Filed: 1963-02-08
Abstract: 1,003,586. Road machines. VRETENS MEK VERKSTAD A.B. Feb. 8, 1963, No. 5342/63. Heading E1G. A scraper or grader unit comprising a support bar and blade is pivotable about a vertical axis relative to the rear hitch of a tractor on which it is mounted, and retainable at a selected angle to the hitch by a catch which is released when the blade meets a stationary obstacle to allow the bar and blade to swing aside. As shown, a bar 5 is secured to a sleeve 4 pivotable about a vertical member 3 supported by a frame 2 secured to the three point hitch 1 of a tractor. Also pivotable about the member 3 is a member 31 a widened portion 32 of which carries flanges 36 flanking a recess 35. The bar 5 is resiliently and releasably linked to the member 31 by engagement of a knob 40, on a rod 39 slidably mounted in lugs 37, 38 on the underside of the bar 5, in the recess 35. Bolts 42 pass through a cross member 41 on the rod and springs 44 are braced between the bolt heads 43 and the lug 38. The blade is mounted on a shank 7 at an angle adjustable relative to the ground by means of a pivoted connection 12 and rails pinned at 19 to lugs 18 on the shank. The shank is journalled in a sleeve 8, itself limitedly rotatable relative to the bar 5, and is secured in selected position relative to the sleeve 8 by engagement of a pin 15, carried by an arm 16 mounted on the sleeve 8, in a hole 14 in a disc 13 secured to the shank 7. In operation, the bar 5 and the member 31 linked thereto are pivoted to the selected position about the member 3 and retained by bolts 34 inserted in holes 33 in the member 31 and holes 30 in a plate 29 fixed to the frame 2 and the blade 6 adjusted relative to the bar 5. When the blade hits a stationary obstacle, at any point where the resultant force tends to swing the blade about the vertical member 3, the spring-mounted knob 40 is released from the recess 35 allowing the blade to swing aside. When the obstacle has been passed, the bar is re-set manually, the knob 40 being guided by the flanges 36 into the recess 35.

Title: Tacking machine
Inventor: SWAIN ROBERT PADDY
IPC: A43D71/00
Filed: 1954-02-24
Abstract: 794,494. Nailing machines. STANDARD ENGINEERING CO., Ltd. March 31, 1955 [Feb. 24, 1954], No. 5412/54. Class 89(3) In a tacking machine tacks are fed from a container towards a raceway by means of a stream of compressed air. In Fig. 1 a portable hand held tacking machine is provided with a container G for the tacks, in which a blast of compressed air introduced tangentially of the container by a nozzle J blows the tacks around the container so that they fall on to a shoot K and from there slide into a raceway F. The air is supplied along a pipe H from a pneumatic operating cylinder A of the tack inserting mechanism as the driving plunger therein reaches the end of a forward stroke. A baffle M serves to direct the tacks into the shoot. The container is closed by a lid (not shown) and the compressed air escapes from the container through vents N. In Fig. 2 the tack feeding device is applied to a tacking machine suitable for fastening steel shanks to fibre backing, in which an anvil 23 is adapted to be raised by a pedal (not shown), to apply the work against the nozzle 4 of a pneumatic tack inserting device carried by a pivoted bracket 2 which is coupled to an operating valve 14 controlling the tacking device. Upward movement of the bracket 2 due to the raising of the anvil causes the valve 14 to open and thereby operate the tacking device. An additional compressed air pipe 22 which leads to the side of the tack container 15 is provided to remove from the shoot at the top of the raceway, by means of an air blast, any tacks which have not fallen correctly into the raceway. A tacking machine according to the invention may be mounted on a counterpoised suspension such as an arm permitting it to be swung to different horizontal and vertical positions.

Title: Improvements in or relating to radio transmitting systems
IPC: G01S1/02
Filed: 1939-02-20
Abstract: 525,359. Directive wireless signalling. KEAR, F. G. Feb. 20, 1939, No. 5526. [Class 40 (v)] An equi-signal course is formed along the line AB, Fig. 3, by energizing two non-directional aerials E, W in phase-opposition, simultaneously or in rapid succession, to produce reversed cardioid curves, the 180 degree phasing being due partly to the spacing of the aerials and partly to the phasing of the supply current. One method of continual excitation is shown in Fig. 5, where currents are applied from sources C, D to the aerials E, W, the latter also being coupled together through a transmission line 10. If the aerials are spaced apart by 90 degrees the electrical length of the line 10 must also be 90 degrees to produce the required phase-relation. Fig. 6 shows a method of successive excitation of the aerial lines 3, 4 from a single source 15 through a switch 18 which is keyed by A.N. or similar overlapping signals. If the two non-directional aerials E, W are spaced a half-length apart, and are energized simultaneously (a) by in-phase currents to produce one figure-of-eight field, and (b) by out-of-phase currents to produce another figure-of-eight field, the two fields will combine to produce the four-way course shown shaded in Fig. 10. Fig. 12 shows a method of feeding the two aerials simultaneously from sources 30 and 31, the line from the latter being crossed at 35 to produce a phase change of 180 degrees. Both sources may be suitably modulated by complementary signals. As shown in Fig. 13 the two aerials 50, 51 are connected through a bridge circuit so that current from the source C passes from arm 42 of the bridge through the transmission line 65, 66 (which introduces a phase lag of 90 degrees) to a coil 55 which supplies out-of-phase current to the aerials to produce a figure-of-eight field. At the same time, current is fed from the arm 43 of the bridge through leads 67, 68 to a tapping 71 on the coil '55, thereafter passing in series through the coils 52, 53 to ground at 69. This energizes the two aerials with in-phase current to produce a circular field, which then combines with the first field to produce a cardioid curve. Simultaneously current from the source D similarly passes through the bridge, so that at any moment the arm 42 of the bridge carries the sum of the two supply voltages, and the arm 43 their difference. As a result, two cardioids of reversed phase are radiated, and define two curves in space extending on opposite sides of the line joining the two aerials.

Filed: 1923-02-27
Abstract: 219,717. Switchgear & Cowans, Ltd., and Neep, G. H. Feb. 27, 1923. Protective arrangements for circuits which are normally insulated from earth comprise means whereby a faulty cable will be automatically cut out consisting of a winding in each conductor normally producing balanced forces upon a relay, or a currentless condition of the secondary of a transformer energized by the windings, and a tapping taken from each conductor to one side of a spark gap the opposite side of which is connected to earth. In the arrangement shown in Fig. 2 for a three-phase, system, the phases are connected to the load through separate windings 9, 10, 11 of a single transformer, the secondary of which is connected to the tripping coil of the circuit-breaker. Each phase is connected to a separate spark gap 20, 21, 22 or other electrostatic device the other side of which is connected to earth. Instead of using a single leakage transformer three current transformers may be used with their secondaries interconnected and the tripping coil connected across them so that normally no current flows through it. An arrangement for a direct-current, circuit is shown in Fig. 4. The positive and negative mains are reversely connected through a differential relay and are connected through a spark gap to earth. On disturbance of balance the armature 26 is attracted and the tripping coil closed. Specification 198,788 is referred to.
