Title: Improvements in cylinders and pistons for internal combustion engines
IPC: F02F1/18
Filed: 1918-01-21
Abstract: 142,516. Bradshaw, G. E. Jan. 21, 1918. Pistons; connecting-rods.-In order to improve air or water cooling, and to secure compactness, the cylinders of air-craft or other internal-combustion engines are made of stream line, elliptical, oval or ovoid form in cross section, with pistons of corresponding form. The piston, shown in inverted plan in Fig. 4, may have cross ribs for strengthening and cooling. In order to steady the piston the gudgeon-pin bearings are placed wide apart, and two connecting-rods may be employed. In the latter case, a third bearing is preferably interposed between the bearings 10. In a radial-cylinder engine the piston skirt is cut away or bent back as shown at 12<a> and 12b, in order to prevent fouling of adjacent pistons. The skirt may be similarly cut away to prevent fouling of the balance weight or other parts. Specification 102,186 [Class 7 (ii), Internal-combustion engines, Arrangement &c. of] is referred to.

Title: Telecommunications exchange systems
IPC: H04Q3/54
Filed: 1974-02-28
Abstract: 1462653 Automatic exchange systems SIEMENS AG 28 Feb 1974 [9 March 1973] 9141/74 Heading H4K A subscriber line circuit comprises a first gate which is enabled in response to the application of a code representing the directory number of the subscriber associated with the line circuit and a second gate which is enabled in response to the application of a code representing the equipment number of the line circuit, the output of the second gate being coupled to an output of the line circuit such that an output is only produced in response to the application of said equipment number code if the subscriber circuit is free. The arrangement is used in a PBX having a single ended switching network K, and in which a calling subscriber is connected through to a register WE, in known manner. Dialled digits are transferred from the register WE to a store P associated with a central control Z which determines whether the digits relate to an internal or external call. An external call is set up in an undisclosed manner. For an internal call, the central control causes three groups of ten wires R1, R2, R3 to be marked in accordance with a three figure directory number of the called subscriber and these markings are extended to all line circuits such as TAI. In the line circuit of which ten position switches D1- D3 are set to the directory number marked on the wires R and a gate G1 is enabled in conjunction with a mark supplied from the central control to all such gates G1. A hunting impulse is thus supplied to a scanner S via OR gate G3 and the marked line circuit is identified according to a three figure equipment number by the scanner S which transmits this number to central control. Central control then marks the code wires R according to this equipment number and enables gates G2 provided in each line circuit, and coupled to the code wires in accordance with the equipment number of the respective line circuit. In the identified line circuit, gate G2 provides an output via a contact b and OR gate G3 to the scanner S if the line circuit is idle. The scanner is thus caused to hunt for the marked line circuit so as to indicate to central control that the line circuit is free, i.e. a "line state" scan is performed. Had the line circuit been in use, i.e. the associated subscriber engaged, the contact b would have been open and the mark would not have been supplied to the scanner. If the scanner is of the type which establishes the identity of an equipment number in a series of stages, only the first stage may be used for the "line state" scan, e.g. the scanner'may only establish that a line circuit in the hundred's group has been marked. The switches D1-D3 permit the directory number associated with a particular line circuit to be easily changed.

Title: Automatic phonographs
IPC: G11B17/02
Filed: 1942-07-03
Abstract: 558,528. Automatic gramophones. PHILCO RADIO & TELEVISION CORPORATION. July 3, 1942, No. 9217. Convention date, Aug. 21,1941. [Class 40 (ii)] Relates to trip mechanism responsive to the quick movement imparted to the pick-up arm by the eccentric or quick pitch inner groove of record discs for initiating the record changing and pick-up return devices. According to the invention, an arm 11 rotating with the pick-up arm carries an insulated bracket 12 supporting a pivot 14 with a roller 16 and an electric contact arm 15. The arm 15 is biased by gravity and a light spring 20 to rest normally by means of a rubber cushion 19 on a set screw 18. During the inward travel of the pick-up, the roller 16 engages the under surface of a plate 22 and is thereby rotated to cause the contact 17 at the end of the arm 15 to approach the plate 22. But a cam 7 on the hub of the turntable periodically rocks a lever 24 pivoted at 25, and a set screw 27 at the end of lever 24 thereby periodically lifts the plate 22 off the roller 16, so that the arm 15 periodically moves back to its set screw stop 18 before the contact 17 can reach the plate 22. When, however, the quick movement of the pick-up arm occurs at the end of the playing of a record, the contact 17 reaches the plate 22 and closes the circuit of a solenoid 28. A lever 36 attached to the core of the solenoid is turned about its pivot 37, a roller 38 on one end of the lever 36 is withdrawn from locking engagement with a notch in a cam disc 29, and a clutch member 33 at the other end of the lever 36 is brought into engagement with a clutch member 34 on the hub of the turntable. Motion is then transmitted through gearing 32, 31, 30 to the cam disc 29, which makes one revolution and is then again locked by the roller 38. The rotation of the cam disc 29 serves to control any suitable record changing mechanism and to return the pick-up. A cam follower 43, 41 is attached by a spring 42 to the arm 11, which rotates with the pick-up arm. The cam disc 29 first lifts the follower 43, 41 which lifts the pick-up. Then the cam disc moves the pick-up out to allow the record changing to take place. Finally, the cam disc moves the pick-up arm inward over the edge of the fresh record and drops it on the starting groove. The pick-up arm may be operated by the mechanism described in Specification 556,974.

Abstract: 985, 448. Weighing apparatus with automatically applied roller weights. SCHEMBER A.G. WAAGEN-UND MASCHINENFABRIK. March 12, 1962 [March 10, 1961], No. 9467/62. Heading G1W. In an automatic rolling Weight weighing apparatus the load is transmitted through rods 1, 2 (Fig. 1) to an inclination (pendulum) balance 3 and to a beam 4 respectively. The beam 4 consists of four balance arms 5, 6, 7, 8 (Fig. 2) mounted in a frame 10 by a shaft 9. Roller weights 13, 14, 15, 16 rides in respective beams each beam having ten notches corresponding to the digital sequence 0-9, except the beam 8 for the smallest value decade which may be extended by one or more divisions. Each weight is transported by a fork 17, 18, 19, 20 (Fig. 2) respectively to a notch corresponding to the balanced position of its associated beam. The forks are displaced by racks 21 engaged by gears 22, 22<SP>1</SP> loosely arranged on a shaft 23 which is driven by a motor through gears 24, 24<SP>1</SP>. Electromagnetic clutches couple each gear 22, 22<SP>1</SP> to the shaft independently so that an individual toothed rack and fork may remain stationary and its associated weight remain in a notch. The clutches are actuated by contacts on the inclination system 3 which has a disc 3<SP>1</SP> with three rows of 10 contacts connected electrically to rows of contacts 27, 28, 29 adjacent and parallel to the lines of travel of the forks. A sliding contact 31 on each fork cooperates with an associated row of contacts 27, 28, 29. When the inclination system 3 is in the balanced position the disc contacts corresponding to the digits of each decade of the load weight receive current which is transmitted to the rows of contacts 27, 28, 29 and sliding contacts 31. The electromagnetic clutches and the gear-wheels driving the forks are thereby disengaged and the roller weights remain in a notch corresponding to the balance position of their associated beam. A delay relay is provided so that the weight 16 of the smallest decade is not moved until the weights of the other decades are settled. When a pointer 34 on the beam coincides with a fixed pointer 33, a shutter 36 acts on a photo-electric cell 35 to release the electromagnetic clutch 26<SP>1</SP> of the smallest weight 16, and the determined weight is printed on a printing device 37.
