Title: An improved walking doll
Inventor: CECCON ENRICO
IPC: A63H11/18
Filed: 1969-05-16
Abstract: 1,256,430. Walking doll. E. CECCON. 16 May, 1969 [28 May, 1968; 25 Feb., 1969], No. 24968/69. Heading A6S. The mechanism for a walking doll consists of a three arm lever 11 pivoted about a pin 9, the axis of which is parallel to the walking direction of the doll, the upper lever arm or effort arm being caused by a driving means, e.g. an electric motor 4, to swing about a vertical axis A-A passing through the pivot axis of said lever, while the other two arms of the lever are symmetrically inclined but in opposite direction with respect to the effort arm so as to project outwards and downwards as the axis of the effort arm is vertical, each of said lower arms being fixedly connected to a supporting member 13, preferably conical, on which is frictionally hinged a concentric connecting device 16 made integral with the upper part of each leg 3. The inner end of each supporting member 13 projects outwards with an annular flange 15 constituting a bearing surface for a similar flange 17, forming part of the connecting device 16, and which is pressed against flange 15 by means of a spring 18 to provide the said friction effect. A spring-disengageable locking means is also provided and comprises a recess 19 arranged in one of the flanges and a projection 20 in the other, which locking means is associated with the spring 18 and becomes operative as the doll stands up. The foot 3a of the leg comprises a plate 24 to which a parallel, identically shaped plate 25 is connected in a spaced relationship by means of a plurality of pins 26 sliding in guide holes provided in the upper plate and set substantially at right angles to said plates which are spaced apart from each other by means of springs 27. The mechanism causes the legs of the doll to swing up and down in such a manner that as one of the legs moves upward, the whole weight of the doll acts on the foot of the other leg now resting on the floor at a point which constitutes the pivot point about which the doll is caused to rotate so as to put the raised leg forward. The upper part of the doll as well as the legs is bent backwards according to a curved line, the most forward part of which is the part of the doll trunk wherein the walking mechanism is located so that as the weight of the doll rests on the floor, the centre of gravity of the doll is vertically over the forward part of the foot on the floor.

Title: Improvements in or relating to circuit arrangements composed of transistor stages
Inventor: SNIJDERS ANTONIE
IPC: H03K19/084
Filed: 1957-08-08
Abstract: 864,794. Transistor switching circuits. DE STAAT DER NEDERLANDEN. Aug. 8, 1957, No. 25027/57. Class 40(6) Each stage of a multistage switching circuits (Fig. 3) comprises a transistor T3 having its emitter connected to a point of constant potential, its collector connected to an output terminal and its base connected to a point on a potential divider connected between the input terminal 11 and one supply terminal, the input terminal also being connected through a resistor to the other supply terminal. Each stage feeds a number of similar stages through a rectifier arranged to isolate the input circuits one from another and either the value of the resistors connected between the input terminals and the other supply terminal is such that the driving stage transistor remains saturated when all the associated driven transistors are in circuit or a common resistor is used in place of the several resistors and is given a value such that the driving transistor remains saturated when all the associated driven transistors are in circuit. In Fig. 3 two stages T3, T4 are cross coupled to form a bistable circuit and each feeds one or more similar stages through isolating rectifiers. Where a common resistor is used to connect the input terminals to the second supply current source the rectifiers are reversely connected as compared with those shown in Fig. 3 (Fig. 4, not shown). The input terminal of a stage may be connected through appropriately poled rectifiers to a number of driving stages and may also be connected to a number of driven stages (Fig. 5, not shown). In Fig. 6 the output of one stage T30 is shown connected through a series of rectifiers with appropriate biasing to the input of a second stage T31. Additional driving and driven stages may be connected at any of the points k5, k6 and k7 and by adding additional rectifier and biasing circuits additional "k" points may be provided. The couplings between the stages may be such that where two or more driving stages feed one driven stage the driven stage is controlled either by the driving stage which is conducting or by the driving stage which is not conducting.

Title: Method of dehydrating gypsum
IPC: C04B11/028
Filed: 1958-08-05
Abstract: Gypsum is calcined by first heating in a closed rotating chamber provided with indirect heating means, and then calcining in the same chamber whilst gradually decreasing the steam pressure to atmospheric.  The apparatus consists of a closed chamber having internal members in indirect heat exchange with the solid, which members are of a form such as to sub-divide the mass of solid to be dehydrated into smaller portions heated at both sides thereof.  As shown in Figs. 1 and 2, a drum 7 is supported by and rotates about an axial pipe 21 which rests on rollers 5 carried by supports 2.  Inside the drum the tube 21 <PICT:0866126/III/1> <PICT:0866126/III/2> carries a concertina like arrangement of annular dished members 26 peripherally joined at 28 to form a series of chambers communicating with the interior of pipe 21 through perforations 25.  A gas burner 22 delivers a blast of hot combustion product into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26.  The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the container, by means of pipes 30. Tubes 8 are provided with exhaust passages 31 having a terminal elbow 32 whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhaust 31 in contact with the exterior of the drum 6. Gypsum is fed to the drum through removal closures such as 11 and the steam formed by dehydration is vented through valves 13.  As shown in Fig. 2 the valve 13 is operated by a lever 16 carrying a roller 18. The latter abuts a valve operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.  In operation for the dehydration of gypsum, gypsum pieces having a maximum dimension of an inch is fed to the drum in an amount sufficient to permit relative movement between the pieces of gypsum on rotation.  The steam tight closures 11 are sealed and the drum rotated.  The pressure rises to about 35 p.s.i.g. as the gypsum becomes heated and thereafter rises to about 40 p.s.i.g. as dehydration commences.  The cam 19 is thereupon adjusted to release the steam pressure, and as dehydration proceeds the valve 13 is opened progressively wider until at the end it is wide open and the pressure has dropped to atmospheric.  The drum may be preheated before introducing gypsum to a temperature of about 300 DEG F. During dehydration the temperature remains at about 250 and may be raised to about 270 DEG F. at the end of the operation.

Title: Improvements in or relating to the precise measurements of linear dimensions
IPC: G01B11/00
Filed: 1960-07-19
Abstract: 919,016. Automatic control of linear dimensions. SICK, E. July 19, 1960 [July 20, 1959], No. 25091/60. Class 38 (4). [Also in Group XL (b)] In a photo-electric device for linear measurement a light beam partially obscured by the measured object is compared in intensity with a comparison beam partially obscured by a comparison object. Both beams are directed from a common source on to a photo-electric element on the same side of the objects as the source by means on the other side of the said objects that reflect the light back along the incident paths together with a movable reflecting means. In an embodiment for measuring and controlling the gap between the rollers of a strip mill, Fig. 1, light from a source 3 passes through a semipermeable mirror 9 and is alternately reflected and transmitted along two paths by a halfmirrored, half-transparent rotating disc 11. One path contains the gap between rollers 1 and 2 to be measured and a reflector 8 to return the light along the same path for it to be reflected by the semi-permeable mirror 9 on to a photocell 10, whilst the other contains a gap capable of adjustment by a micrometer screw 14<SP>1</SP> between roller sections 13 and 14 of shape and surface similar to 1 and 2, the light also being reflected back along the same path on to the photo-cell 10. When the gaps differ the intensities of the beams differ so that the envelope of the output voltage from the photo-cell, Fig. 4, varies to produce after filtration a voltage waveform such as Fig. 5, the amplitude and phase of which depends on the relative sizes of the gaps. This voltage controls (via a phase-sensitive circuit adjusting the means 18 of Fig. 1) the size of the measured gap until it matches that of the comparison gap. Another embodiment for controlling the machining of a production part until a predetermined dimension is reached is also described (Fig. 7, not shown).
