Abstract: 1,233,013. Sawing and mitering. EUGEN LUTZ K.G. 28 Nov., 1968 [3 Jan., 1968; 10 May, 1968], No. 56477/68. Heading B5L. In a bench and mitre saw having a motordriven circular saw blade 14 and a different work-receiving surface for each use of the saw to serve as a bench saw plate and as a mitre saw table respectively, the work-receiving surfaces are provided on the opposite sides of a work-plate 2 which can be rotated through 180 degrees about a horizontal axis, and has a circular disc 11 rotatably mounted in it in a circular recess. The saw blade 14 is pivotally mounted on the disc on the side of the workplate which is adapted to serve as a mitre saw table, and is adapted to enter a slot 27, 27a in the work-plate 2 and then to be locked by a locking device in a fixed position. In this position, after the work plate has been rotated to the Figure 3 position, the saw blade projects for the necessary cutting height from the other side of the work-plate. In the machine described the work-plate 2 is pivotable about pins 3 in a frame 1, and the disc 11, Fig. 2, carries a bushing 12 to which is pivoted a saw housing 16 carrying a motor 15 and saw blade 14. The housing 16 is urged upwardly by a spring 18 and is pulled downwardly by means of a handle to cause the blade 14 to form a mitre cut on a workpiece 21 by entering the slot 27 in the disc 11. The angle of the mitre cut is adjusted by rotating the disc 11 relative to a fixed guide bar 8, the saw blade 14 moving with the disc. When it is desired to use the saw for bench sawing, the disc 11 is rotated until the slot 27 therein is aligned with a slot 27a in the work-plate 2. The housing 16 is then pivoted downwardly to cause the blade 14 to project substantially through the slots 27, 27a and is held in this position by an adjustable locking device comprising a bolt 32 inserted into a bearing part 33 on the housing 16. The work-plate is then pivoted through 180 degrees to the position shown in Fig. 3. A combined blade guard and splitting wedge 37 is attached to the housing 16 and guide bars, e.g. 39, are attached to the work-plate. An extension to the work-table may be provided by a plate slidable on guide rods secured to the frame 1.

Abstract: 1,250,296. Ionization detectors. CERBERUS A.G. 19 May, 1970 [19 May, 1969], No. 24148/70. Heading H1D. In an ionization fire-alarm device of the type comprising a detecting ionization chamber 6 connected electrically in series with a resistance element, e.g. a further ionization chamber 9, an electrode 7 of the detecting ionization chamber is in the form of a plate arranged to shield the interior of the chamber from an electrical circuit 13 to which that electrode is connected. The device has a base 1 secured to a supporting surface 2, e.g. the ceiling of a room, and shaped to direct smoke-containing air into apertures 4 in a housing 5 forming the second electrode of the chamber 6. Electrode 7 is preferably disc-shaped and carries radioactive material 8. Reference chamber 9 has a discshaped electrode 10 carrying radioactive material 11 and a surrounding cup-shaped electrode 12 which does not allow the entry of aerosols but permits pressure equalization with the ambient atmosphere. Electrode 12 is formed in part at least as a flexible membrane which can be deformed by a screw 15 to adjust the electrode spacing. Circuit 13 may consist of a field-effect transistor and load resistors or an integrated circuit with an amplifier element and a further semi-conductor device, and is preferably encapsulated in insulating material. An adjustable resistor 14 may be provided for adjusting the sensitivity of the device. Grooves 16 are provided in a surface adjacent the electrode 7 to lenthen the leakage path.

Abstract: 1,252,620. Telegraph exchanges. SIEMENS A.G. 10 Dec., 1969 [11 Dec., 1968], No. 60238/69. Heading H4P. In a telegraph exchange system having a plurality of single-current/double-current converter circuits, wherein during the development of a connection, a controlling exchange transmits a monitoring signal to a particular selected converter circuit, each converter circuit is designed to allow the received monitoring signal to be reflected to the controlling exchange, which is adapted to analyse the transit time and/or the duration of said reflected monitoring signal in order to ascertain the operational condition of the converter circuit affecting that particular reflection. In Fig. 2, which is similar to Fig. 1 (not shown), contact (f) is omitted hence a signal on wire b2 is reflected on wire a2 the polarity of which depends on the condition of the converter circuit. If a controlling exchange supplies a monitoring pulse to b2, contact b contacts with +TB polarity hence winding A1 is energized. Contact a is also connected to + TB polarity hence this is reflected back to the controlling exchange. Each converter circuit may be permanently assigned to a subscribers line, for example, in the case of a TDM exchange (see Fig. 4, not shown). In this arrangement line a1 is connected to line b1 through contacts (sk) which are closed in a dialling condition thus energizing receiver relay (EM).

Abstract: 1,258,717. End-face seals. FORSHEDA GUMMIFABRIK A.B. 30 Jan., 1970 [31 Jan., 1969], No. 4565/70. Heading F2B. An arrangement for mounting and axially fixing a rubber shaft seal having a sealing lip adapted to bear axially against a housing sealing surface comprises a support 26, Fig. 3, against which an annular supporting surface on the rubber seal slides on rotation of the shaft, the support being so located in relation to the housing sealing surface that the sealing lip takes up the correct axial position in relation to the housing sealing surface after the shaft has'completed a single revolution. The support shown in Fig. 3 is rotational and arranged to engage a conical end face of the rubber seal; when the shaft starts rotating, the support pushes the remaining parts of the rubber seal towards the housing 22. The support may be formed integrally with the housing, Figs. 1 and 2 (not shown), as a detachable member 36, Fig. 5a, arranged to engage two annular supporting faces on the rubber seal, as an invertable metal washer or coil of wire 76, Fig. 9, arranged to engage a groove 79 during the mounting operation but invertable to the position shown chain-dotted thereafter. In Fig. 14, the support is L-shaped for engaging a recess and in other embodiments, Figs. 10a to 13 (not shown), the support is made of bent sheet metal and attached to the housing by spot welding. In Fig. 6, (not shown), a rubber shaft seal is mounted one each side of a partition wall for engagement therewith.

Abstract: 1297913 Detecting infrared radiation TECHNOLOGY MINISTER OF 26 Oct 1962 [26 Oct 1961] 38433/61 Heading G1A In an infrared radiation detection system in which radiation is focused by a lens 3 on to a chopper disc 1, the chopped radiation being directed by a lens 4 on to an indium antimonide detector cell 5, the disc is of glass and comprises alternate segments 6, 7 which, respectively, transmit the radiation and effectively block it, the segments 7 being etched so that unwanted radiation from internal sources and the chopper itself is diffused and the amount of such radiation reaching the cell is significantly reduced. Unwanted radiation from external sources may be nullified by making the segments 6, 7 of interference-type filters as disclosed in Specifications 1297911 and 1297912 whereby the desired radiation is transmitted by the segments 6 whereas the unwanted radiation passes equally through the segments 6, 7 and is therefore not chopped.
