Filed: 1972-12-13
Abstract: 1386457 Road traffic signals on vehicles SWF - SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 13 Dec 1972 [12 Feb 1972] 57561/72 Heading G4Q An arrangement for dimming vehicle direction indicator flashing lamps BLh1, BLh2 and brake lamps BrL1, BrL2 comprises a flasher unit BG, a direction indicator switch FRS, a brake switch BS, resistors W, W1, W2 which are introduced into the lamp circuits when the vehicle light switch LS is closed, and fog lamps NL1, NL2 operated by switch NS, the lead from the fog lamp switch to the fog lamps being connected at N to the means for dimming the direction indicator and fog lamps, so that when the fog lamps are switched on, dimming of the other lights does not take place. The resistors are introduced into the circuits by the action of relays R0, R1 arranged in parallel. Compensating resistors W3, W4 provide a uniform load to the flasher unit when the indicator lamps are dimmed. When the fog light switch NS and the vehicle light switch LS are both on, the same potential is applied to the points N and 58 so that the relays do not operate. The relays may alternatively be arranged in series.

Title: A Screw-Thread-Cutting Lathe.
IPC: B23G1/02
Filed: 1966-12-22
Abstract: 1,156,102. Screw-cutting lathes. H. ERNAULT-SOMUA. 22 Dec., 1966 [27 Dec., 1965], No. 57602/66. Heading B3T. A screw-cutting lathe comprises a saddle 1 guided on a bed 2, a longitudinal carriage 3 slidable on the saddle, a transverse carriage 6 movable on carriage 3, first cam and follower means 36, 35, for moving the cutting tool 7 towards and away from the workpiece 64 at the end of each pass, and a second cam and follower means 54, 53, for providing depth of feed to the tool. The movement of carriage 3 parallel to the work axis is produced by a cam 10 keyed to a shaft 11, and a follower 17 on the carriage; shaft 11 being driven from the lathe spindle 16 via a spindle 15, and gears 13, 14. Carriage 6 is urged to the right by a spring 20, Fig. 2, and an adjustable straight edge 22 co-operates with a roller 23, adjustable by a handle 31, so that depending on whether the straight edge is set so as to be parallel with the work axis or not, a cylindrical, or taper thread is produced. A spring-urged lever 33 is mounted on an eccentric 37, carried by a shaft 38, and engages at one end in a notch 34 formed in a slide 25, and at the other end carries the follower 35. Splined to shaft 38 is a graduated disc 43, and a sector 44 provided with ratchet teeth, which co-operate with a retaining pawl 46, and a drive pawl 48, the latter being pivoted on a spring-urged oscillating arm 50 which carries follower 53. A lever 55 is held in the Fig. 5 position by a locking lever 58, which when released, allows lever 55 to engage the pawls, and disconnect them from the ratchet teeth. A lug 61 is adjustably fixed on the sector 44, and is adapted to engage lever 58, so as to disengage lever 55. In operation, starting with carriage 6 in the withdrawn position, shaft 11 rotates so that cam 36 pivots lever 33, and the tool moves up to the work. Cam 10 rotates, and moves carriage 3 along the work for the first screwing pass. Lever 55 is manually operated so that it is looked by lever 58, and pawls 46, 48 co-operate with the teeth of sector 44. For each rotation of shaft 11, cam 54 causes an angular movement of shaft 38 corresponding to one tooth of sector 44, which occurs during the withdrawal movement of carriage 6. The eccentric 37 of shaft 38 occupies a new position at each rotation of shaft 11, and consequently the tool is fed further towards the workpiece after each pass, until lug 61 acts on the end of lever 58, whereupon the pawls are released, and the levers move back to their original positions.

Title: Automatic telephone answering devices
IPC: G11B31/00
Filed: 1972-12-14
Abstract: 1411138 Telephone answering machine PIONEER ELECTRONIC CORP 14 Dec 1972 [16 Dec 1971] 57792/72 Heading H4K In an answering machine means are provided for monitoring the recording medium so that when the amount of available medium falls below a predetermined amount the medium is changed as soon as the existing call terminates. The machine may use an automatic cassette changing mechanism of the type disclosed in Specification 1,399,534. The amount of available medium is determined utilizing a tape counter or by observing the speed of the tape supply reel with the aid of a rotating bridging contact or a magnet mounted on the reel hub. The more rapid short circuiting of a pair of open contacts or the operations of a reed switch when the reel is rotating more quickly towards the end of the tape carried thereby, permit the charge on a capacitor to be built up so as to energize a relay. A contact of the latter then prepares a driver circuit which actuates a cassette changer as soon as the current call ceases. Transistors and Zener diodes are used in the capacitor charging and driver circuits.

Abstract: 1,153,319. Clipping circuits. FUJITSU Ltd. 23 Dec., 1966 [25 Dec., 1965], No. 57798/66. Headings H3P and H3W. A method of amplitude control in the extracting of timing waves in pulse code transmission comprises applying an input signal, including a timing wave component, of symmetrical waveform but variable amplitude, to a slicing circuit, the slicing voltage of which is determined by either the amplitude of the input signal or the pattern density of the input signal or both, so as to reduce the amplitude variation of the input signal at its output. In a first embodiment dependent on signal amplitude the slicer comprises a diode D 1 , Fig. 5, which derives a bias via smoothing circuit R 1 , C 1  from a second diode D 2  which is fed with the incoming signal via transformer I, II. The incoming signal may be converted, before application to the slicer, to cosine squared form. In a second embodiment, dependent upon pattern density, the signal is applied to a diode D 1 , Fig. 6, which is selfbiased by means of R, C circuit R 2 , C 2  in series with the load resistor R 1 . The two arrangements may be combined (Fig. 7, not shown).

Abstract: 1410619 Photo-electric indication of tape tension BELL & HOWELL CO 15 Dec 1972 [17 Dec 1971] 57912/72 Heading G1A [Also in Division G5] A device 29 for sensing tension in a web or filament, particularly tape in a tape recorder, comprises tape guides 47 mounted on a rotatable plate 46, the tensioned tape engaging the guides 47 to rotate the plate 46 against the bias of an axial torsion spring 56 away from a stop 68 which defines the zero-tension position, an electrical signal being generated which is indicative of the angular position of the plate, by means of a disc 71 which rotates with plate 46 on a shaft 44 and which modulates a light beam, a unique signal also being produced in the zero-tension position. The disc has areas 83-85 which are respectively opaque, transparent, and of transmissivity linearly varying with angle, and is disposed between photocells 74, (75) Fig. 6 (not shown), and corresponding light sources 82. At normal tensions, area 85 modulates photo-cell (75) to provide a linear output, while photo-cell 74 is under transparent area 84. If the tension drops to zero, e.g. by the tape breaking, the spring 56 rotates the shaft 44 so that a finger 70 engages the stop 68, and opaque area 83 then moves over the photo-cell 74, causing the tape transport to stop. Two guides 47 are rotatably mounted on the plate 46, equidistantly from the rotational axis of the plate. The torsion spring 56 is contained in the hollow bore 55 of the shaft 44 and its lower end is secured at 58 to an adjustment knob 61 which can be rotated to adjust the spring bias and can then be clamped to housing 30 by an element 65. The photo-cells, and the light source 79 and light pipes 82, are mounted on a circuit board 76 having projecting connectors (78) Fig. 5 (not shown).

Title: Aliphatic amido-amines
IPC: C07C233/45
Filed: 1978-08-18
Abstract: The reaction of an imidazoline base of the formula:-   <IMAGE> wherein R represents an aliphatic group comprising from 6 to 22 carbon atoms and R1 represents a substituted or unsubstituted alkyl or alkenyl group comprising from 1 to 4 carbon atoms, with a carbo-alkylating agent is carried out in two stages. Initially the pH is maintained in the range 7 to 11 and subsequently it is maintained in the range 9 to 12.5. These conditions encourage at least part of the imidazoline to undergo alkylation followed by hydrolysis and further alkylation. The di alkylated amido- amines thus produced are believed to be novel. The reaction products are surfactants which exhibit very low skin irritancy and have a desirably low viscosity. They find particular application in shampoo formulations.
