Title: Blood pressure pneumatically operated measuring devices
IPC: A61B5/022
Filed: 1971-10-15
Abstract: 1310220 Electro-medical apparatus L'ELECTRONIQUE APPLIQUEE 15 Oct 1971 [15 Oct 1970] 48151/71 Heading G1N Information concerning the normality or abnormality of the blood pressure condition of a person is provided in the form of a pre-printed ticket which is selected according to blood pressure measurements, e.g. systolic and diastolic pressure measurements, made when the person inserts his arm through a pneumatic sensor which provides an analogue voltage output to an analysising circuit. As shown a pressurized pneumatic sensor 1 and a converter 3 provide a voltage varying with the blood pressure pulses superimposed on the pressure value applied to the sensor which decreases linearly via leak 26. This voltage is applied to an integrator 9 and a differentiator 10. The amplitude of each output pulse of the differentiator 10 is stored at 11 and causes the amplitude of the previous pulse to be transferred to a store 12. Successive outputs of these two stores are compared at 14 and the two charges in sign (from positive to negative and subsequently from negative to positive) of the differences in amplitude detected in a cycle of operation are detected respectively at 15 and 20 which in turn enable respective gates 16 and 21. When these gates are enabled they allow the instantaneous value at the output of integrator 9 to be applied to comparators 17 and 22 respectively. When gate 16 is enabled the integrator output represents the systolic pressure amplitude, the diastolic pressure amplitude being represented when gate 21 is operated. The comparators 17, 22 compare  their inputs with respective reference 18, 23  which may be set up according to various physical characteristics of the person, Fig. 9 (not shown). The results of each comparison are stored in respective one-shot circuits 19, 24 which control a logic circuit for a ticket distributer 2, which is operated by a zero detector 8. The distributer may have two pre-printed ticket compartments for normal and abnormal pressure indications, Fig. 7 (not shown), or four compartments for normal or abnormal systolic and normal or abnormal diastolic pressure indications, Fig. 8 (not shown).  The circuitry 11-21 may be analogue, Fig.5 (not shown), or a combination of analogue and digital, Fig.6 (not shown).

Title: Improvements in apparatus for manufacturing Tubular Film from Synthetic Organic Thermoplastic Materials
Inventor: THORDARSON JON
IPC: B29C48/10
Filed: 1966-10-27
Abstract: 1,153,604. Producing tubular films. J. THORDARSON. 27 Oct., 1966 [27 Oct., 1965], No. 48251/66. Heading B5B. As shown in Fig. 1 an apparatus for producing tubular film 2 comprises an extrusion head 1 provided with an annular extrusion orifice through which synthetic organic thermoplastic material is melt extruded in the form of a tube 2a. Surrounding the extrusion orifice is an air blower in the form of a box 3 having an annular slot 3a through which a stream of cooling air is directed upwards around the extruded inflated tubular film. The tubular film is drawn upwards in the usual manner by means of a pair of nip rolls 4a, 4a which also prevent the air or other gas with which the tubular film is inflated from escaping. The film is inflated by introducing air into the interior of the film at constant pressure through the pipe 15 and the hollow members 11 and 12 supporting a cooling column 6 positioned inside the film and through the cooling column itself. The air flows out of the bottom of the cooling column 6 and upwards between the cooling column 6 and the tubular film (as shown by the arrows 5) until the film is inflated to the required degree, after which only sufficient air is introduced into the tubular film to replace the very small amount of air leaving out of the flattened film between the pinch rolls 4a. A fan 7 driven by an electric motor 18 near the top of the interior of the column 6 (Fig. 2) draws hot air from the upper portion of the interior of the inflated tubular film through the inlets 19 and then impels it downwards inside the column 6 over an axial internally cooled tubular cooling element 17 as shown by the arrows 5<SP>1</SP>. Stationary baffles 9 inside the lower portion of the cooling element 6 impart a rotary motion to the cooled air travelling downwards through the lower portion of the column and thereby cause the air the rotate a nozzle 8 rotatably mounted on the lower end of the column. The nozzle 8 is provided with one or more radial outlet ducts which direct cooled air on to the inner surface of the tube 2a so that the latter is internally as well as externally cooled. The air is then drawn upwards between the column 6 and the inflated tubular film 2 and again enters the inlet ports near the top of the column 6. The shaft 11 which extends through the core 12 of the extrusion head accommodates inlet and outlet ducts 13 and 14 for the circulation of cooling water through the cooling element 17 and electric power leads 16 for operating the fan 7.

When the spigot 18 is aligned with the orifice 12 the tabs 21, 22 align with holes 24 in the base 10 so that the button 3 may be depressed to cause the spigot 18 to open the container valve and discharge a spray through the nozzle 20. In the second position the tabs 21, 22 are opposed by a solid portion of the base 10 so that the button cannot be depressed. The stem 29 of a second container engaging the tube 25 causes it to slide in the button into engagement with the stem 5 so that the second container is filled. The tube 25 and button are returned after actuation by the resilient portion of base 10. A tear tab 13 is provided on the body 2. It is stated that the button may be linearly moveable or tiltable between the two positions instead of being rotatable.

[Also in Division C7]  Metal-gas alloys (e.g. N 2 -containing iron alloys) are cast from a reservoir maintained in an atmosphere containing an active gas that dissolves in the molten metal and an inert gas. From the reservoir the molten metal is cast into a mould maintained in a second atmosphere of the active gas or a mixture of the active gas with an inert gas, in which the pressure or partial pressure of the active gas is greater than the partial pressure of the active gas in the first atmosphere about the reservoir, thereby inhibiting degasification of the metal-gas alloy during soldification. In Fig. 1 melt is held in a reservoir 1 within a hermetically sealed housing 2 containing the first atmosphere. A riser tube 3 communicates with a mould 4 above in a second hermetically sealed housing 5 containing the second atmosphere. Each housing 2, 5 is supplied with gas from reservoirs 8, 9 respectively. To cast the melt the total pressure in housing 2 is raised above that in housing 5 and a valve 7 opened so that the melt flows upwardly into the mould 4. Alternatively, the melt can be gravity cast if a bottom-pour reservoir os located above the mould.
