Title: Improvements relating to automatic gramophones or like musical instruments
IPC: G11B3/085
Filed: 1928-07-11
Abstract: 321,667. Automatic Musical Instrument Co. July 15, 1927, [Convention date]. Divided on 293,867, Returning sound-box to starting point. - The positioning and return movement of the tonearm of an automatic gramophone, such as described in Specification 293,867, is controlled by a cam drum having peripheral grooves for raising and lowering and for swinging the tone-arm, and end cams for controlling the intermittent drive of the drum. A horizontal cam drum 177, is intermittently driven for half revolutions by gearing and clutch mechanism controlled by a spring- retracted lever 168 pivoted to a link 166 which is pivoted at 167 to the frame and supported by a lever 165. After a record has been supplied to the turntable, a lug on a central drum which makes one revolution for each selection and playing of a record rocks the lever 165, thereby rocking the link 166 so that the lever 168 pivoted thereto is withdrawn from a collar 299 on a shaft which can then be moved by a spring into clutch engagement with a driving shaft. The cam drum 177 is thereby driven for a part revolution, peripheral cam grooves 178, 186 thereon acting through linkages to swing the tone-arm 185 to starting position and to lower it so that the needle engages the first groove of the record, whereupon an end cam 195 on the drum presses back a plunger 194 to rock the lever 168 so as to move the collar 299 and disengage the clutch driving the drum. As the tone-arm 185 tracks the record, it acts through linkage 199 to slide a notched bar 201 through a catch 203 on the link 166, and on completion of playing, the stylus enters an eccentric groove which effects a small return movement of the bar 201 whereby it pulls down the catch 203 and link 166 and withdraws the lever 168 so that the clutch can again engage and cause a further part rotation of the drum 177. In this rotation, the cam grooves 186, 178 lift the tone-arm and swing it to initial position, the end cam acting on a plunger 204 to press back the notched bar 201 clear of the catch 203, and the plunger 194 being finally pressed back so as again to operate the lever 68 to disengage the clutch. Just before the cam drum 177 completes its second part revolution, a lug thereon rocks a lever to operate through a linkage the clutch for driving a control drum from which the various movements of the automatic gramophone are actuated.

Title: Improvements in telecommunication systems with alternative routing facilities
IPC: H04Q3/00
Filed: 1946-10-14
Abstract: 646,374. Automatic exchange systems. COMPAGNIE GENERALE D'ELECTRICITE. Oct. 14, 1946, No. 30535. Convention date, May 2. [Class 40 (iv)] In an alternative rout ing system, traffic relays 1, 2 and 3, Fig. 2, operate at an exchange A when the traffic intensity in the arm AB of a net. work (Fig. 1) reaches 80, 90 and 100 per cent respectively. Relays 4, 5, 6 corresponding to arm AC, and the traffic is directed over the route carrying the least traffic. Marking wires B<SP>1</SP>, D<SP>1</SP> correspond to stations B, D and marking wires A<SP>1</SP>B<SP>1</SP>, A<SP>1</SP>C<SP>1</SP> correspond to junctions AB, AC. Relay 7 is controlled by the traffic relays 1 to 6 to direct calls for exchange D over junction AB or AC in accordance with the relative intensity of traffic on the two junctions. Relay 8 diverts calls for exchange B over junction AC when the traffic intensity on AB reaches 100 per cent and relay 3 operates. If the traffic on junction CD is heavy, a traffic regulating device at exchange C signals exchange A over conductor T to operate relays 9, 10. Relay 9 falls back at the end of the signal but 10 is held and relay 7 is disabled so that no further calls can be directed over junction AC. Relay 10 is released to free relay 7 when a further signal is sent by exchange C over T2 when the traffic on CD diminishes. Relay 14 operates to release 10 and the sender at C is released by a battery signal applied to conductor A. Exchange C. Similar traffic regulating equipment is installed at C. Heavy traffic on CD operates relay 6, relay 12 follows and a sender S is seized by ground on wire M. The sender S signals exchange A to operate relay 9 at A over conductor T. The sender also operates relay 13 and releases itself, but is seized again if the traffic falls and releases 6, 12. When the sender is seized a second time with 13 already operated, it signals exchange over conductor T2, operates relay 14 and is released by an acknowledgement signal from exchange A. Specification 23305/46, (as open to inspection under Sect. 91), is referred to.

Abstract: 669,816. Knitting. MILLER, I. L. (Miller, M. C.). Nov. 19, 1947 [Dec. 6, 1946], No. 30687/47. Class 74 (ii). A knitted stocking blank comprises an ankle and upper heel portion consisting of a series of courses extending right across the blank with a heel group of loops at each end of each of said courses, the said groups being stepped outwardly in selected ones of said courses to provide left and right upper heel areas of constant width and the intervening group of loops in that course next following each of the selected courses having loops added at each end thereof to provide at each end of the series of intervening groups an interposed instep area of increasing width with-series of eyelets forming lines of demarcation between the upper heel areas and the interposed instep areas; and left and right lower heel. areas constituted by series of short courses knitted as extensions of the upper heel areas at each side of the fabric while knitting is suspended upon the intervening terminal wale loops of the whole instep .area. The loops of the wales forming the rectangular upper heel areas 16 at the sides of the blank are stepped outwardly at selected courses during knitting of these areas and the instep area 18 is correspondingly progressively widened, by the addition of loops at each side thereof, to provide additional triangles 20 of instep fabric, separated from the areas 16 by lines 22 of eyelets. Strengthening courses 24 are then knitted entirely across the fabric. Thereafter, two inwardly tapered gores 26, 28, and, if desired, a third gore ending at the line 30, are formed at each side of the blank by progressively shortening the courses at their inner ends. The foot is then knitted across the entire width. Preferably, the apices of the gores are on the same or closely adjacent wales and substantially on the eyelet lines 22. An upper gore 38, Fig. 3, formed, as above, by narrowing, may be followed by a gore 40 having an initial short course and following courses successively lengthened at their inner ends to produce a pronounced eyelet formation between the gores. Left and right groups of narrowing points step the heel area loops outwardly in forming the areas 16, 20 and, during knitting of the heel gores, function as pressers, the needles being held out of engagement with the usual press edge. The heel areas 16 may be formed with the yarn carriers used for the spliced ankle portion; or an additional splicing yarn may be employed to reinforce them.
