Patent DE-2401566-A1 (DE)
Title: Winch rope spooling mechanism - has sliding slotted ring and removable bar engaging with external ring claws
Inventor: BORNSCHEIN HANS
IPC: B66D1/36
Filed: 1974-01-14
Abstract: The rope is guided by means of an outlet slot in a spooling ring, working on the spiral rope grooves in the drum and sliding in the axial direction of the drum as it rotates, while a guide rod parallel to the drum axis prevents ring rotation. A number of claws are provided on the outside of the ring, working in conjunction with an easily removable guide rod, enabling the angular position of the rope slot to be varied. The claws can be integral with the ring and evenly spaced round its periphery. The ring can be split into two halves joined by coupling pieces screwed into place, claws being provided on the coupling pieces. A clamping ring can be provided inside the spooling ring, turning but not sliding in relation to it, and bearing against several of the rope turns on the drum.

Title: Flexibly programmed invoicing machine - has programme memory fed with required programme from tape or card store
Inventor: GUCZA ERWIN
IPC: G06F15/02
Filed: 1974-01-17
Abstract: An invoicing machine system with typewriter and desk calculator incorporates a data memory and a programme reader for a tape or card programme reader is followed by an erasable electronic programme memory, which may be in the form of a shift register. The electronic programme memory may be connected to keys on the control unit used to call up and start a programme; this permits any programme to be read into the programme store from a programme reader extracting from a tape or card memory rather than the need to have a series of interchangeable fixed programmes.

Title: Oscillatory signal generator - using phase locked loop techniques uses reference generator and comparator
Inventor: MENKES ELCHANAN DOVE
IPC: H03L7/191
Filed: 1974-01-21
Abstract: A signal generator may be formed so that the output signal is exactly equivalent to a reference frequency, or a multiple of it. Thus the technique may be used to a frequency synthesiser a signal, using a signal of much lower frequency as a reference. A reference oscillator is established and its output is connected to the input of a comparator. The output of the comparator is used to control the frequency of an oscillator, which provides the required output and is also fed to the other input of the comparator, after it has been divided by an appropriate number 'N'. Thus if the output frequency from the oscillator is 'NF', and the reference frequency is 'F', the output from the comparator will be at equilibrium, and no charge shall be required at the oscillator.

Title: Pneumatic mail transport container - retracted from dispatch station by deflecting retaining lever radially outwards
Inventor: LEHMANN HERBERT
IPC: B65G51/26
Filed: 1974-04-17
Abstract: A station of a pneumatically operated mail distribution network is placed at the lower end of a vertical tube section. A tubular container which is ready for dispatch is inserted into the transport tube by pushing it vertically upwards past a protruding wedge shaped spring loaded lever. The spigot pin of the lever is located in horizontal slots outside the tube diameter. As the container is released, it is retained by the knife edge of the lever which is in contact with the inside face of the container flange. By pulling the container downwards it can be retracted again if that should be required. This is possible because the lever is pushed horizontally outwards along the location slots by overcoming the force of a leaf spring.
Patent DE-2424088-A1 (DE)
Title: Two-anchored building-component hoist system - with fixed abutment carried in hoist direction until socket passes anchor zone
IPC: E04B1/35
Filed: 1974-05-17
Abstract: The tractive hoisting of building structure components involves suspending the load on traction members by hydraulic presses or other hoist appliances working in stages, with two anchoring units rhythmically moved on each member, one for anchorage of the member relative to the hoist appliance concerned, and the other relative to a fixed abutment during the return thrust. The traction members comprise steel bars with ends interconnected by sockets. While the connecting sockets are passing through the anchoring area temporary unloading of the traction members is prevented by the fixed abutment being carried along in the hoist direction until the connecting socket has passed the anchoring area, whereupon the anchoring unit concerned is reapplied below the connecting socket.

Title: Working platform support for building exterior - runs around edge of roof on array of small air cushions
Inventor: COX ERIC WILLIAM
IPC: B60V3/02
Filed: 1974-08-05
Abstract: The support crane for the working trolley, suspended from the crane down the outside of the building, rests on an array of small air cushions.

Title: Multi-layer fibrous loudspeaker membrane - has basic membrane reprocessed to add fibrous layers of different density and material
Inventor: ROEDEL FRIEDRICH DR
IPC: H04R7/12
Filed: 1974-10-23
Abstract: The multi-layer fibrous loudspeaker membrane has a basic fibrous membrane press formed into its required shape, e.g. conical, oval, curvilinear etc. and then a further layer built onto it. This further layer is also fibrous but may be of a different fibre material, a different density and/or a different thickness. The reinforcing layers may have additional ribs or curves. The advantage of this two stage production process lies in its allowing the elastic properties of the membrane to be adjusted more easily and more precisely. In one embodiment only a part of the basic core (12) of the membrane (10), namely, that region near the point of the core, is provided with reinforcement (14) to about 2/3rds of the membrane height.

Abstract: Process for recovering a dimethylnaphthalene (DMN) fraction, contg. the 2,6-isomer (I) as main components in the form of DMN complexes, comprises adding to a DMN isomer mixt. contg. (I) opt. together with other hydrocarbon a complex former i.e. nitro derivs. of 2,6-naphthalenedicarboxylic acid, trimellitic anhydride or 2-chloro-5-nitrobenzoic acid, so as to form a solid mixt. of DMN complexes concentrated in (I). The DMN isomer mixt. is pref. liq. (I) may be oxidised to 2,6-naphthalenedicarboxylic acid (III) which is used as starting material for polyesters and plasticisers. Other DMN's (e.g. the 1,5- and 1,6-isomers) may be oxidised to diacids and these converted to (III) by Henkel rearrangement. The complex formers have better specificity for (I) than those already proposed and form 1:1 complexes; also since their solubility in DMN is low material losses are reduced.
