[Class 16] In a manifolding book-keeping system, especially in connection with wages, in which one or more of the sheets on which entries are to be made are gummed on the reverse side and composed of detachable strips for attachment to cards or other account forms and wage envelopes, the sheets, cards or account forms, and envelopes are provided with stripes of selfadhesive, such that when the detached strips of the sheets are superimposed thereon and pressed they will adhere thereto. The sheet A, which is the second one in the manifolding operation, has narrow bands b of self-adhesive, and the major portion is divided into strips by lines a of perforations such that each strip has adhesive at its top and bottom edges, and a space c devoid of adhesive. To obviate the use of carbon papers, the spaces c on the reverse side of the sheet A may be coated with carbon. In manufacture, the sheet may be first coated all over with adhesive, and then coated with carbon at the spaces c, or the sheet may be carboned all over, and the stripes of adhesive subsequently applied. The third sheet in the manifolding operation may be coated all over with or have stripes of adhesive, and is intended to be divided up entirely into strips. The strips from the sheet A are to be stuck on a wage card having stripes of self-adhesive on each side for receiving the strips, and this wage card is stored in a folded sheet bearing particulars relating to the wage card. The wage envelopes have a stripe of adhesive on each side to receive the strips from the third sheet, which strips fold around the envelopes to seal the closing flaps. To prevent these envelopes adhering to each other during storing, the stripes on alternate envelopes are offset from those on the preceding ones.

Abstract: 539,406. Counting-apparatus. BOULTON PAUL AIRCRAFT, Ltd., and COX, J. H. April 26, 1940, No. 7495. [Class 106 (i)] An electric impulse counter comprises a spring controlled toothed drum held a gainst a stop and engaged by an actuating pawl and a retaining pawl, the actuating pawl being actuated by the armature of an electric motor when the armature is displaced in one direction from a normal position in response to each of the impulses to be counted, and tripping means for both pawls, effective upon the reversed displacement of the armature to trip the pawls and allow the counter to return to zero position. As shown in Figs. 1 and 2, a counter wheel 1 is loosely mounted on a shaft 13 and is normally held by a spring 23 with an abutment 24 engaging a stop 25. The shaft 13 supports the laminated armature 6 of an electric motor with two armature windings. 2, 3 and associated field windings 4, 5. Two field magnets 7, 8 of arcuate form and laminated have pole pieces 9 ... 12 projecting radially towards the armature. To the armature is secured an arm 14 carrying an actuating pawl 15 and, at its opposite end, an abutment 16 disposed against the tail end of a retaining pawl 17. The normal position of the armature is maintained by a spring 20. The windings 2 and 4 are electrically connected to a pair of input terminals for the impulses to be counted and drive the counter anti-clockwise in Fig. 1. The movement being limited to one step by a suitable stop 22. The windings 3 and 5 are electrically connected to a second pair of terminals in a resetting circuit whereby the armature is actuated in the reverse direction to retract the actuating and retaining pawls whereupon the spring 23 returns the counter wheel to zero position. A mutilated portion of the teeth of the wheel permits the actuating pawl to oscillate if for any reason the pawl continues to operate after the wheel has reached the limit of its travel. The device may be applied to a machine gun for counting the number of rounds fired and the re-setting circuit may be completed on the application of a loaded magazine to the gun. The re-setting circuit may be completed manually by the operation of a push button or lever. According to the Provisional Specification the indicator drum may carry an abutment to actuate the switch and complete the re-setting circuit when the drum reaches the end of its travel.

Title: Improvements in or relating to electrical frequency responsive circuits
IPC: H03J7/04
Filed: 1944-04-27
Abstract: 585,588. Frequency modulation ; automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 27, 1944, No. 7855. Convention date, April 27, 1943. [Class 40 (v)] A frequency-discriminating circuit comprises one or more triode valves with a cathode impedance for providing inverse feed-back and with an anode impedance, one of which is variable with frequency, the circuit being-so arranged that on the application of varying frequency voltages, voltages of oppositelysloping amplitude-frequency characteristics are developed. Fig. 2 shows a F.M. receiver with the I.F. signals applied to one grid of a pair of triode valves coupled by a common cathode resistance 2. The anode of the first triode is connected to a network Z which is series resonant at a frequency F2 and is parallel resonant at a frequency F1 so that the output voltage across the network has the form shown in full lines in Fig. 3 when plotted against frequency of input. The second triode has its anode connected to a resistance 7, its grid being connected to the earthed end of the cathode resistance 2. High voltage across Z is accompanied by low voltage across the resistance 2, and the frequency characteristic of the output across the resistance 7 thus takes the form shown in dotted lines in Fig. 3. The respective output voltages are applied to balanced rectifiers 16, 17 and the resultant voltage across the load resistances 18, 19 may be passed to a signal reproducer or may be smoothed and utilized for automatic tuning. The network Z may comprise a series connection of inductance and capacity resonant at the frequency F2 shunted by an inductance to form a closed circuit of resonant frequency F1 (Fig. 3a, not shown). In a further modification (Fig. 4, not shown), the impedance Z is in the form of a parallel circuit resonant at the frequency F2, and the resistance 7 is replaced by another parallel circuit resonant at the midfrequency Fc. In Fig. 5, a single screen-grid valve 40 is used with its cathode circuit resonant at the frequency F2 and its anode connected to a resistance 60, output to the rectifiers being taken from the anode and cathode respectively through condensers A, B.
