Abstract: 935,867. Frequency selective signalling. WESTERN ELECTRIC CO. Inc. Sept. 21, 1961 [Oct. 3, 1960], No. 33784/61. Class 40 (4). In a system in which signalling digits at two or more distinct frequencies are transmitted over a speech channel and in which the receiver includes a plurality of digit channels, each channel including a band elimination filter to eliminate from the channel digits other than the digit to which the channel is required to respond, the output of each channel is cross coupled to the inputs of the other channels to slightly attenuate the wanted signals, relative to " out of digit channel " signals, in order to decrease the probability of a noise or speech signal being interpreted as a digit. The invention is described with reference to a system utilizing a two-digit frequency coded signalling system in which the signals at the receiver are applied to adding networks in the inputs of two amplifying transistors 2 and 3, Fig. 1, feeding band elimination filters 4 and 5 whose outputs are coupled via phase correcting networks to the adding circuit at the input of the other channel, producing a response as indicated in Fig. 2, in full line for the upper channel of Fig. 1, handling the lower sub group. The lower sub group, i.e. the wanted signal, being slightly attenuated and the upper sub group severely attenuated, relative to the remainder of the band. The outputs from the two channels are fed to limiters and frequency selective registers, Fig. 3 (not shown). Specification 854,375 is referred to.

Title: Improvements in or relating to machines for applying closures to cans or like containers
IPC: B21D51/32
Filed: 1936-12-10
Abstract: 486,862. Closures for cans and like containers. PAICE, A. M., [Representative of PAICE, F. E.], and DIVINE, C. J. Dec. 10, 1936, No. 33917. [Class 125 (ii)] In a machine for applying closures to cans and like containers the crowning aperture is formed by a number of parts which can slide away from each other to expand the aperture beyond the size which enables its edges to support the closure. The shoot 16 has a guide channel down which the closures 37 move to the crowning position vertically below the plunger 32. A closure then rests, as shown in Fig. 4, upon the edge of an aperture formed in the opposing ends of sliding plates 43, 44 and its further movement is prevented by stops 54, 55 on the plates. The sliding movement is limited by pins 50, 51 working in slots in the plates. Springs 47 attached to the extensions 45, 46 urge the sliding plates 43, 44 towards each other. The edges of the aperture are chamfered to suit the neck of the container to be closured. The container 13 stands on a resilient pad on its table and as it is lifted its mouth passes through the aperture and picks up the closure 37. Further movement causes the container neck to engage the plates 43, 44 and force them outwards. This movement also brings the closure against the plunger head 32 and finally places the mouth of the container and its closure into the throat 34 where the sides of the closure are forced into close engagement with the rim of the container. The withdrawal of the container is assisted by the spring 27 acting on the plunger and the parts return to their initial positions. Reference has been directed by the Comptroller to Specification 170,535, [Class 125 (ii)].

Title: A gear-shaping machine of the kind having a pinion as the cutting tool
Inventor: CARR HERBERT
IPC: B23F23/12
Filed: 1959-10-08
Abstract: 891,507. Gear-cutting. DRUMMOND BROS. Ltd. Nov. 8, 1960 [Oct. 8, 1959], No. 34149/59. Class 83 (3). A gear-shaping machine comprises a feedcam 1 co-operating with a follower 3 for causing relative movement between a pinion cutter and a workpiece and for allowing a complete revolution of the workpiece at the full depth of cut, and means for moving the feed cam bodily as soon as the revolution is complete to cause the work and tool to be sharply separated. When the roller 3 reaches the point 8 at which a sharp withdrawal movement is desired, there is a delay while the cam rotates through the angle α. The invention therefore provides a bodily axial or transverse displacement of the cam. To this end, the cam-shaft 2, Fig. 2, is supported at one, or both ends, in an eccentrically-mounted lever 11. The lever is rotated by a spring 30 as soon as a plunger 31 slips into a recess 29 in a cam 28, the shaft 2 continues to rotate until the plunger 31 has cleared the recess 29 and the machine is then stopped automatically. Specification 891,506 is referred to.
