Title: Monitor for crusher and hopper level control - has logic circuit receiving signals from sensors high and low in hopper
Inventor: JEMELKA JAROMIR
IPC: B02C25/00
Filed: 1973-11-14
Abstract: Monitor for bulk hopper and crusher space of a jaw crusher has the electrical signals of at least two sensors in the hopper fed into a logic element. When the crusher space is full, the higher and lower sensors emit a zero signal, and with partially filled crusher space the higher sensor gives a unit signal and the lower a zero signal; with a curvature or a built up in the hopper, the higher sensor emits a zero signal and the lower a unit signal. The signal of one or other sensor can be substituted by the power input of the crusher drive motor. The simple circuit gives a novel control system.

Title: Filtration pipe for clearing sewage and contaminated water - built-up from plastic strips located by end plates
Inventor: RUHL KARL
IPC: B01D21/00
Filed: 1973-12-06
Abstract: A device for clearing sewage and contaminated water, etc has at least one filter tube, the mantle of which is built up from radially located, axially extending thin blades or slips, retained in the circular grooves of cover or end plates and forming the filtration surface. The contaminated water is fed up or down through one of the plates holding the gp. of slips whilst the exhaust connection for the slude is in the other slip retaining plate. The plate at the opposite end to the waste water inlet acts as a barrier against which the sludge banks up. The slips consist of thin narrow strips of plastic matl. thickened at top and bottom, for pref on both sides with a layer. This ensures the min. gap over the full length of the filtration surface, widening gently towards the outer point. A simple and cheap method of continuously filtering sewage without the filtration surface or the inner dia of the tube formed by the wall of filler blades being choked by sludge.

A self parking control switch is coupled to the motor which is connected to the relay in such a way that the motor current is maintained until the sipers assume the parked position. The intermittent relay control is combined with the continuous sweep control in such a way that no extra connections are required between the system and the dashboard with one of the settings of the parking switch providing the current connection to the motor.
Patent DE-2444804-A1 (DE)
Title: Guard for piezo-electric cigarette-lighter - consists of easily inserted and removable cover for base-bottom
Inventor: POTAK SANDOR ING GRAD
IPC: F23Q2/28
Filed: 1974-09-19
Abstract: The base part contains the filling-valve for the fuel and the adjustment-device for the flame-level. Direct accessibility of these two devices must be avoided therefore, the bottom surface of the base part is covered with a component that is easily inserted and removed. As a result, the filling-valve and the flame adjustment are accessible only after the removal of the covering component, which leads to an increase in the operational dependability of the lighter and excludes the possibility of unintentional adjustment and operational movements. The covering component may have spring claws.

Title: Counting sensor for moving stacked sheets - with switch actuator positively displaced by steps between staggered sheets
Inventor: SCHICK GUENTHER DR ING
IPC: G06M7/00
Filed: 1974-09-27
Abstract: The sensor comprises a pivoting lever arm (1) attached to rotating discs (3) which roll on the surface of the counted material and are held down by their own weight. A projecting member (6) extends beyond the circumference of the discs adjacent to or between the latter. The member is supported by a spring in such a way that it can be moved to a position within the circumference of the discs. In the rest position the spring is in contact with a stop which may also serve as a limit switch. The tip of the pick-up projection may have a sharp edge or be rounded to a very small radius of curvature.

Title: Slide chocolate box with two slides - has one slide with one sorting inlay with gripper plate on slide walls
Inventor: LUCAS RICHARD ERKELENZ
IPC: B65D5/38
Filed: 1974-10-02
Abstract: The slide box is especially for chocolates and consists of a surrounding carton with two box-shaped slides with sortings inlays where each slide has a length corresponding to half the length of the carton and has a grip plate at the side wall which closes the side opening of the carton when the slide is pushed in. There are also devices to lock the slide with the carton and to prevent a complete withdrawal of the slide. Specifically there is a box-shaped slide (20) of the length of the carton (10) with at least one setting inlay (25) with its gripper plate (22, 23) on the side walls (21, 31). On the long side walls are devices (44, 45, 46, 47) for releasable locking the slide (22a) in one of its two half withdrawn portions and for preventing complete withdrawal. These devices act with limiting stops (40, 41, 42, 43) formed close to the side openings (11, 12).

Title: Thermal degasification of turbine main condensate and feed water - filtration forms unit with rigid water injection system
Inventor: BRUENING ROLF ING GRAD
IPC: B01D19/00
Filed: 1974-11-16
Abstract: Turbine condensate and feed water are degasified thermally in a horizontal or vertical feed water vessel, into which the water to be degasified is introduced via an injection system, and in which the necessary heat is transferred from a steam feeding and distributing system. The water feed pipe extends vertically downwards through the upper mantle of the vessel into the centre of a screen opening downwards and limiting the spread of the sprays of feed water, the upper zone of the screen having connections through the vessel cover for venting air. The bottom end of the feed pipe has a cowl with radial bores spaced around the circumference and at such a height that as the load is applied, the jets from the cowl reach the screen. At its top end, the feed pipe has a filter arrangement to which the connection for the water is fixed. Simple design giving very high degree of security of operation. Dirst can be blown out during operation.

Title: Fast clamping arrgmt for presses - has remotely positioned operating member for clamping levers with shaped head
Inventor: RASENBERGER OTTO
IPC: B30B15/02
Filed: 1974-12-07
Abstract: The clamping levers can be pushed by the transmission members into slots in the plate to be clamped after which they are pulled down. Each clamping lever is connected to a tie rod at a coupling point. Guide rollers are provided at the press tool side of the coupling points, which are pressed against a guide face. The tie rods are connected at the other ends in a crank point, to drive levers which are supported from fixed pivot points. A lever is mounted between the tie point and the crank point in such a way, that when the drive lever is operated, a curved path is described by the tie point. When the tie rod is practically stationary, the curve extends over a vertically section. During an oscillating movement of the tie rod, the curve moves over a section which is practically normal at the first section.

Title: Pipe locking system for muff couplings - has two connecting bolts between pipe clamps which are pulled together
Inventor: HUCKENBECK WILHELM
IPC: F16L21/08
Filed: 1974-12-14
Abstract: The two part clamping rings are connected together by an adjustable tie bolt. One clamping ring (1) fits on the inside pipe (3) and the connection points are used as support journals (5) for connecting bolts (6). These run parallel to the pipe and have conical ends (7) which locate in the journals. The other ends of the bolts are threaded and fit through support eyes (9) in the two part clamp on the other pipe. As the nuts (10) are tightened on the bolts, the conical ends pull the first clamp on the inserted pipe (3) towards the second pipe.
