Title: Stabple driving tool
IPC: B25C5/15
Filed: 1973-06-04
Abstract: 1394174 Stapling machine A ABRAMS 4 June 1973 [5 June 1972] 26610/73 Heading B4C A staple driving tool comprises a body, a coil 130 in the body, means to fix the coil to the body, a central hole in the coil, an armature 85 having its lower end slidably mounted in the hole and guided thereby for vertical reciprocation, and upper guide means 81 fixed to the body to slidably receive and guide the armature for vertical reciprocation. A member 97 is fixed to the armature and disposed between the coil 130 and the upper guide means, and, offset forwardly of the armature, is a staple drive blade 100 mounted on the member 97 and disposed at the front of the body. Means is provided on the body to guide the driven blade 100 for vertical movement with the armature in spaced parallel relation thereto. As described, electric current is fed to the tool by a cable 124 to supply a circuit including the coil 130 a microswitch 28 and a safety switch 119. In use the tool is placed against a workpiece so that arms 112<SP>1</SP> pivot about a bolt 45 and cause an arm 115 to close the safety switch 119. A trigger 18 is then pulled to close the microswitch 28 and thus energize the coil 130. This causes the armature 85 to be drawn downwardly so that the blade 100 ejects a staple from a magazine 110. The armature is then raised by spring 90. If the trigger is held depressed the electrical circuit is such as to cause repeated energization of coil 130 at predetermined time intervals.

Class 52(ii) An adjustable reclining chair wherein a seat, a back rest and a portion of the seat support are included in a constrained complex linkage having movable links and at least one stationary link is characterized in that a controlling link, pivoted at its rear end to a movable link and, forwardly thereof, to a member swingably mounted on the front part of the seat, has an extension which is pivoted to a leg rest or to a part of a leg rest which is in slidable connection with the swingable member whereby the leg rest or the part thereof may be moved away from the seat when the movable members of the chair are brought from the sitting position into the reclining position. As shown in Fig. 1 the seat 28 is pivoted at each side to the support 20 at 30 on which pivot is also mounted a link 32 rigidly connected to the back rest 34. The link 32 is pivoted at 36 to a connecting link 38 which is pivoted at 40 to a front connecting link 42 pivoted at 44 to the seat 28. Pivoted also to the support 20 at 48 is a guiding link 46 pivoted to the connecting link 38 at 50 and having an extenison 60 pivoted at 62 to a controlling link 58. The controlling link 58 is pivoted to the leg rest 68 at 66 and also to a swingable member 52 which at one end is pivoted to the seat at 54 and has at the other end a slot 72 in slidable engagement with a pin 70 on the leg rest 68. When the occupant, by weight transference, moves the chair from sitting position shown in full lines to full reclining position shown in dotted lines the leg rest 68 is moved to position 68<SP>1</SP> and in the process is moved forwardly to a greater distance from the seat than is normal in sitting position. The linkage may be arranged in various arrangements. Fig. 2 shows an arrangement wherein the seat 128 and back rest 134 are pivoted at points 130, 131 on the support 120 spaced from one another and the leg rest is in two parts 167, 169 slidably connected to one another, the controlling link 158 being pivoted to the swingable member 152 at, 156 which swingable member is rigidly connected to the upper part 167 of the leg rest while the extension 164 of the controlling link 158 is pivoted at 190 to a bar 186 secured to the lower part 169 of the leg rest whereby as the chair moves from sitting position to reclining position the lower part 169 of the leg rest moves away forwardly from the upper part 167 of the leg rest.

Title: Improvements in and relating to wireless telegraphy and telephony
IPC: H01Q21/26
Filed: 1930-09-10
Abstract: 362,530. Directive wireless signalling. MACKENZIE, W. B., RAWLINSON, W. F., and BORROW, R. L. A., H.M. Signal School, Royal Naval Barracks, Portsmouth. Sept. 10, 1930, No. 27091. [Class 40 (v).] Two normallydirective aerials, such as a ship's installation of two crossed frames, can be made, if necessary, non-directional by combining the output from the two frames in a common circuit through separate coupling-channels in which a phase difference of 90‹ is introduced. As shown in Fig. 1 the aerial circuit A, C1, E is tuned to a frequency slightly higher, and the aerial circuit B, D1, F to one slightly lower, than the signal frequency to which the common circuit G, C is tuned. The 90‹ phase difference is obtained by relative adjustment of the condensers C1, D1. Equal amplitude is secured through the couplings E, F. The current in the circuit G, C is independent of the direction of incidence of the wave. Fig. 2 shows an alternative arrangement in which the voltage between the points M, N is 90‹ out of phase with the voltage across the points N, P owing to the relative disposition of the resistance-capacity coupling elements R1 C3, R2, C4. The combined currents are applied to the grid of the amplifier V5. Alternatively, as shown in Fig. 4, the necessary 90‹ phase difference is imparted by means of a local heterodyne oscillator O, the output from which is fed to two valves V3, V4. The anode circuit of V3 comprises an inductance M, and the output is coupled at K both to the aerial A and input circuit G, C; whilst the anode circuit of V4 comprises a resistance N and is coupled at L to the aerial B and input circuit H, D. The combined non- directional input is fed to a common amplifier V5. In a modified arrangement the 90‹ phase difference is introduced in the intermediate-frequency stage of a superheterodyne receiver.

Title: Improvements in and relating to laminated link type v-belting
IPC: F16G5/16
Filed: 1964-07-01
Abstract: 1,104,601. Belting. C. W. JONES, and J. C. JONES. 30 June, 1965 [1 July, 1964], No. 27093/64. Heading F2Q. Each link of a 3- or 4-link laminated type V-belt has a connector pin attached to the widest end of the link and is formed with connector holes 6 slotted longitudinally towards the connector to ensure that all the connector pins (5) and links carry an equal load thereby giving greater belt service life. The connector pin may be a stud (1) riveted to the link (Fig. 2, not shown) or, in Fig. 4 (not shown), a screw (5), spacer tube, preferably " D "-shaped to increase resistance to side pressure, and lock-nut with appropriate washers, or, alternatively an arrangement similar to Fig. 4 but with the spacer tube shortened to abut a washer on the link face on the side opposite to the nut and other washers. The elongation of the slotted holes is determined by a given formula based on an experimental factor which reduces by half for each hole, the maximum elongation being on the hole at the opposite end of the link to the connector pin. The slotted holes may be shaped at their elongated ends to facilitate fitting the connector pins during belt assembly. Thin links of woven nylon covered with neoprene rubber or other plastics material having a low coefficient of friction may be disposed between the links to increase the belt strength.
