IPC: E06B3/16
Filed: 1967-01-25
Abstract: 1,211,882. Curtain walling, mullions. ASTRALITE Ltd. 1 Dec., 1967 [25 Jan., 1967], No. 54769/67. Divided out of 1,211,881. Headings E1J and E1K. A structural assembly such as curtain walling comprises two juxtaposed frame members 10a, 10a, having a closed transverse section profile comprising a main body portion 10a and an outward extension 16 including a root portion 16 and a return portion 28 spaced away from and overlying part of the body portion.

Title: A touch detecting teaching machine
Inventor: CLEARY ALAN
IPC: G09B7/06
Filed: 1969-11-13
Abstract: 1286823 Teaching machines BEHAVIOURAL RESEARCH & DEVELOPMENT Ltd 13 Nov 1969 55602/69 Heading G5G A teaching machine is such that the user is presented with several items of visible information on touch-sensitive screens and an audible instruction or question correct response to which involves touching one of the screens, an audible indication being given if the right screen is touched. The invention requires that the machine makes a random selection of which screen is to be the right one before issuing the audible instruction to the user. The machine (Fig. 1, not shown) is otherwise similar to that of Specification 1,160,702 and may. employ the touch-detecting means Specification 1,160,703 and performance computer of Specification 1,160,701. The visible information consists of picture 34a, 34b, 34c on a card 32 which, when inserted in the machine, will present the user with one picture on each of three screens. The card also carries three sound tracks 36a, 36b, 36c each relating to one of the pictures-e.g. track 36c contains the recorded message "point to the duck". When a card is inserted into a slot 16 (Fig. 1, not shown) in the machine, the sound tracks pass beneath three respective pick-up heads 42 of which is connectible to a common load speaker, but only one of which can be connected at any one time. When the card 32 is first inserted a mioroswitch M1, Fig. 3, starts a motor to drive a card-feed capstan 40 and also starts an electric timer. When the card's leading edge passes a second microswitch M2, the timer is stopped. The timer generates pulses whose period of repetition is small in relation to the time of transit of a card's leading edge between the switches M1 and M2. The number of pulses given is thus a randomly selected number, and it is this number which governs the connection of one of the pick-up heads to the loud-speaker. If the correct screen is subsequently touched, the loud-speaker remains connected and the card is ejected by re-energization of the motor driving the capstan 40- which will have stopped when the trailing edge of the inserted card left switch M1. Such ejection after a correct selection causes the pick-up head to reproduce the message "that's right" from the sound track on the card. If the user does not make a correct selection, the card will be ejected but the pick-up head will not transmit the "that's right" message to the loud-speaker. Suitable logic circuitry (Fig. 4, not shown) controls the above sequence of operations.

Abstract: 1340000 Drying webs POLYTYPE AG 1 Dec 1971 [4 Dec 1970 1 June 1971] 55798/71 Heading F4G [Also in Division B8] A web of material is supported by an air cushion of hot or cold air produced by an airflow device comprising two convex surfaces disposed between two flat parallel walls, the air flowing out of the space between each convex surface and flat wall and at least some of the air flowing initially around each convex surface towards the other. In Fig. 1, air is supplied at 11 and 12 to tubes 1 and 2 disposed in a channel 4 and having their ends closed.

Air is removed by suction through tapering slots 6 in a support plate 5 comprising two parts tapering inwardly and towards the base of the channel 4. The web 14 is supported between two parallel but staggered rows of air-flow devices. Other forms of air-flow device are shown in Figs. 7 and 9, several devices being supplied by a common air reservoir 24. If the web is halted, the air flow is reduced.

Title: Demand heart pacer
IPC: H03K3/355
Filed: 1974-12-24
Abstract: 1495949 Heart pacers ARCO MEDICAL PRODUCTS CO 24 Dec 1974 [4 Jan 1974] 55879/74 Heading A5R A heart pacer for producing heart stimulating pulses in the absence of naturally occuring heart pulses, is provided with a facility whereby an indication of the voltage of a power source is indicated by a comparison of a constant heart-beat rate produced by a stimulating means, when an inhibiting means is decoupled, and a voltage-dependent heartbeat rate, produced when the inhibiting means is connected. As shown Fig. 1 an oscillator 15 provides heart stimulation pulses to a lead 10 through a voltage multiplier 17. Heart or stimulation pulses are fed on a line 18 through an amplifier 20, to a clamp 21, rejecting spurious signals occurring during a refractory period. Valid pulses trigger a one-shot multivibrator the output of which inhibits the oscillator 15 through an inhibitor 25 and rests the clamp 21. In detail Fig. 3 the oscillator section 15 produces pulses on the charging and discharging of a timing capacitor 100 by MOS devices 102, 104, 115, 116; the pulse width being determined by MOS devices 135, 136. The charged voltage of the capacitor 100 is determined by a regulator comprising FET device 125. The output pulses from the oscillator section are applied to the multiplier section 17 wherein transistors 150, 155 build up charges on capacitors 152, 163 which are combined and presented at the output terminal 36. The preceding circuitry comprises a voltage stabilised "fixed rate" heartpacer circuit. A "demand" capability is provided by connecting heart and stimulation pulses through a lead 173 to the amplifier section 20, the output of which is applied to the one-shot multivibrator section 24. The output of the multivibrator section is fed back to an FET 240 forming the refractory clamp section 21 which blocks any signal from the amplifier section 20 for the duration of the negative output from the multivibrator section 24. The output from section 24 is also fed to the oscillator inhibitor section 25 wherein an FET device 228 drives a point A in the oscillator section 15 to a positive potential causing the discharge of the capacitor 100. With reduction in the voltage of a supply battery, not shown, the time of conduction of FET device 228 will decrease so that the frequency of the oscillator section 15 in the demand mode will increase. The state of the battery is checked by the closure of a reed switch 223 by an externally applied magnet whereby the oscillator section is placed in the "fixed rate" mode and the frequency compared with the heart-rate in the "demand" mode (when the heart is not continuously self-pulsing).

Abstract: 1380758 Refrigerating STAL REFRIGERATION AB 8 Dec 1972 [22 Dec 1971] 56685/72 Heading F4H In a compression-condensation refrigeration system, oil and refrigerant pass from the compressor 2 through a line 16 to an oil separator 3 from which the refrigerant flows to a condenser 5 and thence through a line 8 to an oil cooler 7 before return through a line 11 to an intake 10 in the compressor which is located at a point where the pressure substantially corresponds to the pressure of the refrigerant when it leaves the oil cooler. A regulating valve 9 in the line 8 controls flow of refrigerant to the cooler in response to the temperature of the refrigerant either on the outlet side of the cooler or the compressor as sensed by thermostats 17, 17<SP>1</SP>. A constant pressure valve 12 may be located in the line 11. As shown, a pump 13 passes the oil from a container 4 through the cooler to the compressor for lubrication purposes, the oil and refrigerant being maintained in separate paths (Fig. 5). Alternatively the oil and refrigerant are mixed together in the oil cooler to cool the oil, the vapourized refrigerant and oil returning separately to the compressor.
