Title: Improvements in phonograph pick-up devices
Inventor: ARENTZEN HOLGER CHRISTIAN
IPC: H04R9/12
Filed: 1950-02-10
Abstract: 690,490. Gramophone pick-ups. FONOFILM INDUSTRI AKTIESELSKAB. Feb. 10, 1950, No. 3504/50. Class 40 (iv). In a moving-coil pick-up for lateral cut records, rotational movement is imparted to an elongated armature 1 carrying a longitudinal winding 2 by a radially extending stylus arm 8 which yields to axially directed pressure. The armature ends have slots 5 to receive the winding and are secured to extension members 1a, 1b which engage sleeves 6 of an elastic and damping material carried by a non-magnetic holder 4. The stylus arm is attached to the extension member 1a and carries a stylus 9 which has its tip situated in the plane of an inclined intermediate arm section, while highfrequency damping is provided by a pad consisting of a mass 15 interposed between layers 14, 16 of a damping material such as artificial rubber. The holder 4 forms part of a fixed structure comprising a permanent magnet 12 with polepieces 3 and an outer casing 10, and carries a lower cover 7. The sleeves 6 provide an armature-controlling force which is so selected in relation to the moment of inertia of the fixed structure that the resonance frequency of the latter lies between the lowest recorded frequency and the rotational frequency of the record. In a modification the extension members may be omitted and direct contact made between the slotted armature ends and the sleeves 6. If necessary, the armature-controlling force may be reduced by omitting one sleeve, preferably the lower one. Specification 651,757 is referred to.

[Also in Group XXXIV] In a bearing construction for a machine having a vertical assembly of rollers 1, 3 of which one 2 is laterally withdrawable, each trunnion of the roller 2 is mounted in a roller bearing 5 carried by a bearing block 6 of generally square form, which in turn is supported by an axially movable member 9 carried by the machine frame 11 to facilitate removal of the roller 2. The member 9 has a vertical portion 10 having an opening 8, Fig. 6, for the reception of the bearing block 6, and the upper surface has guideways 13 which engage complemental guideways 15, Fig. 3, formed on the base of a bearing block 16 for the bowl 3. A screw 27 mounted in a bracket 26 secured to the end wall of the member 9 engages a nut 21' disposed in a circular hole 20 in the base of the block 16. Rotation of the screw 27 causes relative axial displacement of the members 9, 16. A lifting screw 23 is pivoted to the top of the block 16, whereby the block 16 and member 9 may be raised to enable the bottom portion of the member 9 to clear the part 11a of the frame 11 so that on rotation of the screw 27, the block 9 may be moved axially out of engagement with the bearing block 6 to effect lateral withdrawal of the roller 2. Vertical guides 14 are provided on the member 9 for engagement with the frame 11. The invention is applied to a photogravure printing machine.

Convention date, Feb. 5, 1932. Addition to 341,786 [Class 40 (v).] In a super-regenerative receiver bhe energy feed-back is through a Wheatstone bridge arrangement and means are provided to unbalance the bridge in opposite directions so that the feed-back is changed in phase such as to give re-generation for one direction and degeneration in the other direction. The bridge may be unbalanced by applying the interruption frequency to vary the flux density of iron cored chokes in the bridge arms (Fig. 2 not shown) or by varying capacities forming two of the bridge arms by mechanical means (Figs. 3, 3a not shown). Fig. 4 shows an arrangement in which the feed back of the coil T to the circuit LC is controlled from a source Fi acting on a bridge comprising the two halves of the coil T and condensers 9 9<1> the latter being the input capacity of valve 2<1> which is varied by variation of the resistance of the valve 2<11>, in the plate circuit. Alternatively the coil T may be arranged as one diagonal of a bridge Fig. 5 or may be centre tapped and itself form two arms of the bridge (Fig. 6, not shown). Two of the bridge arms may comprise condensers (Fig. 7 not shown) and the self capacities of the valve used are compensated for in the adjacent bridge arm. The bridge arrangement and the associated coupling coil may be arranged in the input of the valve instead of in the output as shown.

In a modification, (Figs. 3 and 4, not shown), the pole-wheel consists of radial magnetic spokes 27, between which are flat magnets 27 and the poles 26 of the other polarity. These poles are secured by a dovetail arrangement at each end, and are axially extended to a magnetic ring 34 by which the flux is shunted to the casing under control by coils 37, 38. Alternate poles, spaced by magnets, or by a shaped magnetic body, may be integral with hubs on opposite sides of the rotor, these hubs serving as the shunts (Figs. 5, 6 and 7, not shown). The magnets are of ferrite, stuck with adhesive, and preferably protected by a resilient coating.
