Title: Brushless dc electric motors
IPC: H02K29/00
Filed: 1970-06-09
Abstract: 1323342 Electric motors; inverting AGENCE NATIONALE POUR LA VALORISATION DE LA RECHERCHE 9 June 1970 [10 June 1969] 27726/70 Headings H2A and H2F In a brushless D.C. motor, the iron rotor 25 is bell-shaped and carries a series of permanent magnets A 1  ... A 8  on its inner surface which co-operate with main winding B 1 B<SP>1</SP> 1  ... B 3 B<SP>1</SP> 3  mounted circumferentially on the stator core Fe. A flat magnet A 9  on the base of the bell, Figs. 4 and 5 (not shown), provides 4 pole pairs which co-operate with windings (b 1 , b<SP>1</SP> 1  ... b 3 , b<SP>1</SP> 3 ) on the end face of the stator core to control electronic switching devices supplying current to the main windings. The ring Fe may be of non-ferromagnetic plastics material. The motor may be used as a pilot motor in a D.C.-A.C. converter employing a transistor bridge T 1 -T<SP>1</SP> 3 , Fig. 6. The motor m drives a position sensor CT which may be an inductive pick-up of the type depicted in Figs. 4 and 5. The output frequency may be varied by altering the speed of the pilot motor. In a constant frequency converter, Fig. 7 (not shown), the transistors are triggered by the output signal of a synchro driven by the pilot motor whose speed is stabilized by a tuning fork oscillator. The output phase sequence may be reversed by reversing the pilot motor or by altering the output of the sensor CT.

Title: Wagon retarders
IPC: B61K7/06
Filed: 1969-09-12
Abstract: 1328086 Track brakes; hydraulic buffers DOWTY MINING EQUIPMENT Ltd 11 Sept 1970 [12 Sept 1969] 45107/69 Headings F2E and F2S [Also in Division B7] A wagon retarder for installation on a rail 10 comprises an hydraulic cylinder 14 slidable in an upright guide cylinder 11 and having a domed head 15 which is engageable by the flange of a wagon wheel rolling on the rail to tend to cause telescopic contraction of the cylinder 14 and a rod 16 which extends sealingly through one end thereof: a piston 19 integral with the rod 16 divides the cylinder 14 into two chambers 21 and 23 both containing hydraulic fluid and the piston 19 includes valve means 24, 25 and 29, 30 whereby hydraulic fluid flows from chamber 21 to chamber 23 during telescopic contraction of the cylinder 14 and the rod 16 but which valve means is also actuable to generate pressure in chamber 21 to resist downward movement of the cylinder 14 and cause a retarding force to be exerted on the wheel, there being a volume of compressed gas at the top of the cylinder 14 to cause telescopic extension of the cylinder 14 and the rod 16 when the wheel rolls away. As shown, the valve means comprises a spring loaded pressure-sensitive valve member 25 and at wheel speeds below a predetermined value the fluid flow from chamber 21 to chamber 23 will be insufficient to close holes 24 with member 25 and telescopic contraction of rod 16 and cylinder 14 will take place so that no retarding force is exerted on the wheel. However at speeds above the predetermined value the holes 24 will be closed, and fluid can only flow through a relief valve 28, 29 via holes 27, this will cause apressure to be set up in chamber 21 and a retarding force will be exerted on the wheel. The springs 26 may be discarded so that the retarder acts at all speeds. The fluid returns to chamber 21 via a damping valve which comprises a clack plate 31 which acts to partially close holes 24 during return flow. The compressed gas above the level 22 in chamber 21 besides acting to re. turn the cylinder 14 to its initial position also cushion the initial impact of the wagon wheel on the retarder. This gas is introduced into chamber 21 through a hole 41 before a sealing screw plug is fitted into the cylinder bore 18.

Abstract: 1349244 Packaging cigarettes HAUNTWERKE KORBER & CO KG 19 April 1971 [29 Oct 1969] 41336/70 Divided out of 1349243 Heading B8C The description is identical with that with reference to Figs. 1-14 of Specification 1,349,243, but the claims are directed to a method for packing articles in which wrapper components and articles to be packed are conveyed cyclically and packing operations are performed during work cycles which consist in each case of a feed step and a stoppage phase and in which, after emission of a signal at any point in time to interrupt the packing operations, a work cycle which has already been commenced, is carried onward to the end of critical packing operations. The claims are also directed to a packing machine for carrying out the method. The description also includes a modification Figs. 15a-15d and 16a-16c of the machine according to Figs. 4a-4d of Specification 1,349,243. As shown, Figs. 15a-15d, tin foil blanks 2086 and paper blanks 2132 are supplied at points B<SP>1</SP>2 and B<SP>11</SP>2 to a finishing turret 2042 which forms part of a packing track Y2, prepared empty packets 2041 being transferred at a point B2 to a packing turret 2179. An additional gumming device 2291 is provided for gumming the open second bottom flap of an empty packet 2041 after the folding operation of the folder 2173 for folding one flap, and a supervisory control unit 2222 replaces the unit 222 of Figs. 4a- 4d. In operation, a wrapper feeder 2131 supplies and transfers a paper blank 2132 at the point B<SP>11</SP>2 where the blank is folded around a tin foil blank 2071 and bottom tucks are folded in by a folder 2127 as described for Figs. 4 and 13 these operations being controlled by the unit 2222 in dependence upon the supply of cigarette blocks 2008 to the feed path U2. The empty packet is completed as described for Figs. 4 and 13. At a transfer point B2, the finished packet is transferred by a transfer device 2175 into a holder 2178 of turret 2179 and at an assembly point C2 the block 2008 which initiated the feed of the blanks 2071 and 2132 is assembled into the packet 2041, by the means described with reference to Figs. 4 and 13. If the machine is stopped at any point in time which is critical for one or more of the packing operations, such as gumming, folding or transfer of blocks 2008 between turrets, the machine can only come to a standstill at the end of one work cycle at which all critical operations are completed. The additional gumming device 2291 ensures that gumming of one surface is completed during one cycle. The machine is controlled by electropneumatic circuitry which is described in detail with reference to Figs. 16a-16c (not shown). Specification 1,349,251 is referred to.

A motor reciprocates or oscillates the members substantially at a common natural frequency. The members may be an inner cutter member 1 and a pair of counterweights 9, the member 1 being borne by a block 2 on a bridge member 3 supported by outer spring arms 4, 5, Fig. 3, of a resilient member 6, a central arm 7 being fixed to a part 8 of the shaver body, while a lower part 11 is supported between resilient blocks 12. The weights 9 are borne similarly by a second bridge 3a attached to a resilient member 6a, supported between the part 8 and further resilient blocks 12a. Eccentric cams 23, 23a on a shaft 21 of the motor 19 are located in apertures 22, 22a of the bridges 3, 3a for effecting reciprocation of the members 1, 9, and flanges 17, 18, along with the general shape and elasticity of the members 1, 9, achieve the required reciprocation. Alternatively, Figs. 7 and 9, the inner cutter 1b may be supported by lugs 12b on bridges 10b between outer arms 9b of resilient members 6b attached to fixed parts 8b, the counterweight being borne on a bridge 16b between inner arms 9b of the members 6b. Respective pins 19b, 21b attached to the members 16b, 10b may be driven through connecting rods 20b, 22b by a crankshaft 18b of the motor 17b. The shaft 18b may also oscillate a rod (24b), Fig. 8 (not shown), for driving a long hair cutter. Further, Figs. 10, 11, two parallel inner cutter blocks 4c, spring urged apart by springs 10c, may be oppositely reciprocated by means of peg connections 18c to a disc 16c arranged to be oscillated under the control of springs 20c by an eccentric pin 14c of a motor-driven disc 13c, the blocks 4c sliding on rods 7c. Also, Fig. 14, two cutter sections lbd, lad may be supported on bridge members 10d for opposite reciprocation (c.f. Fig. 7), or parallel inner cutter blocks (4e), Fig. 16 (not shown), may be attached respectively to a coaxial coil (12e) and permanent magnet (15e) of a linear electric motor for opposed reciprocation. The invention is applicable to a razor in which two co-operating cutter heads are driven in antiphase to provide a shearing action. Again, an angularly oscillating foil may be split into two portions operating in antiphase and cooperate with an arcuate foil. A single cutter and counterweight may so oscillate.
