Abstract: 1,128,776. Endless conveyers. ESKIMO PIE CORP. 24 Nov., 1965, No. 49982/65. Heading B8A. [Also in Division A2] In a method and apparatus for completely coating confections, particularly frozen bars of ice-cream, with a molten enrobing substance such as chocolate, the confections 20 are fed in succession, by a shoot or travelling belt 26 and through fixed guides, between the two opposed, spiked, vertical flights of a conveyer 27 comprising two endless, flexible, travelling belts 38 and 39 each carrying a plurality of thin, sharp-pointed spikes 40, on which the confections are impaled. The belts 38 and 39 are respectively supported by pulleys 46, 45, 44, 43, 42 and 51, 50, 49, 48, 47; the pulleys 46, 51 and 42, 47 being slightly smaller, in diameter, than the intervening pulleys, which are uniform diameter, so that the portions of the opposed flights supported by the intervening pulleys are substantially parallel, and the opposed flights diverge where they receive the uncoated confections, and where they discharge the coated confections 35, through fixed guides 37 (which remove coated confections from the spikes) on to a travelling, discharging belt 36. Each impaled confection 20 is thus conveyed through sprays or curtains of the molten enrobing substance issuing, in at least two different directions, from a spraying device 28, and then through blasts of air issuing from nozzles 30 and 31, which blasts remove excess enrobing substance from each confection, e.g. into a tank beneath the conveyer 27, and smooth the coating substance around each confection into a layer of uniform thickness. The coated confections may then be conveyed under a dispenser 33, from which crumbs of baked pastry or confectionary, candy or edible nuts are dispensed on to the upper surface of each coated confection before the coating thereon has hardened or set. Parts of the guides 37 may be heated, or heated smoothing irons may be attached to the inner sides of the guides 37, or positioned immediately thereafter, to obliterate punctured holes left in the coating.

Title: Method of and apparatus for monitoring a relationship between pulses
IPC: G01S7/527
Filed: 1974-11-21
Abstract: 1479212 Gauging dimensions WESTERN ELECTRIC CO Inc 21 Nov 1974 [26 Nov 1973]  50593/74 Heading G1G A dimension between two surfaces of an article is determined by an acoustic pulse-echo method in which the interval between echoes from the two surfaces is measured and the validity of the first pulse is tested by determining whether, after an interval commencing with the start of the first pulse, its amplitude remains below a predetermined varying value. In the Fig. 1 embodiment for measuring the thickness and eccentricity of a cable jacket 13 the cable passes from extruder apparatus through a cooling bath 16 where pulse-echo probes 21 sequentially check the thickness at four circumferential points. The probe signals are produced and processed by four channels 22. In each channel, echoes from the inner and outer surfaces of jackets 13 are checked for validity in logic unit 29 and the interval between them is obtained by a clockpulse counter 32. Valid counts are passed to a buffer store and converted to analogue form for driving a meter 37 and light. Thickness measures from the "left" and "right" channels 22 are compared to obtain at 40 an indication of jacket eccentricity. A similar indication of "top" and "bottom" eccentricity is obtained at 39. The echo validation in logic unit 29 assumes that valid echoes from the outer and inner surfaces of jacket 13 are generally as shown at a in Fig. 3, i.e. the first echo is of shorter duration and lower amplitude than the second echo. The unit 29, detailed in Figs. 2A, 2B (not shown) includes timegate and amplitude-threshold circuits, the latter having a threshold value which varies with time as indicated by the "dynamic threshold" lines at a in Fig. 3. For a two-echo sequence to be validated it must satisfy the conditions that (a) the first-echo amplitude initially exceeds the dynamic threshold, during hold-off pulse c, then remains below that threshold, during validation pulse d, (b) the secondecho duration is greater than a pre-set value, the width of second hold-off pulse e, and (c) the second-echo amplitude after a pre-set time, i.e. during second validation pulse f, is still above a fixed threshold value.

Title: Simplified diffractive colour filtering technique
IPC: G02B5/18
Filed: 1976-05-27
Abstract: The subtractive colour-diffracting filter has a phase structure which contains three different optical amplitudes. In this case, the first and the second optical amplitudes, which upon illumination with white light supply light of zero diffraction order with the colours of cyan and yellow, are selected such that their superimposition produces a third optical amplitude which diffracts green light into the zero order. It is possible thereby to combine a first phase grating fixed by variable optical amplitudes and serving for representing cyan, yellow and green, with a second phase grating which corresponds to magenta of fixed optical amplitude, in order to obtain a complete colour spectrum. <IMAGE>
