Title: Improvements in means for connecting two or more separate mechanical units to each other, or one or more such units to a relatively fixed unit
IPC: F16B13/08
Filed: 1944-12-06
Abstract: 589,084. Stud fastenings ; bolts ; wall plugs ; hooks. FRENCH & SONS, Ltd., T., FRENCH, G. F., FRENCH, R., and WARBURTON, S. Dec. 6, 1944, Nos. 24378 and 32716. [Classes 44, 89 (i) and 89 (ii)] [Also in Group XXII] A bolt-like connecting means particularly for fixing articles to thin walls where access can only be had to one side, has a main body part and a pivoted section adapted to be tilted out of line with the main body after the passing through the hole. The fixing screw &c. is used to cause the tilting and to prevent the pivoted section from returning to the withdrawal position. The body part a, Fig. 1, is channelled out at its forward end and carries at this end a pivoted member b. A screw e engages a tapped hole in the solid part of the body, preferably near to one side. After insertion of the bolt, the screw is tightened tilting the part b and then passing behind it to prevent its return. The screw engages the front face of the wall by a washer and this may be formed as a picture hook d with a slot to receive a tongue a<1> on the bolt to prevent rotation. Either the end of the screw or the abutting end of the part b may be tapered. The end of the body may be slotted to mount opposed pivoted members b or the body may be hexagonal, instead of square, to mount three pivoted members. The bolt may be employed to connect plates f, Fig. 11, together prior to riveting, a washer g receiving the head of the screw. Two bolts a, Fig. 12, may be employed with a bracket h<3> to connect wall plates h<1>, h2 at right angles and the bracket may be provided with a third side, shown in dotted lines to secure a ceiling plate also. In a modification for use with a range of thicknesses of wall, the body part a, Figs. 15 and 19 is of channel section throughout, the flanges being inturned at a<2> to retain and guide a shorter channel part a<3>, the end wall of which is tapped for the screw a<7>. Interengaging depressions a<8>, a' on the parts effect further guiding and may limit the travel. The part a<3> carries the pivoted member a<4> and the screw a<7>, after turning the member a<4> into position telescopes the parts a, a<3> to effect clamping. The washer a<5> is formed to engage behind the part a as well as in front of the wall. In a further modification, the part a is dispensed with and the washer a<1> has a long rearwardly extending tongue that engages in the end wall of the part a<3>.

Title: Improvements relating to pile hammers and like percussion machines
IPC: E02D7/12
Filed: 1948-09-17
Abstract: 656,493. Percussive drills. BELL, N. G. Sept. 17, 1948, No. 24427. [Class 124] In a percussive hammer of the type operated as an internal combustion engine comprising a piston, stationary with reference to and supported by the object to be struck, and a reciprocating cylinder acting as a ram, the operating mechanism, for controllably supplying fuel to the cylinder, is mounted on a stationary part of the hammer to be struck by the ram and mounted above the ram in all positions of'the latter. As shown applied to a pile'driver, a piston 2, which may be double acting or single acting, is rigidly connected to a piston rod 3 to which a plate 15 is attached. Pumps 5 and 5a operated by hip cams 13 and 13a and lever 6 supply fuel from a tank 7 to injectors 4 and 4a and explosions which may be initiated by compression or by a sparking plug or both in combustion chambers 9 and 10 cause the cylinder to move relative to the piston, slots 11 being provided to act as inlet and exhaust ports and allow for the projection of the lever 6 and a bracket 12 supporting the fuel tank. A pipe 21 leading from a port in the lower chamber to a valve 22 in the upper chamber allows some of the air compressed in the lower chamber to be used for scavenging the upper. The tool may be used, for the extraction of piles by causing the blow to be struck in the upward direction, the pile being attached to lugs 23, and the downward blow prevented by altering the relative position of the trip 13a by the introduction of a distance piece between the plate 15 and the ram 1. A double acting hammer may be converted to single action by the use of a manually controlled relief valve in the lower end of the piston.

Title: Inverter arrangements for d.c. to a.c. conversion
IPC: H02M7/538
Filed: 1962-06-29
Abstract: 1,019,085. Inverting. VILLAMOSIPARI KUTATO INTEZET. June 29, 1962 [July 6, 1961], No. 25148/62. Heading H2F. A transistor inverting arrangement of the type having an oscillator driving an inverter, has another transistor connected in series with the supply to either the oscillator or the inverter or an intermediate amplifying stage if one is used, and this transistor is controlled by the difference of two voltages, one derived from the D.C. source and the other derived from the output. The battery 1 (Fig. 1, not shown) supplies the oscillator 2 and the inverter 3. The oscillator supply circuit includes the transistor 10, and the oscillator input voltage is stabilized by the Zener diode 5. The transistor 10 is controlled by the voltage drop across the resistance 6, which depends on the D.C. source 1, and a voltage derived from the output 4 through the transformer 7, rectifier 8 and potential divider 9. To start the circuit push-button 14 is pressed and the transistor 10 made conducting while the capacitor 12 charges through the resistance 11. Diode 15 prevents the capacitor 12 being charged through the resistance 9. In normal operation transistor 10 conducts, but if the output voltage falls below a certain value (which may be adjusted by the divider 9) the transistor switches off and the oscillator 2 stops. Other embodiments have the transistor 10 in series with an intermediate amplifying stage (Fig. 2, not shown) in which case the oscillator continues to operate when the inverter is stopped, a filter or polyphase rectifying arrangement in place of the rectifier 8 of Fig. 1 (Figs. 3 and 4, not shown) or the transistor 10 connected between the positive D.C. line and the amplifier (Fig. 5, not shown).

Title: Improvements in or relating to directional antenna systems for electromagnetic wave-energy
IPC: H01Q3/18
Filed: 1948-09-27
Abstract: 658,769. Aerials. SPERRY CORPORATION. Sept. 27, 1948, No. 25163. Convention date, Dec. 3, 1947. [Class 40 (vii)] In a directional antenna system comprising a dipole 1 and a parabolic reflector 4, scanning is effected by relative rotation of two cupshaped dielectric refracting members 7 and 8 having walls of progressively varying thickness with thinnest and thickest parts at opposite ends of a diameter. A disc-type reflector 5 is supported in front of the dipole 1 to effect rearward deflection of forwardly directed energy. The two refracting members 7 and 8 are rotatable respectively by reversible variable speed motors 13 and 15 by means of geared hollow shafts 9 and 10 carried in the bearing 11. A rigid transmission line 2 passes to the dipole 1 through the hollow centre of shaft 9. With the members 7 and 8 in the relative positions shown in Fig. 1 the directive axis of the antenna is uneffected and when the two thickest parts of the members are adjacent, as in Fig. 1a (not shown), the axis undergoes maximum deflection. By varying the relative speeds and directions of rotation of the memo bers 7 and 8 scanning of any desired form may be obtained such as the spiral or petal patterns indicated in Fig. 3 (not shown). In order that the sector being scanned may be varied the whole assembly may be mounted for movement about vertical and horizontal axes as in Fig. 2 (not shown). To dynamically balance the rotating members 7 and 8 small counter weights 42 and 42<SP>1</SP> may be attached at their thin edges. An alternative embodiment, Fig. 4 (not shown), comprises a wave-guide horn and metal beam-forming lens with cup-shaped refracting members rotatable between the two. Instead of the dielectric cup-shaped wedge metal refracting devices may be employed. The Specification as open to inspection under Sect. 91 comprises also an embodiment having only one cup-shaped refractor to produce only conical scanning Fig. 2 (Cancelled, not shown). This subject-matter does not appear in the Specification as accepted.
