Patent DE-2408964-A1 (DE)
Title: Hand- or motor-driven grass-mower - has one or more wheels positioned behind the blades and with concentric axle
Inventor: HASELOFF FRITZ
IPC: A01D34/82
Filed: 1974-02-25
Abstract: The wheel system and cutter-blade system can be varied so that, for instance, one wheel is situated behind the blades, and two wheels are on the same central axle as the blades. This achieves a comparatively wide cutting area. Alternatively, one wheel can be behind the blades, which are arranged so that there is a jaw-type aperture between, so that trees or stalks which get in the way can be cut round. In this case, the two outer blades are mounted on the same central axle as the wheels. This enables the mower to cut well over the edges of lawns.

Title: Springs for connecting links on counterblow hammers - multiple rubber and metal disc element with increased working life
Inventor: POBINGER PETER DIPL ING DR
IPC: B21J7/34
Filed: 1974-03-16
Abstract: A composite rubber and metal spring element for use on both ends of the link connecting the upper and lower rams of counterblow hammers. Both ends of the link terminate in a rod which passes through a hole in a lug on either the upper or lower ram. The end of the rod is fitted with a plate and the spring-element is fitted between this plate and the contact-face of the lug. The element consists of a row of elastic rubber discs interspaced with metal plates having a double-sided flange at the periphery. Both ends of the element terminate in a rubber disc so there is no metal-to-metal contact either on the faces of the lugs or the endplates on the rods. The element has twice the life of the usual spring-element due to its superior resistance to stresses, vibration and heat arising in operation.

Title: Felt ring blank mfg. - has separate forming and compression stages with sliding transfer to double mfg. times
Inventor: KOTLYAR YAKOV IOSIFOVICH
IPC: D04H17/00
Filed: 1974-10-04
Abstract: Felt ring blanks, composed of wool or wool mixed with other fibres for use in machinery construction or in transport or in the automotive industry, are mfd. using a connection between the outlet of a cyclone mixer and the forming cylinder, with a perforated base on which the fibres are laid and air drawn out by suction. Each forming cylinder and base has a common sliding movement to an axis parallel to the axis of the forming cylinder to transfer the material to a compression unit. The compression chamber is coupled with each forming cylinder, and is fitted with internal heated plates which give an oscillating movement in opposing directions to compress the fibre material between them to give the ring blank. The forming and compression phases are operated and powered separately. The apparatus develops felt ring blanks of 400 mm diameter, 40-45 mm high, with a density of 0.45-0.50 g/cm3, giving an operating time twice as fast as conventional machines.
Patent DE-2449109-A1 (DE)
Title: Orientation of cylindrical components - with short reduced diameter end are axially aligned in vibrator feed chute and oriented in output stage
Inventor: WEBER JOSEPH
IPC: B65G47/14
Filed: 1974-10-15
Abstract: Small cylindrical components with a small diameter end section are fed through a feed section into a profiled channel, where they are aligned with their axes parallel. At this stage the channel is filled with components located in one of two possible positions displaced by 180 deg. In order to arrange all components to be positioned such that they are oriented in the same way, an output stage with profiled guide-ways is used. The output stage is cylindrical and the guide-ways which are cut into the internal wall are displaced 180 deg. at the top edge. The guide-ways are sufficiently deep for the small diameter end section. Each guide-way moves through 90 deg. in a partial axial helix until joining a common slot. Components initially displaced by 180 deg. are thus rotated as they move axially, until achieving a common orientation.

Title: Automatic warp beam mounting - uses limit switches and control circuits to position and clamp the beam in place
Inventor: THEIHSEN HANS
IPC: D02H13/28
Filed: 1974-10-25
Abstract: In an appts. for the assembly of a winding beam on a winding machine, such as for warp yarns or similar materials, with a motor-driven laying out of the beam when raised, a sensor unit works together with an electric control unit to insert and remove the beam into or from the bearing supports through successive and automatic control signals for the operation of the laying out unit and/or the adjustment drive of the support shafts. The system eliminates the number of manual operations required in placing the warp beam in position, and removing it when it is fully wound.
