Abstract: 441,280. Garage lifts. MARX, J., 13, Zulpicherstrasse, Duren, Rhineland, Germany. July 16, 1934, No. 20780. [Class 78 (iii)] Comprises arrangements of tackle and platform-guiding means in the type of car lift in which a guided platform is raised and lowered on four posts by means of tackles. The Figure shows the platform provided with carreceiving members 4 and guided in the slotted, hollow, box-shaped pedestals by means of superposed rollers 8, 9 bearing against the front and rear surfaces of the pedestals. The rollers may be replaced by long sliding guide shoes. Both front and rear of the platform are provided with a pair of tackle chains or ropes 13 and 14. Chain 13 passes from the fixed point 20 round the pulleys or sprockets 19, 18, and both pulleys 17 at opposite ends of the platform to a sprocket wheel 15 on the shaft 16, thus having three falls on the lefthand side of the platform and one on the righthand side. The other chain 14 passes from another sprocket 15 on the same shaft round the pulleys 21, 22, and both pulleys 8 to the fixed point 24, thus having three falls on the right-hand side and one on the left-hand side of the platform, making a total of four falls of both chains on each side of the platform. By operating the shaft 16 through worm and chain gearing from a motor 30, the platform is raised or lowered; the superfluous chain being received into or payed out from compartmented boxes 32. The pedestals are mounted on or fixed to feet 2 provided with levelling screws. The two shafts 16 at the front and rear of the appliance are coupled by a universally-jointed shaft. The chains may extend under the platform from front to rear instead of from side to side. Pins inserted in holes 34 may fix the platform at any desired height.

Title: Improvements in or relating to direct current power supply arrangements including static convertors
Inventor: NYE ROGER SYDNEY
IPC: H02M3/338
Filed: 1968-05-02
Abstract: 1,273,525. Static converters. GENERAL ELECTRIC CO., Ltd. 1 Aug., 1969 [2 May, 1968], No. 20816/68. Heading H2F. In a DC/AC/DC converter comprising an inverter stage 1 (Fig. 1) connected to an unstabilized DC source 2 and rectifier 3 the output of which is fed via a current or voltage stabilizer 4 to a load on terminals 5, 6, there is provided at least one toggle circuit 17 which produces an output signal to an OR gate 20 at inputs 21 in the event of a fault condition, the OR gate 20 sending a signal via an amplifier 23 to suspend operation of the inverter. Thus there may be one toggle circuit to respond to overvoltage at the stabilizer output, one responsive to undervoltage and one responsive to overcurrent and so on. The toggle circuits may also actuate fault indicating lamps 33. The setting of one toggle under fault conditions inhibits the setting of the others. In the overvoltage responsive arrangement shown in Fig. 1, when the output voltage of the converter arrangement exceeds a predetermined limit a zener diode 12 ''breaks over" and turns off a normally conducting transistor 13. This sets the toggle circuit so that transistors 18, 19 therein conduct and a resulting output from the collector of 19 to the respective OR gate input 21 produces an output from gate 20 and amplifier 23 to bias off bridge connected transistors in the inverter 1. An overcurrent sensing arrangement is described with reference to Fig. 3 (not shown). There may be more than one stabilizer connected to the rectifier output. The inverter comprises bridge connected transistors and is transformer coupled to the rectifier which comprises diodes connected in a bi-phase arrangement (Fig 2 not shown).

Abstract: 300,302. Lloyd, G. E. Aug. 10, 1927. Springs, arrangement of; guiding vertical play.-In arrangements in which an axle bracket 3 supports the vehicle frame by springs 4, 5 and is further constrained to move in a vertical plane by a link connection at its front end, the rear or both ends of the bracket may be guided vertically by slippers sliding over guide bars on the frame with the object of introducing friction to damp vertical movements. The. axle 2 is carried by an axle bracket 3 which supports the vehicle frame by four helical springs 4 and a stiffer buffer spring 5. The forward end of the bracket 3 is pivoted to a rigid lever 14 which is also connected by pin joints 15 to sleeves 12 slidable on a tube 7. The rear end of the member 3 is similarly pivoted to two links 18 each pivoted to vertically slidable sleeves 12. This arrangement permits tilting as well as vertical play of the member 3. The tubes 7 are fixed to the vehicle frame at their upper ends and are stayed at their lower ends by a rod 8 and by inclined longitudinal and transverse rods 10, 11. The lateral displacement of the wheel tread as regards the tubes 7 results in laterial pressures between the tubes and the sleeves which create friction for damping. The sleeves may be split, as shown in Fig. 4 and closed on to the tubes 7 by springs 19 for the same purpose. The tubes may be replaced by a number of flat guide bars separated by slipper plates, the whole being pressed together by springs.

Title: Improvements in or connected with machines for wrapping cigars and other elongated bodies
IPC: B65B19/26
Filed: 1927-08-16
Abstract: 298,730. Forgrove Machinery Co., Ltd., and Grover, F. Aug. 16, 1927. Packeting by wrapping-up.-Relates to machines for wrapping cylindrical objects with conical or like ends such as cigars. The cigar B, Fig. 2, is placed by hand or fed by any suitable means on to a plunger C, which rises with it and a wrapper B<1> into the position shown in full lines. During the ascent, side folders A<2> turn the wrapper down about the cigar into an inverted U-shape, and the assembled cigar and wrapper is seized by spring grippers D on a rotary turret (not shown). A movable blade E turns up one depending edge of the wrapper beneath the cigar, and the rotation of the turret causes a fixed plate F to turn up the other edge before arriving at the second position of rest. At this position, the partially wrapped cigar comes beneath forked members G shown in plan in Fig. 7, and above a die or tucking piece J, shown in elevation and plan respectively in Figs. 8 and 9. Each fork has a gap G<8> coinciding approximately with the end of the wrapper. The forks descend and the die ascends so that the projecting ends of the wrapper are formed into a pleat, as shown in Figs. 14, 15. with side ears B<2>, B<3> caused by projections J<1> on the die passing up between the gaps G<8>. The edges J<2> on the tucking piece J are arranged in V-shaped formation, and cause the pleats in the portions of the wrapper which do not extend beyond the cigar to lie snugly against the ends of the cigar as shown in Fig. 16. the ends of the cigar being supported in the ends of the die while this folding takes place. Fingers H, pivoted on the forks G, are turned in by the continued descent of the latter to fold in the depending side ears B<2>, so that an end view of the cigar is as shown in Fig. 18. The other ears B<3> are turned up by passing over raised portions H<4> of the forks when the grippers D carry the packet to the next position of rest. The ends of the cigar are now completely enveloped, with tabs B<4>, Fig. 20, resulting from the folding up of the ears B<2> B<3>, projecting from each end. At the next position of rest, the tabs B<4>, which have been supported during the travel of the turret by passing between fixed blades, arrive above blades M, Fig. 4, on vertically movable rods M<1>. The grippers D are released and the cigar is supported by the blades M while forked pieces N, associated with pressing fingers N<2> on spring supports N<3>, descend with the blades M until the cigar rests on a support O. During the continued descent of the fingers N<2>, they first turn down the tabs B<4> over the blades M as shown in Fig. 25, and finally, after the withdrawal of the blades M, press in the downturned tab as shown in Fig. 27. The wrapped cigar is then discharged from the machine. Specification 277,753 is referred to.

Filed: 1927-08-17
Abstract: 298,732. Angold, H. E., and Smith Meters, Ltd. Aug. 17, 1927. Induction motor meters.-The magnetic iron system is so arranged that the path of the potential flux lies wholly through the disc and include the series cores, and a large proportion of the potential flux is used for torque purposes. The magnetic iron circuit is built up from stampings shaped as shown in Fig. 1, in which a closed loop is provided with projections a, on which the series coils are wound, and a projection b opposite the projections a and with its lower edge substantially covering the adjacent edges of the projections a, with an intervening gap e in which the disc 12, Fig. 3, rotates. The stampings are clamped between end plates by bolts and screws 7, Fig. 3, passing through certain of the holes l in the stampings and the whole is secured to bosses on the base 1 by screws 8 passing through the remaining holes l. In order to provide for a proportional falling-off of torque with increase of potential, a stamping of the shape shown in Fig. 2 is provided. This is in the form of a loop similar to the main stampings, without pole-piece projections but with a transverse strip g forming a restricted iron path for some of the potential flux. The effective area of the strip g may be reduced by slotting or otherwise. A downwardly dependent part h is fixed to the potential core with good magnetic connection, and the strip g in conjunction with a bracket 35, Fig. 3, holds the potential coil 11 in place. The strip g readily becomes saturated, so that the increase of flux cutting the disc is proportionately greater than increase of voltage. Most of the flux from the potential coil 11 passes through the disc 12 in two parallel paths to the pole-pieces a, returning by the side yokes, as shown by the arrows c, Fig. 1. The flux due to the series coils follows the path d, and interacts with the potential flux toproduce a driving- torque. The series cores may have an interpole to pass a small part of the potential flux through the disc by an intermediate path without deflection by the series flux. The potential coil is slipped over the core b by bending aside the lower portions of the stampings. The formerwound series coils are slipped over the cores a and the stampings bent back to their ordinal form. Surrounding the pole of the potential core in a closed copper loop 29, Fig. 3, carried by a bracket 25, which is adjustable vertically by screws 28 and slotted lugs 27 for quadrature adjustment. No-load correction is effected by lateral movement of the loop 29 by means of a screw 34. The bracket 25 may alternatively form a complete loop for quadrature adjustment.
