Title: Improvements for lifting jacks
IPC: B66F1/02
Filed: 1937-10-21
Abstract: 501,554. Lifting-jacks. BOWMAN, G., and SMITH & SONS (MOTOR ACCESSORIES), Ltd., S. Oct. 21, 1937, No. 28770. [Class 78 (iii)] Friction - ratchet lifting- jacks in which upper and lower friction members slide on a column and bind thereon when tilted, the upper member comprising a load-receiving abutment offset from the column and the lower member forming an abutment for the operating lever, are fitted with a bracket sliding on the column and coupling the two friction members together in spaced relationship. Fig. 1 shows an upper friction member 13 which bears against a collar 32 on a sliding load-supporting member. The latter may be adapted to tit into a bracket 34 fixed on the framework of a motor vehicle. The lower friction member 14 is connected to the coupling bracket 15 by a spring 24 and the lever 28 connects the bracket to the member 13. The operating lever 16 is pivoted to the bracket 15 and linked to the friction member 14. Depression of the lever 16 first causes the member 14 to tilt and bind on the standard 10 and then raises the bracket 15 bodily, thus causing the collar 26 to raise the upper member 14 and the load. On raising the lever 16, the member 14 tilts and supports the load, and the spring 24 raises the member 14 to the new position of bracket 15 ready for another stroke. Depression of the lever 28 rocks the member 13 into its non-gripping position and permits lowering. A ball-mounted foot 12 is fitted to the column. Fig. 2 shows a construction in which the coupling bracket encloses the two friction members 41, 47. Raising of the lever 50 causes the member 47 to tilt and grip and then raises casing 40 bodily and the load carried in the crutch 43. On lowering the lever, member 41 tilts and grips and the spring 49 restores 47 ready for another stroke. Depression of 44 tilts member 41 into non-gripping position for lowering.

Title: Method of reducing disturbing currents induced in signalling lines by neighbouring power lines
IPC: H04L25/08
Filed: 1924-12-04
Abstract: 225,861. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Dec. 4, 1923, [Convention date]. Preventing induction.-Relates to the reduction of disturbing currents due to neighbouring power lines. The power line Jo induces in the line wires currents ia, ib, which give rise to a resultant disturbing current ia-ib in the line circuit I. If a phantom circuit is formed, further currents i'a, i<1>b are induced in the line wires, giving rise to a resultant current i<1>a-i<1>b in the circuit I. The invention consists in tapping the end transformer R in such a way that these resultant currents neutralize each other. The phase differences may be lessened by capacity or impedance shunts across the line. This methcd may be applied to the whole line or sections thereof. One such phantom circuit line may be employed as a compensation conductor for neighbouring lines.

Title: Electrically-powered blind riveting hand tool
IPC: B21J15/26
Filed: 1965-07-12
Abstract: 1,089,733. Blind riveting. GESELLSCHAFT FUR INTERNATIONALE PATENTVERWERTUNG m.b.H. July 12, 1965 [July 14, 1964], No. 29392/65. Heading B3U. An electrically operated hand tool for setting blind rivets comprises an electric motor 13 driving a spur reduction gear 16 and a worm and wheel 18 and 21. Mounted on the shaft of the wheel 21 is a pinion 11 which meshes with a mutilated gear-wheel 5. A rod 8 connects an eccentric pin on the wheel 5 with a chuck of known type which grips the rivet mandrel. Rotation of the wheel 5 pulls the chuck to set the rivet and break-off the mandrel, on the forward movement of the chuck, the jaws open and the rivet shank is ejected. Secured to the shaft of the wheel 5 is a slotted disc 7 which is engaged by a pin 20 on a member 12 connected to a trigger 13. A tension spring 19 tends to rotate the wheel 5. The motor is started by a switch 25 and when the trigger 13 is operated the wheel 5 rotates due to the spring 19 until it meshes with the pinion 11 and is then driven until the gap in the teeth is again opposite the pinion and rotation is stopped by the pin 20. In an alternative mode of operation the switch 25 remains in the " off" position, the rivet mandrel is inserted in the chuck and the trigger 13 is actuated to release the gear-wheel 5. The small rotary movement of the wheel, due to the spring 19 causes the chuck jaws to grip the mandrel so that the rivet assembly will not fall out of the tool while it is being inserted in the work. Further pressure on the trigger 13 then operates the switch 15 to start the motor and set the rivet. In a modification, the gearwheel 5 may be replaced by a mutilated wormwheel driven by a worm.

Filed: 1946-10-03
Abstract: 662,431. Woodbending. STANDARD TELEPHONES & CABLES, Ltd. Sept. 26, 1947 [Oct. 3, 1946], No. 29539/46. Class 145 (ii) [Also in Groups VIII and XI] Pressure apparatus for forming and shaping materials (e.g. plywood, veneer) comprises a non- rigid articulated platen A<SP>1</SP>..A<SP>5</SP> adapted to distribute pressure applied directly thereto uniformly over a work-piece L; whereby the latter can be forced to change its shape with conformity with an opposed rigid platen M<SP>1</SP>. The platens are preferably of metal (e.g. steel or phosphor-bronze) and adapted for heating the work, the zone A<SP>5</SP> in the example shown being fully flexible thus providing a continuous articulated upper platen working on the hinge principle. The platens may be the electrodes of a high frequency dielectric heating apparatus. Pressure is applied uniformly to the upper platen through systems of loosely linked pressure distributing members such as B<SP>1</SP>, P<SP>3</SP>, H<SP>5</SP>; B<SP>2</SP>, Q<SP>2</SP>, p<SP>4</SP> H<SP>7</SP>; by means of screws S<SP>1</SP>, S<SP>2</SP> mounted in the framework R, the pressure screw S<SP>2</SP> working in a guide rail F and being freely pivoted in the part T<SP>1</SP>.

Screw S<SP>2</SP> is then moved to the right in the guiderail F to force the material downwardly, the screw finally being rammed home to straighten the link C and give the material the shape shown. Stiffening ribs N<SP>1</SP> ... N<SP>7</SP> may be provided across the upper platens and between the members H, whilst both platens may be curved in a plane at right angles to that of the Figure.
Patent GB-629462-A (GB)
Title: Improvements in or relating to gyroscopes
IPC: G01C19/42
Filed: 1947-11-05
Abstract: 629,462. Gyroscopic apparatus. HARLE, T. F. Nov. 5, 1947, No. 29552. [Class 97 (iii)] In a rate of turn gyro the disturbing torques exerted by the gyro rotor on the single gimbal ring about its axis as a result of angular movement of the frame about an axis parallel to the undeflected position of the spin axis when the rotor and gimbal ring are deflected is opposed, for small deflections at least, by torque derived from or controlled by means responsive to acceleration of the frame in a direction normal to the plane defined by the gimbal axis and the undeflected spin axis. As shown in Fig. 2, the gimbal ring 12 by means of which the rotor 11 is mounted in the frame 13 is provided with the usual spring restraint 14 and has secured at one of its ends a camplate 15 with part circular faces 16 and an intermediate flat portion 17. A cam follower 18 and a mass 19 are mounted on the base member 20 of a U-shaped frame, Fig. 1, whose side members 21 extend rearwardly to pivots 22 on the opposite upright of the frame 13, the pivots having an axis substantially parallel with that of the undeflected spin axis. A coiled tension spring 23 supports the frame 20 with the roller 18 and mass 19 so that, in the absence of accelerations, the roller 18 applies virtually no pressure to the cam 15 and hence no torque to the gimbal 12 when the gyro is undeflected and only very little torque when it is deflected within the limits of face 17. Owing to the circular form of the cam, pressure of the roller 18 against the faces 16, 16 produces no torque on the gimbal 12. When, however, the gimbal is deflected. and acceleration in a direction normal to the plane defined by the gimbal axis and the undeflected position of the spin axis is present, so that the roller 18 is displaced along the operative part 17 of the cam 15 such upward acceleration will, by the reaction on the mass 19, result in an increased pressure by the roller 18 so as to apply a torque about the axis of the gimbal 12. The direction of spin of the gyro is so arranged that this applied torque compensates that arising from the gyroscopic effect caused by acceleration of the frame 13 with the gyro spin axis in a deflected position. The cam may be grooved so as to compensate similarly for downward accelerations, or the torque may be applied pneumatically, hydraulically or electrically in response to a movement of an accelerometer, a cut-out being provided so that compensating torque is cut-off when the spin axis deflection exceeds a predetermined value, or when there is no deflection.
