Title: Improvements in methods of and apparatus for measuring the ovality of an object
Inventor: FOSTER DAVID BLYTHE
IPC: B07C5/12
Filed: 1964-08-24
Abstract: 1,121,122. Testing dimensions. NORTH ATLANTIC RESEARCH PRODUCTS Ltd. 20 Aug., 1965 [24 Aug., 1964], No. 34599/64. Addition to 1,048,585. Heading G4H. [Also in Division G1] Two separate systems as claimed in Specification 1,048,585 are arranged to inspect an object at different angles. The object may be a bottle B, Fig. 1, lamps L1, L2 separated by 70 degrees causing the bottle to cast shadows S1, S2 upon arrays of photo-cells 7-16. Photocell 9 is adapted to trigger the circuit 1 when the shadow S2 is in the registered position and photo-cell 12 triggers circuit 2 in the same way. The limits of shadow S2 are monitored by photo-cells 7 and 8, the output from the latter being inverted at 23. Height detecting photocells 13, 14 are placed at the upper edge of the shadow, the output from the latter being inverted. If the bottle has the correct dimensions, cells 7 and 13 are in light and 8 and 14 are dark at the instant the circuit 1 is enabled by photo-cell 9. Gate 25 responds to the presence of four signals and the circuit 1 is set. An extra photo-cell 15 prevents erroneous operation after the bottle has passed the inspection position. AND gate 24 responds to the presence of signals from cells 9 and 15. The arrangement for the array for shadow S1 is similar. Relays 3 and 4 connected to circuits 1 and 2 have contacts adapted to light lamps to indicate that the bottle passes the dimension test or is to be rejected. The slope of the mouth of the bottle may be tested by placing a spring-loaded skid so that it slides on the mouth, a mirror on the skid being adapted to reflect light on to a photocell only if the mouth is level. The bottle may be centralized on a conveyer by mechanically linked fingers between which the bottle passes. A signal indicating that the bottle is in the exact position of register may be obtained by two photo-cells which receive light passing on either side of the bottle. The signal from one oell falls as the other rises and a comparator Y responds when they are baanced to produce a " read now " signal.

Abstract: 931,637. Preparing dough. F. J. SUNTHEIMER. Sept. 28, 1961, No. 34943/61. Class 49. A dough for yeast-raised products comprising a mixture of dough-forming ingredients, including flour and yeast, is made by mixing the ingredients in the presence of air under pressure at a temperature of from 66‹ to 72‹ F. In the production of a regular dough by the sponge and dough process, there is introduced into a tank 10 through a temperature-controlled pipe 11 about 32 1b. water at a temperature of 72 ‹ C. and then 2¢ to 5¢ lb. yeast and 3 oz. salt are added. These ingredients are mixed while at a temperature in the range 66‹ to 72‹ F. in the presence of air delivered by a pump 14 at a gauge pressure of between 20 and 35 1b. per square inch until after 5 to 10 minutes a pH of 6-6.5 is attained, when the mixture is transferred to a dough mixer 22; to this 60 1b. flour, a small quantity of dough improver (specified) and 5 1b. of shortening are added with agitation. From a further 32 1b. water in a tank 25, a quantity of 24 1b. is discharged at a temperature of between 66‹ and 72‹ F. into the dough mixer 22 and then the following doughing components are added: 40 1b. flour, 2 1b. salt, 4 1b. sugar, 6 1b. milk, ¢ 1b. malt, and, optionally, a small amount of ethyl alcohol. The remaining 8 1b. of water in tank 25 is carbonated to the extent of 57-115 cc. carbon dioxide from a supply 30a at a pressure of 30 1b. per square inch and the carbonated water also is delivered to the dough mixer. An agitator 35 is operated at high speed for about 10 minutes to mix the combined ingredients until a predetermined temperature in the range of from 75‹ to 84‹ F. is attained, the dough produced is removed, panproofed for 30 to 60 minutes and prepared for baking. In one of several alternative procedures described in detail, powdered milk, salt, sugar, malt and ethyl alcohol of the doughing components may be added in the tank 25 while maintained at a gauge pressure of between 20 and 35 1b. per square inch by a pump 41. A slightly modified procedure is employed when utilizing the straight dough process. Eggs are included in certain of the formulations disclosed.

Title: Improvements in or relating to travelling wave tubes
IPC: H01J23/28
Filed: 1953-12-16
Abstract: 734,479. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. Dec. 16, 1953 [Dec. 23, 1952], No. 35017/53. Class 39 (1). A travelling-wave tube has a delay line comprising a hollow wave-guide from opposite walls of which U-shaped wire elements 31, Fig. 1, extend in a linear array so as to overlap in an interdigitated pattern, and means for projecting a beam of electrons through the overlapping portions of adjacent wire elements. The device may be a backward wave oscillator, as shown, or an amplifier using forward or backward wave modes, Fig. 3 (not shown). For a backward wave device the spatial harmonic selected for interaction with the beam is a forward component of the wave which has a backward energy flow, and in the backward wave oscillator the wave is initially set up by noise currents in the beam. The forward wave amplifier also uses a spatial harmonic mode. The rectangular sectioned guide 18 is terminated non-reflectively at the collector end by a wedge 22 of dielectric coated with lossy material, e.g. powdered graphite, and at the gun end is connected to output guide 36 via a tapered im, pedance-matching section, right-angle bend 25, guide 24 and guide 26; guides 26, 36 have capacitative coupling flanges, and all the guides are of rectangular section. The cylindrical beam is focused by solenoid 35. Brillouin-type flow may be used, as described in Specification 697,550. The impedance matching at the output end is assisted by tapering the lengths of U-shaped elements 31. The elements 31 have a length, i.e. the height of the U, less than n #G/4 where n is any odd number, i.e. avoiding multiples of #G/4 where the elements are resonant. The electron transit time between adjacent elements is about a half period of the wave. In making the delay line, gold-plated molybdenum wire is wound as a helix on a steel mandrel of rectangular cross -section and the wound mandrel placed in a groove in a copper block, after which the wire is brazed to the edges of the groove. The brazing operation is facilitated by gold plating the edges of the groove. A taper may be ground at either or both ends of the wound helix for impedance matching. The steel mandrel is then dissolved chemically. Two such block and element assemblies are brazed to two copper'side plates to form the complete delay line. The tubes may operate at millimetre wavelengths.
