Title: Polyamide fibres - contg isocyanurate - alkylene oxide adduct as antistat and an alkyl phenol and thiodipropionate as
Inventor: WELLS RODNEY LEE
IPC: C08K5/17
Filed: 1973-07-28
Abstract: Polyamide fibre is produced by melt extruding a polyamide into a quenching medium and stretching the resulting filament, the polyamide contg. (A) 1-10 wt.% of an antistat which is a tris(beta-hydroxyalkyl) isocyanurate-alkylene oxide adduct of formula : (R and R' are H, CH3 or C2H5, and r, s and t are integers 31-200). (B) >=0.5 wt.% based on antistat of a phenol of the formula : (R1 is H or a 1-5C alkyl and R2 and R3 are 12-18C alkyl) and (C) >=0.5 wt.% based on antistat of a cpd. of formula : R4OOC.CH2CH2-S-CH2CH2.COOR5 (R4 and R5 are 8-18C alkyl). The phenol, e.g. 2,6-dioctyldecyl-p-cresol and cpd. (C), e.g. dilauryl thiodipropionate, reduce the occurrence of nubs in the fibre which the antistat tends to generate.

Title: Frequency multiplying circuit - has multiplication factor which can be freely chosen
Inventor: KIENCKE UWE DR
IPC: B60T8/172
Filed: 1973-08-29
Abstract: A timing frequency is applied through a stepping down device to a counting input of a forward counter, whose reading can be transmitted by each input pulse to a register, and erased. The counter reading can be repeatedly counted by the timing frequency. The stepping down device division ratio is equal to the input frequency multiplication factor. The frequency to be multiplied is applied to an input gate between the forward counter and the register. A D-flip-flop operating synchronously with the timing frequency is connected to the counter resetting input.

Title: Brake hold for changedown stability in heavy vehicle - with manual hold button to maintain brake setting for set time interval
Inventor: OESTERLE ULRICH DIPL ING
IPC: B60T7/04
Filed: 1973-10-02
Abstract: The brake pedal linkage is fitted with spring loaded pneumatic/hydraulic cylinder which normally returns the brake pedal to its non operative position when the foot is lifted. In heavy vehicles when travelling downhill the engine can overrun when changing down, especially with no- or limited synchromesh. The invention provides a manual hold control for the brake which retains the brake pedal setting for a set time interval after the foot is lifted, controlled by a throttle in the pneumatic/hydraulic line. During the time interval the brake pressure can be increased by further pedal pressure. The driver is therefore able to control the changedown with greater accuracy.

Title: Nozzle for hand-held blow dryers - has perforated walls and cover plate to adjust supply of hot air
Inventor: CERCONE DANIEL
IPC: A45D20/12
Filed: 1974-01-05
Abstract: The hair dryer nozzle has a cylindrical portion for attachment to the hand-held dryer and a nozzle member which has opposite side walls converging in the flow direction with several apertures to allow passage of part of the air current in a direction inclined to the longitudinal axis of the nozzle. The nozzle contains at least one adjustable cover and air deflector plate which can be swivelled from an end position in which it covers the apertures into a second end position in which it projects into the air current in the nozzle so that part of the air current is deflected to the openings. This simple means allows part of the air current to be deflected so that the supply of heat from the mouth of the nozzle can be reduced without increasing the distance of the apparatus from the hair.

Title: Building-up tyre tread - by prestretching tyre strip on drum then transferring to lower layers on assembling drum
Inventor: NAEDLER HEINRICH
IPC: B29D30/24
Filed: 1974-04-26
Abstract: A method of building up the tread of a tyre uses a variable diameter drum; before the tread strip is place on this drum, its length is checked for agreement with the circumference of the underlying layers and is corrected as follows it is first placed on a second variable-diameter drum, adjusted to fit it, the ends are then joined together, then the resultant tread hoop is stretched, transferred onto the layers, on the first drum and pressed on. The second variable diameter drum is mounted coaxially to the first drum esp. on the same shaft. The tread strip is stretched by axially forcing in a cone to expand the segments, using a hydraulic ram and cam path. A variable diameter ring with internal suction cups lifts the stretched strip from the second drum and transfers it to the first drum.

Title: Photoelectric reader unit for optically scanned patterns - has luminous diode and circular photocell
Inventor: BRUCH WALTER PROF
IPC: G06K7/10
Filed: 1974-05-28
Abstract: The luminous diode (5) is placed in the inner opening of the circular photocell (4) and both are designed as semiconductor bodies on the same sublayer. Between the luminous diode and the photocell there is a circular shield (6) which is so dimensioned that light from the luminous diode cannot reach the photocell directly. The unit can have a common terminal for the luminous diode and the photocell and two other terminals (9, 10) for the diode and the photocell. The photocell can be thicker than the luminous diode. This prevents light from the diode from reaching the photocell directly.

Title: Bed frame with hinged seat - has toothed segment attached to back and ratchet attached to bed frame
Inventor: GREINER OTTO
IPC: A47C20/04
Filed: 1974-06-10
Abstract: The bed floors consist of hinged-together seat and backrest parts. With changing pressure increase on these parts, the backrest part is pivoted up or down and simultaneously, to avoid excessive, undesired lowering of the rear end of the seat part, executes a sliding movement upward. A fixing device has a toothed segment attached to the back part and a ratchet attached to the bed-frame. The segment's teeth are fitted to the periphery so that all apertures between them correspond to the direction of motion of the ratchet. The upper ends of the teeth are bent over in a roof-like shape, enabling the ratchet to slide in easily. The amount of pivoting of the teeth has to be determined empirically on a prototype of the bed, and cannot be calculated.
Patent DE-2442977-A1 (DE)
Title: Treatment of flexible webs with liquids cong. reagents - including preheating of web before impregnation
Inventor: WITTKE WALTER
IPC: D06B19/00
Filed: 1974-09-07
Abstract: Sheet matls. in web form, e.g. paper, pulp, fabric, felt or other non-woven matls. are impregnated with substances in soln., dispersion or emulsion form after preheating to temps. substantially higher than that of the treating medium. Impregnating liq. penetrates more deeply and more rapidly into the inner structure of the web. In addn. the process has appreciable economic advantages, since the preheating can be used e.g. to dry, heat set or preshrink the web. When heat-sensitive matls. are being applied, an appreciable shortening of the coagulation time is achieved and economy in heat at this stage is achieved.

Title: Weighing and blending fertilisers - with means of varying blend using conical screw mixer with weighing mechanism
Inventor: SCHEER GERHARD
IPC: G01G19/24
Filed: 1974-10-09
Abstract: Plant for weighing and mixing solids which can be scattered esp. for creating various blends, consists of a feed vessel mounted above ground level which can act as or be combined with mixer, one or other being mounted on a weighing mechanism. A converying mechanism is included and the mixer is connected to a scale via a weigh beam. The weigh beam is sufficiently high to allow a vehicle underneat to receive a charge of matl. The feed vessel can act as the weigh vessel with conveyance to the mixer, or the mixer itself can be mounted on the weight beam with a conveyor feeding it. The conveyor has a feed hopper with some form of metering device on it. The plant is intended for use in agriculture to blend fertilisers. Depending on soil conditions and crops, different blends are needed. The device a allows the blend recipe to be altered simply by weighing in the components and then mixing them, finally discharging into a vehicle.
