Title: Improvements in or relating to accounting apparatus for application to typewriters or the like
IPC: B41J11/54
Filed: 1955-02-15
Abstract: 764,780. Typewriters. PAILLARD SOC. ANON. Feb. 15, 1955 [March 2, 1954], No. 4436/55. Class 100(4) . Feed-roller rotation. Automatic line spacing. An account card feeding apparatus for mounting on the carriage of a typewriter or like office machine comprises a device for reversing the direction of rotation of the card feeding rollers 13, 14, Figs. 1, 2, 3, enabling a single spring drum P to drive them in two directions, the rewinding of the spring 78 of the drum P being affected by a friction device 57, 58, and a governor being provided for controlling the speed of expansion of the spring 78. The motor for winding the spring is also used for carriage-return actions wherein a carriage returning drum, when clutched to the motor, winds a draw cable 163, which firstly pivots a lever 166 (Fig. 7, not shown) to effect automatic line spacing and rotates a drum 48, Fig. 3, about its spindle 41. Rotation of a drum 48 continues until the end of the cable 163 is radial to the drum which is thus prevented from rotating and the carriage is returned. The rotation of the drum 48 winds up the spring drum P through gearing 49, 50, 53, hub 54, the friction device 57, 58 and a pawl and ratchet 68, 69. The spring drum P however, does not yet function to drive the rollers 13, 14 in either direction. If it is required to feed cards into typing position, a key 156 is pressed, which causes an axial movement of a piston 101 and connects the spring drum P to a wheel 95 of the reversing device comprising discs 96, 97, hub 98, driving fingers 105, toothed wheel 95 and a wheel 110. The wheel 95 is mounted on a hub 93 coupled to the speed governor and brake drum by a pinion 92 and worm 91, and, through a differential gear arrangement, to the feed rollers 13, 14. When the machine is conditioned to eject cards the drive from the reversing device reaches the rollers 13, 14 through the wheel 110, gears 109, 111, 113, and the differential gear arrangement. After typing, movement of the cards is controlled by a knob so that either, (a) both front and rear cards are expelled, or (b) front or rear-card advances one line space while the other is rejected. 'Further, both cards may be advanced by one line space. The spring drum may, if required, be wound by a single stroke of a manual lever M attached to the shaft 44. Feed-rollers. The feed-rollers 13, 14 have some parts covered with emery powder and co-operate with counter rollers 23 pivoted to the end of a spring blade 24 secured in the partition 17. Card guiding arrangements. The cards are guided into funnels 15, 26 by transversely adjustable guides 19, 28. Bottom margin indicator. A vertical scale provided with graduations 38, Fig. 2, and comprising a cursor 40 to indicate the number of lines left for typing, is secured to the rear plate 27 of the funnel 26.

Title: Reverberation meters
IPC: G01H7/00
Filed: 1975-01-27
Abstract: 1497395 Reverberation meter GENERAL ELECTRIC CO Ltd 27 Jan 1975 [1 Feb 1974] 04872/74 Heading G1G A reverberation meter comprises a transducer for detecting vibrations of a medium energized by a vibrator, a store for registering the magnitude of the transducer output signal just before deenergisation of the vibrator, a comparator for producing a control signal when the vibration has decayed to a predetermined fraction of the magnitude represented by the stored value, and a timer for indicating the time from said de-energization to production of the control signal. In the Fig. 1 embodiment, loud-speaker 17 is energized by warble-tone generator 15 for some ten seconds to produce a steady sound level about 40dB above ambient noise in a room whose reverberation time is to be measured. The sound level detected by microphone M is stored as a voltage on capacitor 20. Switches S2a, S2b, S2c are then operated to de-energize the loud-speaker, connect the microphone to a 30dB gain amplifier 22, and gate clockpulses from a source 32 to a threedecade counter 34, 35, 36. Amplifier 22 output is full-wave-rectified at 23, 28, 29 and smoothed at 31. Comparator 13b compares the smoothed signal with the capacitor 20 voltage and its output changes state when the prevailing sound level has decayed to - 30dB of the initial steady level. The change of state trips latch circuits 34b-36b so that the current contents of the counter are held for display on 7-segment displays 34d-36d. The clockpulse rate of source 32 is such that the display registers twice the time for the - 30dB decay, i.e. the time displayed represents the time for decay to -60dB, namely the reverberation time of the room. In the event that the sound level crosses the -30dB threshold more than once, the latches ensure that the display registers the time at which the sound level drops below the - 30dB threshold on the last occasion. A memory device may record the time to the first occasion on which the - 30dB threshold is crossed.

Title: Improvements in or relating to audible speed indicators
IPC: G01P1/10
Filed: 1927-02-21
Abstract: 290,741. Magni, K. G. Feb. 21, 1927. Acoustic speed indicators; particular speed alarms.-A device for indicating by sound signals that the speed of a machine has fallen below a certain limit comprises a pendulum 2, the hub 4 of which is loosely mounted on a shaft 5 of the machine in such a way that impulses are imparted to the pendulum. The pendulum has a transverse part 3 provided with a race 9 in which a ball 10 is adapted to roll between a pad 11 and a surrounding bell 1. A flat 8 in the hub 4 is engaged by cams 6, 7 on the shaft 5 to produce the impulses. So long as the frequency of the impulses corresponds roughly with the natural period of oscillation of the pendulum, the swing of the latter will incline the race 9 sufficiently to allow the ball 10 to roll into contact with the bell 1 upon each oscillation. At higher speeds the sounds will cease, but they may begin again when a multiple of the speed has been reached. The method of imparting impulses from the shaft 5 to the pendulum may be modified, and the ball race 9 may be bent. In a modification, the pendulum itself may strike a lug on a stationary bell at certain speeds, and, in a further modification, a hammer on the pendulum is thrown out against a bell.

In a system for automatically steering a selfpropelled land vehicle in one direction or the reverse, units at the front and rear of the vehicle, which detect deviation to one side or the other of a guide path, are adjusted about vertical axes in correspondence with the steering. In Fig. 2, a three-wheeled self-propelled industrial truck 10 follows a buried energized conductor 22 by virtue of electromagnetic interaction with a pair of detector coils 27 attached to a single steering wheel 12 at the front of the truck. The rear of the truck is supported by a pair of non-steerable wheels. Amplified signals from coils 27 control a reversible motor 18 which adjusts the steering wheel about a vertical axis by means of a chain 20 to maintain the truck on course. In order that the truck may be run backwards, a trailer 40, attached to the rear of the truck and running on a caster wheel 44, carries a further pair of coils which are rotated by motor 18 through a chain 52 and may be substituted for coils 27 by the operation of a switch. Dimensions and drive ratios are chosen so that the steering characteristics are the same for forward and reverse operation. Constructional details of an easily detachable trailer are given.
