Abstract: 648,032. Machinery guards. HOUNSELL (ENGINEERS), Ltd., J., and FORREST, G. S. Nov. 10, 1948, No. 29152. [Class 80(iv)] [Also in Group II] An open-topped tiltable mixing pan 10 whose mixing blades are carried by a horizontal shaft 18 coaxial with the tilting trunnion bearings 11 is provided with a guard in the form of a grid 21. The grid is carried by a horizontal spindle 22 mounted in bearings fixed to the frame 12 and on the spindle are secured a cam 24 and, at each end, a chain sprocket driving similar sprockets on a spindle 30. The cam operates a trip switch 20 arranged to stop the electric motor driving the shaft 18 upon lifting of the horizontal grid 21. A slidable rack 32 meshes with a gear 31 on the spindle 30 and carries a roller 33 cooperating with a cam track 34 fixed to the side of the pan 10. Upon tilting of the pan -by means of a handwheel 13, worm 14, worm-wheel 15, pinion 16 and toothed sector 17-to empty its contents, the rack 32 is caused at first to move inwardly, thus raising the grid and tripping the switch 20, and then to return towards its original position. In the fully tilted position of the pan the drive motor may be restarted to complete the discharge of the contents.

[Class 103 (i).] A friction disc for a brake or clutch comprises a pair of radially slotted disc members 14, Fig. 2, riveted to a hub 10 and carrying friction rings 16 and spread apart at 25 intermediate the peripheral edges 26 of the members and the hub wherebv the outer surfaces of the friction rings are inclined to a plane perpendicular to the axis of the hub. When one of the non- rotatable surfaces 22, 23 are moved to grip the disc between these surfaces engagement takes place at the inner edges of the friction rings first to give a smooth engagement. The radial slots in the discs 14 terminate inwardly in triangular openings forming independently flexible marginal segments yieldingly connected by the friction rings. In a modified form the discs 34, Fig. 3, are bent so as to be furthest apart at 37 and parallel at their outer edges from 39 to 40. The inner edges of the friction rings first engage the surfaces 22, 23, the discs then collapse until the flat surfaces between 39 and 40 engage, further compression rocks the marginal edge about point 39 to bring the outer edges of the friction rings into engagement. Finally the discs fully collapse to give an even pressure.

[Class 40 (iv).] A variable frequency-discriminating network for use as a link in a transmission system, such as a public address system, comprises input resistance or resistances, and a number of reactances of different values connected to the input resistance or resistances and selectively associated with an output resistance by a switch. The input may be applied to the whole or part of the input resistance which may include a thermionic valve. The reactances may vary in geometrical progression, and the network may be arranged to give an output of constant energy level for any position of the switch. The reactances may be capacities in series, or inductances in shunt, with the output resistance. As shown in Fig. 1, points on the input resistance R1 are connected to condensers C1-C3 selectively connected by switch 2 to one end of the output resistance R2 the other end of which is connected to one end of resistance R1. The general overall attenuation is determined by the tapping point on R1 and the values of the condensers may be arranged so that increased response to lower frequencies is accompanied by increased overall attenuation. The input resistance may comprise, between 1A and its lower end, the anode-cathode path of a thermionic valve to the grid of which the input energy is applied. Separate resistances may be used, in conjunction with each condenser, and an arrangement of this kind using a valve as part of the input impedance is shown in Fig. 4. Specification 252,078 is referred to.

Title: Improvements in or relating to stitch controls for plural-feed sewing machines
IPC: D05B27/22
Filed: 1963-07-30
Abstract: 971,862. Sewing machines. G. M. PFAFF A.G. July 30,1963 [Aug. 1, 1962], No. 30115/63. Heading D1G. A sewing machine comprising an adjustable feed dog and a pair of auxiliary feed rollers is provided with means having a lost-motion connection with the feed-adjusting means and being adapted for operation against spring bias first to move the rollers apart and then to change the feed from the forward to the reverse direction. A positivelydriven lower feed roller co-operates with an upper feed roller journalled at the lower end of a rod 8, the upper end of which is slidable in a sleeve 9 adjustably screwed into the machine frame. A spring 13 biases rod 8 downwardly. A feed dog 16 is carried by a bar 17, one end of which is forked to embrace a feed-lift eccentric 29 on a rotary shaft 28, and the other end of which is pivoted to an arm 20 on a transversely-slidable pin 19. The latter is connected by a link 21 to a pin 22, which is connected by a link 23 to a pin 24. A journalled shaft 39 carries a crank 42 and a crank pin 41, the latter being connected by a link 43 to pin 24. A rotary shaft 25 carries an eccentric 26 coupled by a pitman 27 to pin 24. The arrangement is thereby such that when shaft 39 is adjusted to align pin 41 with pin 22 no feed occurs, while progressive angular displacement of pin 41 from pin 22 in one or the other direction results in increasing rates of forward and reverse feeds respectively. A crank 40 on shaft 39 is connected by a link 38 to one arm of a double-armed lever 34 rigid with a journalled shaft 33. The bell end 35 of the other arm of lever 34 is biased by a spring 57 into engagement with a cam surface 30 on a pivoted feed control disc 32 governing forward feed. A crank 48 on shaft 44 is biased by a spring 61 to position a crank 46 on shaft 44 below a lug 47 fast with rod 8. Crank 48 is pivoted to a bar 50 which is connected by a pivotal link 58, a slidable rod 59 and a chain 60 to a pedal. A pin 51, slidably mounted in bar 50, is biased downwardly by a spring 52 to project into a longitudinal slot 53 formed in bar 50. A pin 54, projecting transversely into slot 53, is carried by a crank 55 on shaft 33. The arrangement is such that when said pedal is operated to lower bar 50, crank 46 first engages lug 47 to lift rod 8 and the upper feed roller, when pin 56 then engages pin 54 for turning shaft 33 to transfer end 35 to a cam surface 31 of disc 32 governing the reverse feed.
