Title: Electric shaver comb and method of making same
IPC: B26B19/38
Filed: 1962-07-13
Abstract: 950,426. Making electric shave combs. SUNBEAM CORPORATION. July 13, 1962 [Sept. 12, 1961], No. 27047/62. Heading B3A. A method of making a comb for an electric shaver, said comb comprising a channel-shaped elongated member having two opposite sides interconnected by an integral bridge portion and having hair receiving apertures therein, comprises interconnecting the opposite sides by welding a support means therebetween and hardening said member. A support 11 having an opening 26 and a stud hole (not shown) positioned between said opening and each end of said support is spot welded at 12 to a U-shaped comb 7. The welds along each side of the comb are positioned from each other by punched reliefs, notches or cut-outs 27, 26<SP>1</SP> formed in the bottom edges of the comb. The intermediate pairs of welds are positioned between the opening 26 and the stud holes as well as between the cut-outs 26<SP>1</SP> and 27. Prior to welding the comb is ground and after welding is hardened and tempered. The top of the comb has a central groove 28 which separates the comb into two sections, each of which has alternated punched slots or apertures 29 and comb teeth 30.

Title: Improvements in or relating to circuit-arrangements for synchronizing an oscillator to a control-oscillation
IPC: H03L7/08
Filed: 1952-11-03
Abstract: 713,407. Saw-tooth generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 3, 1952 [Nov. 6, 1951], No. 27616/52. Class 40 (6). [Also in Group XXXV] A saw-tooth generator, Fig. 2, comprises a condenser 12 charged through a resistor 13 and discharged through a blocking-oscillator valve 11. The condenser voltage is applied to an output valve 19 which feeds the scanning coils 26 through an anode transformer 20. A secondary coil 21 feeds a series-tuned circuit comprising a variable inductor 22 and condenser 16, and the sine-wave voltage across this condenser is compared in phase with the sync pulses 25 in the phase-comparer 18 which provides an automatic frequency-regulating voltage for the grid of the valve 11. As the actual moment of release of the valve 11 is dependent on the sine-wave voltage fed back to the grid through condenser 15 from the condenser 16, the natural frequency of the generating system is variable under the control of the inductor 22. Moreover the phase of the voltage fed from the condenser 16 to the phase-comparer 18 is simultaneously varied as the inductor 22 is adjusted.

Abstract: 961,603. Stuffing-box substitutes. SPERRY RAND CORPORATION. July 24, 1962 [Aug. 16, 1961], No. 28367/62. Heading F2B. In order to prevent leakage of pressure fluid from one to another of a number of passageways, each comprising ducts 26, 90 or 82, 94 terminated in ports 76, 92 or 81, 96 located in adjacent mating surfaces 78, 88 which move relative to each other to selectively align the ports of corresponding ducts of the same passageways for the transmission of pressure fluid therethrough, the surfaces 78, 88 are interleaved, e.g. as at 101, 106,102, to provide between the port locations of adjacent passageways a labyrinth passage within which a low pressure region is established so as to drain off any fluid leaking from the passageways. The surfaces 78, 88 are respectively formed on a rotary punch drum 10 and a stationary side plate 70 of a card punching apparatus similar to that disclosed in Specification 961,601. Pressurized air is conveyed from a supply source 93 through a selector 91 to the ducts 90, 26 to actuate a number of punches 60 arranged in columns I, II, III and in longitudinally extending, circumferentially spaced rows around the periphery of the drum. The punches are thereby extended through a card 12 into aligned holes 64 in a rotary die drum 14. The punches are retracted by applying air pressure through the ducts 94, 82, 42, the exhaust being returned via a hollow core 62 of the drum 10 and a passage 80 in the drum shaft 72 to the low pressure side of the supply source 93. The labyrinth passage between the surfaces 78, 88 is connected through duets 110 to 114, Fig. 4, and a manifold 115 in the side plate 70 to the low pressure side of the supply source 93. In a modification, Fig. 7, a number of low pressure manifolds 134 are arranged in the punch drum 10, one for each pair of groups of the ports 76, 81, and are connected through ducts 129 to 133 to the labyrinth passage between adjacent ports of a group. The low pressure manifolds open at 135 into the hollow core 62 of the drum and are thus in communication with the low pressure side of the supply source 93. In another embodiment, the mating surfaces may be formed on members reciprocating relative to each other and are provided with interleaving straight parallel protrusions.

Fig. 2 shows the ring 8 formed in three parts, the part 1 which is inserted last being so formed in relation to the adjacent ends of the other two parts that it can be easily swung into position. It is then secured by a plate 13 welded over the joint 12. In another arrangement, the joints are in parallel planes. The rings 7 press flanges 5 on the rings 3 against the flanges 4 in the casing. The rings 3 and the hollow valve disc 2 are water-cooled. The left-hand side of Fig. 1 shows a known arrangement.
