Title: Improvements in and relating to appliances for increasing audibility of sounds for partially deaf people
IPC: H04R1/10
Filed: 1939-05-12
Abstract: 528,662. Hearing-appliances. JONES, J. J. May 12, 1939, No. 14169. [Class 81 (ii)] An appliance for assisting the hearing of deaf persons comprises a sound box P of any desired shape, but preferably in the shape of a drum, adapted to be held in the hand or suspended from the person of the user, one of the end walls A of the box being provided with a series of holes B controlled by a slide or slides C, and a rotatable hollow attachment J secured to the periphery of the box, which attachment is either of such a shape that it can be inserted directly into the ear, or is provided with a single or bifurcated tubular extension, the end or ends of which can be inserted into the ear or ears. As shown, the slide C is formed in two overlapping halves which work in guides D, the seal E for the lower half being raised above the end wall A by an amount equal to the thickness of the upper half of the slide, so that the lower half of the slide is free to pass over the upper half until a projection F on the upper edge of the lower half engages with a projection G on the upper edge of the upper half when both halves lift in unison. In a modification, the sound box is formed in two halves which telescope one into the other so that the distance between the end walls can be adjusted.

Title: Integrating apparatus
IPC: A01B49/04
Filed: 1962-04-12
Abstract: 993, 359. Measuring torque electrically. DAYSTROM Inc. April 12, 1962 [May 9, 1961], No. 14245/62. Headings G1N and G1Q. [Also in Divisions G4 and H2] Apparatus for time-integrating a primary force, comprising a transducer which converts the force to a direct, current which drives a motor in a direction corresponding to the direction of the force, which motor rotates a shaft driving a D.C. generator, the output of which is applied to the transducer to balance the force; includes a feedback path through a surge capacitor through which the direct current can operate to create a temporary balance during the delay in starting of the motor. The shaft rotations are counted to give the integral. In the watt-hour meter shown the force is a torque on a shaft 11 produced by an electrodynamometer 10. A coil 29 fixed to the shaft is positioned between the poles of a permanent magnet 31 which also has an electro-magnetic winding 33. An oscillator in an amplifier 37 applies a high frequency A.C. current to the winding 33. When a torque is applied, the coil 29 is deflected and an A.C. current of magnitude and phase proportional to the magnitude and direction of the deflection is supplied via the lines 35, 36 to the amplifier 37. A discriminator 38 detects the direction of phase change and produces a steady D.C. output on one of two lines in accordance with this direction. The output is amplified at 41 and used to energize one or other of two power relays 42, 43 to open the corresponding switch 47 or 48. This causes a phase change in the A.C. current, produced by a source 52, in one of a pair of field coils 54, 56 of a motor 13 thus setting it in rotation in one direction or the other. The drive shaft is connected through mechanical links 14 to a tachometer generator 16 and to a mechanical or electrical counter 17. A resistor 61 and a thermistor 62 ensure that the tachometer is of constant resistance. The output of the tachometer is fed back to the coil 29 through wires 35, 36 to provide a returning torque to the coil. As this return torque will be slow in acting due to the inertia of the motor, the output of the discriminator is tapped and fed back through a blocking capacitor 39 through which a surge of current can act to provide a temporary balance while the motor is starting. Specification 754,130 is referred to.

Abstract: 623,923. Horticultural cloches. HAWES, H. L. May 30, 1947, No. 14364. Addition to 609,800. [Class 20(i)]  A cloche of the kind described in the parent Specification comprising corner members 13, intermediate members 17 and panes of glass held together by flexible and resilient tying means, and roof panes 10 held in place by resilient and flexible tying means 11, has slidable members 15 threaded on the tying means 11 and provided with hooks 16 which engage the edges of the panes 10. The members 15 exert a bearing pressure on, and the hooks prevent displacement of the panes. The members 15 may be made of wood, plastic or fibre. They may be slid along the tying means, to allow a top pane to be displaced for ventilation. For long cloches, a bent wire member 18 provided with an eye 18a for the tying means may be attached to a member 17. The use of the hooks 16 and this member 18 tends to draw the tying means out of a straight line and thus further extend the springs 14 and increase the security of the top panes.

Abstract: 796,560. Photographic cameras. DECKEL, H., and DECKEL, F. W. May 10, 1956 [May 11, 1955], No. 14566/56. Class 98(1) In a photographic camera having a shutter speed setting ring and a diaphragm setting ring, one ring is provided with a light value scale and the other with a film speed scale co-operating therewith. Preferably, a marker is provided on the film speed scale to indicate the speed of the film contained in the camera and the light value scale is set to this member as to an index. Shutter speed and diaphragm aperture scales are also provided on the appropriate ring and co-operate with a fixed index on the camera body. After the light value has been set the shutter speed and diaphragm rings may be locked for rotation together to set any of the paired values of shutter speed or diaphragm aperture. The locking may consist in a tooth on the resiliently urged diaphragm ring engaging one of a number of notches in the shutter speed ring (Fig. 1, not shown) or the film speed marker may consist of a resilient arm 50 having a projection 52 engaging the knurling of the shutter speed ring 11 and tongues 53 engaging slots 54 in the diaphragm setting ring 12. By slightly bending the resilient arm 50 the locking may be disengaged and, by further bending, the marker becomes displaceable over the film speed scale 22. The light value scale 21 which corresponds to a similar scale in exposure meter, and the film-speed scale 22 are linear and any change by a single unit doubles or halves the exposure of the film.

Title: Packaging machine and method
IPC: B65B11/52
Filed: 1966-04-01
Abstract: 1,099,879. Packaging-machines. AMERICAN PACKAGING CORPORATION. April 1, 1966 [April 5, 1965], No. 14630/66. Heading B8C. [Also in Divisions B6 and F2] Display containers are formed of a cardboard sheet 8, Fig. 1, having two apertures through which two pockets in a sheet of plastics film protrude respectively, the assembled parts being supplied from a magazine 6, Fig. 2, by suction cups 160 of a transfer device 3 on to an intermittently moved conveyer 2 where an article is inserted into one of the pockets by an operator before the conveyer carries the filled container forward to a sealing press 4. The conveyer 2 and transfer device 3 are driven through a transmission device 5a, and the press 4 through a similar device 5b, by means of an electric motor 13. Machine parts are controlled automatically by cam-operated switches which actuate control circuits. Folding and transferring.-Each card 8 in the magazine 6 is pre-scored along a line 9. As the cups 160 grip the lower half of the card, the upper half is temporarily held by rollers 450, thereby bending the card about the line 9. The cups 160 carried on the ends of shafts (149, 150), Fig. 4 (not shown), are enabled to pivot about the longitudinal axes of the shafts by the action  of gear segments (146, 147) which engage teeth (143, 144) on a feed shift rack (140). The rack (140) is moved along a feeder bar (95) by means of a ring (115) which is cam-operated through  intermediate linkage to cause the cups to pivot into engagement with a card 8. The feeder bar (95) is then rotated, causing the shafts (149, 150) to turn about the axis of the bar through 180 degrees, while vacuum is applied to the cups. The container comprising the card 8 is thereby deposited in a tray 71, Fig. 1, on the stationary conveyer 2 with that half of the card which was uppermost in the magazine resting on the tray, and the half which was lowermost extending upwards. Support bars (86, 87) may be adjusted to raise or lower the feeder bar (95), and the spacing of the shafts (149, 150) may be varied, in order to adapt the transfer device to cards of different sizes. Sealing press.-As the container is advanced with an article placed by the operator in its upwardly facing pocket, curved bars 11, 12, Fig. 1, fold down its upper part. After an intermediate indexing station, the conveyer 2 positions the filled container between the upper and lower die plates (237, 227), Fig. 8 (not shown), of the sealing press, a recess (246) accommodating the lower pocket. The die is then closed through the transmission 5b, heaters (236, 226) on the platens (235, 225) of the die causing the plates (237, 227) to soften the edges of the plastics sheet in which the pockets are formed, thereby sealing the two halves of the card 8. After the press is opened, the conveyer 2 moves on to deposit the sealed container in a hopper.
