Title: Process and apparatus for manufacturing and applying a covering of chocolate mass to filled hollow chocolate bodies
IPC: A23G3/20
Filed: 1930-04-03
Abstract: 347,449. Moulding confectionery. WINKLER, A., 30, Seminarstrasse, and DUNNEBIER, M., 46, Engerser Landstrasse, both in Neuwied, Germany. April 3, 1930, No. 10630. [Class 87 (ii).] The chocolate coverings, to complete the closure of hollow shells of chocolate filled with liquid or other material, are applied by delivering a layer of heated chocolate to a smooth endless band maintained at a regulatable temperature, and causing the knife-edged upper parts of the moulds containing the filled shells to contact with the band and stamp out the lids or coverings from the plastic layer. Fig. 1 shows one construction in which hot chocolate escaping at the thin screwadjusted slit 29 from the jacketed container 26 sticks to the surface of the polished steel band 16 and is pressed against the filled shells on the belt 13 immediately underneath the bowed spring 25. The stamped portions are sufficiently fluid to adhere to the warm upper edges of the shells to form an integral covering therefor. The stamping of the lids is accompanied by cooling and hardening of the layer in contact with the band due to conduction from the cooling chamber 24, which allows the lids to separate readily from the band. A spring scraper 32 removes surplus adherent chocolate from the band, while an adjustable weight 23 applies tension to the non-driving roller 15. Fig. 3 shows a modified form in which the hopper 26 delivers to the upper side of the steel band 16 supported on an internally-heated roller 15 and an internally-cooled roller 14. The upper edges of the filled moulds are heated by contact with the steel band 41 running near to heating devices 42. The stamping occurs on the lower run of the band 16 as in the previous case.

In the construction shown in Fig. 1, the socket a is fitted with two rings f of resilient material, such as india-rubber, abutting against a central rib e, and near the ends with two rings g of rope &c. which may be fixed in the grooves by cement. On account of the resilience of the rings f, a slight sagging of the pipes may occur without impairing the efficiency of the joint. In a modification, Fig. 4, the two rings f are replaced by a single ring f<1> located in a groove in the socket a, the central rib e being dispensed with. A temporary partition j may be fitted in the falling-hole i so as to ensure that the material shall flow into the socket in one direction only.

Abstract: 646,781. Screw conveyers. CHRYSLER CORPORATION. April 23, 1947, No. 10841. Convention date, May 10, 1946. [Class 78 (i)] [Also in Groups V and XXXVII] Plastic material is fed to the nozzle 15 of an injectionmoulding machine by a screw 21 which is driven by an electric motor through worm gearing and which is engaged by gears 30, 31 serving as rotatable dams to prevent the material operated on by the screw from turning therewith. The nozzle is telescopically mounted in the end of the injection apparatus and is caused to engage the mould. After the mould has been filled the pressure built up in the injection apparatus causes the latter to rise from the mould, the nozzle meanwhile remaining in contact therewith. This movement of the injection apparatus relatively to the mould is utilized, by the aid of electric circuits, first to reverse the movement of the screw 21 for a brief period, and then to stop the screw. Specification 605,867 is referred to.

Abstract: 1529043 Detecting direction of current flow STANDARD TELEPHONES & CABLES Ltd 17 March 1977 11336/77 Heading G1U A flow of current from terminal 2 to terminal 1 forward biases diode 6 reflecting the low resistance 3 into the secondary of 1:1 transformer 9, such that this provides high attenuation of the signal B from generator 13 passing through voltage divider 14, 15. Threshold device 19 therefore supplies a first level signal to comparator 22. Since diode 8 is reverse biased for this polarity, no attenuation takes place for signal A and threshold 21 provides a second level to comparator 22 which recognizes the relationship of the two signals and indicates the appropriate polarity. For an opposite direction of flow, the comparator inputs are reversed.
