Abstract: 801,807. Sewing machines. VEB SPEZIALNAHMASCHINENWERK LIMBACH. Oct. 3, 1955, No. 28153/55. Class 112 A multi-needle embroidering machine comprisese two parallel rows of needle heads mounted on a common frame disposed 'freely above a common continuous table, and a common carrier for the embroidery frames movable on the table between said rows. Needle heads 1, 4 are respectively mounted on parallel structures 3, 5 which are disposed above a common table 2 and are interconnected at their respective ends by members 7. An electric motor 12 drives a horizontal shaft 13 which in turn drives the respective needles and loopers via vertical shafts 14, 15. Shaft 13 contains clutches 18, 19 which enable either row of embroidering tools to be disconnected from the motor and then to be controlled by respective handwheels 17, 16. The embroidery frames 26 are connected by holders 25 to the opposite sides of a common table-like carrier 6 which is supported on table 2 at points 35. An automatic Jacquard mechanism 21, mounted at one side of the machine, controls the longitudinal movement of carrier 6 by means of a rack 29 acting on a gear carried by a transversely slidable bearing 30, and the lateral movement of the carrier by means of racks 33 which are driven from a shaft 31 and act on gears carried by longitudinally slidable bearings 34. The table 2 and carrier 6 are preferably covered by plastics material, and the carrier 6 is provided on three sides with a vertical flange 38 for retaining the embroidered material which passes on to the carrier inwardly from both sets of embroidering tools. In a modification, the structures 3, 5 are supported centrally by a separate structure and the Jacquard mechanism is also disposed centrally opposite the latter.

Title: Electrical filters
Inventor: CROWCROFT PETER LESTER
IPC: H03B5/28
Filed: 1960-08-15
Abstract: 932,915. Automatic tuning control. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 24, 1961 [Aug. 15, 1960], No. 28256/60. Class 40 (5). Relates to an electrical filter arrangement designed to have a variable characteristic pass frequency, which follows variations in the frequency of an input signal or of a selected frequency component of a complex input signal, in which the variations of frequency are achieved by comparison of the frequency of the input signal or the selected component with a frequency which is equal to the characteristic pass frequency of the filter, to produce a frequency difference correction signal which is dependent in phase and amplitude on the direction and magnitude of the frequency difference, this correction signal being applied to the filter to change its characteristic pass frequency in the appropriate direction. A signal from which a frequency component is to be extracted is applied to the input of active filter 11 (Fig. 1), part of the output 12 being applied via a lead 13 to a mixer 14. To the mixer is also applied an output from a local oscillator 15 whose frequency is exactly that of the filter 11, and a signal is obtained from the mixer equal in frequency to the difference between the filter frequency and the signal, and whose phase lag or lead is indicative of the sense of the deviation. This signal is used to energize the two-phase servomotor 18 which alters the frequency of the oscillator 15 and the filter 11 so as to reduce the difference from the frequency of the incoming signal. In the detailed circuitry (Fig. 2) of either the filter 11 or the oscillator 15, each takes the form of a Wien bridge oscillator. The output from the pentode 19 is fed to the grid of triode 20 and thence back as negative feedback via the circuits R2C2 and R1C1 to the grid of pentode 19 and as positive feed-back via the fixed resistors R3, R4 to the cathode of the pentode. The adjustable negative feed-back path acts as a rejector circuit passing all frequencies other than that to which it is tuned, so that the circuit may function as the oscillator 15 only at that particular frequency, when the negative feedback is just less than the positive. When acting as the filter 11, the negative feed-back is slightly in excess of the positive.

Class 98(2) A colour photographic process comprises the development with a colour developer in the presence of a colour coupler of an exposed photographic material carrying a gelatino silver halide emulsion which has been formed by reacting, in the presence of gelatin and a rhodium salt an aqueous solution of a soluble silver salt with an aqueous solution of soluble halide. The rhodium salt increases the contrast obtained (usually with a reduction in speed), and about 0.001 molecular proportion of rhodium salt per 100 molecular proportions of soluble silver salt may be used. The colour coupler may be incorporated in the developing solution or may be incorporated in the emulsion layer or in resin particles which are dispersed in the emulsion layer. The material may be used in printing: In Example 1, an emulsion is prepared by mixing aqueous solutions containing (a) potassium chloride, potassium bromide, gelatin and rhodium trichloride and (b) silver nitrate, and subsequently treating in the normal manner.
