Title: A transmission unit for a motor vehicle
IPC: B60K5/04
Filed: 1966-03-23
Abstract: 1,065,478. Motor vehicle driving gear. DR. ING h.c.F. PORSCHE KOMM. GES. March 23, 1966, No. 12807/66. Heading B7H. [Also in Division F1] A transmission unit for a motor vehicle having a transversely mounted internal combustion engine 1 includes a change-speed transmission 2 and an axle gear unit 3 for driving the road wheels 4 connected by means including a continuously meshing gear with a driving gear-wheel 19 and a driven gear-wheel 20 having their axes of rotation at an angle α to each other of substantially less than 90 degrees, the teeth of the gears being of worm drive type with gliding tooth engagement. The axis of the engine may be inclined or alternatively the engine may be mounted with its transmission shaft parallel to the axis of the road wheels and the axle gear unit inclined, the latter being connected to the road wheels by double-jointed drive shafts (21<SP>1</SP>).

Title: Tape recorder changeover mechanism
IPC: H04M1/65
Filed: 1973-03-16
Abstract: 1420415 Double tape-decks; telephone answering devices PIONEER ELECTRONIC CORP 16 March 1973 [21 March 1972] 12827/73 Heading G5R Two magnetic record tapes are operated either sequentially or simultaneously at will, one tape playing back and the other recording either subsequently or simultaneously. As shown, in a telephone answering device a prerecorded message is played back from a first tape T1 in a cartridge 1 in response to an incoming call. With a manually-operable lever 8 in the position shown in Fig. 1, leftward movement, Fig. 2, of a plunger 6 on detection by contacts 22 of the end of the message stops the tape T1 by disengaging its pinch roller 17 and engages a second pinch roller 311 to drive a second tape T2 in a cassette 2 for recording incoming messages by means of a head 3<SP>1</SP>. Alternatively, the lever 8 may be set to the position shown in Fig. 3 in which pawl 13 is out of the path of lug a so that leftward movement of the plunger 6, which is arranged to take place on the arrival of an incoming call, does not stop the first tape T1 and the two tapes are driven simultaneously, Fig. 4 (not shown), enabling a caller to record a message on the second tape T2 without waiting for the complete playback of the prerecorded tape T1.

Title: Process for the stereospecific polymerisation of butadiene
Inventor: DAUBY ROBERT
IPC: C08F36/06
Filed: 1964-03-26
Abstract: Trans-1,4-polybutadiene is prepared by polymerizing 1,3-butadiene in aqueous emulsion in the presence of a rhodium salt and 1,3-cyclohexadiene, the cyclohexadiene being present in a proportion of at least 3 mols. per mol. of rhodium salt. Rhodium salts specified are the trichloride, trinitrate, ammonium chlororhodate and sodium chlororodate.  As emulsifier, those of the anionic type are preferred, for example an aryl or alkylaryl sulphonate, e.g. sodium dodecylbenzene sulphonate, or a sulphonated alcohol.  The butadiene may be used in admixture with saturated and olefinic hydrocarbons, e.g. butane and butenes, without affecting the nature of the polybutadiene product, i.e. the butadiene is selectively polymerized.

Title: Improvements in tuning systems for radio apparatus
IPC: H03J7/16
Filed: 1935-05-01
Abstract: 460,987. Valve circuits for wireless reception. HENRY, G. May 1, 1935, Nos. 12980 and 12981. Void. Convention dates, May 2, 1934 and April 2, 1935. [Class 40 (v)] The tuning elements of a manually-controlled radio receiver are automatically kept in exact tune to the desired frequency by an error detector embodying circuits resonant 'above and below the desired frequency and acting in opposition on a regulating member. In Fig. 1 the output from the intermediate frequency amplifier (or mixing valve) IF is applied to a pair of pentodes A<1> B<1> through couplings A, B tuned respectively 5kc. above and below the intermediate frequency, the negative bias of the control grids from resistances r decreasing with signal input, The output from A<1> and Bl is applied to power triodes A<111> B<111>, in the anode circuits of which are connected an opposing pair of coils of a milliammeter mounted on the spindle M which also carries the rotors of a pair of trimming condensers CVA-CVH which are connected in parallel with the receiver tuning condensers. Any departure from the precise mid-frequency of the two systems A, B, will upset the balance and current will flow through one of the milliammeter coils to cause movement of the trimming condensers in such sense as to restore the balance. A single coil may be used for the milliammeter device ; in this case parallelfeed connections are used. In Fig. 4, one of the IF transformers may be coupled as at PP to a pair of rectifiers D<1>, D<2>, the detector input circuits being tuned one above the other below the desired intermediate frequency. The outputs from the detectors are applied in opposition to the coil of a galvanometer G. Movement of this coil in either direction causes corresponding variation of tuning to restore balance through contacts C<1>, C<2> and relays RL RL<2> which actuate a motor driving tuning condensers CV.
