Title: Vaporising humidifier with casing in three sections - has hollow tapered support feet on middle section
Inventor: BRUNE PIT JUERGEN
IPC: F24F6/04
Filed: 1973-12-05
Abstract: The humidifier has an upper section which contains the air inlet and discharge grilles, a lower section which forms the water container and an intermediate section which is a carrying plate supporting all the internal components.

Title: Record player pick up arm based on hinged piece - is held on a carrier spindle by a spring loaded mounting unit
Inventor: EVANS PHILIP HENRY
IPC: G11B3/32
Filed: 1974-12-11
Abstract: The record player pick up arm arrangement comprises a carrier spindle which can be moved vertically around its axis on the upper end of which a pick-up arm is based, so as to move horizontally around its axis. The improvement on similar arrangements consists in the pick-up arm being based on a hinged piece which can be removed from the carrier spindle. The hinged piece is held on the spindle by a spring loaded device with a mounting which slides over the spindle. The mounting and spring-loaded device work together with the spindle in such a way that the pick up arm can be moved a certain distance on a vertical axis against the spring, which will thenr eturn it to its original position.

Title: Platinum resistance temp measurement linearisation circuit - operational amplifier injects reference voltage dependent current
Inventor: SZEPAN REINER DIPL PHYS
IPC: G05D23/24
Filed: 1974-12-20
Abstract: An operational amplifier (1) dependent upon a reference voltage, injects a current into the platinum resistance (2) functioning as temperature sensor. This increases with the value of the platinum resistance so that the voltage at the platinum resistance becomes linear in relation to temperature. The reference voltage may be pulsed and its value derived by means of a potentiometer circuit. The reference value voltage may be produced through a digital to analog converter. A feedback signal may be produced dependent upon the amplitude for feeding to the digital reference value.

Title: Overstitching machine upper carrier - is continuous band passing in angular path round machine body to save space and reduce moving mass
Inventor: AHNERT PETER
IPC: D05B1/20
Filed: 1975-02-03
Abstract: In an overstitching machine with a side-folding sewing foot and a sewing plate in which two separates powered lower carriers are arranged behind each other, the upper carrier is in the form of a continuous band which runns through an aperture in the sewing foot. A deflecting roller is positioned behind the sewing foot to allow the band to pass at an angle round the machine body. The band is driven from the machine main shaft to pass towards the sewing point. The angular path of the upper carrier band gives space saving in the sewing zone, and allows it to pass under the thread brakes. The lightweight construction of the carrier band also reduces the amount of moving mass.

Title: Pneumatically operated coupling ring - has internal and external tapers to transmit torque or act as friction brake
Inventor: RE GIANPIERO
IPC: F16D67/04
Filed: 1975-11-21
Abstract: The friction coupling assembly connects two concentric shafts. The driving ring is formed by two tapered friction faces which produce a concave internal groove. The coupling disc consists of two parallel plates whose outside tapers match the drive ring tapers. A pneumatic ring tube is placed between the two halves of the coupling disc. When the coupling is engaged, the ring tube is pressurized such that the coupling disc expands axially until torque cna be transmitted by the function tapers. Similar internal tapers on the coupling ring are in friction contact with stationary convex tapers when the ring tube is depressurized, thus it acts as a brake.
