Title: Paper holder pressure rollers for ink jet printer - have porous insert to absorb undried ink and thereby prevent smudging
Inventor: ROSENSTOCK GUENTER DIPL ING
IPC: B41J13/20
Filed: 1977-12-06
Abstract: The pressure rollers on the paper holder have a plastics body (3) with a circumferential recess (4) housing an absorbent ring which rests on the surface of the paper. The ring is able to absorb any wet ink and thereby helps to prevent smudging. The ring is made from e.g. felt, porous rubber, sintered material or rigid foam material. Instead of using such a porous ring insert, the complete roller can be made of such absorbent material.

Patent DE-2813042-A1 (DE)
Title: Ensuring uniform wall thickness of plastics deep-drawn containers - by reducing friction between film to be moulded and pre-draw plug with use of ultrasonic vibrations
IPC: B29C51/04
Filed: 1978-03-25
Abstract: Machine for deep-drawing heat-plasticised film has a pre-draw plug provided with means adapted to reduce friction with the film. These means generate ultra-sonic vibrations. The pre-draw plug has the purpose of evening the wall thickness of the intended moulding, usualy a container. Without it, the section of the moulding near the top rim would be drawm whilst the bottom would be drawn so much that it would be relatively very thin. This shortcoming being aggravated by the fact that heat-softening a plastics film increases its friction against a pre-drawn plug, it has been found advantageous to fit the latter with ultrasonic-generating means whose action substantially reduces this friction thus facilitating more even distribution of moulding cpd. over the area affected by the operation of the plug.
Patent DE-2813833-A1 (DE)
Title: Individual speed control for in-line conveyor belts - is used to bunch flat overlapping objects on conveyor
Inventor: MATTIEBE GUENTER
IPC: B65H29/66
Filed: 1978-03-31
Abstract: A conveyor system which carries flat and overlapping objects such as bags, includes two independent conveyor belts (1, 2) so that the flow of objects is transferred from one belt (1) to the other belt (2). During the transfer, the overlapping objects are bunched together so tht a spacing is produced between each individual bunch. The spacing is produced by running the second conveyor belt (2) at a slower speed and by stopping the leading end of the bunch with a clamp rail (3). Speed sensors (4, 6) which monitor the two velocities provide the input signals for the process regulator (7).

Fe) in crude (II) (these ions catalyse alkylation of the aromatic hydrocarbon solvent by (II)). (III) is used at 2-3.5 moles per mole metal cpd. Generally (II) contains 10-20 ppm metal as 50-100 mg. (III) per kg (II) is usually sufficient.

Title: Tennis racket grip for individual fit - has plastics mass shaped by player's hand and bound up when set
Inventor: KRATOCHVIL PAVEL
IPC: A63B60/08
Filed: 1978-04-12
Abstract: The tennis racket handle comprises a core and an outer sleeve. The core forms a unit with the racket shaft but has a smaller cross-section. The sleeve is formed from a plastics mass which is applied to the core and then shaped by the player himself when he grips and holds the handle. Once the plastics mass has hardened the shaped grip can then be wrapped with a resilient absorbent non-slip grip band (8) which fits round the shaped impressions and adheres to the grip surface. The handle grip produced thus accurately fits the player's hand.

Title: Ignition system for IC engine - has flip=flop in closing angle control device, so that integrator output signal zero level is reached earlier
Inventor: FRITZ ADOLF
IPC: F02P3/045
Filed: 1978-07-29
Abstract: The system has a contactless generator followed by a threshold switch and generating a control signal with a specified keying ratio. The control signal operates the closing angle control devices with a monstable flip-flop. An integrator has a signal source each for an upward and downward integration. The two signal sources are so controlled by the control signal and the flip-flop that the integrator output signal zero level is reached at the end of an integration cycle earlier by the flip-flop tripping interval than it would have been reached if controlled by the control signal alone.

Title: Synchronous machine with static converter - has three=phase excitation field rotating in opposite directions for upper and lower speed ranges
Inventor: BENDEL REINHOLD ING GRAD
IPC: H02P25/024
Filed: 1978-12-15
Abstract: The synchronous machine has its stator terminals connected to a self-commutated static converter. The 3-phase excitation field rotates in the same sense as the desired direction of rotor rotation in the lower speed range whilst in the upper speed range it is switched over to rotate in the opposite direction to the desired rotor rotation. The switch over in the 3-phase field direction occurs when the stator voltage is equal to the sum of the minimum commutating voltage and twice the standstill stator voltage or when the stator frequency is equal to the sum of the minimum commutating frequency and twice the rotor frequency.
Patent DE-2855593-A1 (DE)
Inventor: PLEY JOSEF
IPC: H01B13/02
Filed: 1978-12-22
Abstract: The stranding elements (9) are stranded with a mutual loop in a reversing manner to form a bundle (10). In order to avoid difficulties in pulling off the stranded assembly, the bundle is guided such that it is free of twists and curves and is finally pulled off in a linear manner using a controllable tensile stress. The stranding assembly guide and the pulling-off element are combined in the device to form a unit (5) which forms the fixing-point region of the stranding. This unit is arranged at the shortest possible distance downstream of the stranding nipple (4). <IMAGE>

Title: Reaction calorimeter measuring reaction enthalpy in closed vessel - determines heat flux in wall considering difference in heat supplied and discharged
Inventor: BAHNER FRIEDRICH DIPL PHYS
IPC: G01K17/00
Filed: 1978-12-27
Abstract: In a reaction calorimeter used to determine the reaction enthalpy of chemical or thermal reactions carried out in an enclosed vessel, the heat flux flowing through the wall of the reaction vessel is measured. The heat energy absorbed or released in a chemical reaction is determined or the thermal reactions when heating or cooling a particular substance are measured. An accurate determination of the losses due to radiation is effected. Specifically the substance being analysed is heated in a vessel and the casing provided with a heat flow meter. The difference between the heat energy supplied and discharged as a function of the temp. of the vessel is recorded.

Title: Tumble-dryer with air-cooled condenser - having overflow connection from condensate storage chamber back to condenser
Inventor: FEY HANS DIPL ING
IPC: D06F58/24
Filed: 1979-08-18
Abstract: A tumble dryer for laundry has an air-cooled condenser to extract moisture from the drying air, which collects in a drip container beneath the condenser. The container is periodically emptied by an automatic pump which lifts the condensate to a high level storage tank in an easily-accessible chamber behind the control panel. The chamber has a drain outlet to take any overflow from the tank back into the drip container, which stops further condensate collection and activates an alarm signal if it becomes overfilled. This is a simple, reliable and relatively inexpensive arrangement for monitoring the condensate level.
