, firstly the top most significant four bits of a seven-bit input signal are decoded to produce a voltage corresponding to the bottom end point of a particular segment, secondly the remaining three bits are scaled in accordance with the slope of the selected segment and decoded linearly, and finally the two voltages obtained are summed. The two centre line segments (which have the same slope) are each selected by two different combinations of the top four bits. Thus, effectively they are selected by particular combinations of the top three bits, and for these two straight line segments the bottom four bits are decoded linearly; i.e., in general each straight line segment is divided by eight equally spaced points, but the centre two are each divided by sixteen. The top four bits are arranged, by switching networks not described, to cause 0, 1 or 2 units of current to be injected into the top six rungs of a ten-rung resistor ladder attenuator, so that its output voltage corresponds to the bottom end of the particular straight line segment which they represent. The bottom three bits (four of the centre segments) are arranged, by switching networks partly described (Fig. 5, not shown), to inject 0 or 1 units of current into a group of three (or four) adjacent rungs of the ladder attenuator, the particular group being selected by the top four (or three) bits, so that the resultant output voltage produced by the ladder is the sum of a voltage representing the bottom end of a segment and a voltage representing a portion within a segment. The use of the decoder in a feedback encoder is mentioned.

Abstract: 855,935. Discharging batteries; protective arrangements. SVENSKA ACKUMULATOR AKTIEBOLAGET JUNGNER. Dec. 27, 1957, No. 40220/57. Class 38 (4). In order to prevent the destruction of one or more of a number of series connected battery cells by the excess gas pressure generated should the cell or cells begin charging with reversed polarity due to the cell or cells becoming fully discharged before the remainder when the battery is discharging there is. provided means to short-circuit the cell or cells when the gas pressure in the cell or cells rises above a certain limit or when the polarity reverses. An hermetically sealed cell 1 which forms part of a battery of such cells series connected, is normally charged from a source 7, 8 over a polarized relay 15, the armature 16 being unattracted during charging. When the battery is discharging the current direction through the operating winding 17 of the relay 15 is such as to cause attraction of the armature 16 so that the contact 13 moves into the vicinity of a contact 11 responsive to the gas pressure in the cell 1. Should the cell now become discharged before the remainder of the cells in the battery the cell 1 will tend to charge with reverse polarity thereby creating a large evolution of gas within the hermetically sealed casing such that when the pressure reaches a predetermined value the contact 11 will be moved into contact with the contact 13 thereby shortcircuiting the cell 1 preventing damage thereof. In another embodiment the polarized relay 15 is provided with two windings in a mutually aiding sense, one of which windings is responsive to the terminal voltage of the cell and is serially connected with a half-wave rectifier to make itsoperation current direction responsive.
