Abstract: 1,083,670. Feeding documents. NATIONAL CASH REGISTER CO. Dec. 17, 1965 [Jan. 18, 1965], No. 53613/65. Heading B8S. Documents 74 are discharged oneby-one from the bottom of hopper 75 by the reciprocation of knife carrier 19 operated by bell-crank 9 pivoted at 13 and actuated by follower roller 15 and cam 51. Carrier 19 is pivoted at 20 to said bell-crank 9 and is spring-pressed at 30 against lifting link 34 which is pivoted at 35, articulated at 36, impelled by cam 47 and roller 42, and controlled by bell-crank 63. Bell-crank 63 is operated by solenoid 65, the armature 66 being pivoted at 68. Additionally bell-crank 9 is biased by spring 60 secured at 61 to links 55, 56, pivoted at 58. Operation.-Normally knife carrier 19 does not engage link 34 and therefore reciprocates horizontally beneath hopper 75 without discharging the documents. When, however, solenoid 65 is actuated, bell-crank 63 is moved to the position shown and constitutes a pivot for the link 34. The movement of cam 47 is now transmitted as an up and down movement of link 34 bending between fixed pivots 35 and 39a, by roller 42. Thus carrier 19 is raised at the commencement of a stroke and is lowered at the end of the stroke so that the documents 74 are fed forward to discharge rollers 82, 83 singly from the bottom of the stack. The action of cam 52 complements the action of cam 51 so that rollers 15 and 42 follow closely the cam surfaces 51 and 47.

Abstract: 1,091,339. Separation of monomers and oligomers from high polymers. VICKERSZIMMER PLANUNG UND BAU VON INDUSTRIEANLAGEN A.G. Dec. 20, 1965 [Dec. 23, 1964], No. 53829/65. Heading B1B. Vaporisable components of low molecular weight are separated from high polymer compounds by vacuum distillation in a vessel 2 which is under the action of two steam jet ejectors 8 which are maintained at such a temperature as to prevent condensation occuring within the ejectors, the vapours formed together with the steam from the ejectors being condensed as an aqueous solution of the low molecular weight components in a water-cooled condenser 12. The jet ejectors are maintained at a temperature of 200C to 280C by either a steam-charged heating jacket which also surrounds pipe 7 or by feeding in superheated steam, the vapours being compressed to about 25 Torr by the ejectors whereby a pressure of about 2 Torr is maintained in the vessel 2. The propulsion seam is adjusted so that 15 weight units of steam are consumed per weight unit of extracted vapours. The polymerisation product requiring separation and entering through line 1, e.g. polymerised caprolactam or a polycondensate of ethylene glycol-terephthalate, is distributed over the surface of the vessel 2 as a thin film.

Title: Self aligning weighting element assembly
IPC: D01H5/46
Filed: 1976-12-24
Abstract: The load arm (A) carries two driven rollers (RR, R') at one end and at its other end is supported on the housing (B, O), for example via a knife-edge mounting, in such a way that it is spherically pendulous about this point of articulation (O). The load arm is thus pivotable about a vertical axis, about a longitudinal axis and about a transverse axis. The load arm (A) is pressed via its rollers (R, R') against a drive body (D) by means of spring force (S). The free movability of the load arm (A) has hitherto been adversely influenced by this pressure force (S). In order to avoid this, a rolling body (K) is arranged between the pressure spring (S) and the load arm. The disturbing influence caused by spring deflection is prevented by this rolling body (K). The rolling body (K) is located in a U-shaped cap (HB) which is supported on the spring (S). The rolling body (K) rolls on the cap and on the load arm. <IMAGE>

Title: Toroidally Wound Disc Armatures
IPC: H02K15/08
Filed: 1966-12-06
Abstract: 1,153,780. Making disc armatures; winding toroidal helices. CIRCUIT RESEARCH CO. 6 Dec., 1966 [9 May, 1966], No. 54537/66. Headings B3A and B3E. [Also in Division H2] A method of making an armature for a disctype dynamo-electrical machine having a multipole stator comprises mounting an annular mandrel 40 for controlled rotation about its axis; toroidally winding insulated wire about the mandrel; controlling the angular speed of the toroidal winding and the angular speed of the mandrel in such a way that the winding is distributed substantially uniformly over the surface of the mandrel; and connecting the ends of the winding together. The winding is formed about a flat annular mandrel 40 blanked from a sheet of heat deformable plastic and it has notched inner and outer edges 41, 42 respectively, the latter of which engage in a drive gear 43. A length of wire is placed on a bobbin 45 and one end is attached to the mandrel, thereafter both are rotated counter-clockwise and in the case of an eight-pole machine the bobbin completes approximately four revolutions to one of the armature. The actual ratio is selected so that when the bobbin has completed four revolutions the mandrel is one notch short of a complete revolution. The wound mandrel is clamped on a cylindrical jig 52 and rings 53, 54 are fitted on either side of it. The rings are fitted with pins 55, 56 which locate between the wires when in contact with the mandrel and rotation of the rings in opposite directions forms the windings into the shape shown in Fig. 2. A slot 49 is provided at the apex of each outer notch, each slot ending in an aperture having a diameter approximately equal to that of the wire and the wires are pulled into the apertures as they are shaped, Fig. 5A (not shown). The rings are heated and apply pressure to the mandrel so as to embed the wires thereinto. In an alternative method, the mandrel itself is fitted with pins which guide the wires to shape during winding. The wires are secured by compressing the wound mandrel between heated plates. In a further method a doughnut-shaped mandrel is used, this being highly compressible but having exterior surfaces resistant to deformation. The surface may be either plain or grooved to guide the winding into the required position. After winding the mandrel is placed between heated platens which form it into a disc-like form. Where the conductors are sufficiently heavy or where a separate dielectric support disc is included within the mandrel, the plastics material may be dissolved out after the armature has been crushed into shape. The method of the invention is suitable for either wave or lap wound armatures.
