Patent DE-2420620-A1 (DE)
Title: Glazing or other building joint sealing strips - of bevel-cornered resilient silicone rubber pieces cold-vulcanised together
Inventor: HAGEN PETER
IPC: E04B1/684
Filed: 1974-04-27
Abstract: The system is designed to promote simple but wholly effective sealing between building components, esp. as applied to metal window glazing. The sealing shaped section strips, for flexible insertion into the joint gaps, are made of resilient silicone rubber, out to a bevelled edge at the corners and other connecting points; these are inserted so that they abut on each other, and at these points they are joined together by means of cold-vulcanised silicon rubber, or other rubber. They may be the only sealing provided in the joint gaps, or they may be combined with other sealing material, also substantially composed of silicone rubber. The strips may be produced by a process of extrusion moulding and hot-vulcanising.

Title: Combustion engine with rotating vane pistons - has piston to produce compressed air and combustion products driving second piston
Inventor: MIELITZ GUSTAV BERNARD
IPC: F01C1/44
Filed: 1974-12-21
Abstract: A first circular piston rotates about a fixed axis inside a three lobed chamber. A vane is slidingly disposed in a slot in the piston and on rotation of the piston serves to induce air from an inlet and and deliver compressed air via a port to a second similar piston which rotates in a second chamber under the influence of the products of combustion generated by burning fuel in the compressed air received from the first piston. Gears drive the first piston from the second piston. The three lobed chambers are characterised by being a constant diameter as measured through the central axis and by having two diametrically opposed arcs of constant radius.

Title: Signal adjuster for a memory controlled manipulator - is used for carrying out repetitive operations and includes comparator and buffer units
Inventor: WATANABE TAKEHOKO
IPC: B25J9/18
Filed: 1974-12-30
Abstract: The adjuster comprises an arrangement for generating a digital position signal which represents the actual position of the manipulator; a memory unit for storing the digital position signals which are generated during the adjustment of the manipulator and a comparator to compare the output signals of the store with the output signals generated by the arrangement when the manipulator carries out an operation. The comparator also generates an error signal which is proportional to the difference between the two signals. The adjuster further consists of an arrangement for controlling and operating the manipulator in such a direction that the output error signal is reduced to zero.

Title: Automatic electric toaster with conveyor belt - has dust free unit containing noiseless electromagnetic stepped switch drive
Inventor: REMY HERMANN DIPL ING
IPC: A47J37/08
Filed: 1975-01-17
Abstract: The automatic electric toaster has a conveyor mechanism which moves the slices of bread past the heat element and for this purpose is in active engagement with an electromagnetic stepped switch drive, the exciter of which is fed by a pulse generator. Since the mechanical force required for moving the bread slices is slight the parts of the drive are relatively small and cause no noise. The conveyor mechanism can be driven by a conveyor pawl which is coupled to the armature of a stepped switch magnet and return spring connected to the pulse generator. The frequency of the pulse generator can be controlled to adjust the speed of the conveyor and thus the degree of browning of the toast.
Patent DE-2501701-A1 (DE)
Title: Wheel balancing appts. for motor vehicles - displays weight and position of required ballast without wheel removal
Inventor: KREHAN PETER DIPL ING
IPC: G01M1/28
Filed: 1975-01-17
Abstract: The vehicle is positioned with the relevant wheel resting on a drive which is driven by a motor tupically at about 900 r.p.m. A test apparatus consisting of a truncated conical drum and its attachments is then pressed against the inner wheel rim by a spring, so that it runs concentrically with the wheels. An accelerometer provides an output from this via a slip ring and a compensating weight or ballast attached to this apparatus is then positioned by an electronic control system so that the minimum unbalance is achieved. The bassast is positioned bothe radially and circumferentially so that the angle and equivalent required fixed ballast weight can be read from a scale at the end of the sequence.

Title: Bow rudder for tugboats - uses rotary inactive nozzle channel as auxiliary steering device
Inventor: LOOKS ARNOLD
IPC: B63H25/38
Filed: 1975-02-05
Abstract: The rudder consists of a horizontal piece of ducting (11) under the hull near the bows, centrally pivoted on a vertical spindle (14) with its foot supported in a frame (12) which also protects the ducting. The ducting cross section may be rectangular, circular or oval and it may be built up, or internally subdivided. It operates as an auxiliary for the main rudder. When the ducting is angled to the centreline, the deflected water flow exerts a force on the vessel tending to make it change direction. In conjuction with, or in opposition to, the main rudder force this substantially improved manoeuvrability.

Title: Brine reflux cleaning for meat pickling machine - in basin with vertical overflow pipe and bottom passage in partition
Inventor: HUEBNER MAX
IPC: A23B4/30
Filed: 1975-06-03
Abstract: The brine return from a pickled meat injection machine is cleaned of meat and bone residue and of foaming albuminous substances in a basin with a vertical overflow pipe which governs by its top edge the height of the fluid level. A partition which separates the part surrounding the overflow pipe from the rest of the basin extends above the fluid level and has a passage near the bottom. This retains the floating albuminous substances which are impossible to filter. Sieves which clog easily are not needed. The basin is easy to clean and does not require any re-assembly after cleaning.

Title: Groove cutting device for road surfaces - has drum cutting system with intermediate drum segments and drive shafts
Inventor: FAIRWEATHER ERNEST SIDNEY
IPC: E01C23/088
Filed: 1975-06-26
Abstract: A groove cutting device is esp. for operation on road surfaces. It has a rotating cutting drum with two end elements axially mounted on the central shaft. The cutting drum segments are constructed with aperture cutting elements mounted on further lower shafts.
