Abstract: 1280388 Sets; substation circuits TELEFONAKTIEBOLAGET L M ERICSSON 29 Oct 1970 [30 Oct 1969] 51574/70 Headings H4J and H4K A telephone instrument is switchable from a loudspeaking arrangement to a low speaking arrangement. In the loudspeaking condition, (Fig. 1), the instrument uses one transducer H as a loudspeaker and the other transducer M as a microphone. On operation of a switch K (Fig. 3) by, for example, lifting the instrument, the instrument is switched to the low speaking condition and the transducer H functions as a microphone while the transducer M functions as a telephone receiver. The switch K operates to connect the incoming and outgoing conductor pairs to the transducers and, in the low speaking condition, attenuators (D 1 , D 2 ), Fig. 1 (not shown), are in circuit to provide frequency correction.

Title: Manufacture of screw-thread forming dies
IPC: B21H3/02
Filed: 1974-11-15
Abstract: 1484016 Grinding; rolling; making screw threads ALFRED HERBERT Ltd 15 Nov 1974 [17 Nov 1973] 53473/73 Headings B3D B3A and B3M A method of making a thread-forming die comprises the steps of making a rotary forming tool by forming on a cylindrical surface of a tool blank first and second groups of alternating parallel ridges and grooves of the same pitch by applying forming means to the blank, the forming means being applied in such a manner as to form between the first and second groups a further ridge or groove 9, Fig. 5, of a different pitch, and using the tool so formed to form a thread-forming die 10, Fig. 6, or an intermediate for forming the die. In order to produce the forming means, which is in the form of a crusher roller, a first grinding wheel, Fig. 1, is conventionally diamond dressed to have ridges 1 and grooves 2 of a pitch Pc which has a correction to accommodate, in the forming of a screw, the helix angle for a screw having a pitch P. The ends of the wheel have half grooves 3. The first grinding wheel 4, Fig. 3, is fed into the crusher roller to form a first group of ridges 5 and a half-ridge 6. The grinding wheel is then moved axially a distance equal to the number of ridges multiplied by the pitch Pc plus a distance X and then forms a second group of ridges with one ridge 7 of greater or lesser pitch. The ridge 7 is treated to remove a protruding portion and so as to form, as shown in Fig. 5, a broad ridge 9. The crusher thus formed is used to form a second grinding wheel which, in turn, is used to produce the die 10, Fig. 6, having a broadened ridge 9 between ridges and grooves of normal pitch. The crusher roller may, alternatively, be produced by a turning or electrolytic grinding, or a hob may be ground and used to cut the die directly. A pair of dies so produced is used to produce a screw thread having a portion of different pitch between portions of the same pitch for locking engagement with a nut, one of the dies being fixed and the other relatively movable in the longitudinal direction of the dies to form the screw thread on a blank fed between the dies.

[Class 38 (iv)] [Also in Groups XXXVI and XXXVIII] A cell used to determine the characteristic of an electrolyte has a liquid metal electrode which is constantly agitated. Water passing through a main from 24M to 30M, Fig. 14, is treated with chlorine supplied through pipe 135A and a running sample of treated water drawn through valve V3 is supplied to an electrolytic cell 10, controlling an indicator 40, which may be of the selfbalancing bridge type, and this indicator if required controls a reversible motor 31s which adjusts the flow of chlorine. The cell 10 can have various forms and either produces an E.M.F. which is a measure of the chlorine content, or is used as a conductivity cell to measure the resistance of the treated water. As shown in Fig. 1, the cell has two mercury electrodes in contact respectively with the treated and untreated water, which is supplied through valve V1, Fig. 14. The two liquids are separated by a porous partition 13, and each liquid is continually supplied through a jet 21 so as to keep the surface of the mercury agitated. The jets may impinge obliquely or tangentially to the mercury, or the mercury surface may be agitated by rotary impellers submerged in the mercury or by a spray of mercury falling thereon. If only a sample of treated water is taken then the cell either includes a standard half cell or is a resistance cell, but in both cases the treated water is supplied in a jet as shown in Fig. 1.
