Title: Resilient cap for spring bars on mattress frames - has shortened support webs and plate for material saving and greater resilience
IPC: A47C23/06
Filed: 1976-09-16
Abstract: The cap for the spring bars in mattress frames consists of a rectangular housing (10) open on one side and is supported on the bearing strip (20) of the frame by resilient support webs (13, 14) which originate in the lower wall of the housing and are connected together at their free ends by means of a support plate (17) which together with the support webs (13, 14) are mounted in the open side of the housing (10). The plate and two webs (13, 14) only extend over a part of the depth of the housing whilst the ends (15, 16) of the plate (17) which protrude laterally beyond the webs are adapted for direct connection to the facing upper side of the bearing strip (20). Shortening the support webs and plate saves material and improves the resilience of the housing in the direction of the longitudinal axis of the spring bar held therein.

Title: Axial piston engine with variable angle swashplate - has plate axis of tilt near cylinder block periphery and support plate linked to controls
Inventor: STUHR HANS-WALDEMAR DIPL ING
IPC: F01B3/00
Filed: 1976-12-04
Abstract: The axial piston engine with variable angle swashplate was the axis of tilt (9) of the plate perpendicular to the cylinder axis of rotation but not passing through it, viz. near the cylinder block periphery at the swashplate end, to minimise cylinder unswept vol.

Title: Pulse train data transmission - includes counting pulses and changing polarity at transmission channel input when end of pulse train is detected
Inventor: DOMES RAINER
IPC: H04Q1/442
Filed: 1977-01-10
Abstract: The transmitted information is represented by the number of pulses in a pulse train. Pulses of a pulse train are counted by a counter (ZS1). After the end of a pulse train is recognised, polarity at the transmission channel (g) input is changed and the counter is counted back by a clock pulse train whose frequency is higher than the pulse train fundamental frequency. Polarity at the transmission channel (g) input is restored to its initial state when the counter reaches zero.

Title: Bread bin with sliding shelf - has withdrawable support for loaf when being sliced
Inventor: GAERTNER HANS GEORG
IPC: A47B77/16
Filed: 1978-01-28
Abstract: The bread bin has a sliding shelf which can be drawn out like a drawer and used to support the loaf whilst it is being sliced, or the slices, whilst they are being buttered. The shelf is hinged to a support at its inner end so that when it is pushed into the bin the shelf swings downwards.

Title: Phosphoric acid or phosphate(s) prodn. - from chlorine-contg. rock phosphate or apatite by acid digestion followed by oxidation
Inventor: BERGE TORKJELL
IPC: C01B25/01
Filed: 1978-03-09
Abstract: Process comprises initial leaching with mineral acid followed by further processing of the resulting mixt. During or after the leaching step at least one strong inorganic oxidising agent is added in an amt. sufficient to completely oxidise the organic and sulphide components of the phosphate, and to completely oxidise the chlorine component to Cl2, the Cl2 thus formed being removed by the ventilation system of the process. Process is simple and economical and enables high-chlorine raw materials to be used which with conventional processes gives rise to corrosion problems. In an example Kola phosphate contg. 0.4% Cl is digested with HNO3 while air is passed through the appts. In the absence of added oxidising agent, the chloride content of the reaction mixture is 0.11% and the waste gases contain 0.5 g HNO3/kg P. When NaClO3 is added, the chloride content of the mixture is 0.012% and the waste gases contain 3.1g HNO3/kg P.

Title: Self-protecting wound capacitor - with axially shrinkable dielectric and low-melting face contact layer
Inventor: BAUMGAERTNER ARMIN DIPL PHYS D
IPC: H01G13/00
Filed: 1978-06-14
Abstract: Wound capacitor inside a not air tight enclosed caing has a dielectric which can shrink in the axial direction when overheated and has face contact layers which join the metallised lining of the foils to the terminals. The lining has a high square resistivity of 4-6 ohm and the contact layer, pref. sprayed lead-tin, extends over only a part of the face area. Capacitor has a very simple design and provides reliable protection against overheating without requiring any additional security fitments. The shrinkage causes a detachment of the face contact layers and any remaining contact is burned out by the high current density.
