Title: Device for automatically evaluating diagrams
IPC: G06K11/00
Filed: 1972-01-20
Abstract: 1365198 Analyzing bar and zig-zag diagrams KIENZLE APPARATE GmbH 20 Jan 1972 [30 Jan 1971] 2862/72 Headings G4D D7X D6Y D6C1 D6C2 D6L and DID9E Apparatus for the automatic analysis of bar diagrams produced on a circular track which is rotated once in 24 hours during rec., the diagrams having one of two widths indicative of whether a vehicle engine is in operation under load or no load conditions and of a length indicative of the time during which such conditions exist, and for the analysis of zig-zag distance diagrams, the number of climaxes of which is indicative of a total distance travelled by the vehicle is adapted such that results read from the record may be accurately correlated with the times at which the recordings were made. As shown, a carrier table T bearing a set of such diagrams on a disc 1 is rotated by a drive 2 which also operates a pulse generator 3 which thereby produces a fixed number of output pulses for each unit time during which the recording was made. The pulses are taken to a gate 3a which is opened when a cam N causes a switch to be thrown which indicates that the disc is then at a zero mark with respect to a photo-electric sensing station comprising a line of 8 photo-diodes A-AK which sense one track of the disc 1 in a direction normal to the direction of drive of the track. When sensing a bar diagram, outputs L 1 -L 8  are taken to two logic circuits 7, 10 each comprising an array of NAND gates. If a narrow bar diagram is present, illumination of the cells A-AK is such that the circuit 7 opens AND gate 9 to allow pulses from the generator 3 to be counted at 4. When a wide bar is present, the circuit 10 enables gate 12 to pass the pulses to counter 5, the absence of a bar (engine not running) causes gate 13 to be enabled and the pulses are counted at 6. Results are printed out by a device 14. For the analysis of a zig-zag diagram, the sensors are moved to the appropriate track and a circuit 15 enabled which comprises 4 monostables having inputs connected to 4 of the photo-cells A-AK and having outputs connected to corresponding flip-flops. Additional logic circuitry is included and an output pulse on line 23 is produced for every complete sequence of 4 input pulses on the inputs in turn as the zig-zag is moved, each such sequence being indicative of a unit of distance between adjacent climaxes. These pulses are passed to a generator S 5  where a particular number, e.g. 5, of pulses are produced and counted at 16 so that this represents the distance in kms. Partial ramps at the ends of the diagram are allowed for and pulses are produced on line 24 to a second generator S 2  where, e.g., 2 pulses are inserted into the counter.

Title: A process for the recovery and utilization of gases which escape from carbon disulphide works
IPC: C01B17/16
Filed: 1937-02-01
Abstract: In a process for the recovery and utilization of gases which escape in the manufacture of carbon disulphide, these gases are energetically cooled (say to 40--60 DEG  C. below zero) so as to condense and separate the carbon disulphide, the residual sulphuretted hydrogen, after being washed, being sufficiently pure to be directly utilized for the preparation of any sulphide.  An example is given in which the carbon disulphide content in the gases is reduced by cooling to -55 DEG  C. from 25 to 0,3 per cent, and by successive washing with barium sulphide solution all the carbon dioxide is fixed and the carbon oxysulphide is decomposed into sulphuretted hydrogen.

Title: Improvements in or relating to machines for staking, softening and similarly treating hides, skins, leather and the like
IPC: C14B1/40
Filed: 1937-02-02
Abstract: 489,711. Leather-working machines. TURNER TANNING MACHINERY CO., Ltd., and SCHETTLER, G. A Feb. 2, 1937, No. 3035 [Class 76] In a machine for staking or softening leather of the type comprising a pair of jaws, which are reciprocated and moved to and from each other synchronously with their reciprocations, so as to stretch and bend the leather over tools carried by the jaws, means are provided whereby the relative movements of the jaws can be gradually nullified and gradually restored during the reciprocation. In the machine shown in Fig. 1, staking tools 13a, 14a, are mounted on arms 13, 14 pivoted at 23, 24 on a crosshead 16 supported on parallel swinging arms 32, 33 pivoted at 34, 35 in the frame 1. The reciprocatory and opening and closing movements of the arms 13, 14 are effected by means of a connecting rod 11 mounted on a crank pin 8 driven by a pulley 9 and pivoted at 15 to links 17 pivoted at 18 to the crosshead. The connecting rod 11 carries in fixed relation a cam 12 which bears on a roller 31 mounted on the arm 14. The cranked ends of the arms 13, 14 are connected by a link 25 and an adjustable spring 28 is provided to keep the roller 31 in contact with the cam. The links 17 are connected by a link 20 to a treadle 22 by the operation of which the links 17 are moved about their pivot 18 and the pivot point 15 of the link 11 is raised so that the cam comes into contact with the roller 31 and effects the opening and closing of the arms 13, 14. When the treadle is released the arm 14 drops into contact with a stop 30 and the tool then reciprocates without contact with the work carried by the divided tables 58. The link 20 is normally parallel to the links 32, 33, and the pin 15 in its movement follows the same general arcuate path as the crosshead and the tools 13a, 14a describe a parallel sided path. The lower end of the link 20 is however horizontally adjustable in the treadle and when so adjusted to one side or the other the path of the pin 15 is inclined somewhat to the path of the crosshead and the tools describe paths slightly tapered to one end or the other of their stroke. In a modified construction, Fig. 3, the crosshead moves in slides 60, and the links 17 are supported by a roller running on a track 62, which can be moved vertically by mechanism 63-67 and also tilted. The movement of the treadle is limited by a stop 53 against which the treadle may be pressed by the operator, but an auxiliary treadle 22a may be provided on the treadle shaft and when this is employed a yielding pressure is applied to the work due to the torsional resilience of the shaft. The work is clamped during the working stroke by an arm 38 operated synchronously with the staking mechanism by means which may be as described in Specification 489,748. Staking tools of the construction shown in Fig. 5 may be mounted on the bars 13, 14 comprising knives 73, 74, 75 and rollers 69, 70.

Abstract: 113,621. Ammann, T. Feb. 21, 1917, [Convention date]. Suitches, quick-action.-A one-way turn switch with ratchet means to permit of free reverse rotation consists, in the form shown in Figs. 1, 2, and 5, of a turn member 6 with an upper part which projects through the casing 7 and constitutes the handle 8, and a lower flanged part 9 which is formed with a conical recess to take a bearing on a metallic cap 4 covering a conical projection 3 on the base.- The upper surface of the flanged part is conical as shown in Fig. 1, and is formed with ratchet teeth engaged by similar teeth on the similarly shaped under surface of the metallic contact-ring 11, Fig. 2, the upper surface of which is toothed. The conical seating surfaces ensure that the contact-ring maintains a central position notwithstanding that it is capable of longitudinal play. The ring is pressed into engagement with the twin member by contact springs 13 - - 16, Fig. 5, each held by a single screw in recesses 17 in the base, and extending over, and into engagement with, the upper surface of the contact ring, one on more upper teeth of which is provided with an insulating-covering. Clockwise rotation of the handle drives the contact ring and alternately brings the conducting and non-conducting teeth of the ring into engagement with the spring contacts. Reverse rotation lifts the contact ring against the action of the spring-contacts but does not rotate it. Constructions are also described in which the upper part of the casing constitutes the bearing surface and the contact springs and contact ring are located below the bearing surface.

Title: Improvements in or relating to gearing for steering mechanically propelled vehicles and for other purposes
IPC: B62D3/06
Filed: 1937-02-03
Abstract: 489,672. Cam mechanism. BISHOP, R. Feb. 3, 1937, No. 3130. [Class 80 (iii)] In gearing particularly applicable for the steering of automobiles of the kind comprising a cam engaged by a follower on a rocker arm mounted on a rocker shaft as described for example in Specifications 223,963, [Class 83 (iii)], 342,770, and 422,346, the effective part of the follower is of elongated form presenting an extended bearing surface to the cam. Further, the pitch of the cam is made slower at each of its ends than in the middle and the pitch is made different towards the two ends to ensure that equal movements of the steering wheel produce substantially equal movements of the road wheels on both locks. The gearing is generally similar to that described in Specification 422,346, the groove of the cam 1 being engaged by an elongated follower 2 whose pivot 3 is mounted in a bearing 4 in the end of the rocker arm 5 on a rocker shaft 6. Integral with the pivot 3 is a crank-disc 3<1> and crank pin 7 on which is mounted a roller 8 guided in an arcuate slot 9 in a plate 10 to keep the follower parallel with the cam groove. Examples are given of the pitch differences of the cam and the corresponding gear ratios. The follower may be modified in that the pivot 3 may have a diametral slot 19, Figs. 3, 4, in which is mounted on a stud 22 a rolling follower consisting of a pair of discs 23 with bevelled outor faces 24 and grooves on their inner faces to form races for balls 25 or, in a modification, rollers. The discs are freely rotatable on a bush 21 which holds the parts 20 at the correct distance to permit free running of the discs. The projecting parts 27, Fig. 3, of the discs engage the cam.
Patent GB-371946-A (GB)
Title: Improvements in or relating to the manufacture of aliphatic anhydrides
IPC: C07C51/56
Filed: 1931-01-31
Abstract: Carbonyl chloride for use in the production of acid anhydrides from carboxylic acids is obtained by passing a mixture of carbon monoxide and chlorine over charcoal.  The carbonyl chloride may be obtained and used in the nascent state by passing a mixture of the vapour of the carboxylic acid, carbon monoxide, and chlorine over charcoal or silica gel at 200-350 DEG  C.ALSO:The anhydrides of aliphatic acids are obtained by causing the vapours of the acids to react with carbonyl chloride.  The reaction is greatly accelerated by elevated temperatures, such as 150-350 DEG  C.  The reaction vessel may be filled with porous or absorbent bodies such as charcoal or silica gel.  To avoid the formation of considerable quantities of the organic acid chloride, at least two molecules of acid should be used per molecule of phosgene.  The vapours issuing from the reaction vessel may be condensed, and the crude anhydride then purified by fractional distillation, or the anhydride may first be treated with anhydrous sodium acetate or acetate to remove acetyl chloride and hydrogen chloride.  The phosgene may be produced by passing a mixture of chlorine and carbon monoxide over a catalyst such as charcoal, in which case the product is then treated with the acid vapour.  Or the phosgene may be employed in a nascent state, e.g. by passing a mixture of chlorine, carbon monoxide and acetic acid vapour over silica gel or active charcoal at a temperature between 200 DEG  and 350 DEG  C.  The invention may be applied to the production of acetic anhydride or the anhydrides of higher aliphatic acids such as propionic or butyric acids.  In the example, which illustrates the production of acetic anhydride, it is indicated that the crude vaporous product is cooled in a condenser, and the vapours escaping condensation are scrubbed successively with acetic acid and benzene to recover acetyl chloride, and thereafter with water to recover hydrogen chloride; the crude anhydride collected in the condenser may be subjected to any convenient treatment to remove the hydrogen and acetyl chlorides present therein, and to separate as far as possible the anhydride from the unchanged acetic acid contained therein, e.g. it is first heated under reflux and thereafter subjected to fractional distillation; the acetic acid used for scrubbing may be purified in a similar way.
