Abstract: 1,121,242. Gear-cutting. GLEASON WORKS. 25 Jan., 1967 [29 March, 1966], No. 3697/67. Headings, B3K and B3L. [Also in Division F2] A drive transmission especially for a gear cutting machine of the type described in Specification 1,066,692, includes a screw and nut gear element in association with bevel gearing operating to augment the main drive torque by the action of viscous shear in a lubricant film. A motor 14 drives a barrel cam 13 operating an oscillating link 24 connected to a slide bar 33 oscillating the tool cradle 11 through a tape 35. The bar 33 is coupled to a second oscillating link 36 operating the screw and nut gear 43, 46 driving an output shaft 48 rotating the workpiece G through gearing 51, 52 and 54, 55. Shaft 48 carries a disc 65 mounted between bevel pinions 66, 67 driven through a pinion 71 by the motor 14 at a higher speed than the maximum attainable by disc 65. The latter carries friction discs 78, 79, Fig. 2, formed with radial grooves (82) to which oil is supplied from an inlet 84. If the screw and nut gear operates to thrust shaft 48 to the right the viscous shear torque generated between pinion 67 and disc 79 augments the drive torque to an extent proportional to the shaft thrust, and if the thrust is reversed a similar effect is obtained between pinion 66 and disc 78.

Title: Improvements relating to automatic selecting circuits for telephony
IPC: H04Q3/00
Filed: 1929-02-04
Abstract: 308,296. Soc. Nouvelle de Constructions Telephoniques, Brevets Tchoubritch Derval, (Assignees of Tchoubritch Derval & Co.). March 21, 1928. [Convention date]. Automatic exchange systems.-Consists in a number of modifications in the system described in Specificaticn 288,547 in which a calling line is connected over front contacts of its line relay A and over an idle link such as II<2> to the calling side of an associated feed group E - - O, and a wanted line, selected say by a two-digit marker, is connected over back contacts of the line relay and over the same link to the called side of the feed group. Connection of calling line to link and feed group. Each line is provided with an auxiliary relay D' which is energized by the line relay A and cut off by the cut-off relay and energizes the relay C of the first idle link via the circuits 13, 9 and a chain circuit 100 involving contacts of the relay K in the feed groups of the preceding link. This avoids even a momentary operation of the C relays of other idle links. Seizure of idle marker. The busy relays R, R<1> in the marker groups and the seizing relays P, P<1> in the feed group are so arranged that when both markers are idle the energization of K can only energize P to seize the lower one, a momentary operation of P<1> being avoided. Selection of wanted line. Relay K instead of being made sluggish is locked independently of E while H is energized i.e. until both digits have been recorded. In addition to minor changes, the following modifications are made in the marker circuits. The relay Y, which prepares the marking circuits, locks itself until the marker is released (instead of falling sluggishly on the relapse of V). The tens and units marking circuits are fed from a common ground over 73 (instead of from ground and battery respectively), and the calling side marking circuit 30 is not made until the relapse of X which opens circuit 73. This prevents interference with the operation of the units relays D. These relays are connected to battery permanently instead of to ground over contacts of the respective tens relays. Release. Relays K, L do not fall back to release the connection until both subscribers hang up. When either hangs up, an additional relay SR connects up a tone to the talking circuit to notify the other.

Abstract: 370,548. Saddles. JELLEY, H., Wynbourne, Warwick Road, Solihull, near Birmingham. Feb. 6, 1931, No. 3768. [Class 136 (iii).] In order to prevent chafing of the rider's thighs, the sides or parts of the sides of a saddle top are so moulded or shaped that the side parts or flaps are permanently incurved or given a pronounced rolled-under section, so that the edges of the incurved parts are located underneath the seat, but are normally separated by a substantial clearance, so as to allow space for the passage of the saddle pin and for inward deformation under load. Fig. 4 shows a cross section at the region of maximum incurvature. The top is preferably produced by die-moulding from a fabric-reinforced and vulcanized rubber composition. One moulding operation may give the material an initial shape approximating to that of an ordinary top, while one or more succeeding moulding operations may give the permanent incurvature to the skirts and adjacent side parts.
