G. or E.C.G., are processed by an analyzer containing a voltage level switching device to exclude abnormal signals from the counter or evaluating device. In one embodiment Fig.3 (not shown) a threebank rotary switch feeds the detected signals through a differentiater and the resulting slope signals are integrated and fed to storage capacitors and a summing device. If these signals fall within the limits of the "level switch" they are passed on to a counter. In an alternative arrangement the rotary switch and store is replaced by a multi-head tape recorder Fig.4 (not shown). In a further arrangement Fig.5 (not shown), the signal level controls a servodriven potentiometer adjusting the voltage level switch so that signals are not registered if the magnitude, in an immediately preceding time interval, was outside the limits. A "programmer" may determine the period for which measurements are taken and vary stimula to an organ by e.g. light, sound, an electric skin stimulator, or varying the pressure in a sphymanometric cuff Fig.2 (not shown).

Abstract: 1,253,062. Flame-resistant polyamide compositions. MONSANTO CO. 8 Nov., 1968 [9 Nov., 1967], No. 53112/68. Heading C3R. Flame-resistant compositions comprise (a) a polyamide, (b) at least 20 vol. per cent of an inorganic filler, and (c) 8 to 35 wt. per cent of a polyhalogenated aromatic hydrocarbon other than pentabromotoluene, or a mixture thereof with an antimony oxide. The polyamide may be a polymer of a mono- or bis-lactam or a polycondensate of a dicarboxylic acid and a diamine, suitable monomers being exemplified. It may be blended with another polymer, e.g. polypropylene, polyethylene, polystyrene, polyacrylonitrile, polybutadiene, acrylonitrile-containing rubbers, styrene-acrylonitrile copolymers or polyphenylene oxide, and may be crosslinked, e.g. with polyethylene imine or tetra- (3-aminopropoxymethyl)-methane or through #Si-O-Si#links. Preferences are stated for the size, shape, hardness and solubility of the filler. Numerous inorganic (defined to include carbon blacks) fillers are mentioned with particular emphasis on the use of couplertreated fillers in anionic processes with extensive description of such couplers and processes. Optional ingredients specified are other fireretarders, e.g. hydrocarbyl or substituted hydrocarbyl phosphates, stabilizers, dispersing aids and mould releases, e.g. tetra-alkyl orthosilicates, dyes and pigments. The flame resistance of the products may be further improved by water-equilibration, e.g. by immersion in boiling water for 3 days. Comparative examples show that even 17 % filler is insufficient to achieve flame resistance even with 35% flame retardant. The compositions may be moulded directly or prepared as moulding powders. A mat of (b) may be impregnated with a solution of (a) + (c). Articles from a composition with a high content of a metal filler may be electroplated.

Abstract: 1,259,075. Making relief printing plates. W. R. GRACE & CO. March 31, 1970 [June 6, 1969], No.15302/70. Heading G2A. Support sheets for making relief printing plates are passed through an automatic machine in which, at successive stations, they are coated with a liquid photo-curable composition, exposed to actinic light through an image-bearing transparency, cured, etched by ultrasonic energy, washed, dried, and further cured. As shown, a sheet is drawn from a supply stack 40 housed in a shell 14 by a suction conveyer 38 and passed on to a platen 44, on which it is held flat by vacuum means Figs.3 and 4 (not shown). It is now coated with a liquid photo-curable composition from a dispenser 46, the composition being stored in a jacketed tank Fig. 5 (not shown) in which it is constantly agitated and maintained at a suitable temperature. It is dispensed by a pump via a tube (108) having a number of dispensing openings (158), the tube being mounted on a carriage which traverses across the sheet. A doctor blade attached to the carriage levels the applied liquid to a uniform layer. The sheet is now transferred by suction means from platen 44 to an exposure platform 52, the transparency which is to be copied being supported from a plate 54. The transparency may be spaced from the liquid layer on the sheet, or in contact therewith. Exposure is now effected by illuminating from above, through the transparency, by an actinic light source (202) Fig.12 (not shown). The support sheet with the photo-cured layer is now lifted from platform 52 by suction means, its movement being changed from horizontal to vertical, and is carried past a further exposing unit 60, where it receives further photo-curing from behind, so as to complete the photo-curing action in depth throughout the layer of the material. The sheet is now transferred to a hanger 62 moving along a track 64 as far as a station 66, where it is lowered into an etching bath 68. The liquid in the etching bath may be continuously monitored as regards temperature and concentration, and is activated by ultrasonic transducers Fig.18 (not shown). The sheet is now removed from the etching bath, and carried further along track 64 to a wash tank 72, in which it is washed by jets of water under pressure, and then elevated into a drier 76. A slide 74, which has previously been retracted, is moved into its operating position, and the sheet is dropped out of the drier on to the slide. This guides it on to a further slide and thence on to a table 80. Here it is initially moved in the direction of arrow 82, then firmly positioned on table 80 which is then moved in the direction of arrow 84. During this latter movement the sheet receives a final photocuring from a series of light sources below the table, and the sheet is then transported in the direction of arrow 86, and dispensed from a platform 34 on to a trolley 88 by means of which the sheets may be transferred to a printing press.

[Also in Division H2] In a photo-electric range finder utilizing a modulated light beam projected on to the target, the output of the photo-electric receiver is switched in synchronism with the beam modulation to a storage device, whereby the stored sum of interfering signals is substantially zero. As applied to an automatically focused photographic camera 18, echo rays are directed on to photo-conductors 9, 10 which are connected in a phase-sensitive detector, see below. The output of that detector controls a motor M which (1) moves the photo-conductor assembly until the motor stops, i.e. the photoconductors receive equal light fluxes and (2) moves the adjusting ring 20 of camera objective 19. Phase-sensitive detector, Fig. 2.-Photo-conductors 9, 10 give rise to an A.C. voltage across resistor R5 of differential amplifier T1, T2 (if receiving unequal light fluxes) in phase or in anti-phase with the modulation of the light; such voltage is amplified and fed to a switching circuit T4, T5 controlled by a multivibrator T6, T7 which also affords the modulation of lamp 1. A series of positive-going or negative-going pulses ensues to control motor M (see Division H2) so as to balance the outputs from the photo-conductors.
