Abstract: 1,186,352. Counters. ENGLISH ELECTRIC CO. Ltd. 29 June, 1967 [14 July, 1966], No. 27121/67. Divided out of 1,186,351. Heading G4A. An electrical circuit arrangement responsive to electrical signals of a first and second type, e.g. pulses on one of two leads 16, 18 (Fig. 1) includes a store 10 to which the signals are fed, each signal of one type entering the store cancelling a signal of the other type stored therein, and two further stores 12, 14 to which signals of the first or second type are respectively fed when the first store 10 is filled with signals of either the first or second type. In the embodiment described for measuring the net flow of electrical energy at a point, the flow of energy towards the point is represented by pulses on input line 16 and the flow of energy away from the point is represented by pulses on lead 18. The first pulses being fed via a delay circuit 24 to count the storage counter 10 in an upward direction and the second pulses being fed by delay circuits 32 to count the counter downwards. The counter may count from one to five a signal on line 36 enabling gate 20 when the count is " five " so that further pulses on line 16 are accumulated in counter 12 and a signal on line 38 enabling the gate 28 when the count is " one " so that further pulses on line 18 are accumulated in the counter 14. The difference between the count in the counters 12 and 14 gives an indication of the next flow of electrical energy at the point. The counter 10 comprises four bi-stable circuits 40-46 (Fig. 2A) each comprising a pair of transistors and being in its " one " state when its left-hand transistor is non conducting and in its " 0 " state when its right-hand transistor is non conducting. Pulses on line 26 from monostable delay circuit 24 render the left-hand transistors of the circuits 40-46 non conductive sequentially whilst pulses on line 34 from the second delay circuit 32 render the right-hand transistors non conductive in the reverse order.

Title: Improvements in or relating to window stays
IPC: E05C17/18
Filed: 1935-10-01
Abstract: 463,563. Window-stays. TENNANT, W. J. (Naamlooze Vennootschap Ijzerhandel 1. M. de Vries) Oct. 1, 1935, No. 27124. [Class 65 (i)] A stay for a window moving on a horizontal axis comprises a slit tube 3 with a series of notches along the slit which tube is horizontally pivoted to the window and slidable over a pin 13 on the window sill and can be rotated so that any one of the notches engages the pin, the tube taking up a varying inclination to the horizontal during the sliding movement. The pin 13 consists of a headed bolt 15 screwed into a short cylindrical guide piece 21 which slides inside the notched tube and the stem of the bolt passes through an enlarged aperture 16 in a bracket plate 17 fixed on the window sill; thus the pin is able to adapt itself to the varying inclination of the stay as the window is opened. The notched tube has a handle 2 by which it can be rotated. A cover tube 4 is fitted over and retained on the notched tube. This cover tube is pivotally attached to the window by means of a spindle 5 rotatable in a sleeve 6 which is mounted by horizontal trunnions 7 in a bracket 9 on the window. To prevent rattling of the device the upper end of the spindle 5 carries a cam 10 whereby, when the window is closed and the stay is swung to lie parallel with the window, the top end of the spindle is moved away from the window and therefore the lower end and the notched tube are moved towards the window thereby pressing the pin 13 against the inner side of the enlarged aperture 16 in the bracket plate 17. When the stay is swung to the parallel position and clamped, the window is firmly closed by reason of the stay pivoting about an abutment 19 provided on the bracket plate. Specification 449,048 is referred to.

Means for securing or closing a bag which has a mouth consisting of two registering edges and is made from flexible polymeric synthetic resin, comprises a strip of deformable metal foil, such as aluminium, backed with an adhering vegetable sheet material, such as paper or thin fabric, which is secured by an adhesive along one outside edge of the mouth of the bag, so that in use the backed foil may be folded over the two contiguous edges at the mouth to close the bag. Further folds may be applied to roll the folded metal strip within the bag material. Preferably the length of the backed strip of foil is greater than the width of the bag so that it projects laterally beyond the edges and, after bending the strip along its longitudinal centre line so as to overlap the mouth of the bag the projecting ends are folded inwardly on to the body of the bag. The invention is applicable to extruded tubular stock that is severed into bag lengths and closed at one end by hot pressing or high frequency welding. The metal foil may be secured to the backing of paper or fabric by adhesive. Apparatus for applying the backed foil to the outside edge of the mouths of a series of bags arranged side by side on a table comprises a carriage provided with a gripper for drawing a length of backed foil from a reel and over an adjacent perforated spindle which applies a thin layer of adhesive to that half of the backing strip which is to make contact with the bag edges, the carriage being drawn over the said edges and then lowered so that a roller or presser shoe carried by it comes into pressure contact with the backed foil during the return movement of the carriage. A vertically movable frame then descends to sever the backed foil at a distance of about half an inch from each longitudinal edge of the bags. The bags may be printed upon by means carried by the vertically movable frame.
