Title: Apparatus for transferring sheets in exact register in sheet-fed rotary printing presses
IPC: B41F21/10
Filed: 1976-01-02
Abstract: 1487521 Registering sheets KOENIG & BAUER AG 2 Jan 1976 [17 April 1975] 00055/76 Heading B8R Sheets are transferred from an impression cylinder 3, Fig. 1, to an impression cylinder 7, Figs. 1 and 5, of a rotary printing machine by way of a reception drum 4, a transfer drum 5 and a transfer register drum 7, all of the cylinders and drums 3-7 being of a size to hold two sheets simultaneously and therefore each being provided with two rows of grippers 3.1, 3.2 to 7.1, 7.2. The drums 5, 6 and cylinder 7 are each provided with two toothed register pieces 5.3, 5.4, 6.3, 6.4, 7.3, 7.4, each peripherally and radially adjustable. The train of drums and cylinders is driven by meshed gear wheels. The drum 6 is peripherally adjustable about its drive shaft 6.5, being coupled to its driver member 6.9 by resilient couplings. The arrangement is such that as a sheet is transferred from drum 5 to drum 6 or from drum 6 to cylinder 7, the register pieces concerned are in engagement with others to overcome the effect of gear tooth backlash and the resulting mis-registration. A drive wheel 10 acts as a flywheel to prevent variations in velocity in the system.

Title: Device and method for determining positional information of bar code scanner
Inventor: BLANFORD DENIS MICHAEL
IPC: G06K7/10
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a system for synchronizing the angular position of a rotary optical assembly in a bar code scanner. SOLUTION: The rotary optical assembly is rotated by a motor for generating the prescribed number of pulses at every rotation. These pulses are generated at an equal interval so that each pulse indicates the rotational angle of the motor. These pulses are continuously monitored and counted up. A synchronizing label 410 is arranged in a scanner 10 so that light directed through the assembly located at a certain specific angular position is projected to the label 410, reflected by the label 410 and returned to the assembly. Therefor the initial angular position of the assembly is defined. Once the initial angular position is defined, timing is continuously monitored and pulses are continuously monitored and counted up.  When a noticed event such as bar code scanning occurs, the count value of pulses is evaluated and processed and the angular position of the assembly is determined based on the initial position defined by synchronization.

Patent DK-64586-A (DK)
Inventor: KRISTENSEN KURT
IPC: A23G9/26
Filed: 1986-02-11
Abstract: When producing popsicles by the frozen tunnel method, the objects to be frozen are placed on support sheets 10 on an endless transport chain 4, which takes the objects through a freezing room 2, from which the transport chain sticks out in a short narrow loop with an ingoing stretch 6 and an exit stretch 8. In practice, the corresponding elements for putting down or taking up from the sheets must work from the outside of the particular stretch, and when the production is switched from larger objects to smaller objects in the form of ice lollies it is almost always necessary for the lollies 16 to stick out beyond the side edge of the support sheet 10, in order to have the necessary room for the required gripping elements. It is thus difficult to utilize the space on the support sheets, which viewing from the outer edge is situated behind the outer edge segment of the relatively small objects 14. It has been proposed to use horizontal turnable support sheets in order to also utilize the opposite edge region, but this is a costly and inconvenient solution. The invention proposes that, when switching production between objects of different size, i.e., with possibility of placement in more or fewer rows, one undertakes such a modification of the support sheets 10 that they have mutually displaced support sheet levels 26, 28; 38, corresponding to the actual number of rows, thereby producing said required space beyond the outer edge of each of the support sheet levels. In this way, the space on the support sheets can be utilized effectively when simple grasping elements are arranged to selectively interact with the objects along the particular different levels of support surfaces. <IMAGE>

IPC: G10K11/34
Filed: 1972-01-03
Abstract: 1360901 Correlators RAYTHEON CO 3 Jan 1972 [1 Feb 1971] 175/72 Heading G4A [Also in Division H4] In a sonar system (see Division H4) a replica of the transmitted wave train is cross-correlated digitally with the subsequently received echo signal wave train as follows. Both wave trains pass (in turn) through amplifier 102 and are frequency-translated at 104 to a convenient 3À5 kHz signal which is clipped at 108 and then sampled at a 20 kHz rate at 118 to give a series of single-bit binary samples. At the time of transmission a gate 122 opens and the 1032 samples of the replica wave-train are entered into a 1032 stage shift register 130 which is then switched to act as a recirculating loop memory. The sampler 118 output is entered also into a 1031 stage shift register 136 which is then connected as a recirculating loop memory. The recirculation period of the memory is just less than the interval between samples from 118, so that the register 136 contents can be up-dated by one sample every recirculation period. This, together with the difference in storage capacity of registers 130 and 136, ensures that the contents of one register precess with respect to the contents of the other. The data bits at the two register outputs are compared by a coincidence detector 126 whose binary output is smoothed by integrator 128 to give an amplitude-modulated substantially sinusoidal 3À5 kHz signal in which the amplitude represents the degree of correlation between the two register contents.

Abstract: The invention comprises 6-hydroxy (and acetoxy) - 3,5 - cyclopregn - 16 - en - 20 - one of the general formula <FORM:0801794/IV (b)/1> wherein R represents hydrogen or the acetoxy group, and a process for the preparation of 6-hydroxy-3 : 5-cyclopregnan-20-one by hydrolysing an aryl sulphonate of 16-dehydropregnenolone and catalytically hydrogenating the resulting 6 - hydroxy - 3 : 5 - cyclopregn - 16 - en 20-one.  The hydrolysis may be carried out under weakly alkaline conditions and in an aqueous organic solvent medium, e.g. by heating with aqueous acetone, aqueous methyl ethyl ketone or aqueous dioxan in the presence of potassium acetate.  The hydrogenation step may be effected in an organic or aqueous organic solvent mixture and in the absence of a mineral acid.  A suitable catalyst for the hydrogenation step is Raney nickel or palladium on calcium carbonate.  The above process may be modified in that the 6-hydroxy-3 : 5-cyclopregn-16-en-20-one is acetylated, and the 6-acetyl derivative is hydrogenated as above to form 6-acetoxy-3 : 5-cyclopregnan-20-one which is then hydrolysed to form the 6-hydroxy-3 : 5-cyclopregnan-20-one. Suitable arylsulphonates of 16-dehydropregnenolone are benzene sulphonate and toluene p-sulphonate of 16-dehydropregnenolone.  A number of detailed examples are given.  Starting compounds.  16-Dehydropregnenolone benzenesulphonate is prepared by reacting 16-dehydropregnenolone and benzene sulphonyl chloride in the presence of pyridine. 16-Dehydropregnenolone toluene-p-sulphonate is prepared by a similar method.

When the housing is in the lowered position it cooperates with the belt to form a sealed chamber enclosing two bags which have been fed side by side by the belt into position with their mouths beneath two electrically-heated sealing bars 15 mounted for vertical movement within the housing and operable through rack and pinion gearing 17-19 by air cylinders 21. The chamber is evacuated through a pipe 14 controlled by a valve 13 and the cylinders 21 are then actuated to cause the bars 15 to descend and seal the mouths of the bags. The belt is moved by a pulley which is driven intermittently through a clutch operated by a further air cylinder, see Fig. 4 (not shown). The valve 13 and the various air cylinders are controlled by cam-operated valves so that they are actuated in synchronism. A further cam-operated valve may control the admission of an inert gas to the housing 3. In a second form, Figs. 11-14 (not shown) the valve 13 is controlled automatically by the movements of the housing 3, and the movements of the bars 15 are controlled by pressure-sensitive switches within the housing.

Abstract: 549,847. Directive wireless signalling. LEAR AVIA, Inc. Jan. 11, 1941, No. 415. Convention date, Jan. 11, 1940. [Class 40 (v)] An aircraft navigational instrument comprises a directional compass associated with a radio compass both having adjustable course indexes for facilitating aerial navigation. The general arrangement is shown in Fig. 1 in which an aerial 3 is maintained in a null position as regards a radio station by means of a reversible motor 6 under the control of receiving apparatus 1 in the manner described in Specification 550,131. The position of the aerial 3 is conveyed by flexible shafts 12, 14 to indicator 13 and to pointer 20, 20<1> on a rotatable transparent disc of instrument 15. An index 18 is carried by a toothed disc 26 frictionally mounted on a disc 16 movable by a directional gyroscope or magnetic compass. The two discs are viewed through a transparent cover 31 on which are inscribed a lubber line 32 and representation of an aeroplane 34. Disc 26 is set relatively to disc 16 by holding disc 26 stationary by depression of knob 19 and finger 27 and then turning disc 26 by means of knob 17. For simple homing flight the pointer 20 is kept in line with line 32 and on passing over the radio station the pointer. 20 suddenly turns through 180 degrees. For flying a straight course to a radio station, the course is set on the compass and the plane is flown to keep pointer 20 and index 18 in line. In this case the deviation of these indications from line 32 shows the attitude of the plane due to cross wind. Various characteristic indications and commonly required manoeuvres are described. Specification 523,093 also is referred to.

[Also in Division G1] A monostable multivibrator 22, particularly for controlling the duration of fuel injection in an I.C. engine, is provided with signals from a circuit 50, the frequency of signals being the same as that of the trigger pulses produced by contact breaker 45, but the waveform of the signals from 50 varying with frequency so that the duration of pulses from the monostable multivibrator 22 varies in a predetermined manner with frequency. In an I.C. engine 10 the duration of pulses of injected fuel is controlled by a monostable multivibrator 22 in such a way that the duration of each pulse increases as the vacuum in the inlet manifold 12 increases, and also changes with engine speed, reaching a maximum at 3600 r.p.m. The speeddependent control of pulse duration is made effective at the end of each pulse by signals supplied from a circuit 50 so that the maximum pulse duration occurs at the same speed for any vacuum pressure. The monostable multivibrator 22 is triggered by pulses obtained from a cam-shaft-driven contact breaker 43, the duration of pulses from 22 being primarily dependent on the inductance of winding 31 of a transformer 26. The pulses from 22 are amplified at 49 and fed via transistors 20 or 21 to electromagnetic fuel injection valves 13. A movable iron core on transformer 26 is coupled to a vacuum box 28 so that the pulse duration increases with vacuum. Two further monostable multivibrators 51, 52 are sequentially triggered by the offset of each pulse from 22 and respectively charge and discharge capacitor 67 so that the resulting voltage, when fed to the base of transistor 23 controls the duration of pulses from 22 in such a way that the duration is a maximum at 3600 r.p.m. In Figs. 7, 8 (not shown) the monostable circuits 51, 52 are replaced by pulse shortening circuits each comprising a capacitor in the base circuit of a transistor.
