Abstract: In a machine for automatically mounting sliders 11 on closure strips 1 having interengageable profiles 2, the sliders are fed in succession into respective locations 14 provided at the periphery of a rotor 9 set in rotation by a step-by-step drive motor. Between the periphery of the rotor and an arcuate stator 12 a progressively decreasing gap is provided in the direction of rotation 15 of the rotor. Support of the extremities of the sliders on the stator causes their progressive opening or closing until they arrive tangentially at the closure strips. As shown, the sliders 11 are opened by slopes 17 and close under their own resilience on to the strips 1. <IMAGE>

Inventor: GEESEN MICHEL
IPC: G04F10/10

Abstract: The apparatus gives an indication of the location in time between two successive clock signals of an event to be timed. Such an event may be the arrival of a laser pulse at a satellite. An integrator circuit (C84) is charged by a relatively high charging current from a first current generator (66) during the period of time between the event and the next clock signal. The integrator circuit is then discharged by a smaller current of opposite sign from a second current generator (80). The ratio of the charge and discharge currents "stretches" the inter clock pulse time interval to a length that can be measured by counting clock pulses as the integrator discharges. For this factor to be useful, it is essential that the charging current remains constant during charging and from one charging occasion to the next. This is achieved by keeping the generator (66) generating current constantly and by diverting the current through an integrator circuit by-pass (R78) when not integrating. Switching is done using two transistors (Q71 and Q72) that are as identical as possible, and independently controlled in phase opposition. The by-pass current is detected and used to regulate the generator (66). Provided both transistors deviate in the same manner from nominal characteristics, this provides accurate compensation for variations in the other transistor also.

Abstract: A stencil printing machine having a curved printing table in which the printing table (1) is so arranged as to rotate about a rotating shaft (2) and has a to-and-fro motion imparted to it by a drive organ (3). A stencil (5) fastened in a frame (4) is so arranged as to follow the motion of the printing table (1), whereby it is displaced in relation to the scraper and ink charging devices (14, 15). These are in a stationary relationship to a frame forming part of the stencil printing machine. The material to be printed (6) is capable of being fed between the stencil (5) and the printing table (1). The printing table (1) has a printing surface which occupies rather less than 170° of the surface of a complete cylinder, and the radius of curvature of the cylindrical surface of the printing table is within the range of 400 - 500 mm, thereby providing both a suitable clearance angle (a) and a suitable delivery angle (b). Also provided are organs which ensure that the printing speed remains constant or essentially constant.

Abstract: In a method of compacting a layer of material a compacting machine with at least one drum is rolled over the layer, whereby the layer is acted on by gravitational force and an oscillating force. The latter is the result of applying a substantially pure rapidly alternating torque to the drum about its axis. The direction of action of the torque is reversed with a high frequency in relation to that with which the direction of travel of the compacting unit is reversed. The invention also embraces means for executing the method, wherein the torque on the drum is provided by at least two synchronously operating, rotating eccentric means (2a, 2b) spaces from the shaft (10) of the drum (1), and which are adapted such that the forces caused by their synchronous movement can substantially neutralize each other radially to the drum and coact to form a pure torque on the drum about its shaft (10).

Abstract: A modelling clay set based on grain flour clay comprising two types of clay:- a range of clays containing pigments, which change colour in response to pH variation, and a range of clays containing acidic or alkaline pH regulating agents. 
     Colour changes can be effected by kneading together amounts of at least any two clay species. Further colour changes are possible by mixing in an additional amount of:- either at least one of the clays containing a colouring agent. or at least one of the clays containing a pH regulating, or a mixture of both types of clay.

Abstract: A process for separately recovering zinc and lead values from zinc and lead containing sulphidic ore which also contains iron comprises subjecting ground ore to a first flotation step to float an initial lead concentrate containing zinc and produce zinc and iron containing tailings. The zinc and iron containing tailings are subjected to a second flotation step to float an initial zinc concentrate containing iron and also produce tailings. The initial zinc concentrate is subjected to a third flotation step to float a further zinc concentrate containing iron and also produce zinc and iron containing tailings. The zinc and iron containing tailings from the third flotation step and at least a lead and zinc containing portion of the initial lead concentrate are leached in a first leach step under oxidizing conditions at a temperature in the range of from about 130 to about 170°C in aqueous sulphuric acid soluton with a stoichiometric excess of sulphuric acid relative to the zinc content of from about 50 to about 150 % so as to give a terminal acidity of from about 50 to about 80g/L to produce a lead-containing residue and a first leach solution containing zinc and iron. The lead containing residue is separated from the first leach solution and the first leach solution is treated with the further zinc concentrate or calcine produced therefrom by roasting to dissolve zinc therefrom and precipitate a substantial amount of dissolved iron, thereby producing an iron containing residue and a second leach solution containing zinc. The iron containing residue is separated from the second leach solution, and the second leach solution is treated to recover zinc.
