Title: Angular layout of conveyor belt guide - has horizontal slot which bisects angle formed by conveyor belt and gives 90 deg. change of direction
Inventor: WAGNER JOSEF
IPC: B65G15/60
Filed: 1973-06-28
Abstract: Two support plates are fixed side by side so that a slot is formed between them. A number of rollers, overlapping the edges of the slot are carried by forked spigots on the upper side of the plates. The approaching conveyor belt is taken through the slot around a guide roller below and then back up again through the same slot. On leaving the slot, the belt forms an angle on a horizontal plane with the belt entering the slot. The set of rollers at each top edge of the slot run parallel with the movement of the belt section for which they provide low friction support. The spacing between the rollers is determined by the load which the conveyor carries. To correct lateral belt movement, the rotational plane of the support rollers can be adjusted.

Title: Use of finely ground bran as low-calorie foodstuff extender - to replace flour and other carbohydrates without spoiling taste of food
IPC: A23L33/21
Filed: 1973-09-11
Abstract: Finely ground bran (particle size =50 mu, pref. =20 mu) is used as an extender in low-calorie foodstuffs. An anti-oxidant can be added (pref. 0.01-1 wt. %) such as octyl gallate, dodecyl gallate, butyl-hydroxy-anisole or butyl-hydroxy-toluene, to prevent taste deterioration. Bran has low calorie value, but contains a considerable amt. of vitamin B1 and after vitamins. Bran satisfies appetite. Bran does not give the sandy taste characterizing microcrystalline cellulose powder used for this purpose heretofore. Bran improves digestion. These properties are due to the combination of pentosan, lignin and cellulose contained in bran.

Title: Brake lining wear indicator - has indentations on shoe edge giving warning noise by striking screw on drum when lining worn to limit
Inventor: BEYRER KARL RICHARD
IPC: F16D66/02
Filed: 1974-02-09
Abstract: On drum brakes with automatic wear adjustment it is possible that through neglect a critical extent of lining wear is not discovered in time. The present arrangement offers a simple solution applicable even on drum brake system already in operation by profiding on the edge of brake shoe (30) a number of indentations (34) directed towards the drum perimeter. An adjustable screw (36) with a lock nut (37) fitted at one point of the b rake drum periphery near the drum shield clears the tip of the screw as long as the brake lining is new. As the automatic wear adjustment pushes the brake shoe further outwards to the drum periphery, at one point it comes near enough to touch the screw tip and an audible noise occurs giving warning to the driver that the lining is worn to the limit.

Abstract: The control system has an electronic impulse generator and a decoding stage with an interchangeable programme matrix which contains the tone sequence of the melody in the form of electronic elements and controls the electromagnets. The decoder stage pref. comprises a ring counter and decade counters. The impulse generator frequency needs only to be variable in one or two stages and any desired tone frequencies can be realised. Very lengthy and complex punched musical scores can be processed. Extension is simply realised by providing further decade counters. The matrixes are most conveniently formed as printed circuits which are easily stored and changed.

Title: Fuel injector pump - with delivery rate dependent on plunger position with respect to elliptical fuel return opening
Inventor: YAMADA TADASHI
IPC: F02M59/26
Filed: 1974-05-08
Abstract: The pump housing (1) contains a boring (2) in which a plunger (3) is able to reciprocate and at the same time turn. A fuel delivery chamber (15) with a delivery pipe union at its upper end and a spring loaded non return valve at its lower end is screwed into the housing above the plunger boring and amplifies fuel impulses. The cylinder boring (2) has inlet and overspill openings (8, 9) in communication with the pump fuel reservoir. The plunger has an axial boring (11) extending from its crown (10) and opening out at an annular regulator groove (12) formed in its outer surface and at right angles to the plunger axis (0). The external annular regulator groove is in communication with the overspill channel (9) when the plunger starts its delivery to produce a gradual pressure. Since the overspill channel opening is elliptical, four sections are available to regulate the return flow when the plunger is turned.
Patent DE-2422711-A1 (DE)
Title: Removal of radioactive iodine from aq. solns. - by two-step pptn. jointly with other radioactive isotopes
IPC: G21F9/00
Filed: 1974-05-10
Abstract: Removal of radioactive iodine from aq. solns. by a 1st pptn. step with AgNO3 in an acid medium (pH 4.0, pref. 2.5-3.0), followed by a 2nd pptn, step in alkalin medium (NaOH) together with ions of radioactive Cs, Sr, Ba and Co isotopes and other heavy metals with addition of water soluble substances capable of precipitating the radioactive cations, is improved in that the 2nd pptn. step is effected by adding NaO4 to adjust pH to 7.0-9.0, pref. 8.5-9.0 (without any filtration between pptn, steps. AgI does not dissolve in media having a pH below 9.0, so that there is no need to filter off the AgI pptd. in the 1st step before the 2nd (alkaline) pptn. and, hence, one filtration only is carried out (after the 2nd pptn. step). Thus, the technology of the process is considerably simplified. Radioactive iodine and other radioactive substances are removed to acceptable extent.

Title: Electronic casing jointing for high frequency shielding - uses bolts which deform one casing to provide excellent contact between casings
Inventor: JORDAN BODO
IPC: H05K9/00
Filed: 1974-09-20
Abstract: The two casings are overlapped and clamped together by means of bolts (3) and specially shaped nuts (4). Each nut has a cone shaped (5) inner face which when tightened up, deflects the inner casing (2) into a cavity (7) in the outer casing, so that electrical contact is established along a line of such bolts and good shielding is achieved. Instead of a conical face on the nut, a more complex concave conical shape may be used, and this fractures the oxidized layer on casings of aluminium when deflection occurs. Other variations may be used with thicker casings, using external clamping elements, and may be used with casings with inner insulating layers.
