[Also in Group XXXII] An automotive vehicle supported o n traction wheels is provided with auxiliary traction means in the form of a hollow roller or drum interposed between t h e traction wheels which are driven by means located within the roller or drum. Bearing sleeves 23 and 24 are carried by the vehicle frame members 27 and 28, and 25 and 26, respectively, the auxiliary wheel or drum 33, which may have grippers 34, being carried on the sleeves by a bearing 32a and a gear casing 14, to which it is attached b y a flange 32. mounted on bearings 30 and 31. Driving shafts 12 and 13, to which are attached driving pinions 16 and 15, are carried in the bearing sleeves 24 and 23 by bearings 20 and 22, the outer parts of the bearing sleeves being connected to the driving wheels 10 and 11. Planet pinions 17 and 18 are carried by the casing 14 and mesh with the pinions 15 and 16. The drum 33 is provided with an internal gear portion 35 which is engaged by a driving pinion 37 of an electric or hydraulic motor 38 suspended at 39 from the sleeve 23, and the electric supply cables 41, 42, or pressure oil supply lines, for which are led through the frame 27 and sleeve 23, the road wheels being driven by the motor 38 through the gears 37, 35, casing 33 and 34, and pinions 17, 18, 15 and 16 which form a differential gear. When the wheels 10 and 11 sink into soft ground or the tyres thereof are deflated, the wheel or drum 34 becomes the load bearing and driving wheel. The motor 38 may be an internal combustion engine. Power for an electric motor may be supplied by a diesel-electric unit carried by the vehicle. A low pressure pneumatic tyre, or tyre of solid rubber construction, may be carried by the drum 33.

Abstract: 623,167. Electromagnetic, relays. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. (Union Switch & Signal Co.). April 24, 1947, No. 10934. [Class 38(v)] A polarized relay has two armatures 7a, 7b which are in the released position when the coil 6 is de-energized ; energization of the coil in one direction picks up armature 7a and locks armature 7b; energization of the coil in the other direction picks up armature 7b and locks 'armature 7a. In the form shown, there are two cores 3a, 3b passing through the coil 6 and having pole pieces 4a, 5a and 4b, 5b respectively. Two permanent magnets 15a, 15b are arranged with their upper poles N. S secured to the pole pieces 2a, 2b respectively, their lower poles acting as supports for the armatures 7a, 7b in their released position and tending to hold them there. Current through the coil 6 causes one armature to rise and a projection 18a or 18b on it tilts a centrally-pivoted lever 16 so as to prevent movement of the other armature. In a modification, the two armatures are pivoted at opposite ends and co-operate with a single pair of poles fixed to a single core, and in a further modification, Fig. 3, the armatures 7a, 7b co-operate with a pair of coils and are interlocked by means of arms 31, 32 provided with stop pins 31a, 32a.

Title: Improvements in or relating to electric pulse-width modulators
IPC: H03K4/06
Filed: 1956-04-11
Abstract: 802,028. Pulse modulation circuits; triangular wave generating circuits. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 11, 1956 [April 19, 1955], No. 11005/56. Classes 40 (5) and 40 (6). In a pulse width modulator two transistors are connected in series, a triangular wave voltage being applied between the base and emitter of one and a modulating voltage between the base and emitter of the other, and an output load being connected between the emitter and collector of one of the transistors. In one embodiment, P-N-P junction transistors 1 and 2 are connected in series, the collector 5 of transistor 2 and emitter 19 of transistor 1 being connected to a D.C. source 13. A high-impedance load 11, connected between emitter 19 and collector 17 of transistor 1 is an amplifier requiring a rectangular wave voltage for actuation. A modulating voltage source 3 connected between base 7 and emitter 9 supplies a D.C. voltage, or an A.C. voltage of a frequency low with respect to that of sawtooth generator 18, which comprises a transformer 37 with two pairs of rectifiers, each pair connected for fullwave operation. The output voltages of the rectifiers are of opposite polarity, and are mixed in resistive mixer 20 and 21 to give an inverted full-wave sinusoid, the known characteristics .of a transistor correcting the shape to that of a triangular sawtooth. When the output voltage of generator 18 is applied to the base of transistor 1 current flows through both transistors until the output voltage of modulator 3 reaches a limiting magnitude, at which moment the transistor 2 begins limiting. Thus the duration of the voltage pulse across load 11 depends upon the magnitude of the modulator output voltage, the output waveform across the load being a sawtooth with a clipped flat top. In a further embodiment, Fig. 4 (not shown), the magnitude of pulse width modulation is determined by the sum of the output voltages of a number of modulators in parallel.

Title: Process for the production of pure monomeric formaldehyde
Inventor: KAUFHOLD ROBERT
IPC: C07C45/78
Filed: 1963-03-20
Abstract: Pure monomeric formaldehyde is produced by washing gaseous formaldehyde with semiformed solutions at a temperature of from - 10 DEG  C. to + 80 DEG  C., the semi-formal solution used as washing liquid moving in a closed circuit, the adsorbed impurities being separated from the washing liquid by known methods, the alcoholic component of the semi-formals consisting of alcohols with a boiling-point above 100 DEG  C., decomposing the bulk of the semi-formal solution first used as a washing solution by heat and conveying the resulting formaldehyde gas to the semi-formal washing liquid where it is washed to yield pure monomeric formaldehyde, mixing the solution poor in formaldehyde remaining after the decomposition with polluted aqueous formaldehyde solutions and/or formaldehyde alcohol solutions in which the alcohol component has a boiling-point of over 100 DEG  C., separating the water from the mixture and adding the resulting semi-formal solution to that part of the washing liquid which has not been thermally decomposed and which is caused to move in a closed circuit.  In a modification, the part of the washing liquid which has been thermally decomposed and mixed with aqueous formaldehyde solutions and/or formaldehyde alcohol solutions in which the alcohol has a boiling-point above 100 DEG  C. is added to the non-decomposed part of the semi-formal solution, the absorbed impurities and the water being mainly removed from the resulting mixture by distillation at reduced pressure. The alcoholic component of the semi-formal solutions preferably consists of multivalent alcohols having fewer than 5 carbon atoms.  Examples are given.
