Abstract: 689,282. Spinning spindle apparatus. HISPANO SUIZA (SUISSE) SOC. ANON. Feb. 20, 1951 [Feb. 27, 1950], No. 4147/51. Class 120(ii) [Also in Group XXXIV] A textile spinning spindle of the kind driven through a worm wheel and worm has a spindle blade that is slidable vertically against spring means s whilst the driving connection is maintained, the blade also carrying an abutment adapted to bear on a shoulder carried by the frame, so as to limit the downward displacements s of the spindle. A worm shaft 4 driven by a worm wheel 3, is coupled to an intermediate sleeve 13 by means of a rubber cone 12, the sleeve 13 driving the copcarrying spindle blade 6 through a friction -coupling. Alternatively, the intermediate sleeve 13 may be dispensed with and the spindle 6 associated directly with the cone 12. The friction coupling between the sleeve 13 and spindle 6 comprises a friction disc 14 slidable on the spindle 6, with which it is rotatable, and pressed against the upper edge of the sleeve 13 by a spring 15 bearing against a member 16 fixed to the spindle 6. In order to provide a resilient mounting for the spindle 6, an upper bearing 9 is held in a tube 10 by a rubber ring 11. The tube 10 has an internal shoulder 10a which acts as a stop for the member 16 when the spindle 6 is pressed violently downwards.

Title: Improvements in picture frames
IPC: A47G1/06
Filed: 1978-09-13
Abstract: A picture frame described herein includes a backing and an outer rim defining with the backing a recess for receiving a picture or the like and a transparent covering therefor. Through the backing is provided at least one slot and preferably at least one group of substantially parallel slots. Each slot has a cross-section whose diameter increases in a direction from the rear face to the front face of the backing.

Title: Preparing Polyolefins With a Narrow Particle Size Distribution and Catalyst Therefor
IPC: C08F10/00
Filed: 1978-09-26
Abstract: Ziegler type catalyst components suitable for activation with an organo aluminum compound are prepared by mixing the active catalytic particles with a fibrillatable polyolefin or substituted polyolefin and a non-fibrillatable polyolefin or substituted polyolefin followed by (for example) ballmilling the mixture for a period of time sufficient to cause a fibrous mat to form, entrapping the catalyst particles in the mat which is, in turn, carried by the non- fibrillatable polyolefin. "Fibrillatable polyolefins" embodied are P.T.F.E. and ethylene-propylene copolymers, whilst "non-fibrillatable polyolefins" embodied are polyethylene, polypropylene, ethylene-propylene copolymers and polyvinylchloride. Polyolefins prepared by contacting the alpha olefin with such a catalyst component activated by an organo- aluminum compound have a particle size and particle size distribution such that 98% of the product is retained on a 100 mesh screen.

Title: Testing of induction motors
IPC: G01R31/34
Filed: 1979-02-01
Abstract: A method of and apparatus for testing induction motors is described which enables the condition of the motors to be monitored during normal operation. Any defect in the rotor circuit causes the torque to vary as the defective part interacts with the stator field and hence causes speed variations at twice the slip frequency. By means of transducer 12 (Figure 1), the time instants of rotor passage past a datum point are determined and, by using a ramp circuit 22 and a rotating time base sweep, an oscilloscope 20 displays the relationship between period of rotation and phase angle at the slip frequency and indicates the amplitude of the speed fluctuations at twice that frequency. <IMAGE>
