Abstract: 1506050 Vehicle head-lamp wipers B PETERSSON 16 July 1975 29867/75 Heading A4F To prevent lift-off of a reciprocable vehicle headlamp wiper blade 9 from the head-lamp glass or lens 2, the blade is guided by a guide 6 which has a  portion fixed to extend substantially centrally across the lens 2. As shown in Figs 1 and 2 the guide 6 is a rigid wire mounted between supports 4, 5 and guiding a sliding element 7 which supports the blade 9 and its holder 8, a rigid pull rod 10 attached to the element 7 and driven by a motor or a handle (not shown) imparting reciprocating motion to the blade. In a modification Fig. 3 (not shown) the rigid rod 10 is replaced by a tube (12) surrounding the guide wire, the tube (12) being attached to a manually-operated handle Fig. 4 (not shown) which can be pulled or pushed to drive the blade 9 across the lens 2. Alternatively a pedal or a motor may be used to reciprocate the blade. In an alternative embodiment, Fig. 6 the sliding element 21 is guided on a profiled guide element 18 (only a small part of which is shown) which includes a channel having guide surfaces 20 for guiding a drive rod 23 attached by rivets 26 to the sliding element 21.

Title: Method and apparatus for measuring the density of a fluid
IPC: G01N9/00
Filed: 1970-06-19
Abstract: 1319313 Measuring density CANADIAN PATENTS & DEVELOPMENT Ltd 19 June 1970 [20 June 1969] 29883/70 Heading G1S A densitometer comprises an air jet nozzle 1, Fig. 1, which blows test air into a receiver tube 2 spaced at a particular distance from the jet, both jet and receiver being surrounded by a stationary or flowing gas whose density is to be determined. The reading of the manometer 4 will be related to the gas density. In Figs. 2 and 3 (not shown) graphs illustrate the use of the apparatus at various test air pressures for different nozzle and receiver spacings and for different gases to be measured. In Figs.4-6 (not shown) the nozzle and receiver tubes are surrounded by a cylindrical housing (18) reducing cross flow interference and are supported by radial stays. In Fig. 7 (not shown) the housing is a fluid or gas permeable mesh, protecting the tubes from solid particles and closed at one or both ends by a mesh wall. In Figs. 8-10 (not shown) the tubes are disposed between two plates which may be plane or curved. In Figs. 11, 12 (not shown) the tubes project through and only just above the surface of a plane or curved supporting plate which also guides the flowing gas. The embodiments of Figs. 13-17 (not shown) are concerned with comparators checking the supply pressure and comparing the pressure with the pressure received in the receiver tubes of densitometers. In Fig. 18 the distance X of the nozzle 51 from the receiver 61 is adjusted by a micro-meter arrangement.

Filed: 1975-07-16
Abstract: 1511662 Measuring electric field strength KANSAI BRANCH OF JAPAN PSYCHIC SCIENCE ASSOCIATION Inc and H UCHIDA 16 July 1975 [16 July 1974] 29908/75 Heading G1U An unspecified field, said to be produced by a variety of sources, is detected by a conductive probe member 2 connected to the input of a very high input impedance (e.g. 10<SP>9</SP>#) DC amplifier 13, if necessary via an interference suppressing filter 12, the probe being shielded from external fields. The amplifier comprises main and meter amplifiers which together exhibit variable sensitivity and zerosetting. To detect the direction of the field source, the probe is placed in the field and the meter set to zero; by moving the probe, the needle deflects positively or negatively thereby indicating the source direction, the correspondence between positive deflection and moving towards or away from the source being a function of the source. A wide variety of sources may be detected i.e. electromagnetic waves, light bulbs - either A.C. or D.C., whether on or off, organic materials, gases, offensive odours etc. The output from the probe is also a function of the rate at which the probe is moved in the field.

Tentering.-Relates to rnaans for moving the tenter rails transversely in accordance with the position of the cloth selvages so as to obtain correct feeding to the clips and comprises right and left handad screwed spindles cross-traversing the tenter rails, the spindles being rotated by reversible electric motors put into operation through relay circuits controlled by a pair of feelers engaging opposite edges of the cloth, the motors being put out of action not only when the cloth is central with respect to the rails but also when the cloth breaks. Each feeler a is carried on the corresponding tenter rail q by a pivoted support b to which is attached a weighted arm d tending to keep the feeler in engagement with the cloth selvage. A spring contact arm c attached to the support b engages with one of two contacts e, f so as to close one of two relay circuits operating motor switch mechanism and cause the rotation of the corresponding motor m in one or other direction to adjust the tenter rail according as the position of the selvage of the cloth varies. The contact f is normally connected to a contact j by a spring strip i, but should the cloth break, this strip is pushed away from the contact j by a roller h carried by an arm attached to the pivoted support b, so that the circuit is broken and the motor is not actuated. The motors m move the tenter rails through gearing n and right and left handed screwed spindles o, p.

Title: Device for separating from a time modulated multi-channel pulse train a pulse train belonging to a desired channel and converting the latter pulse train into a duration modulated train
IPC: H04J3/04
Filed: 1950-12-19
Abstract: 716,371. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L.M. ERICSSON. Dec. 19, 1950 [Dec. 19, 1949], No. 30909/50. Class 40 (5) The separation from a time modulated multichannel pulse train of the pulse train of a particular channel and its conversion to a duration modulated train is effected by a single multigrid valve. In Fig. 1, gate pulses of channel repetition frequency and the whole train of positive going time modulated pulses of all the channels are applied to the control and suppressor grids respectively of a pentode valve 1 which selfbiases to cut-off between gate pulses. Anode current pulses equal in duration to the time between commencement of a gate pulse and the time of the channel pulse occurring are produced in the anode circuit due to the channel pulse immediately producing a negative blocking bias on the suppressor grid resistance-capacitance circuit 2, 3, the time constant of which is made of the same order of value as the channel repetition period. A demodulated output is therefore derived from a low pass filter 5 connected to the anode. By suitable timing of the gate pulse applied to the control grid any channel may be selected and demodulated:
