Title: Poultry food trough filling machine - has hopper travelling on guide with down pipes discharging into troughs
Inventor: BOERSMA FRITS
IPC: A01K39/01
Filed: 1978-07-19
Abstract: The machine automatically fills troughs in a poultry house with food in grain or meal form. It comprises a frame (1) travelling along a guide above the troughs (13), and equipped with a food hopper (2) connected to down pipes (12), these latter discharging into or above the troughs. The pipes can be connected by a rotary shutter (9), typically in the form of a roller or auger in a housing. The auger receives the fodder via a central top opening in its housing (11) and transports it sideways to outlets, to which the down pipes are connected. It can have sections with right- and left-handed spirals.

Filed: 1978-07-26
Abstract: The adjustment circuit connects an RC oscillator to the LF signal input to produce an output level of constant amplitude to adjust the noise suppression system. The RC oscillator consists of a Wien bridge connected to a circuit that stabilises its output level. The stabilising circuit has a variable resistor which forms part of the Wien bridge and therefore also serves to produce of constant level at the output of the bridge. The bridge contains the variable resistor shunted by a capacitor in one branch and the series combination of a capacitor and a resistor in the other branch.

Title: Colour picture tube with slotted mask - uses phosphor vertical strips which have constrictions lying in electron shadow of slotted mask transversal links
Inventor: ROTH ARNOLD ING GRAD
IPC: H01J9/227
Filed: 1978-07-28
Abstract: The mask slots for the electron passage are arranged in vertical rows and separated by transversal links, and corresponding phosphor elements are in the form of vertical strips on the inner surface of the front plate. Owing to their production by a photoprinting process, they have periodically occurring constrictions at least at the screen corner areas. Vertical distances between the constrictions are determined by the transversal links of the slot mask. Relative position of the constrictions (4) w.r.t. the transversal links (7) in the slot mask (6) is such, that they lie in the tube normal operation in the electron shadows of the links (7).

Title: Filter bag support basket - with short sections assembled by circlip inward bent longitudinal rod ends
Inventor: BAUR JAN VOM
IPC: B01D29/15
Filed: 1978-11-04
Abstract: A support basket for filter bags is assembled from several short sections. The longitudinal rods of each section are bent inward at the ends where they extend beyond the last spacer ring. A circlip is inserted to hold the two intermeshing ends together. The longitudinal rods of a first basket section are bent inward at the ends beyond the last distance ring. The second basket section has a similar bend on the longitudinal rods of the last spacer ring. After the ends of both sections have been intermeshed, a circlip is inserted to join the sections together. This simplifies the manufacture, transport and installation of very long filter bag support baskets. Dismantling is also faciliated.

Title: Resistance seam welding machine - where tungsten or molybdenum contact rings from working surface of copper electrode rollers
Inventor: HABENICHT GERD PROF DR
IPC: B23K11/06
Filed: 1980-01-18
Abstract: The workpiece travels through a welding gap formed by at least one pressure electrode roller made of material with good electrical and thermal conductivity, e.g. Cu. The roller is not in direct contact with the workpiece, but is provided with a rigid contact ring made of inert material and carrying the electric current to the workpiece. The ring is pref. supported by rollers, and may be eccentric or concentric w.r.t. the pressure roller. One pref. machine uses two electrode rollers, each fitted with a contact ring made of W, Mo, or their alloys. The actual working surfaces of the electrode rollers is formed by a hard, refractory metal or alloy based on W or Mo, so long working life is obtd., esp. when welding steel sheets coated e.g. with Sn, Zn or Pb, which rapidly contaminate Cu.

Title: Induction heat treatment of railway rail head - produces fine sorbite in mushroom while simultaneously tempering web and foot of rail
Inventor: KOERFER EGON DR ING
IPC: C21D9/04
Filed: 1980-02-22
Abstract: On leaving a hot rolling mill, a railway rail is cooled(I) until the transformation of austenite into the alpha phase is complete. Cooling(I) is then stopped, and the rail-head or -mushroom is then reheated(II) to form austenite, followed by rapid cooling(III) to form a sorbitic structure. Heating stage(II) is pref. employed simultaneously to temper the web and foot of the rail. After stage(I), the semi-hot rail is pref. fed into the induction heating appts. via guides which hold the rail until stage(III) is completed so the rails are free from distortion. A cold straightening operation may subsequently be used on the rails. The optimum wear-resisting metallurgical structure is obtd. in the mushroom without using costly alloying elements in the rail steel, while using the min. amt. of heating energy to produce the desired structure.

Title: Overload protection circuit for relay switching - combines inductive load with capacitance and semiconductor elements to reduce arcing at contacts
Inventor: ARAKI KAZUO
IPC: H02H9/04
Filed: 1980-03-07
Abstract: The overload protection circuit partic. for relay switching prevents arcing at the contacts (SL). In series with the switch is an inductive load (L) such as a relay coil. This is in parallel with a capacitor (C) and a semiconductor element (T2) which is in series with a rectifier diode (D). The semiconductor element suppresses the voltage peaks and the diode limits the forward current flow. Alternatively, a transistor (Tr) is inserted in series with the parallel capacitance, inductance, diode and semiconductor. As an alternative to the first circuit two semiconductor elements or a double element can be in parallel withg the capacitance and inductance. This absorbs the counter emfof the inductive load.

Title: Loose plastics waste scrubbing process - involves scrubbing liq. flow velocity, with gravity direction component, producing drag in excess of material buoyancy
Inventor: BUZGA HEINRICH ING GRAD
IPC: B03B11/00
Filed: 1980-07-29
Abstract: The process is intended for loose plastics waste with specific weight lower than scrubbing liquid. The mixture of waste and liquid is subjected to turbulence followed by the separation of the plastics and impurities. The scrubbing liquid is moved at a velocity having a component in the direction of the gravity force of such magnitude that the drag exceeds the buoyancy of the material. After scrubbing the flow velocity of the scrubbing liquid is reduced to such a value that the buoyancy of the material exceeds the drag forces on the material.
