Title: Improvements in hydraulic torque converters
IPC: F16H41/28
Filed: 1956-06-27
Abstract: 875,286. Making hydraulic torque converters. GIRI DE TERAMALA, P. M. Aug. 23, 1957 [June 27, 1956], No. 19913/56. Class 83 (2). A method of making a vaned member of an hydraulic torque converter comprises forming each vane from thin sheet material and bending said sheet upon itself or by securing a plurality of said sheets together to form the opposite sides of the vane, and mounting one or more of the vanes so formed between an inner supporting member and an outer shell, the vanes, the inner supporting member and the outer shell being so dimensioned as to form an interference fit. The vanes of the impeller I and the turbine T are mounted between the inner supporting member G and the outer shell H. The vanes are formed by bending as shown in Figs. 4 and 5 and welding at W.

Title: Improvements in or connected with electrical re-set driving devices for clocks and other mechanism
IPC: G04C13/04
Filed: 1927-07-27
Abstract: 296,181. Mercer, T., and Mercer, F., (trading as Mercer, T. & F.). July 27, 1927. Electric clocks.-In a master clock including a pendulum a and a gravity arm e which reenergizes the pendulum and closes a secondary clock circuit u, the gravity arm is re-set by an electromagnet m, the action of which is delayed. A pawl b on the pendulum drives a count wheel c having a deep notch d. When the pawl reaches this notch it moves an arm h pivoted at i to release a hook j on the gravity arm e (pivoted at f) which falls and, through its roller k, gives an impulse to a pallet l on the pendulum. At the same time an extension y on the gravity arm closes contacts x<1>, y<1> to complete a circuit through battery t, secondary clocks v, extension q (also on the gravity arm), y<1>, x<1>, auxiliary magnet w. through the frame to m<1>, winding of reset magnet m and line u. The action of the magnet w and spring w<1> keep the armature n of magnet m unattracted in spite of the winding m being energized. As the gravity arm continues to sink the arm y is flexed and contact r closes, short circuiting the auxiliary magnet w. Magnet m now attracts its armature and resets the gravity lever, which thereupon opens the circuit u. In a modification the auxiliary magnet is dispensed with and the circuit u is tapped off the battery t.

Abstract: 797,858. Juice extracting. DENNIS, N. S. June 28, 1956, No. 20031/56. Class 28 (2). Co-operating pairs of hemispherical cups 25 rotate planetwise around an axis, each pair turning outwards to admit an orange, and then turning inwards to grip the orange which is then traversed against a fixed knife edge 94 to halve the orange as the knife passes through the space between the cups. An inclined surface 96 holds each half in its cup until a further, curved piece 97 presses the bottom edge of the half within resilient retaining fingers 98, Fig. 7, and the top edge is retained by a pin 101. The cups then rotate round and open apart to engage each half with a spherical rotated reamer, which bores and scrapes out the juice and pulp as the cups turn in again. The skin halves then travel up in their cups to meet ejector spoons 102a which prize out the halves 27. The pulp and juice runs down into a housing 118, Fig. 4, containing a sieve 119 with internal rotated pulp scrapers 120 which passes out at 128 while the juice flows out at 126. The cups are turned in and then out by cylindrical cam grooves 71, Fig. 9, having a cam follower 70 which is eccentric to the cup shafts 69.

Title: Method and device for evaluating a pulsatory signal
IPC: H04L25/03
Filed: 1971-04-19
Abstract: 1287715 Digital transmission systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [23 Jan 1970] 20071/71 Heading H4P In a method of establishing a decision by comparing the value of a pulsatory signal in a synchronous baseband system with a threshold which is varied through a feedback loop, an inequality is also established between the same signal and a fixed threshold during the decay time of the pulse in the feedback loop which when established is passed on as the correct decision. A practical embodiment has a first counter 5 for storing not more than q successive equal decisions in relation to the variable threshold, and a second counter 6 storing not more than n unequal decisions relating to the same signal element, the first counter resetting the second to zero and connecting to an output decisions relative to the variable threshold when the first counter reaches position q and a second counter connecting to an output decisions relating to the fixed threshold when it reaches position n. Signals on an input 1 pass through a linear filter 11, 9 sampler 12 fed with pulses on input 2 at instants (t1 + mT) and a comparison circuit 13 which also receives a variable threshold through a filter 15, having a pulse response s(t), and having an output to a contact 14 and through a delay 16 of time t1 to contact 17. Input signals also pass through a further linear filter 21, a sampler 22 also fed with pulse from input 2 and a comparison circuit 23 also receiving a fixed threshold 25 the output connecting with a contact 24 and through a delay 26 of time t to contact 27. Circuits 13, 23 are also connected to a modulo- 2 adder the output from which is commoned to the q counter 5 through inverter 4 also to n counter 6. Counter 5 is reset when a "1" appears at the output of adder 3 the number of 1's being counted in 6. When n unequal decisions is reached a "1" is applied to points 8, 33 which causes switches 9, 34 to reverse their position. After application of at least q decisions switches 9, 34 occupy the position shown, contact 9 being closed by the signal on point 17 and switch 34 being closed by the signal on point 32 delayed by a time t2 in delay 31. After n unequal decisions are counted in 6, signals at points 8, 33 reverse the switches. The setting of switches 9, 34 may be prevented in that counter 5 counts q equal decisions sooner than counter 6 counts n unequal decisions. Since n decisions control both switches simultaneously it is necessary to choose the delay times t1 t2 so that erronous decisions do not appear at output 10.

Abstract: 573,803. Recording telephone conversations. SOUNDSCRIBER CORPORATION. Dec. 16, 1943, No. 21119. Convention date, Nov. 21, 1942. [Class 40 (iv)] In a system for recording telephone conversations, in order to balance the effect of strong and weak voice currents, the telephone line is connected to a high resistance primary circuit, while the secondary circuit which leads to the input of a recorder amplifier is shunted by a copper oxide rectifier which is biassed by a direct current voltage derived from the output of the amplifier by means of a second copper oxide rectifier. The unit described is intended for use with the dictating machine disclosed in Specification 558,552, to which it is connected by plug couplings, and a two-way switch 37 serves to connect up a telephone line for recording conversations or a local microphone for dictation. As shown in Fig. 2, the telephone line is connected through resistances 20, 21 and condensers 22, 23 to the primary of a transformer 27. The secondary is connected over a variable resistance 33 to the " telephone " terminals of the switch 37 and is shunted by a rectifier 66, while a second rectifier 67 connected by a plug 71 to the output of the recorder amplifier supplies a biassing voltage to the rectifier 66 to effect volume control. A condenser 79 co-operates with the resistances in the circuit to. filter the amplifier output, and an additional condenser 81 may be provided when necessary to cut out the higher frequencies. In a modification, Fig. 3, a pair of shunting rectifiers 83, 84 are arranged in pushpull, while in another arrangement, Fig. 4, the telephone currents are applied through an amplifier 92 to a pair of resistances 95, 96 constituting a voltage divider, the rectifier 97 being shunted across the resistance 96.
